What is the name of the package with pimples. All about bubble wrap. Agriculture and greenhouses

More than half a century ago, two caring inventors from America created a new material that could become the basis of washable wallpaper - for that time a new word in building decoration. Fortunately, the material turned out to be very light, soft, elastic, transparent and very tear-resistant. For wallpaper, bubble wrap turned out to be unsuitable, and in other areas its properties were found to be very useful. Despite the thin structure, the film made of food-grade polyethylene turned out to be the owner of high heat and moisture insulation. In addition, the film retained its properties in a wide temperature range, namely from -60 to +80 °C.

The film was launched into production, first as a modern convenient packaging material, and then, having finalized the production technology, they offered agriculture an excellent cover material for greenhouses, greenhouses and other shelters when cultivating crops in latitudes with low summer temperatures.

From what, how and what kind of bubble wrap is produced

Due to the abundance of bubbles in the web of material, the film was called bubble, bubble, air, air bubble (WFP). It is made by melting food-grade polyethylene filled with air bubbles that are glued to the base of the film. Interestingly, each individual bubble is always isolated from its neighbors. Damage to it will not affect the quality of the material. It remains flexible and durable.

Air bubble film (hereinafter referred to as WFP) is produced in two and three layers. Two-layer is more often used as a packaging material, easily takes the form of a wrapped part or a finished product, protects against physical damage (scratches, minor chips and cuts). The three-layer film is more durable and can withstand increased loads. It has an increased protective function and minimizes air loss from the bubbles. A four-layer film also enters the open sale.

Bubble bags for protective packaging

In terms of its qualities, the 4-layer runway is heavy-duty, designed for packaging especially valuable devices and other products. It can be designed in different colors from silver to black, with the ability to apply the necessary inscriptions, explanations, logos, etc. on the surface.

Beneficial features

• The exclusivity of bubble wrap is that it is completely inert, freely in contact with food products, does not harm human and animal health, since it does not contain toxic ingredients. Its quality is adapted to repeated use without changing the physical properties.
• The runway is excellent at absorbing shock and friction, acting like a heavy-duty tire.
• Air bubbles are an excellent heat insulator, exceeding the heat-insulating properties of glass by 80, and ordinary film by 120 times. Packaging for the transportation of fruit will reliably protect products from low temperatures, drying out during long-term shelter, waterlogging in rainy weather.
• Bubble wrap freely transmits ultraviolet rays, which is very important for growing products in greenhouses (greenhouses and greenhouses). Thermal insulation properties allow the use of the film in greenhouses with natural heating, especially for keeping warm at night.
• With prolonged use in humid conditions, the film does not become moldy and does not rot. If you cover the pool with such a film at night, the water will not cool down until morning.

Bubble film has found wide application in construction and agriculture.

Construction

• In construction, the runway is used as an independent building material. Polyethylene foam bubble wrap is used in the construction of various roofs. For high fire resistance - in the construction of storage facilities, warehouses, basements. A reliable insulator, the runway serves as the basis for the installation of underfloor heating with electric heating.
• Specialized bubble wrap has additives in its composition that classify it as a group of slow-burning materials. This property contributes to the effective use in the transportation of antique works of art, expensive electronics and other products.

Agriculture and greenhouses

WFP was included in the list of modern cover materials for the construction of greenhouses and greenhouses. Recently, the building materials market offers light-stabilized air-bubble film for greenhouses, which differs from the usual 2-3-layer runway with special additives introduced, prolonging its effective use. This type of film is called "double-glazed" film. It has a higher ability to protect against drops and low temperatures, frosts (with spring shelters) with light weight. Specialized "double-glazed window" runway transmits ultraviolet rays. It contains antifog in its composition, which removes the effect of the lens when moisture drops accumulate on the surface of the film. In addition, antifog counteracts the formation of fog and cold morning dew in greenhouse structures.

A specialized film with reinforcement and antifog is an excellent coating for small greenhouses in the private household of summer residents. Long-term, light, with increased mechanical strength, low thermal conductivity, light stabilizers, it stably maintains the desired temperature and humidity in the greenhouse and hotbeds. Serves without additional repair work for year-round use up to 5 years. And most importantly, WFP is safe for health. This is an environmentally friendly product.

