stretch film features are described in detail

As a kind of substrate material, plastic stretch film has a relatively short history. After printing, it serves as a package, with lightness and transparency, moisture-proof and anti-oxygen, good air tightness and toughness and folding resistance

, the surface is smooth, can protect the commodity, and can reproduce the advantages of the commodity's shape, color and so on. What are its specific features? Let's look down.

Features of plastic stretch film of various materials:

Lldpe stretch film is a colorless, odorless, odorless, translucent, non-toxic insulation material used in a large number of packaging bags. Food bags can also be made into various containers. It is idle

Sex material, therefore more difficult to print, must be processed, before printing a better effect.

Lldpe stretch film is a soft and tough film. It is clean, colorless and transparent. When it does not contain plasticizer, the film layer is always soft, resistant to freezing, stored without aging and printing

The use of oxidation polymerization of synthetic linker ink, can make printing fastness.

The strength of nylon plastic stretch film is bigger than polyethylene stretch film, tasteless, non-toxic, impervious to bacteria, oil, ester, water and most solvents, generally used

It can be printed without surface treatment in heavy, wear-resistant packaging, and cooking packaging.

Polyethylene does not have polar groups on it, it is a kind of non-polar group, which is highly imprinted in the polypropylene molecule, and every structural unit contains methyl group, which is a kind of weakly polar group

, also belongs to the polar non-high polymer basically, accordingly, they are relatively poor affinity to ink, so before printing to be able to get a satisfactory print after processing.

Nowadays, plastic packaging and plastic packaging products occupy an increasing share in the market, especially composite plastic soft packaging, which has been widely used in food, medicine and chemical industry

In other fields, food packaging accounts for the largest proportion, and plastic stretch film plays an increasingly important role
