The packing bag of plastic bags is to point to by merchants to provide customers with. Plastic bags because of its low price was welcomed by merchants. But it's not dissolve characteristics, make it become the number one enemy of environmental protection. Plastic bags according to the raw material classification can be divided into the following categories:
(1) high pressure polyethylene plastic bags, (2) low pressure polyethylene plastic bags, polypropylene plastic bags, (3) (4) PVC plastic bags.
 
According to the shape classification:
(1) the vest bag, (2) straight bag, (3) the sealing bag, (4) strip bag, special-shaped bag (5).
 
Plastic bag production process:
Plastic bags are usually polyethylene, made by blow molding process can be divided into two kinds of high density polyethylene and low density polyethylene. First of all, to have a small film blowing machine will heating molten polyethylene plastic plasticizing made film blowing tube materials; Next to have bag making machine or plastic welder, synthesize cutting tube hot plastic bags.
Enterprise in the production of plastic bags, use what kind of raw materials as the dyeing was more suitable, do garbage bags Coloring mother good or toner, aimed at this problem, we have done the analysis:
 
First of all we have to understand toner, toner species is undoubtedly a, like you often see milk powder, a variety of color, of course, the artificial toning configuration, can according to customer required to configure the color toner, disadvantage is: should not be safekeeping, need to seal the bag packing, easily by the wind, he can make it everywhere. The toner is also easy to damp shoulds not be too long, easy to cause personnel in the manufacturing process of environmental pollution. Loss is caused economic losses.
 
Masterbatch, that are made by the carrier resin and pigment, the carrier of masterbatch can be varied, such as universal: PE, special: ABS special black mother, its shape is particle, as we often saw doug oval elliptical, its color can also be customized according to customer requirements, such as Jin Zhen: black masterbatch, the black masterbatch used: high carbon black pigment, and import carbon black, carbon concentration is extremely high, product stability is good, black masterbatch through environmental certification. In the process of processing plastic bags, process is very simple, just when blown film in accordance with the requirements for the product in a certain proportion of masterbatch, which can fully plastic dyeing, and can effectively improve the quality of the plastic bags, such as heat resistance, weather resistance, anti aging effect and so on.
