Hello, Welcome to Weifang Sunraise Plastic Products Co., Ltd. website!

So what kind of plastic bag can be used to hold food? When using plastic packaging bags, you can use high-pressure polyethylene raw materials, which are made of materials that are safe and do not contain chemicals harmful to the human body. Therefore, you can use packaging bags to load food. Such bags can also be used for cosmetics and clothing. In the process of using plastic bags, if you can clearly classify and pay attention to the selection of bags, you can achieve the desired application effect.

     When choosing a plastic bag, there are actually many problems to be aware of. Some bags are made of polyvinyl chloride film. This bag does not add any pigment during production, but some chemical reagents are used during the production. Therefore, this kind of packaging bag can not be used for food, but can only be used for loading garbage or ordinary items. In order to ensure safer and more convenient when using the packaging bag, the above problems should be paid attention to when selecting the packaging bag.
