Plastic Strip
Plastic strips are manufactured from channels and profiles that are slit or cut into long, narrow pieces that are used in industrial settings. These strips are either flexible or rigid, and used for different applications based on this factor. Flexible strips are mainly used as door curtains, while rigid plastic strips are made into a wider variety of products, such as trim, tracking and siding. Industrial manufacturing facilities and construction companies use plastic strips regularly. Flexible plastic strips may come in many different colors, but they are usually opaque or transparent, while rigid strips come in virtually any color and are made in standard sizes or fit to custom dimensions.
The main application for plastic strips is as flexible door curtains made of vinyl. They serve as industrial barriers and save energy, improve worker comfort and safety, and protect equipment. They are found in loading docks, interior plant doorways, freezers and personnel doors. Rigid plastic strips are generally made of PVC and have high temperature and UV ray resistance. Every plastic strip is manufactured by the extrusion process. During extrusion, thermoplastic plastic resin pellets are fed through a hopper into a screw conveyer, which sears and pushes the raw plastic along and heats it to molten form. The melted plastic is pushed through a flat die and stretched by grips into sheets which are then cooled. The strips are then cut to size in a post-forming process, rolled up and shipped.
