POF shrink film and PVC shrink film difference between the two
POF five-layer co-extrusion shrink film is a gradual rise in recent years and accepted by the people of the new generation of products. Environmental protection multi-layer co-extruded polyolefin POF heat shrinkable film, is a special equipment in the linear low-density polyethylene (LLDPE) as the middle layer, polypropylene (PP) as the inner and outer, with a special process will be, And the outer layer is co-extruded, and the heat shrinkable film having high transparency, high shrinkage and heat sealing performance is produced. It also has all the advantages and strengths of polyethylene (PE) and polypropylene (PP), and its superior performance is far superior to pure polyethylene (PE) film and polypropylene (PP) film, is the current international On the widely used and approved by the European and American market environment-friendly shrinking packaging materials.
It meets the US FDA and USDA standards, all environmentally friendly materials, is an environmentally friendly packaging materials, can be recycled. Especially for the pharmaceutical industry, food industry. The product meets the "GMP" requirements.
PVC heat shrinkable film with ethylene method PVC resin with a dozen kinds of accessories mixed after the second inflated, which is characterized by good transparency, easy to shrink, high strength, shrinkage can be adjusted according to user needs free.
Features The following points:
PVC shrink film with high transparency, good gloss, high shrinkage characteristics.
POF shrink film surface gloss, toughness, tear strength, heat shrinkage uniform and suitable for automatic high-speed packaging and other characteristics, is the traditional PVC heat shrink film replacement products.
POF film is a transparent luster and close to the appearance of the packaging film, its energy saving, high shrinkage, transparent luster, strong anti-tear and other characteristics of the subversion of the traditional packaging film limitations, by the market Welcome, much consumer favorite. POF film for a variety of packaging areas, including the field of food, daily necessities, cosmetics and other areas of multi-field packaging.
POF film advantages can be summarized as the following 5 points, namely:
1, toughness: sealing obvious, good contraction, molecular structure close.
2, high transparency: no pattern, no crystal point, high gloss transparency.
3, the thickness of uniform: sealing temperature between 200-290 ℃, the thickness of uniform.
4, high shrinkage: POF film shrinkage is extremely high, so suitable for a variety of shapes of product packaging.
5, strong cold: POF film even in the minus 20 degrees can also maintain flexibility, product contraction perfect.
POF heat shrinkable film is a transparent luster, high shrinkage, environmental safety, tear resistance of the packaging film, in the production process regardless of stretching orientation, stretching for a variety of shapes, to adapt to a variety of different shapes Product packaging, POF shrinking film packaging close to the surface of the product, in the surface to form a layer of transparent sealed film, firmly wrapped in the periphery of the product, as a layer of protective film.
