ZMC cross composite membrane is produced by salivation composite process with high density polyethylene (HDPE) as the main raw material.It is a kind of composite film with high mechanical properties and isotropic and high strength.
1. High tensile strength, good tear resistance, high tear strength of nail rod.
2. The production and use process is environmentally friendly, without any glue and solvent residues;
3. High adhesion fastness, no delamination, and no impact of environmental climate;
4. Good thermal stability and dimensional stability, not easy to be warped or curled by heat.
5. The surface shall be smooth without vertical cross creases;
6. Excellent UV resistance and aging resistance.
The typical application field of ZMC cross composite film is widely used in the waterproof material industry, which can be used as the core layer support material to produce double-sided asphalt waterproof coiled material, or as the surface layer to produce single-sided asphalt waterproof coiled material.
ZMC cross composite film can also be used as packaging materials, which can significantly improve the strength, stiffness and tear resistance of packaging materials. In addition, signs and tear resistant labels that can be used outdoors.

Composites of film refer to materials that are made by combining multiple layers of different films or other materials. These layers can be designed to provide specific properties such as strength, barrier properties, and flexibility, depending on the intended use of the composite material.
Starch and chitosan are both natural polymers used in food packaging, but they have different properties and advantages. Starch is a carbohydrate polymer that is commonly derived from corn or potatoes. It is biodegradable and can be used to create films that are transparent, flexible, and provide good barrier properties. Chitosan, on the other hand, is derived from chitin, which is found in the shells of shellfish. It has antimicrobial properties and can also be used to create films with good barrier properties. Chitosan films can be stronger and more durable than starch films, but they are typically more expensive.
