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 main products of packaging materials.
The non-woven fabric is made of rayon, melt-blown and spunbond. It has the characteristics of non-toxic environmental protection, high-efficiency isolation, strong filtration, high toughness, acid and alkali resistance, breathable water permeability, slight surface fiber flocculation and so on. 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 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.
Some food factories do not use food packaging special inks when using paper food packaging materials, and most of these non-special inks contain organic solvents such as toluene, which may cause excessive benzene solvents in foods, and benzene solvents are more toxic (in GB). The 9685 standard is not allowed to be used. If it penetrates into the skin or blood vessels, it will endanger the hematopoietic function of the human body, damage the nervous system of the human body, and even cause leukemia.
