Cast Film Extrusion Additives | The Compound Company

Cast Film Extrusion

Cast film extrusion is an extrusion process used to create sheets or films. In this process, thermoplastic materials (such as polyethylene or polypropylene) are heated until they become molten and then forced through a slot die. The molten material is then deposited onto a cooled chill roll, which helps solidify the film quickly. Afterward, the film passes through a series of rollers that further refine its thickness and surface quality before being wound up into rolls for further processing or use. To optimize this process various additives, such as tie resins, peel compounds and masterbatches can be incorporated.

Additives

The Compound Company offers multiple Yparex and EcoForte products for the cast film extrusion process, such as tie layers and resins with adhesion to materials like polypropylene (PP), polyethylene (PE), polyamide (PA), ethylene vinyl alcohol (EVOH), PE peel compounds and mineral filled PE masterbatches. For sustainable applications we also have bio-based film grades.
