Plastic Strip

A reliable source for Plastic Strip information and leading Plastic Strip Companies & Manufacturers.

A plastic strip is a plastic shape made from continuous fabrication processes. There are a variety of plastic strips, and they are often placed in doorways for climate control in industries and public places. Many of the plastic strip varieties are characterized by narrowness and length.Read More…

Plastic Strip Plastic strips are plastic shapes manufactured during continuous plastic fabrication processes. The criteria for plastic strip qualification are not universal; the words strip, sheet and even channel are applied largely according to preference or opinion.

They are used as building trim, collators for nails in nail guns, furniture components, and other multiple purposes. Some rigid plastic strips can be made from multiple plastic materials, including low and high-density polystyrene, PET, polyethylene, and many other plastic materials.

The materials used to make plastic strips are chosen based on their qualities of durability, weather resistance, strength, and other relevant qualities. For example, PVC is chosen due to its resistance to UV rays. The process of manufacturing plastic strips is called extrusion. It is a fabrication process that is continuous. This makes it more suitable for the creation of plastic strips of long length. A collection of raw plastic materials are used to produce plastic strips by placing them in a hopper suspended above an extruder.

How Plastic Strips are Manufactured

Plastic strips are manufactured from the extrusion process. Plastic extrusion is a high-volume manufacturing process in which a polymer material enriched with the desired additives is melted and then formed continuously.

The raw materials are in the form of granulates. They are gravity fed into the hopper through the feed throat. They then drop on a rotating screw. An electric motor is used to provide the rotation of the screw. The screw rotation will force the plastic polymer through a heated barrel. While the plastic is conveyed through the barrel, the channel of the screw decreases, and the plastic is compressed.

The plastic is melted and reaches the end of the screw, where it is mixed and pushed through a screen pack. Finally, the melt is pushed through the die. The die forms the desired profile and shape of the final product. The extruder then exits the extruder, and it is pulled and cooled. The method of cooling depends on the profile and shape of the extrusion.

Types of Plastic Strips

The different types of plastic strips include:

Polypropylene Plastic Strips

Polypropylene plastic strips have good chemical, fatigue, and temperature resistance. However, it is difficult to form this material because of its narrow thermoforming temperature window. Webbing also can be a problem.

PP has a semi-crystalline nature, increasing the post-forming shrinkage rates. Talc is used as a filling to improve these properties.

Acrylonitrile Butadiene Styrene Strips

These are one of the most versatile and widely used plastics. ABS has a very wide forming temperature range, making it relatively easy to form. In addition, ABS strips exhibit good dimensional stability, which makes them easier to trim.

Acrylic Plastic Strips

Acrylic plastic strips are versatile products. They are easy to machine, screen print, and polish and have improved resistance to impacts.

PVC Plastic Strips

PVC plastic strips are stiff strips with good resistance to impacts. Their fabrication, welding, and thermoforming are easy, but they become brittle at low temperatures.

Applications of Plastic Strips

Plastic strips are mostly used in consumer, industrial, and commercial applications. They are used to create plastic frames or trims that function as secondary doorways or barriers. These facilitate energy efficiency and limit the loss of cold or hot air. The following is a list of the common applications and uses of plastic strips:


  • Fences
  • Edging
  • Weather-stripping
  • Post
  • Tubing
  • Pipe
  • Window frames


  • Machine trim
  • Machine protectors
  • Tracks
  • Equipment trim and protectors
  • Electrical wire covers

Benefits of Plastic Strips

  • Low maintenance
  • Cost-effective
  • Prevent 80-90% of air loss through doors
  • Enhance hygiene
  • Reduce product spoilage
  • Reduce wear and tear on switches, motors, and compressors
  • Restrict air pollutants from entering
  • Perform well in outdoor environments
  • Easy to fabricate
  • Impact-resistant
  • Strong and stiff
