PE bag name: Polyethylene, English full name: Polyethylene,PE,PE for short. Is a non-toxic, tasteless, odorless, moisture-proof, dustproof, waterproof, antioxidant, acid, alkali resistant, plastic bag material, plastic bag production amount is the most important material, is the world recognized as the best contact food material.

PVC- polyvinyl chloride: polyvinyl chloride referred to as PVC, molecular formula is (CH2 - CH2) N, is the most important type of vinyl polymer, is the second largest plastic varieties in the world after polyethylene.

Shrinkfilm: A thermoplastic film that is stretched and oriented during production and shrinks when exposed to hot air or infrared radiation during use. After heat treatment, the film is tightly bound to the material to be packaged, the contraction force reaches the maximum in the cooling stage, and can be preserved for a long time.

LDPE-- Low Density Polyethylene: LDPE for short is the largest amount of plastic packaging and printing industry in various countries. Specific gravity is 0.92 ~ 0.93, can float in water. Low crystallinity (60%), in the pressure of 1000 ~ 3000kg/C square meters of bulk polymerization, so it is also called high pressure polyethylene. At 23 degrees Celsius, the density is about 0.92. Suitable for food packaging, fiber products packaging, daily chemical products packaging.

HDPE-- High density polyethylene: HDPE for short. With low pressure polymerization, it is also called low pressure polyethylene. It is milky white and the surface gloss is poor. Film processing can be blown molding method and T - die extrusion process. Heat resistance, cooking resistance, cold resistance and freezing resistance, moistureproof, gas proof, isolation performance is good, and not easy to break, the strength of LDPE twice. Easy to open.

BOPP-- Biaxial tensile polypropylene film: Biaxial tensile polypropylene film, also known as biaxial tensile polypropylene film, abbreviation code BOPP, its characteristics are tensile molecular orientation, mechanical strength, folding strength, gas density, moisture-proof barrier is better than ordinary plastic film. In terms of unit area and cellophane, the unit price is lower than cellophane. Due to the good transparency of this film, the color reproduction after printing is particularly bright and beautiful, is an important base material for plastic composite flexible packaging.

Since it is the most important material for the production of plastic bags, then do we know that PE can be used to produce those plastic bags? Or those plastic bags are made of PE. You want to know? If you want to know, read on.

The most common PE plastic bag is the portable plastic bag, as long as you go shopping inside the total without it. What else besides portable plastic bags? Flat bag, line bag, self-sealing bag, bone bag, zipper bag, square bag, vest bag, oblique hanging bag, flat hanging bag, bubble bag, anti-static bag, hook bag, etc.
