Film Extrusion
Keeping in mind the sensitive requirement of a Film Extrusion Processor Perfect Colourants and Plastic Pvt. Ltd. Masterbatches have salient Features.
Production of cast film is a continuous process where a thermoplastic material is extruded from a slot die onto a chill roll, quenched, and wound. The resulting film has machine direction orientation compared to a somewhat limited bidirectional orientation achieved in blown film processing. Commodity plastics are suitable for most applications and account for 90% of all thermoplastic use. They are readily available, easy to process, and the least expensive plastic for extruded products. Examples of commodity plastics include polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC).
The extrusion process can be done with the material hot or cold. Commonly extruded materials include metals, polymers, ceramics, concrete, modelling clay, and foodstuffs. The products of extrusion are generally called "extrudates".
