[0002] Pearl cotton film, also known as EPE pearl cotton film bag, is a packaging material made of pearl cotton (EPE) material. Since pure pearl cotton material is easy to break, a layer of PE film is covered on its surface to increase its tensile and tear resistance, thereby improving the function of protecting the product.

[0053] It needs to be explained that the coated pearl cotton passes from under the limit shaft 84 and above the lower pressure shaft 1 82 and the lower pressure shaft 2 83. Through the joint action of the counterweight frame 62 and the adjusting spring 63, the spacing pressure wheel 65 squeezes the coated pearl cotton, and the spacing groove 651 cooperates with the surface of the lower pressure shaft 1 82 to apply uniformly distributed strip-shaped over-indentation marks to the surface of the coated pearl cotton, and the adjusting pressure rod 64 in the pressing component three 7 simultaneously contacts the surface of the limit shaft 84 and the lower pressure shaft 2 83 to fully squeeze the coated pearl cotton, so that the surface of the coated pearl cotton remains flat.
