2.Usage: caco3 filler for plastic bags It can be used to make PE heavy bags,PE liquid packaging film,sanitary products bags,agricultural film,PE handbags,inside bags,high quality vest PE bags,PE garbage bag. The film which add EC31C can compound with BOPP,BOPA and BOPET, have no influence on compound strength and heat-sealing strength.

3.Recommended Addition Ratio: caco3 filler for plastic bags

The addition rate is about 15%~25%.

1) In multi-layer extrusion film: we suggest to add 15%~20% in core layer;

2) under gloss demand, we suggest to add within 5% in surface layer and inside layer.

Optimal addition rate will be confirmed by trials.
