Composite film recycled plastic particles refers to a new packaging material composed of two or more kinds of film composite together. Composite film is a packaging material developed in recent years. The reason why it develops fast is that a single type of film can not meet the requirements of protecting products and beautifying products. The composite film can learn from each other and become a packaging material with excellent performance. Now there are many varieties of composite film, and the number of composite layers has developed from the first two layers to more than 10 layers.
Composite film is a plastic film as the base material, and then with other materials, such as paper, aluminum foil, cellophane composite. Its main properties are as follows:
1, has good heat sealing, many films, such as tensile polypropylene, polyester and other heat sealing poor, but with good heat sealing polyethylene composite, you can greatly improve the heat sealing, so composite film with polyethylene film as the inner layer;
2. Good air tightness, moisture resistance and heat resistance. Cold resistance, fragrance protection, UV penetration and other properties, can protect goods, easy to preserve food;
3, has good commodity performance, composite film has good transparency, brightness, good printability, suitable for decoration, plus good rigidity, crisp, shelf effect is good, attract customers;
4, has good mechanical properties, has good tensile strength, impact resistance, tear resistance, puncture resistance, bending resistance, pressure resistance and other properties, plus good adaptability, easy to mechanized operation;
5, low cost, it can take complementary material collocation method to manufacture composite film, so the total cost is low.
6, light, easy to carry, it can replace recycled plastic particles for some metal cans, glass bottles and other packaging containers, greatly reduced weight, but also easy to transport, easy to carry, at the same time is convenient to open.
