The sanitary safety problem of ceramic packaging materials used in food packaging mainly refers to the dissolution of heavy metal elements such as lead or cadmium in the glaze layer of glazed ceramics, which is harmful to human health. When these containers are used to hold acidic foods (vinegar, juice) and wine, these substances are easily dissolved and migrated into foods, and even cause poisoning. This article will introduce you to the hygiene 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.
Similar applications include seafood packaging that requires cold chain cryogenic transport, such as the packaging of common shrimp, crab or shellfish products, which are generally sharp-edged and therefore require higher physical strength and mechanical toughness of the packaging material. In this case, INNATE® precision packaging resin is a more suitable product.
