High Density Polyethylene Packaging Film
Product Description:
| It is a high-strength multi-layer composite film,It is made of HDPE as the base material, adding plasticizer, plasticizer, stabilizer, antioxidant, UV absorber, toughener and other additives through multi-layer co-extrusion blow molding into embryos, and then by multiple pull Stretching, then rotary cutting into a film substrate with a horizontal and vertical distribution of 45 °, and finally through cross-compositing. Due to its cross-stacking structure is different from ordinary single-layer or multi-layer film, it has the thermal stability, dimensional stability, two-way tear resistance, two-way uniform tension and high elongation which are not available in traditional films. |
| It is an extremely versatile, high-performance product line that resists tearing, puncturing, and weathering. Our proprietary, cross-lamination manufacturing process provides considerably tighter gauge control than competitive spun bonded, smoother printing surfaces, and ease in converting. It is so strong that it will not tear, even when nicked, and withstands cold temperature. UV stabilized, the grades hold up well during outdoor exposure and provides superior moisture and chemical resistance making it ideal for cotton packaing. |

Main Fields:
| As a new material field, functional films are also one of the top ten key fields of Made in China 2025, and the awareness in the market is increasing. Nowadays, functional films are not only used in the construction field, special packaging, tape, label, automobile, electronics and other industries, but also in the fields of film filtration, air permeable film, graphene heating film, insulation film, Anti-UV film, biodegradable materials etc.. UPASS, as a leading domestic deep cultivator of polymer functional films, has also entered a stage of rapid development. We believe that UPASS will enter more application fields of polymer films in near future. |
