Polyethylene foam cotton is a non crosslinked closed cell structure, also known as EPE pearl cotton, which is a new type of packaging materials. It is composed of many independent bubbles generated by the physical foaming of LDPE. The invention overcomes the defects of general foam adhesive, such as fragility, deformation and poor recovery. It has advantages such as waterproof and moisture-proof, shockproof, soundproof, thermal insulation, good plasticity, strong resistance, recyclability, strong impact resistance, and good chemical resistance. It is an ambitious alternative to traditional packaging materials.
However, during the stamping and cutting process, the forming is generally not good.
There are burrs on the cross-section:
1. Advocate the use of 0.3 thick blades for automatic cutting and winding.

2. The board's own data issues, the use of retrieved data, and unqualified data.

Stamping has curvature, and thicker materials are more noticeable:
1. The information of the mold is good, the quality is reliable, and the manufacturer needs to be reliable.
2. The blade should be made into finer serrations to facilitate contact at the completion point and to smoothly complete the cutting action of the material
3. When pressing and turning on the machine, ensure that the second punching function is good.
Generally, select reliable manufacturers for cutting machines and accessories.
EPE pearl cotton foam material is a new type of packing material. Its superior characteristics are increasingly recognized by people, so its use will continue to expand and innovate. Especially in packaging and other industrial materials, it has better functions, lower costs, higher levels, more beautiful appearances, and better functions than traditional materials. Other, it is more widely used for packaging materials of agricultural and sideline products. At the same time, EPE pearl cotton foam sheets can also be further processed. Just prepare a pearl cotton laminating machine and a laminating machine. The surface of the EPE board is covered with HDPE film, aluminum coating film, plastic coated paper, plastic coated cloth, etc. The coated EPE board can not only improve mechanical strength, but also improve stability, print various pictures and characters, and expand product promotion. Moreover, the composite sheet can be widely used in the fabric of boxes, life jackets, thermal insulation materials, moisture-proof curtains, etc., with economic benefits multiplied.
