Information

The stretch film is formed by applying PNA coated with nano inorganic materials to a polyethylene stretch film, printing and compounding, and solving the current three-layer polyethylene co-extruded packaging stretch film without greatly increasing the cost. Technical bottleneck with poor barrier performance.

The biaxially oriented polypropylene stretched film is obtained by coextruding polypropylene particles into a sheet and then stretching in both directions. Due to the orientation of the stretched molecules, the stretched film has better physical stability, mechanical strength, airtightness, higher transparency and gloss, and is tough and wear resistant. Its barrier properties are not only significantly better than EVOH five-layer co-extruded stretch film, but also the packaging cost is greatly reduced, which not only ensures the quality requirements of the packaged materials for aseptic packaging, but also greatly reduces the sterility of food processing enterprises. The cost of packaging solves the technical bottleneck of the poor barrier properties of the stretch film of the three-layer polyethylene co-extruded package, and can be used for packaging beverages, juices, milk, soy sauce vinegar, and the like.and the like.

Stretch film is currently the most widely used printing film, generally used in thickness of 20 ~ 40μm, the most widely used is 20μm. The main disadvantage of the biaxially oriented polypropylene stretch film is that it is poor in heat sealability, so it is generally used as a composite outer stretch film, such as moisture resistance, transparency, strength, stiffness and printability after compounding with a polyethylene stretch film. Ideal for dry foods.
