Problems solved by technology

[0002] At present, the existing four-sided PVC production in the market is usually carried out by coating process, which cannot be produced by calendering, which may easily cause problems such as product elongation and peeling strength instability. Now, through PVC and plastic paste, high elongation base The cloth is integrally formed after being pasted and pressed by an L-shaped embossing machine, so that the PVC product has excellent elongation and high peel strength to meet the needs of engineering locomotive seat molding
