The stretching film is made by coating PVA with nano inorganic substances onto polyethylene stretching film, printing, and composite, which solves the technical bottleneck of poor barrier performance of the current three-layer polyethylene co extrusion packaging stretching film without significantly increasing costs.
Biaxially stretched polypropylene stretching film is made by co extrusion of polypropylene particles into sheets, which are then stretched in both vertical and horizontal directions. Due to the orientation of stretching molecules, this stretching film has good physical stability, mechanical strength, air tightness, high transparency and glossiness, and is tough and wear-resistant. Its barrier performance is not only significantly superior to EVOH five layer co extrusion stretching film, but also significantly reduces packaging costs. This not only ensures all quality requirements for sterile packaging for the packaged goods, but also significantly reduces the cost of sterile packaging for food processing enterprises, solving the technical bottleneck of poor barrier performance of the three layer polyethylene co extrusion stretching film in current packaging. It can be used for packaging beverages, fruit juice, milk, soy sauce vinegar, etc. Milk, soy sauce, vinegar, etc.
Stretch film is currently the most widely used printing film, with a thickness of 20-40 μ m. The most widely used is 20 μ M. The main drawback of biaxially stretched polypropylene stretching film is its poor heat sealing performance, so it is generally used as a composite outer layer stretching film. If combined with polyethylene stretching film, it has ideal moisture resistance, transparency, strength, stiffness, and printability, and is suitable for holding dry food.
