What is shrink film?
Shrink film is a material made of polymeric plastic film that covers the package tightly when heat is applied. It is a versatile packaging material that is widely used in packaging for food, gift baskets, boxes, toys, books and soap. There are many types of shrink film, with PVC shrink film being one of the most commonly used for shrink packaging in a variety of applications. Polyvinyl chloride is the third most produced plastic in the world. However, in recent years, polyolefin (POF) shrink packaging has gradually replaced PVC shrink film.
- Good sealing
High transparency
Easy to pack
High durability
Environmentally friendly
What is pvc shrink film?
PVC shrink film is a polymer plastic film made of polyvinyl chloride with good transparency, flexibility and durability.PVC shrink film has good UV resistance, temperature resistance and moisture resistance, and can be used in a variety of environments. It can be shrunk by heating so as to cover the package tightly, forming a good seal and protecting the package from external contamination and damage.
PVC shrink film can be used to package all kinds of food, such as meat, fruits, vegetables, candy, chocolate, etc., which can keep the freshness and hygiene of food.
PVC shrink film can be used to package various daily necessities, such as soap, toothbrush, shampoo, cosmetics, etc., which can improve the beauty and added value of the products.
PVC shrink film can be used to package various electronic products, such as cell phones, computers, flat panel TVs, etc., which can protect the products from damage and pollution.
The difference between PVC shrink film and POF shrink film
PVC shrink film and POF shrink film are both multi-purpose packaging materials, but they differ in terms of raw materials, environmental friendliness, transparency, shrinkage and usage.
PVC shrink film is made of polyvinyl chloride, while POF shrink film is made of polyethylene and polypropylene copolymer.
Different transparencyPOF shrink film has a higher transparency, which can better show the appearance and quality of the packaging.
Different shrinkagePOF shrink film has better shrinkage performance, which can cover the package more closely and form a better seal.
Different usesAlthough both PVC shrink film and POF shrink film can be widely used in various packaging fields, they have different features and advantages, so you need to choose according to different packaging needs when using them.
Environmental protection is differentPVC shrink film contains chlorine, which is not conducive to environmental protection. POF shrink film is a non-toxic, odorless, chlorine-free and environmentally friendly material, which is more in line with the requirements of sustainable development.
Several advantages of shrink film
