Plastic bags is defined by the business to provide customers with bags. Plastic bags for its low prices by businesses welcome. But its non-solubility characteristics, making it the number one enemy of environmental protection. Plastic classification according to raw materials can be divided into the following categories:
Polyethylene bags are generally manufactured by the blow molding process can be divided into high-density polyethylene and low density polyethylene two kinds. First, there must be a small film blowing machine,
The heated molten polyethylene plastic blow-molded plastics film tube materials; secondly have a bag or heat sealing machine, the hot synthetic plastic tube material cutting.
Then the business in the production of plastic bags, which use raw materials more suitable as dyeing it, making good use of garbage bags or toner masterbatch good for this problem, let's do the next analysis:
First, we have to understand the toner, the type of toner is undoubtedly the only one, as we are often seen as milk, of course, a variety of colors, artificial color configuration is made according to the needs of customers can configure its toner color the disadvantage is: not custody, need to be sealed in bags, not easy to be the wind, but also confused everywhere. It should not stay wet toner is also easy, easy process causing environmental pollution. The loss of as many as resulting in economic losses.
Masterbatch, pigment is added to a carrier made of a resin,masterbatchcarrier may be varied, such as general-purpose: PE, special type: ABS special black mother, particle shape, like we often see Peas as oval to elliptical, its color can also be customized according to customer demand for black masterbatch, black masterbatch use: extremely high pigment carbon black, as well as imports of carbon black, carbon black concentration, product stability, black masterbatch through environmental certification. In the course of processing a plastic bag, the process is very simple, just follow the product requirements when blown into a certain proportion of masterbatch, plastic bags can be completely stained, and can effectively improve the quality of plastic bags, such as heat resistance, weatherability resistance, anti-aging and other effects.
