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 kinds and uses, this article will introduce you to the choice of 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 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. Due to the complexity of the composition of the packaging material, the precipitation of substances in the food packaging material occurs in the food, possibly due to the migration of these substances to the food, or in the food due to accidental extraction. This causes chemical migration of food packaging to have a negative impact on food. Article source address: http:// Beauty scissors can be used to trim eyebrows and nose hair.