Modification of bubble wrap "oasis" is specially designed for use in the construction of greenhouses and hotbeds. The composition of the film includes phosphor additives that accelerate the processes of photosynthesis, which, of course, has a positive effect on the development of plants and the formation of crops. Under the "oasis" film, the yield without other costs increased on various vegetable crops by 10 ... 50%.

Film "oasis" - is presented on the market in rolls 164 cm wide. It consists of two outer flat layers and an inner one of bubbles, the filling of which is dry air. The film is reinforced, which gives it high strength properties. The length of the rolls ranges from 25 to 100 running meters. Produced modifications have different sizes of air bubbles, which changes its mechanical properties and light transmission. It can be used in combination with glass, with installation in frames on any frame. If only the runway is used for coating, then it is recommended for country small greenhouses - a fine-bubble modification.

Many people ask the question: "What is the name of the film with bubbles?". The answer will be given in this article.

The history of bubble wrap began in 1957. At that time, its first prototype was created by two scientists, Fielding and Chavann. They were approached by an American designer with a request to create a new unique type of wallpaper that can be easily washed and cleaned of dirt. Alfred Fielding, while on the plane and landing at the airport in New York, drew attention to the clouds, it seemed to him that they give softness to the landing of the airliner. At that moment, he was struck by the idea of ​​using bubble wrap as a package, as it would be able to soften bumps and falling objects. In 1960, he and a partner filed a patent for their invention, and they called it Bubble Wrap (bubble shell).

One of the fun with the material was the bursting of bubbles. The process is an alternate squeezing of the air areas, one after the other. This has a general calming effect on the human nervous system and allows you to abstract from current problems. The pleasure is only the effect of a special sound when the material cracks. Also, the speed and number of bursting bubbles bring special joy. Someone likes to do it alone, and some can do it right in the office.

Despite the wide popularity of the product, the Russian language has not yet come up with an unambiguous name for it. What name they just don’t come up with: “pimple”, “pokakatelnaya film”, “thing with bubbles”, “bubble wrap”, polyethylene with pimples” and many other abbreviations can be heard from people. Reading articles about it on the Internet, you can find more serious designs: bubble wrap, bubble wrap, bubble wrap.

Now the income of the company that started the production of a unique canvas is billions of dollars. And the film itself has become part of the public and culture of mankind. Programs for popping air spheres on the screen have appeared in gadgets, groups of fans of this packaging tool are being created on social networks, and in some countries they organize entire competitions for the speedy destruction of bubbles.

Initiative Japanese have created a special gadget that imitates air bubbles. This is a record with 8 buttons that, when pressed, create a popping sound exactly like the popping of an air cavity. In order not to get tired of such an activity, they came up with a number of unusual sounds that are heard if you reach a certain number of claps.

You can buy air bubble wrap in Moscow from Packland. It is made from PVD polyethylene.

How bubble wrap is made aslan wrote in September 5th, 2017

Probably there is not a single person who would indifferently throw this package into the trash. Bubble wrap not only protects the goods on the way from the seller to the buyer, but is also an excellent anti-stress agent. It's hard to resist bursting through all the bubbles after you unpack the box that contains this very film.

Today we will see how bubble wrap is made.

In order to find out how the pimply antistress is made, I went to the production of the company "Beta Couvert", which is located in the Moscow region, Lytkarino.

It all starts with these bags, which contain polyethylene granules. Raw materials of Russian production.

The granules are poured into a container, where a hose is placed that sucks the granules up into the machine, where the plastic is melted and converted into polyethylene. The granules consist of primary - plastic from the factory, and secondary - plastic, which is produced right there.

This is how the granules look in the box. A non-specialist will not understand where the primary is, and where the secondary is.

The granulate is loaded into this machine, which actually makes the film. Machine made in Italy.

During production, all these shafts are spinning, and of course you can’t touch them if you don’t want to lose your hand.

