Generally speaking, the thick and straight rib is a good-quality hollow board, and the thin rib that will bend when pressed indicates that the board is of poor quality.

Therefore, more and more manufacturers are now choosing to co-extruded the UV protection layer (UV layer) hollow board. Many manufacturers now claim that their products are co-extruded with a UV layer. The UV layer and the anti-fog droplet layer can self-discriminate ultraviolet ray is a key factor that causes the board to age. But whether the UV layer can really play a role can not be investigated by consumers at all. The UV layer of a good plastic hollow board cannot be measured only by the thickness, but also depends on the uniformity of its co-extrusion. It is necessary to choose a hollow board with a UV layer thickness and good uniformity. In view of the phenomenon that some UV materials are not added in the market but pretend to be co-extruded UV layer, hollow boards.

Corrugated Plastic Partitions Wholesalers introduces Corrugated Plastic Container has black spots and crystal spots, indicating that it contains impurities, mainly to see if there are impurities in the hollow board. The more impurity content, the more old material content is indicated. A good plastic hollow board must be clean and translucent. The quality of the materials used can also be judged by examining the fluidity of the hollow plate melt. Due to the long molecular chain of carbonate resin, its molecular structure will be destroyed when repeatedly melted at high temperatures, and the macromolecules will be degraded into small molecules. The old material needs to be re-melted at high temperatures, and its molecular chain will be broken, thereby increasing the fluidity. Therefore, in theory, the better the fluidity of the material in the molten state, the worse it's quality. Although this method is easy to understand in theory, it is still difficult to operate. Users who do not have the testing conditions can send the hollow board materials to professional institutions for testing.

Through the above introduction, Corrugated Plastic Bin Wholesalers hopes that you can simply refer to the content of this article in future use.
