**What is cast film?
Cast film is a type of plastic film that is created using a process called cast extrusion. In this process, melted plastic is extruded through a slot die onto a chilled drum or polished roller. As the plastic cools and solidifies on the drum or roller, it forms a thin, flat film.
Cast film is different from other types of plastic film, such as blown film or oriented film, because it is produced in a continuous process and does not require stretching or orientation to achieve its final properties. This makes cast film an especially versatile and cost-effective material for a wide range of applications.
**What is cast film used for?
Cast film has many different uses across a variety of industries. Here are just a few of the most common applications:
**Packaging
One of the primary uses of cast film is in packaging. Cast film is a popular choice for wrapping products because it is strong, flexible, and can be made in a wide range of thicknesses and colors.
Cast film is used to wrap everything from food products to industrial equipment. It is especially popular for products that need to be sealed or protected from moisture, dust, or other environmental factors.
