Mylar film is widely used in the chemical and food industries, automotive, instrumentation, medicine, and cosmetology. It is used to make packaging for liquid products, a sheath for high-voltage wires, and electrical circuit boards. Strength and ductility allows it to be used in the packaging production of correx, stationery, souvenirs, household appliances.
Material features
The important features of the lavsan film are transparency, gas impermeability. Due 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 conventional polyethylene. Lavsan film is durable, in operation atelevated temperature gives only slight shrinkage. It has a high degree of incombustibility (virtually does not burn).
Varieties of film
The range is very large. Films differ in thickness, degree of transparency and color brightness. They are matte, metallized, with a twist effect, holographic. This is not the whole list of lavsan films.
For example, a film with a twist effect has the property of "remembering" its shape. Usually sweets, tablets are wrapped in such packaging.
Shrink wrap shrinks as temperatures rise, tightly wrapping around the product, creating a vacuum effect. Outwardly absolutely transparent, good shine, with high strength, protects the product from negative factors.
Skin film has a hot-melt adhesive surface. Differs in high optical and mechanical properties, interferes with penetration of dust and moisture. Same as blister pack.
Stretch film is easy to stretch, it will take an impressive amount of force to pierce it. At the moment of contact of the layers, they adhere tightly to each other. It finds its use in wrapping pallets, preventing them from breaking.
Laminated film is a combined material based on several layers. Has a long shelf life of the packaged product.
Foam film has a flexible, porous, foam backing. Used for packaging glass, fragile and breakable products, dishes, electrical engineering and microelectronics. Shockproof, anti-scratch andchips.
Metalized lavsan 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 reflects infrared radiation.
A-PET films endure negative temperatures. They are used for the production of packaging for ice cream, semi-finished products, frozen vegetables.
Benefits
Lavsan is quite popular in the industry and has a number of advantages:
- durable;
- crease resistant;
- elastic;
- immune to germs;
- capable of keeping warm;
- no shrinkage;
- does not transmit ultraviolet light;
- inert to chemicals;
- easy 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 lavsan film. It serves as the basis for the manufacture of magnetic recording tape, motion picture film. It is used as an insulating material in a mechanism that runs on electricity. It is used for the production of various cables, car tires, beverage containers.
In engineering, materials are made using this type of film, but it has found its greatest use in construction. Lavsan film reinforces awning fabrics, drive belts and hoses, composite reinforcement. It is used in the production of floor coverings, is the basis of packagingribbons. Included in airbags, geotextiles, banner covers.
This material is also used for packaging perfumes and pharmaceutical products. Recycled due to low decomposition rate.
