The choice of biodegradable food bags should be marked in Chinese, indicating the name of the factory, address and product name, and clearly marking the word "food". After the product leaves the factory, the product inspection certificate is attached. Degradable food bags are odorless and tasteless when they leave the factory. Plastic bags with a special smell cannot be used for food packaging. Colored plastic bags cannot be used for food packaging.

Degradable food bags should be made of materials that are not coated or plated as much as possible. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of coated materials are used. This not only brings difficulties to material recovery and reuse after product end-of-life, but most of the coatings themselves are toxic. If people eat these packaged foods, it will cause great harm to the human body. In addition, the painting and electroplating process also brings great pollution to the environment. For example, the paint will volatilize toxic solvent gas, and the electroplating process will produce waste liquid and waste residue containing chromium and other heavy metals.

The important function of the so-called degradable food bags is to store food, and the packaging bags are different according to the food. As always, food packaging is important in the following ways. If it is necessary to store some cooked food, it is necessary to choose some vacuum degradable food bags. The advantage of choosing biodegradable food bags is that they can protect the hygiene of food and prevent infection by other substances. It can ensure that the food in the packaging bag is clean when eaten.

Degradable food bags are film containers that are in direct contact with food and are used to hold and protect food. They use food-grade plastic film, and generally have more than two layers of composite packaging bags, multi-layer co-extruded bags, aluminum foil bags, paper-plastic bags, etc. According to the use function of degradable food bags, there are: ordinary food, vacuum food, inflated food, steamed food, frozen food, functional food and other packaging bags. According to the packaging form, it is divided into: three-side seal, four-side seal, middle seal, back seal, stand-up pouch, zipper bag, nozzle bag, etc.

The biodegradable food bag should be flat, without scratches, scalds, air bubbles and wrinkles, and without false seals. Flatness is not only a beautiful requirement, but also related to the quality of food. Food packaging intended for high-temperature cooking or low-temperature freezing will be prone to cracking if the bag is not sealed evenly. Printed degradable food bags should use green environmental protection materials. The QS standard requires that benzene solvents that are harmful to human health cannot be detected in food packaging. However, benzene solvent is about 30% cheaper than environmentally friendly benzene-free and ketone-free solvents, and has better brightness and color fastness. Therefore, many packaging bags are printed with this material, often causing food contamination problems. The production environment of enterprises that produce degradable food bags should meet the standards to avoid contamination of degradable food bags during the bag making process.
