Plastic films and sheets are thin, flexible, and often transparent materials made from various types of plastic polymers. They are widely used in a multitude of industries and applications due to their versatility, durability, and cost-effectiveness. Plastic films are typically less than 0.25 millimeters thick, while plastic sheets are thicker, ranging from 0.25 to a few millimeters. These materials serve numerous purposes, such as packaging, protection, insulation, decoration, and more. They can be manufactured through processes like extrusion, calendaring, and casting, depending on the desired properties and applications.
