In the past, most of manufacturers produce plastic bags with 100% resin HDPE. It costs a lot of espensive input materials. Besides that, the quality is not so good in some cases. That's why CaCO3 filler masterbatch become the most important material in making plastic products.
1 Improve the anti-heating, rigidity and tightness property.
2 Remove the surface light from plastic products, to get sub-light effect.
3 Improve the surface antifriction and antislip property of plastic products.
4 Reduce shrinkage ratio of final products to improve size stability.
5 Reduce fire heating quantity of plastic products to reduce second pollution.
6 Improve surface printing property of plastic to reduce needed electric current under surface corona process.
7 Provide breathe free to film products.
8 Improve heat-conduction property of plastic material to reduce molding period.
