What is the manufacturing process of sterile paper-plastic packaging bags? Explain it to you in detail!

The manufacturing process of the sterilized paper-plastic packaging bag includes the upper film and the bottom paper, which is characterized in that a circle of water-based adhesive is coated on the back four frames of the bottom paper, and the bottom paper and the upper film are heat sealed at the position where the water-based adhesive is coated on the back of the paper to form the sterilized paper-plastic packaging bag. The manufacturing process of sterilized paper-plastic packaging bags is as follows:

*First: printing

According to customer requirements, imported dialysis paper or * quality Chinese dialysis paper is used, and blank dialysis paper is printed and typesetting design according to customer requirements.

**Step: Compound

Through the fourth generation of CPP/PET independently developed, the raw material of * quality film is used for composite.

Step 3: Cutting

Cut the printed paper and film through the installation size of the slitter.

Step 4: Bag making

In the 100000 * clean workshop, the dialysis paper and composite film are made into composite bags along the gluing part with the bag making machine at the speed of 130 ℃~200 ℃ and 60 m~100/min. After overlapping, the three sides are fused and pressed to obtain medical packaging bags, forming medical sterile packaging bags.

Sterilized paper-plastic packaging bag adopts microwave heat sealing method, which makes the sealing edge have high tensile strength and good uniformity. At the same time, dialysis paper and composite membrane imported from France are used to avoid the problem of bag explosion during use and sterilization. In addition, the edge banding is transparent, so it can intuitively judge whether there is false edge banding on the whole before use, so as to realize the intuitive judgment of key indicators before using the product.

Sterilized paper-plastic packaging bag has the environmental protection effect of non-toxic, tasteless and paper-free; Apply a circle of glue on the back of the paper, saving production costs; Because the flexographic machine is used to complete printing and gluing in reverse synchronization, the process flow is reduced and the production efficiency is improved. Our company is a professional medical device and drug packaging manufacturer integrating R&D, production and sales.
