Lavsan film is widely used in the chemical and food industries, automotive, instrument making, medicine, and cosmetology. They make packaging for liquid products, a sheath for high-voltage wires, electrical circuit boards. Strength and plasticity allows it to be used in the packaging production of corrections, stationery, souvenirs, household appliances.
Material Features
Important features of the film from Dacron is transparency, gas impermeability. Thanks to the smooth surface, various dyes are easily applied to it. The film does not stick, does not change its properties in conditions of high humidity. It has high strength, resistance to punctures and other mechanical damage.
This type of film is more than 10 times stronger than ordinary polyethylene. Lavsan film is durable, in operation at elevated temperature gives only slight shrinkage. It has a high degree of incombustibility (practically does not burn).
Varieties of film
The assortment is very large. Films vary in thickness, degree of transparency and color brightness. They are matte, metallized, with a twist effect, holographic. This is not the whole list of films from Dacron.
For example, a film with a twist effect has the ability to “remember” the shape. Usually in such a package wrapped sweets, tablets.
Shrink film shrinks with increasing temperature, tightly fits the product, creating a vacuum effect. Outwardly absolutely transparent, shines well, with high strength, protects the product from negative factors.
The skin film has a hot glue surface. It has high optical and mechanical properties, prevents the penetration of dust and moisture. Similar to blister packaging.
The stretch film is easily stretched, it will take an impressive force to pierce it. At the moment of contact of the layers, they adhere tightly to each other. It finds its application in the winding of pallets, warning them of destruction.
Laminated film is a combined material based on several layers. It has a long shelf life for the packaged product.
The foamed film has a flexible, porous, foamed base. They are used for packaging glass, fragile and breakable products, dishes, electrical equipment and microelectronics. Shockproof, protects against scratches and chips.
Metallized polyester film has found its application in the insulation of floors, roofs, walls and ventilation equipment. It is based on aluminum and lavsan. The thinner the metal layer of the film, the weaker it beats off infrared radiation.
A-PET films are resistant to negative temperatures. They are used for the production of packaging for ice cream, convenience foods, frozen vegetables.
Benefits
Lavsan in industry is quite popular and has several advantages:
- lasting;
- resistant to creasing;
- elastic;
- immune to the action of microbes;
- able to keep warm;
- no shrinkage;
- does not pass ultraviolet;
- inert to chemicals;
- easy to care.
Application of mylar film
Due to its properties, it has a wide range of applications. Food packaging is the most important, but not the only area of application for mylar film. It serves as the basis in the manufacture of magnetic tape, film. It is used as an insulating material in a mechanism powered by electricity. It is used for the production of various cables, car tires, containers for drinks.
In mechanical engineering, materials are made using this type of film, but it has found the greatest application in construction. Tarpaulin fabrics, drive belts and hoses, composite reinforcement are reinforced with lavsan film. It is used in the manufacture of flooring, and is the basis of packaging tape. Included in airbags, geotissue, banner coverings.
This material is also used for packaging perfumes and pharmaceutical products. It is recycled, due to the low degree of decomposition.
