Where is applied
PE is used in almost all areas. The material is the most affordable, widespread and convenient for packaging a variety of items. Many food products, fabrics, clothing, household goods, industrial goods, toys are packed in primary film. Everything is packed in PE, from elite goods to the most ordinary ones. But there are other options for using the film:
- Protective PE is used to pack a large number of goods that are transported later.
- Shrink wrap is used to pack various products before they are sold. Such material has a memory effect, it can shrink under the influence of high temperature.
- In the agricultural industry, PE is used for greenhouses and greenhouses, for covering the land.
- In the construction industry, the film allows you to protect furniture and interiors during renovation work. Roofing PEs are laid for waterproofing. And also the film serves as a wind protection. It can be used in the manufacture of thermal insulation.
- The basis for a variety of bags and bags.
- It is used in production for packaging raw materials and finished products.
- In everyday life for storing food and various things.
- Can be used to protect from the wind in a gazebo or in any other building. It is enough just to cover several sides with this material.
The widespread use of plastic wrap explains its popularity. In the kitchen, everyone has this kind of food packaging material. In houses, the film is kept in case of renovation to protect furniture and things. In summer cottages, it is worth keeping rolls in case you have to cover the ground or update greenhouses. The versatility of the material allows it to come up with all new ways of using it.
How to choose the right plastic wrap for a greenhouse at a summer cottage, you can learn from the following video.
History of origin
The creation of cellophane was caused by a situation that happened in the distant 1900 to a Swiss scientist and textile technologist. Jacques Brandenberger, visiting the restaurant, saw wine spilled on the tablecloth, and the waiter had to replace the linen from the table. As a textile specialist, Brandenberger decided to create a material that would keep moisture out and repel it. All his attempts were in vain, but he managed to create a transparent film that could be placed on top of the fabric.
Success allowed Brandenberger by 1912 to create an apparatus that produced transparent film in large quantities. The scientist named the new product "cellophane", using the words "cellulose" and "transparent" as a basis. Production went well, and a year later Brandenberger opened another factory in Paris, and by 1923 the scientist had signed an agreement with the Americans, and his products spread to the United States.
Despite the great success, Brandenberger cellophane had a significant drawback: it was moisture permeable. In 1927, the American William Church figured out how to fix this problem. He added nitrocellulose processing to the film production process.
With the advent of moisture-proof cellophane, it became possible to use it for packaging food products, which repeatedly extended the shelf life of products. The popularity of cellophane products grew very quickly and conquered new continents and countries. In Russia, the active use of cellophane began in the 70s, when the new material began to be actively used in various fields.
Top manufacturers
There are many manufacturing plants on the domestic market that use modern technologies and high-quality equipment. Most of the enterprises have been operating for a long time, have managed to become real giants in their niche. Large companies have their own trademarks and patents. Most of the assortment is produced by several domestic enterprises:

LDPE, HDPE and LLDPE are produced on the world market by many companies. Let's list the best:
Chevron Phillips Chemical Company (USA). There is a brand called Marlex. All possible types of PE are manufactured at the plant.
Applications
Compared to conventional plastic wrap, the reinforced product is more durable. The material has a three-layer structure and a frame, thanks to which it retains its shape when stretched. In case of accidental local damage to the web, further breaks are excluded. However, you will need to glue the film in order to continue using it without hindrance.
In construction
Reinforced film is used when it is necessary to close doorways in cases of interior decoration work. It is used to cover concrete when it hardens, to protect wood and other building materials from moisture and other adverse effects. It provides the required degree of waterproofing for roofing, foundation or facade work.
This material can be used to quickly build a temporary roof to hide from the rain or create a shelter to house construction equipment. And also it serves as a temporary protection of non-glazed window openings from the penetration of precipitation and cold.
In agriculture and everyday life
Reinforced film is widely used for solving various agricultural and household tasks. It serves as a shelter for gardening equipment, it is used to create durable sheds for transport, covers for various electrical and fuel equipment. It is used to cover vegetable crops in the beds to protect the crop from hail.
And since the film has excellent waterproofing properties, it is used in the construction of artificial decorative ponds and pools. Compaction of the soil of silos is also not complete without reinforced material. In addition, the film is used to cover greenhouses and greenhouse frames. It is covered with haystacks and rolls in order to prevent them from rotting when exposed to atmospheric precipitation.
Manufacturers overview
Reinforced fabrics of domestic and foreign production are presented on the market. Covering material of various brands differs in technical parameters and price. Popular manufacturers include several companies and firms.
- "AgroHozTorg". Engaged in the production of canvases with Vural Plastik reinforcement. They are produced by the three-layer coextrusion method.During the manufacture of the material, improving additives are introduced into the raw materials for all its layers, which increase the longitudinal and transverse strength, as well as the durability of the web.
- Folinet. Korean manufacturer with production facilities in China and Korea. These industries produce films with a high-density polyethylene frame. The upper and lower layers of the canvases are produced using light stabilizing additives.
- "ZOZP" - Zagorsk Experimental Plastics Plant. Produces reinforced covering materials that are highly resistant to ultraviolet radiation. They have different fees and sizes.
- "Protect". A domestic company that produces a film reinforced with a cast plastic mesh. In terms of performance and technical characteristics, the material of this brand is not inferior to canvases from leading import manufacturers.
- Izospan. It is engaged in the manufacture of covering sheets that are resistant to UV radiation and wind loads.
- "Economy". A Chinese manufacturer offering the consumer budget covering materials. Improving additives are not used in the manufacture of the material, which is why it is advisable to use the film only in the construction of temporary structures.
Properties and characteristics
Plastic wrap is produced by many companies. All characteristics and specifications are governed by GOST 10354-82. The basis for the production is polyethylene of various grades and types. The material itself is a product of ethylene polymerization. It has a lot of properties that have already become familiar to most people.
Consider the main characteristics of any kind of PE film:
- Tensile and tear strength. It can withstand a heavy load of 1 m2.
- Steam and water resistant. At the same time, the moisture absorption rate is not more than 2%. It is worth noting that there are types where vapor permeability is present.
- Air tightness. This makes the film an affordable material for airtight packaging.
- Uncolored films transmit up to 90% of the light.
- PE is non-conductive.
- Does not react with most household and industrial chemicals. Not even afraid of strong acids, petrol products, alkalis and oils.
- Does not decompose naturally. Rotting and the formation of fungus are excluded.
- Retains its properties at temperatures from -80 ° C to + 110 ° C.
- Completely safe when used in a domestic environment.
- Under normal conditions, it lasts for several decades.
The dense film is highly durable and allows you to implement various tasks. PE is lightweight, flexible and docile. You don't need any special skills or qualifications to work with film. The material is easy to cut and glue. When stretched, the length of the PE increases, but the width may decrease.
