Plastic films are a versatile and widely used material in many industries. They can be produced using a variety of methods, including blown film, cast film, coextrusion, lamination, and composition. Each of these processes involves melting small pieces of plastic into resin, molding them into specific shapes, and cooling them to create the desired product. Blown film is a popular method for creating plastic films, as it involves introducing air into a tube-shaped bubble to expand and solidify the molten mass.
CNC machining is another subtractive process that is used to create plastic parts. 3D printing is also becoming increasingly popular for creating plastic parts and prototypes. Regardless of the method used, it is important to ensure that the plastic film meets the customer's needs and specifications. This guide will provide an overview of the different types of plastic film manufacturing processes and their applications.
