Modern food packaging materials use a large number of chemical synthetic substances, which can be divided into two broad categories: known components and unknown components. These substances mainly include: monomers and other synthetic materials of synthetic materials, catalysts, solvents and suspension media, packaging materials additives (including antioxidants, antistatic agents, antifogging agents, plasticizers, heat stabilizers, nucleating agents) As well as dyes and pigments, this article will introduce you to safe food packaging materials.
An antimicrobial packaging material that has the function of reducing and inhibiting microorganisms in the food package so that it can stop growing or inactivating. We generally classify this material as mobile, regenerative, adsorbable, and immovable. At the same time, it will not have any impact on the quality of the food.
The surface of the packaging material is treated with an antistatic agent or subjected to a deep composite treatment to reduce the electrical resistance of the original material and improve the electrical conductivity, thereby achieving the purpose of eliminating static electricity. In general, the antistatic agent has a simple process, low cost, convenient production, and no special requirements on equipment, and thus occupies a certain position in actual production. This is the mainstream of the current popular, and is also the development direction of anti-static bags in the future.
The management of food packaging materials in the United States is primarily regulated by the federal regulations CFR. Part 21 of the CFR of the United States regulates the management of food and medicine, and Sections 170-186 regulate the management requirements for food packaging materials.
