Өнөөдөр, let’s delve into the intricacies and recent innovations of plastic film manufacturing, highlighting its significance and the impact it has on our daily lives.
The Basics of Plastic Film Manufacturing
Plastic films are thin, flexible sheets made from various polymers such as polyethylene (PE), полиппопилен (PP), полот (PET), болон польвинилл хлорид (Татах PSV). The manufacturing process typically begins with the extrusion of molten plastic resin through a die, which shapes the material into a continuous flat sheet. This sheet is then cooled and stretched to achieve the desired thickness, хүч чадал, and clarity.
One of the key steps in plastic film manufacturing is orientation. Oriented films, such as biaxially oriented polypropylene (Боп дугуй) and biaxially oriented polyethylene terephthalate (Бопет), undergo stretching in both the machine direction and the transverse direction. This process enhances the film’s mechanical properties, making it stronger, stiffer, and more tear-resistant.
