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 the advantages and disadvantages of wood packaging materials.
Green packaging is one of the major topics in the development of the global packaging industry. The development of green packaging materials is also the focus of the world. The purpose of the development of green packaging materials is to make the materials themselves return to nature, harmless to the human body, and no pollution to the ecological environment; while the processing of materials is low-carbon emissions, processable and low energy consumption. Fully in line with the above requirements of green environmental protection, it has more advantages.
Although the disposable non-woven fabric has a great barrier effect on microorganisms, it is not easy to be affected by secondary pollution. The sterilization effective time limit is 6 months, and the resistance to penetration is strong, and there is no wet bag phenomenon. It is more advantageous than other sterilized packaging materials in terms of physical properties, sterilization compatibility, sterilization quality, and storage efficiency. However, its puncture resistance is poor, it is easy to be broken as a separate packaging material, and it is most likely to cause puncture exposure when it is packaged as a sharp device, which seriously affects the quality of sterilization. Therefore, our hospital generally uses cotton cloth as the inner layer packaging and non-woven fabric as the outer layer packaging, and the effect is very good.
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.
