The choice of plastic packaging bags need to pay attention to these 8 points!

　　Food packaging bags are closely related to our lives. With the rapid development of society, the demand for food packaging bags is increasing, and there are more and more types. What problems should we pay attention to when choosing food packaging bags?

　　1. The outer packaging of food bags for food requires Chinese signs, marked the factory name, factory address, and product name, which clearly indicates the words of food. After the product is issued, there are product inspection qualification certificates.

　　2. Food packaging bags without odor and odor when they leave the factory. Plastic packaging bags with special smells cannot be used for food packaging. 3. Colored plastic packaging bags (dark red or black, etc.) cannot be used for food packaging. Because this plastic packaging bag is usually made of recycled plastic.

　　4. Try to choose materials that are not coated or plated. In modern packaging design, in order to make the packaging more beautiful and corrosion -resistant, a large amount of materials with coating are used. This not only brings difficulties for the recycling and use of materials after the product is scrapped. Most of the coatings are toxic. People eating these packaging foods are very harmful to people's body. In addition, the coating and coating process has brought great pollution to the environment. For example, coatings volatilize toxic solvent gas, and produce heavy metal waste liquids and waste residue pollution such as chromium during electroplating. Therefore, please try to choose the packaging material without painting and coating. 5. Food packaging bags that are not easy to decompose will cause environmental pollution. It is best to choose green packaging materials when buying food. Paper is currently the most widely used green packaging material. Therefore, when buying food, it is best to choose the original paper packaging and biodegradable plastic.
