Transparent sealing strips are a type of plastic sealing strip; however, they cannot be manufactured using recycled plastics, which results in relatively poor recyclability. During production, PVC transparent sealing strips must first be processed into plastic pellets before they can be further molded into the desired sealing profiles. To begin, resin powder, lubricants, and various additives are thoroughly blended in a mixer. Once the mixture is uniform, it is fed into a pelletizing machine to produce granules. The plastic is then conveyed via a feeding system into the extruder barrel, where it is heated and plasticized. Inside the barrel, the screw performs a series of operations—shearing, compressing, and kneading—to achieve the final product.

Transparent sealing strips are a type of plastic sealing strip; however, they cannot be manufactured using recycled plastics, which results in relatively poor recyclability. When producing PVC transparent sealing strips, the raw materials must first be processed into plastic pellets before they can be further molded into the sealing strips we require.

We mix raw materials such as resin powder, oil, and additives in a mixer. Once the blend is uniform, it is fed into a plastic pelletizing machine to produce pellets. The material enters the extruder barrel via the feeding system, where it is heated and plasticized; the screw then subjects it to shearing, compression, and intensive mixing, among other processing steps. Finally, the molten material is extruded through the die of the pelletizer, forming the plastic pellets we need.

Plastic pellets are the raw material used to manufacture transparent plastic sealing strips. After the pellets are produced, they are processed by a plastic extruder and then extruded through the die to form the desired product shape. Once extruded, the products are cooled in water to yield the finished goods. Extruders for transparent plastic sealing strips cannot be used interchangeably with standard plastic extruders; this is due to differences in their plasticizing capacity, and because using them interchangeably can lead to color contamination and other issues that compromise product quality.
