Comparison of physical properties of POF and PE and PVC shrink film
1.What is shrink wrap made of?
Heat shrink film is widely used in the outer packaging of food and beverage, pharmaceutical industry, construction industry, etc.
Its function is to effectively protect the packaged products through strong contraction force to achieve dust-proof, moisture-proof, anti-collision, and anti-loose effects, and to improve the grade of the product.
The root of shrink film roll is plastic products. Most plastics are high molecular polymers formed by polymerization of by-products refined from fossil raw materials such as petroleum.
Thermoplastics, such as synthetic resins in polyolefin systems, are direct products of the petrochemical industry. The so-called polyolefin plastic is a general term for plastics whose monomers are olefins. The material of plastic flexible packaging is a base material processed from petroleum by-products. Such as BOPP, CPP, CPE, IPE, LDPE, PET, PP, NY, toluene, ink, glue, and other materials are all closely related to petroleum.
The common heat-shrinkable films in the market are as follows: POF.PE.PVC.PET and so on. Each type has its place in the market due to its price and performance.
POF vs PVC shrink film
1. Different definitions: this can be concluded from the article
2. Different uses:
The price of PVC is very cheap and the output is very high. It has the characteristics of rainproof, fireproof, antistatic and easy to shape, and is widely used in the building materials industry and packaging industry.
POF is a tear-resistant heat-shrinkable film. It is currently widely used internationally and is an environmentally friendly heat-shrinkable packaging material recognized by the European and American markets. It complies with the US FDA and USDA standards, and is made of environmentally friendly materials. It is an environmentally friendly packaging material that can be recycled and reused. Especially suitable for the pharmaceutical industry and the food industry. The product meets the requirements of “GMP”. It has a soft texture. It has high tensile strength, high tear resistance, and adjustable shrinkage. It is suitable for automatic high-speed packaging machines. It is widely used in plastic beverage supplies, office supplies, books, electronic products, photo frames, washing supplies, Cosmetics, dairy products, video tapes and other products.
3. Adapt to different temperatures:
PVC is poor in cold resistance and may break during transportation, and embrittlement in cold weather. The packaging is easy to deform after a long time. It has poor antistatic ability and is easy to contaminate dust, which makes the product contaminated. POF has excellent cold resistance. , -50℃ is not hard, not brittle, not easy to break.
4. Environmental protection is different:
Compared with PVC film, it is environmentally friendly, non-toxic, degradable, and does not produce toxic gas during heat sealing.
5. Different security:
Compared with PVC film, the four corners of POF shrink film are softer and will not cut the skin after shrinking.
