PE (Polyethylene) filler masterbatches are additives used in the plastic packaging industry to modify the properties of polyethylene-based materials. These masterbatches typically contain a high concentration of filler materials, such as calcium carbonate, talc, or other mineral-based compounds, mixed with a carrier resin, which is also usually polyethylene.

Depending on the type of filler used, PE filler masterbatches can enhance the barrier properties of packaging materials. This includes improved moisture resistance, oxygen barrier, and UV resistance, which can extend the shelf life of products and protect them from environmental factor Incorporating filler materials can reduce the weight of packaging materials while maintaining their structural integrity. This is particularly relevant for lightweight packaging applications, such as flexible films used in shipping and retail bags.
