Small plastic bags may also damage the image of your brand. Now give you a few tips: 1.

If the color is uneven, there is a large color difference or turbidity in the part, you should be careful, it may not be made of pure raw materials. 2.
Odor method, normal plastic bags will not have any odor. If the product you get has odor and odor, it also means that there is a bad filler in it, it may have a bad impact on your products, especially food bags, with especially serious consequences.
