What is the advantage of cross-linked film?

There are several categories of POF heat shrink film, such as cross-linked film, ordinary film, high-end film, etc. Cross-linked film is actually a kind of shrink film. There are many similar protective films in life, which are widely used. So the question is, what is the advantage of cross-linked film?

1. Cross-linked film is actually a kind of shrink film, which is suitable for packaging products with certain special needs, such as electronic products, banknotes, lottery tickets and other special products. The shelf effect of cross-linked film is also very good. It is mainly suitable for mechanical packaging, and it will have obvious effect only when used with a shrinking machine.

2. POF cross-linked heat shrink film has a very good shrinkage rate, and the seal is firm and durable, and the shrinkage temperature range is wider. Surface treatment strength, PE surface tension is extremely low, and it needs to be corona treated before printing, so corona treatment strength is a key indicator for film printing.

3. POF cross-linked film has excellent mechanical properties, such as longitudinal and transverse tensile strength, fracture productivity, etc. POF cross-linked film has excellent tensile properties and is easy to stretch and deform. Various resistances, such as friction resistance, sun resistance, and solvent resistance. For occasions with high hygiene requirements, the film should pay attention to its solvent residue characteristics when printing.

4. Cross-linked film is also an environmentally friendly material. It is an odorless product packaging bag with active active genes. It can react with double bonds, hydroxyl groups and other genes under the action of a catalyst. It is the basic raw material for products such as foam leveling agents, defoamers, and water-soluble silicone oils. It has excellent waterproof properties and can be used as a waterproof agent for glass, paper, metal, ceramics, cement and other items.

In general, cross-linked film has many advantages. At present, cross-linked film is mainly used in various fields of flexible packaging, such as cosmetics packaging. Because the physical indicators of each sample are very good after cross-linking treatment, it is also suitable for heavy packaging and special-shaped packaging, such as home decoration combination product packaging.
