The following types of plastic bags we often use:
Polyethylene (PE), referred to as PE. It is an organic compound of polymer for ethylene. Polyethylene is the best ingredient of food in the world. Non -toxic, odorless, odorless, meet food packaging sanitary standards. Polyethylene film, light and transparent, has a general performance such as moisture -proof, antioxidant, acid resistance, alkali resistance, qi tightness, and excellent thermal sealing. It is known as the "plastic flower". It is the most important and most important material for plastic packaging.
LDPE-low-density polyethylene
Low -density polyethylene, referred to as LDPE, is the largest variety in the plastic packaging and printing industry of various countries. The gravity is 0.92 to 0.93, which can float in water. Low crystalline (60%), the ontology aggregation is performed at 1000 to 3000kg/c㎡, so it is also called high -voltage polyethylene. At 23 degrees Celsius, the density is about 0.92. The pressure extension type is poor, and it is suitable for processing into a tubular film. Suitable for food packaging, fiber product packaging, daily necessities packaging.
HDPE-High-density polyethylene
High -density polyethylene, referred to as HDPE. The density is 0.941 ~ 0.965g/cubic centimeter. It is made of low -voltage aggregation, so it is also called low -voltage ethylene. It is milky white, indicating that the gloss is poor. The processing film can be squeezed out with a blowing method and T mold. Heat resistance and steaming, cold -resistant and freezing, moisture -proof, gas -proof, and isolation performance, it is not easy to damage. The most common shopping bags and plastic vest bags in supermarkets.
PVC-Polyethylene
Polyethylene is referred to as PVC, and the molecular formula is (CH -CH) N. It is the most important category of ethylene polymer. It is currently the second largest plastic variety in the world after polyethylene. The domestic yield is ranked first in plastic. In the printing industry, polyvinyl chloride color pressure -delay film and transparent upper -light film make books, folders, tickets and other seaweed packaging and decoration.
Shrinkfilm-shrinking film
Shrinkfilm is a thermoplastic plastic film that is stretched by stretching during the production process, during use or infrared irradiation, which will shrink. After thermal treatment, the film is tightly wrapped in the packaging material. The contraction force reaches the maximum value during the cooling stage and can be stored for a long time.
BOPP-two-way stretch polypropylene film
The double -axis stretching polypropylene film, also known as a two -way stretching polypropylene film, and English abbreviation code BOPP. It is characterized by stretching molecular orientation. The mechanical strength, folding strength, gas density, and moisture resistance are better than ordinary plastic film. Compared with glass paper, the unit price is lower than glass paper. Due to the excellent transparency of this film, the color is particularly bright and beautiful after the printing, which is an important substrate for plastic composite soft packaging.
