Now there is a saying that the quality of PE flat pocket is related to its color. Is that right? Next, PE flat pocket manufacturers will answer for us.

一般而言，有颜色的平口袋大都使用了废旧塑料的回收料，是不能用来装食品的，比如，一些菜市场用来装鱼、虾等水产品或肉类的黑色塑料袋，原本是用来装垃圾的，消费者应避免使用，对于这种塑料袋，塑料袋厂家往往会用深颜色的色母混到一起去吹膜生产，就比如我们上面提到的黑色塑料袋就是用很差的再生料制作而成，这种材料制作出来的塑料往往外表会有很明显的杂质，所以一些厂家为了掩盖会特地采用深颜色的色母为其染色，使其难以辨认。

Generally speaking, the colored flat bags mostly use the recycled materials of waste plastics, which can't be used to hold food. For example, the black plastic bags used to hold fish, shrimp and other aquatic products or meat in some vegetable markets were originally used to hold garbage, so consumers should avoid using them. For this kind of plastic bags, plastic bag manufacturers often mix the dark color masterbatch to blow the film together, For example, the black plastic bag we mentioned above is made of poor recycled material. The plastic made of this material often has obvious impurities on the surface, so some manufacturers specially use dark color masterbatch to dye it, making it difficult to identify.
