Global Plastics News:

plastic film has some advantages that other packaging materials such as transparency, air tightness, moisture resistance, thermoplastic and so on do not have, it has been widely used in the field of commodity packaging. Plastic Composite film improves the shortcomings of plastic single-layer film, thus becoming an ideal packaging material to meet the needs of different commodities.

because plastic film has a certain degree of transparency, air tightness, moisture resistance, thermoplastic and other advantages that other packaging materials do not have, it has been widely used in the field of commodity packaging. However, a single variety of films can no longer fully meet the requirements of protecting commodities, beautifying commodities and processing adaptability, especially for packaging steamed food, various fast food, frozen food and fresh food, because this kind of packaged food is in the international'Supermarket' With the continuous expansion of the demand on, higher requirements are put forward for the performance of packaging materials.

Therefore, a few years ago, people began to use two or more layers of the same or different packaging materials to make composite packaging materials. This kind of plastic composite film greatly improves the shortcomings of plastic single-layer film, thus becoming an ideal packaging material to meet the needs of different commodities.

plastic composite films were originally compounded with cellophane and polyethylene, and later a large number of composite films with different characteristics emerged. They can not only package dry food, but also some wet food and other precision instruments and medicines that need long-term preservation.