In case of emergency, protection is provided here in the form of such a fuse - a red cord, by pulling which the machine can be stopped instantly.

And this is the main roller that makes the bubble wrap. Above it is a container with a melted granulate, from which two strips of polyethylene flow onto the roller. On the one hand, a smooth roll forms the flat side of the film, on the other hand, a grooved roll forms the pimpled side.

See the tiny holes in the recesses? When in contact with the roller, the still hot film is sucked through the holes into the recess with the help of vacuum, and the same pimples are obtained. Clap clap.

Then the formed bubble film is pulled and goes further along the machine.

This is the second half of the machine. In the middle you can see a block that allows you to make special-purpose bubble wrap with various additional layers.

The film is pulled onto these rollers, where the edges of the film are trimmed (so that the roll is even) and then fed through a shiny shaft for final winding into the finished roll.

Then it is wound into a large roll, the winding can be from 50 to 100m, depending on the needs of the client. Some unscrupulous manufacturers sin by not winding up the film for customers up to 10 m or more. In rolls of film from Beta-Kuvert, the footage always complies with acceptable standards.

After the roll is ready, the film is cut off, the device turns the roll over and immediately starts winding the film on another sleeve. The ends of the film are sealed with adhesive tape and packed in a bag, after which the roll is removed from the pin.

At this time, the worker puts a spool (cardboard sleeve) on the pin for the next roll.

Those spools...

The package with the roll is tied up and taken to the warehouse, from where it will already go to the customers.

Few people know, but there is a bubble wrap with large pimples called Bigbubble. For its production, such a shaft with large cells is used.

Did you know that the diameter of the Bigbubble bubbles is 30 mm, and the density of the film reaches 148 g/m2. This is a great option for packing especially fragile items such as antiques, mirrors, vases.

The lighter in the photo makes it clear how big the pimples are on such a film.

In the next room, the finished film is wound into rolls with a smaller footage.
Airbasic mini-rolls with windings of 5 and 10 meters and a roll width of 0.4 - 1.2 m will become an indispensable assistant:

• summer residents (transportation of jars of jam and other preservation)


• motorists (trunk protection from dirt)


• household (lining for jars and glass containers)

In another room, bags are made from the same film.

Surely in these you received parcels from online stores. They are the main customers of such packaging.

What is the name of the film with pimples for packaging? The answer to this question can be found in this article.

More than 150 years ago, polyethylene products and packaging appeared in people's lives. A lot of research and experimentation has been carried out, thanks to which this product has received the state of the art and has undergone many changes. Today, polyethylene is much different from its prototype and has a large number of unique properties. Among such a wide range on the market, the so-called bubble wrap for packaging stands out in particular. Its name is explained by scientific knowledge in technical textbooks.

The original purpose of using this material was wallpaper for walls. In favor of this appointment, the factors of its easy cleaning and unusual appearance were considered. Despite this, the film with pimples, as they are also called, began to be used for completely different purposes.

The change in the main function of the material was influenced by its property of vapor and moisture resistance, since polyethylene is the main element of the fabric structure. Based on this, it was concluded that the walls covered with this type of wallpaper will not let air and moisture through. This will lead to an increase in humidity in the room and stuffiness. These factors have played an important role in maintaining human health.

Air bubble wrap quickly found its new wide application. It happened thanks to a sudden incident with one of the inventors. Landing at the airport by plane, he noticed the airiness and lightness of the clouds, which gave a soft landing. At that moment, he remembered his invention and noted that the air-bubble film could secure the cargo during transportation and soften falls and bumps. He patented his discovery, which was loved by many manufacturers for the possibility of ensuring the high quality of the transported goods.

And also one of the functions of the material is the coating of greenhouses and greenhouses in summer cottages and farmland. It acts not only as an excellent shelter, but also has soundproofing and insulating qualities. For agricultural needs, many choose ordinary PE film, because the price of 200 micron polyethylene film, so popular among summer residents, is much lower.

One of the entertainments in the offices was the so-called bursting of bubbles. Pimples or pimply film can reduce nerve tension and avoid stressful situations that may appear during the working day. This is advised by psychotherapists and enterprises often organize competitions for the fastest bursting of bubbles.

