POF shrink film features and physical properties of the introduction
2024-08-05 11:02POF shrink film is an excellent and easy to apply multi-layer film, imported PE and PP as the main raw materials and the necessary functional additives such as smooth agent, anti-adhesive agent, anti-static agent, etc. by co-extrusion blow molding process processing and production, and its special superior performance has been widely used in Europe and the United States and the advanced countries, adapted to the L-type sealing machines, semiautomatic and high-speed automatic sealing machines. The product is available in single-layer and center-folded double-layer films, as well as bag packaging films, with thicknesses ranging from 12-25 microns for selection. It can package regular and irregular shaped products, including: bowls, stationery, books, toys, insecticides, detergents, daily necessities, food, cosmetics, canned beverages, records and video tapes, wood products, pharmaceuticals, health care products and so on.
Main features:
1, high transparency, good gloss, can clearly show the appearance of the product, improve the sense of awareness, reflecting high-grade.
2, POF shrink film up to 75%, good flexibility, can be any shape of the goods packaging, and after a special process of three-layer co-extruded film shrinkage force can be controlled to meet the requirements of different commodities packaging on the shrinkage force.
3, good welding sealing performance, high strength, suitable for manual, semi-automatic and high-speed automatic packaging.
4, good cold resistance, can be at -50 ℃ to maintain flexibility without brittle cracking, suitable for the packaged goods in the cold environment storage and transportation.
5, environmental protection and non-toxic, in line with the U.S. FDA and USDA standards, can be packaged food.
Physical properties: low-temperature weldable flash high, high welding sealing, tear resistance strength, good optical properties, high shrinkage, environmental protection.
(1) environmentally friendly and non-toxic quality superb use of environmentally friendly materials, heat sealing will not produce toxic and harmful gases, in line with the US FDA standards, POF shrink film can be directly packaged food.
(2) tight sealing Hum sealing performance is good Hum sealing performance is good, and welding sealing range, low temperature weldability is good.
(3) high shrinkage rate, the effect is obvious thermal contraction rate of > 65%, for all kinds of shaped products with just the right plastic ability, packaging fit natural.
(4) Sealed packaging, dust and temperature resistance due to the three-layer composite produced by the unique oxygen barrier, airtight, impermeable to temperature, good barrier, and is not easy to stain the dust.
(5) thin and tough thickness uniform specific gravity light, the actual unit cost is low, flexible, tensile strength, impact resistance, not easy to rupture.
(6) Highly transparent, good gloss due to its excellent transparency and gloss, can improve product packaging grade.
