What should be paid attention to when choosing food packaging bags?

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. So what problems should we pay attention to when choosing food packaging bags? 1. The outer packaging of plastic packaging bags for food must have Chinese logos, marked with the name of the factory, the address of the factory, and the name of the product, and marked in an obvious place.“for food”typeface. Products are accompanied by a product inspection certificate after leaving the factory. 2. The plastic packaging bags for food are odorless and odorless when leaving the factory, and plastic packaging bags with special odor cannot be used for food packaging. 3. Colored plastic packaging bags (such as dark red or black currently on the market) cannot be used for food packaging. Because such plastic bags are often made of recycled plastic. 4. Try to use materials that are not coated or coated. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of materials with plating are used. This not only brings difficulties to the recycling and reuse of materials after the products are scrapped, but most of the coatings themselves are toxic. If people eat these packaged foods, it will cause great harm to people's bodies. In addition, the coating and plating process also brings great pollution to the environment. For example, the paint volatilizes toxic solvent gas, and the waste liquid and waste residue pollution containing heavy metals such as chromium are generated during electroplating. Therefore, packaging materials that are not coated or plated should be selected as far as possible. 5. Due to the non-degradable characteristics of food plastic packaging bags, it will cause environmental pollution. Therefore, when purchasing food, it is best to use green packaging materials. Paper is currently the most widely used green packaging material. Therefore, it is best to choose original paper packaging when purchasing food, and biodegradable plastics are also acceptable. In the 21st century, with the improvement of people's living standards, in addition to the improvement of the quality requirements of the products themselves, the requirements for the packaging of the products are also getting higher and higher. . In today's pursuit of green, green packaging should be promoted. In order to adapt to this green environmental protection storm, a profound revolution is taking place in my country's packaging industry in terms of design concept, material selection, production process, product performance, waste disposal and other aspects.
