What is heat shrinkable film?

Heat shrinkable film is used for the sale and transportation of various products, and its main role is to stabilize, cover and protect products.The shrinkage film must have high puncture resistance, good shrinkage and certain shrinkage stress.During shrinkage, the film cannot produce holes.

Type of heat shrinkable film.

New products have been derived from new technologies. The existing heat shrinkable films mainly include PE/PVC/POF/OPS/PET.

What is POF heat shrinkable film?

POF has the characteristics of high gloss, good toughness, high tear strength, uniform thermal shrinkage and is suitable for automatic high-speed packaging. It is the replacement of traditional PVC thermal shrinkage film.POF is the meaning of thermal shrinkage film, POF stands for multi-layer co-extrusion polyolefin thermal shrinkage film, it is linear low density polyethylene as the middle layer (LLDPE), co-polypropylene (PP) as the inner and outer layer, through the extruder plasticizing extrusion, and then through mold head forming, film bubble blowing and other special processes.

POF heat shrinkable film application range.

Widely used in medicine, food, drinks, disinfection tableware, printed matter, hardware plastic products, cultural goods, ceramics, chemical, auto parts, such as this, electronic audio and video packaging of various products, especially in the irregular form of goods or commodities combined (cluster) of packing, can meet the commodity moistureproof and dustproof, touch the sameness, transparent display, and other functions,Can increase the appearance of products attractive, can also be used to replace all kinds of carton, not only save packaging cost, and in line with the packaging trend.Shrink film (bag) can be processed into: flat pocket, arc-shaped bag, trapezoidal bag, three-dimensional bag and other special-shaped bags.

General performance of POF heat shrinkable film.

Primary protection: to provide the surface protection of the product, forming a very light and protective appearance in all aspects of the product, and can achieve the purpose of dustproof, anti-oil, moisture-proof, anti-theft (the specific effect is subject to the packaging effect).In particular, it is important to make the packaged goods uniform force, to avoid uneven force damage to the product.

Compression fixation: with the help of the film thermal expansion and contraction force to cover the product packaging, forming a compact unit as a whole, can effectively prevent the dislocation and movement of internal products in the process of transportation, at the same time, the film retraction force makes the film subsidy exhibits, reduce the volume occupation.   

Efficient packaging: with the function of efficient packaging, after obtaining a satisfactory packaging effect through multiple tests, the automatic packaging machine can be used with film for high-speed online automatic packaging of products.

Environmental protection and non-toxic: no toxic smell is produced during processing, in line with FDA and USDA standards.

POF heat shrinkable film derivative type.

Normal temperature conventional membrane/low temperature membrane/crosslinked membrane.
