2 high-pressure materials ldpe and lldpe, including 1 18w2 18w and100/kw, etc. Half of the low-pressure material formula is: hdpe57% lldpe 10% filler (called calcium carbonate) 15% recycled material 15% and masterbatch 3%. If desiccants, spices and crimson materials need to be added, the proportion of HDPE is reduced from 57% to 55, and the three desiccants are 0.2% and the spices are 0.45%.

The formula of high-pressure materials is generally lldpe or ldpe, and the ratio of recycled materials is 7: 3. Generally, fillers are not needed, as the case may be.

Fillers are packed in large cartons imported from the United States in Changzhou, Jiangsu.

3 tr 13 1 this hdpe from Qatar is good, soft, and has good tensile strength when blown, and it is not easy to break the film. Generally used for blowing low-pressure materials, use with caution under high pressure.

4. Reduce the cost: control the film charging rate, properly use fillers with the consent of customers, and add appropriate recycled materials without affecting the quality.