Bubble wrap packaging material has confidently entered our lives due to its features - air bubbles in the inner layer. This type of packaging is the best for protecting products from shock, moisture, pollution, cold. In the article we will tell you what air bubble wrap is, its properties, varieties, features of production and application.

What is air bubble film, its characteristics

Air bubble film (VPP) is a polymeric material in which smooth polyethylene and a bubble layer are combined. It is also commonly called "pimple", "bubble", "bubble film".

Small spheres filled with air work in compression. Upon impact, the energy of destruction is used to compress the bubble, and not to damage the packaged item. Bubble wrap has heat-saving properties, since air is a good heat insulator.

GOST for air bubble film has not been developed, so the material is manufactured in accordance with TU 2245-001-96117480-08. The characteristics of the raw material from which it is made - high-pressure polyethylene (LDPE) must comply with the requirements of the GOST 16337-77 standard.

The main characteristics of the air bubble film:

• Number of layers. The industry produces 2- and 3-layer air-bubble film. In a two-layer one layer of smooth polyethylene and one - corrugated with bubbles. In a three-layer film, the bubbles are the middle of the "sandwich", sealed between two layers of a smooth polymer material.
• Roll sizes. Standard width of runway rolls: for packing furniture - 1.0; 1.2 and 1.6 meters; for packaging equipment - 0.8 meters; for packing dishes - 0.3 and 0.4 meters. Roll footage: 25, 50 and 100 meters.
• Film Density:

Two-layer: from 45 to 300 g/m2;

Three-layer: from 90 to 260 g/m2;

Covering (for greenhouses) - 83-120 g / m2.

The higher the density, the greater the load the packaging bubble film can bear. Three- and two-layer bubble wrap with a density of 200-250 g/m2 is used to transport computers and radio equipment, thin antistatic (65-90 g/m2) is used for packaging electronic components, a three-layer runway with the addition of antifog (250 g/m2) is covered swimming pools and greenhouses.

You can check this parameter without special equipment. If the density is less than 50 g / m2, then the bubbles are easy to crush with your fingers and no cotton will be heard. At a density of 50-120 g/m2, the sound of a bursting bubble is clearly audible. Packaging with a density of more than 120 g / m2 is difficult to crush with your fingers, and if this parameter is higher than 180 g / m2, then it is completely impossible.

The thickness of one layer of pimply film varies from 45 to 150 microns.

• Air bubble height and diameter. The cushioning properties of the bubble wrap depend on these dimensions. The higher the sphere, the better the material protects the cargo from mechanical damage. A film with a bubble diameter of 6,10,30 mm and a height of 3-10 mm is produced. The most common type of runway is two-layer, with a bubble height of 4 mm and a diameter of 10 mm.
• Temperature range of application. Air bubble film can be used in the temperature range from -60 0 С to +80 0 С.
• Film marking is written as follows:

For example, VP 3-4-75 means:

VP - air-bubble;

3 - three-layer;

4 - bubble diameter, mm;

75 - density, g / m2 (1 meter weighs 75 grams).

Sometimes, at the end of the marking, the footage of the roll is added (25,50,100 m).

Another example of bubble wrap labeling:

Air bubble film modifications

In addition to the usual bubble wrap, there are several modifications of the runway:

• Penobabal is a combination of WFP and polyethylene foam. The material is used for the transportation of expensive goods. This protective packaging is made of 2- or 3-layer bubble film with polyethylene foam backing, 1-4 mm thick. Foam bubble has excellent shock-absorbing and heat-insulating properties, does not let water and dust through, is very durable - it can be used several times.
• Craftbubble is a combination of runway and paper. Conventional bubble wrap stretches in the longitudinal direction, which is not always desirable. After it is strengthened with kraft paper, it does not deform even under the influence of a heavy load. It is used for transportation of antique furniture, mirrors, office equipment. The paper layer absorbs moisture well, preventing the cargo from dampening, so it is better to use Kraftbubble in autumn and spring, when air humidity is high.
• Alububble is a pimply film coated on one or both sides with aluminum foil or polypropylene metallized film. The low coefficient of thermal conductivity (0.007 - 0.011 W / (m * deg) and the good reflectivity of the aluminum bubble make it possible to use this durable (more than 50 years) material for thermal insulation of load-bearing walls, roofs, balconies.

