Paper-plastic packaging materials are suitable for ethylene oxide sterilization, pressure steam sterilization and low temperature steam formaldehyde sterilization. The useful period of storage of sterilized articles is affected by various factors such as the quality of the packaging materials, the tightness of closure, storage conditions, shipping methods, quality of sterilization, and number of contacts.
The difference between paper-plastic packaging materials and traditional cotton fabrics is as follows:
1. The paper-plastic packaging material is composed of a special material composite film and has a bacterial barrier function. Therefore, the storage time and the antibacterial function are good; the sterilization of bacteria cultivation monitoring, pyrogen monitoring, chemical indicator card monitoring, etc. of various sterilization articles have met the requirements.
Traditional cotton packaging materials have many problems, such as short retention periods. The sterilization package is packaged in a paper-plastic composite packaging material, and the sterilization effect on the packaged product is long.
2. The paper-plastic packaging material can make the sterilized gas safely soak, and eliminate the cold air in the bag to reach the thorough sterilization effect. The drainage of the paper does not form the formation of condensed water after steam sterilization of the instrument; in the sterilization process of high temperature damp heat, the paper has good resistance; while the traditional cotton package is steam sterilized to form a wet bag.
3. Useful period. The paper-plastic packaging material has a strong resistance to bacteria, and the useful period is 6 months, which saves manpower, material resources and financial resources, and reduces the number of sterilizations of the clinical standing sterilization package.
The ideal packaging material needs to have an effective bacteriostatic effect to ensure that the sterile machine is free from external bacterial contamination for a long time: at the same time, the packaging material is required to have permeability to the sterilization factor, and does not affect the sterilization factor to the bacteria. The killing function of microorganisms. Conventional cotton cloth is used as a sterilization packaging material, although it can be repeatedly cleaned, ironed, etc., but the packaging material fails to block bacteria. The packaging sterilization package in the paper-plastic composite packaging material greatly prolongs the validity period of the aseptic package and has a great effect on the sterilization of the product.
