What is the type of bag material in the box?
In recent years, many food researchers at home and abroad have gradually focused on the edible packaging film, and developed many edible packaging films with different functions, such as soybean protein edible packaging film, chitosan edible packaging film, protein, fatty acid, starch composite edible packaging film, water-resistant protein film, edible packaging paper with soybean dregs as raw material, edible They are as follows: sex packaging container, corn protein packaging film (paper, coating material), insect film or protein coated packaging paper (or container), corn starch sodium alginate or chitosan composite packaging film (paper), bio glue coated packaging paper.
Bags in food boxes are generally made of two types of plastic film. One is made of polyethylene, polypropylene and melamine. The other is made of PVC, which is toxic by adding plasticizer during the production process. In addition, stabilizers are added to some bag products in boxes, and these stabilizers are mainly lead stearate. The lead salt in these stabilizers is easy to separate out. Once inhaled into human body, it will cause accumulated lead poisoning, thus harming the health of consumers. So pay special attention to the bag in the box.
Edible film can be eaten together with its packaged food, and has certain nutritional value. Some of it can be digested by human body, and some edible film itself has health care effect on human body. It can also be used for small amount of food packaging, monomer food packaging, direct contact with food, to prevent food contamination. In order to improve food quality and sensory properties and enhance appetite, some flavor agents, colorants and nutritional fortifiers can be added to the edible film. Moreover, the edible film can be used as food flavor agent, fermentation agent and food quality pigment micro packaging, and can effectively control the addition, release and stability of these preparations. Edible films can also be used as carriers of preservatives and antioxidants to control their diffusion rate into food interior on the surface of food, which is conducive to reducing the amount of these additives. The edible film can also be added to the internal interface of heterogeneous food to prevent food deterioration or affect food quality due to the migration of water and solute between food components. Edible film can also be used as microwave, baking, fried food packaging film. At the same time, edible membrane as a degradable membrane, if not eaten, can still be degraded by microorganisms in the environment, will not cause environmental pollution.
