Paper plastic bags are generally composed of two sides, one side is paper that passes through and expels sterilization factors, and the other side is a transparent composite film (plastic film) that cannot penetrate liquids, air, and gases. The transparent composite film consists of at least two layers (polypropylene inner layer and polyester outer layer). The exchange of air disinfection factors takes place on one side. Due to this material, it also has good microbial barrier function, and the plastic surface is visible to the items in the packaging, so the packaging items are clear at a glance and have good impermeability. The following are the precautions for using paper plastic bags:


1. When using a paper plastic bag packaging and sealing machine, pay attention to checking whether the sealing date is accurate, and pay attention to the effectiveness of the date after the item is sealed. When the handwriting becomes lighter, the printer ink level should be increased in a timely manner.

2. When packaging, check the cleanliness and dryness of the packaged items. During the high-pressure steam sterilization process, the cleaning and drying of the instrument are incomplete, and residual oil and water can easily wet the paper and cause wet packaging.

3. Use silicone or rubber tubing to protect sharp instrument components, such as sharp scissors, to prevent paper and plastic packaging from being punctured, leading to sterilization failure.

4. Paper plastic bags need to be properly cut to remove air, disinfect penetration, and dry. Discharging unfavorable air will become an obstacle to heat and moisture, so exhaust as much air as possible before sealing. In addition, the packaging bag should not be too full. During sterilization or processing, stretching the paper plastic packaging bag may cause paper tearing or seal rupture; In addition, the equipment is packed with packaging bags, which do not have a certain amount of space inside, which is not conducive to the penetration and circulation of steam. Steam can easily accumulate on the plastic surface of the packaging bag, making it difficult to evaporate and easily wetting the bag. When instruments with concave surfaces such as bowls, cups, and bends are packed in paper plastic packaging bags, the concave surface should face the paper surface, which is conducive to steam penetration and ensures sterilization quality, as the plastic surface does not penetrate steam.

5. When using paper plastic materials for double packaging, pay attention to selecting the appropriate size order and consistency in the opening direction. Do not fold the paper plastic bag inside as it will interfere with the discharge of air and the penetration of the sterilization medium. Stick plastic paper stickers to ensure the penetration, drying, and visibility of the contents of the sterilization medium.

7. Paper plastic bags: When writing information on paper plastic materials, pay attention to using a flexible pen. The flexible pen can only be written on areas outside the plastic surface and filling area. Do not write on paper to prevent ink penetration and affect the sterilization effect.

8. Paper and plastic packaging items should be handled with care, especially heavy instrument bags or large bags. Do not drag, squeeze, transport, throw or other actions to prevent damage to the packaging bag. When sealing high-temperature and low-temperature items, they should be classified to avoid confusion, otherwise they may be damaged due to incorrect basket loading.

9. Paper plastic bags: When paper plastic packaging bags are placed in water, they need to be packaged in stainless steel baskets. They should be placed vertically. Paper to paper and plastic to plastic should be placed between different packaging bags. There should be a gap (approximately 2.5cm apart) between the two bags, and it should not be too crowded to facilitate the penetration of sterilization factors; It can also prevent moisture from staying on the plastic surface, causing wet bags.
