It is suitable for product labels with high performance such as water, oil and chemical resistance. Hanyuan Printing often applies this material to cosmetics, shampoos, washing and other daily chemica

Polyethylene has excellent chemical stability and is resistant to various chemical substances such as hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, pota

Polyethylene is a white waxy translucent material, flexible and flexible, lighter than water, non-toxic, and has excellent dielectric properties. It is flammable and continues to burn after leaving th

Polyethylene is easy to be photo-oxidized, thermally oxidized, decomposed by ozone, and easily degraded under the action of ultraviolet rays. Carbon black has excellent light shielding effect on polye

Under the action of the atmosphere, sunlight and oxygen, polyethylene will age, discolor, crack, become brittle or powder, and lose its mechanical properties. At the molding temperature, due to oxidat

Polyethylene has good chemical stability and is resistant to dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, aceti

Polyethylene is a typical thermoplastic, which is odorless, tasteless, non-toxic, flammable white powder. The molded PE resins are all extruded and granulated waxy granules with milky white appearance

PE molecules have a certain degree of branching. LDPE has a high degree of branching. Contains 15^-25 methyl side chains and a small amount of butyl side chains per 1000 carbon atoms, because the side

The molecule of polyethylene is a long-chain linear structure or branched structure, which is a typical crystalline polymer. In the solid state, the crystalline part coexists with the amorphous form.

Polymerization pressure size: high pressure, medium pressure, low pressure; polymerization implementation method: slurry method, solution method, gas phase method; product density size: high density,

Polyethylene materials are difficult to print (unless bulk modification or surface modification is performed), so they are mostly colorless or light-colored products. Of course, due to its good enviro

LLDPE applications have penetrated into almost all LDPE markets. At this stage, LLDPE and HDPE are in the growth stage of the life cycle; LDPE gradually entered the mature stage of development at the
