What is the manufacturing process flow of medical sterilization packaging bags?

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

Step 1: Printing

According to the customer's requirements, the imported French dialysis paper or high-quality Chinese dialysis paper shall be used, and the customer's requirements for layout design, the blank dialysis paper shall be printed.

Step 2: Composite

The raw materials of high-quality film are used for compounding through the fourth generation CPP/PET independently developed

Step 3: Slitting

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

Step 4: bag making

In a 100,000 level clean workshop, a bag making machine is used to make composite bags along the gluing place with dialysis paper and composite film at a temperature of 130 ℃～ 200 ℃ and a speed of 60 m ～ 100/min, and then the three edges are overlapped for hot melting and pressing to obtain medical packaging bags and form medical sterilization packaging bags.

The medical sterilization packaging bag adopts the microwave heat sealing method, which makes the edge sealing have high tensile strength and good uniformity. At the same time, the dialysis paper and composite film imported from France are used to avoid the problem of bag bursting during the use and sterilization process. The edge sealing is transparent. Before use, it can directly judge whether there is a false edge sealing on the whole, thus realizing the visual judgment of key indicators of the product before use.