Air bubble film production

The film is made from high-density polyethylene, which is supplied to the production in the form of translucent white granules. Even before the melt, special additives can be added to the granules to prevent the accumulation of static electricity in the finished film.

The mixture is fed into the extruder hopper, where it is heated to 280 0 C. The straightened homogeneous mass is poured out of the extruder in two thin streams. The first stream enters the forming drum. The drum has a perforated surface, the diameter of the holes corresponds to the diameter of the bubble. A vacuum is maintained inside the drum, so the mass is drawn in to a certain depth (bubble height) and solidifies. The second molten flow covers the stamped bubble layer and seals it, leaving air inside the bubbles.

This is how a two-layer runway is made. In the manufacture of a three-layer air bubble film, a third stream of molten polyethylene is passed over the bubbles. When hardening, such a “sandwich” forms a sealed and durable packaging material.

Advantages of air bubble film

Bubble wrap has many advantages, the main ones are:

• Protects the packaged cargo from all environmental factors - dust, dirt, water, damage;
• Protects the product from vibration, mechanical shock, friction, damage when falling due to good shock absorption;
• Retains heat. The coefficient of thermal conductivity of the film of 0.06 W/(m*K) approaches the thermal conductivity of mineral wool - one of the most popular heaters. This makes the runway an indispensable packaging material for the transport of goods that are harmful to the temperature difference.
• Break resistant. Tensile strength of packaging film with bubbles - 70-90 N/m. For comparison, for stretch, one of the main competitors of the runway, this parameter lies within 50 N/m.

Application

Air bubble wrap has many applications:

• Bubble material found the greatest application in packaging. In this film, you can safely transport (at any distance) valuable and fragile things - mirrors, glass, equipment, antiques. Since the runway is made of food-grade polyethylene and has a hygienic certificate, it is used to transport food. Roll material is used for packing large loads (the edges are fastened with adhesive tape), bubble wrap bags are used as containers for phones, accessories, car parts, and plumbing.

Interesting. A new packaging solution has appeared - an envelope with an air bubble film from the inside. They are bought when you need to send an electronic circuit or a lampshade from a lamp, a souvenir or a DVD. For the outer layer, moisture-proof kraft paper is used, for the inner layer, two-layer pimply polyethylene is used. There are 11 standard sizes of "bubble" envelopes - from 100x160 mm to 350x470 mm.

• Film for pools (solar). A two-layer air-bubble film spreads directly on the surface of the water. Thanks to the layer with air bubbles, the material perfectly adheres to the water, protects the pool from pollution, and prevents evaporation. The lower, smooth layer of polyethylene is made in color. The standard thickness of the runway for pools is 500 microns, the thickness of the "package" is determined by the height of the bubble.
• Greenhouse film. This covering material, due to the bubble layer, is an excellent heat insulator. Due to the low weight of the runway, it does not need a serious frame. It is stronger than other polymer films - even if you do not remove it for the winter, the runway can last at least 3 years on vertical surfaces. At the manufacturing stage, light stabilizers, antifog, luminous additive are introduced into the polyethylene granulate. They slow down the destruction of polyethylene, prevent it from fogging from the inside, and convert UV radiation into a blue and red spectrum useful for plants.
• In construction, the runway is used as a steam, hydro and thermal insulation of walls, engineering systems, roofs, floors.

The production rate of bubble wrap is growing every year by 15-20%. The main consumers are furniture manufacturers. They account for almost half of the volume. 31% are taken by companies producing electrical engineering and electronics, 17% - by "dishes" and "glass makers". The demand for these packaging products is huge. In Russia, 25 large enterprises are engaged in the production of multilayer films, including air bubble films, but imports still account for a large share of consumption.
