The main characteristics of the plastic composite film analysis

the so-called plastic composite film is only through two layer or two layers of common plastic film by composite volume and together of the plastic flexible packaging products, commonly used plastic film BOPP/CPP, PET/PA and so on.

plastic composite membrane mainly include the following categories: food compound film, medicine compound roll film, pesticide compound roll film, seeds of composite film, aluminum foil composite film, lu: su composite roll of film, lid composite roll film, aluminum composite membrane, paper-plastic composite roll film, powder composite roll film, liquid composite film, solid composite membrane, particle composite roll film and other composite roll of film.

the following is a characteristic of plastic composite membrane, and the main performance:

1, the goods have good performance, the composite film has good transparency, koyo, good printing, suitable for decoration, combined with good rigidity, crisp, put shelves effect is good, attract customers;

2, lighter, easy to carry, it can replace part of metal cans, glass bottles, such as packaging container, greatly reduce weight, also facilitate transportation, convenient to carry, at the same time open is convenient;

3, has excellent mechanical properties, it has good tensile strength, impact resistance, tear resistance, piercing, bending resistance, compression resistance and other performance, and good adaptability, is advantageous for the mechanized operation;

4, have good heat sealing, a lot of film, such as stretching polypropylene, polyester, such as poor heat sealing, but the polyethylene composite with good heat sealing, can greatly improve the heat sealing, so the compound film with polyethylene film as lining;

5, good air tightness, moisture resistance, heat resistance. Cold tolerance, incense, uv protection through, such as performance, can effectively protect the goods, especially in food preservation.

6, low cost, on the premise of guarantee comprehensive performance, plastic composite membrane can adopt high low material collocation method to create composite film, so the total cost is low.
