For the flexible packaging industry, it is a major opportunity to challenge and expand the market. “In response to the globalization of trade, integration and the higher requirements of e-commerce for the flexible packaging industry, Dow has developed INNATE® precision packaging resin. Its main feature is that it can be used to make toughness and mechanical strength on the basis of ordinary packaging. Uplifting about twice, without sacrificing other properties, such as the rigidity of INNATE? It is not affected by the increase in toughness - this is essential. At the same time, this packaging material can also bring higher design freedom. This article will introduce you to the identification criteria for food packaging materials.
The metal materials used in current food packaging include iron, aluminum, stainless steel, and the like. The packaging material can use metal, because the metal has better ductility and is more convenient to process. The outer packaging formed by the metal has better protection for the internal food, and the metal is easy to be packaged and thus can be promoted.
However, metal is good for paper, glass and ceramics, but the price is relatively high and the packaging cost is not cheap. Moreover, the chemical nature of the metal is relatively active, it is oxidized and eroded in the air, and it is easy to chemically react with foods containing strong acidity and alkalinity, thereby causing pollution to food. Therefore, at present, although metals can be widely used and have an important position, their use is limited, and they are generally used for canned packaging.
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.
