National standard for food packaging materials
The environmentally-friendly carton packaging material is made of waste newspapers and waste paper products, which are pulped and blended into a certain concentration of pulp (also directly using raw pulp such as wood pulp and mash), which is vacuum-adsorbed and molded. After drying and shaping to make inner packaging products of different types and uses, this article will introduce you to the national standards for food packaging materials. The non-woven fabric is made of rayon, melt-blown and spunbond. It has the characteristics of non-toxic, environmentally friendly, high-efficiency isolation, strong filtration, high toughness, acid and alkali resistance, breathable and permeable, and slight surface fiber flocculation. New high performance sterilization packaging materials. 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 sterilization 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. From the detection indicators, the new standard requires testing according to the actual conditions of use, and the selection of food simulant, test time and temperature, etc., so that the test can scientifically and reasonably reflect the safety of the product in actual use. Sex, this requires companies to master the raw materials and conditions of use of their products. In addition, the physical and chemical indicators of some products are also greatly tightened, such as the total migration of rubber acid and oily mimics is 40 times more stringent than the old standard.
