What are the raw materials needed for making plastic bags?
The bags made of two materials each have their own characteristics, and are chosen according to the purpose and performance of the products. Polyethylene is petrochemical products, prices vary according to crude oil and market conditions every day, at present LDPE (high pressure polyethylene) offer at 13500 yuan. HDPE (low pressure polyethylene) at 11000 yuan up and down.
In addition, the bag color and performance requirements are not high, you can choose recycled polyethylene. Plastic can be recycled, because of the repeated use of processing, non-toxic, tasteless new plastic become cloudy, less than the original hygiene and color requirements.
