First of all, observe whether the surface color distribution of plastic craft storage bins is uniform and whether the color is bright. If there are spots and dim colors on the surface of the craft storage bins, it means that other things must be mixed in the raw materials, and the quality needs to be verified.

  Secondly, smell whether there is a bad smell in the craft storage bins. If it is not handled properly in production, it will lead to the generation of peculiar smell. The industry that is used to hold food needs to pay attention to.

  Finally, according to the weight of the craft storage bins to identify good or bad, the heavier the box of the same batch, the better. It should be noted that some bad merchants will add talcum powder and other substances before forming the craft storage bins to achieve the effect of weight gain, which actually reduces the toughness of the craft storage bins and shortens the service life. So we must choose regular manufacturers to buy.
