  With the advantages of lower costs and more convenient carrying and access methods, soft packaging has developed rapidly in many fields and gradually become the mainstream of the packaging industry. Soft packaging dry composite film is a common soft packaging material, but sometimes there are some bubbles in this composite packaging film, which affects beauty. Today, the packaging takes everyone to enter the factory to explore the truth.

  1. Surface tension

  If the surface tension of the composite membrane is too small, the humidity of the adhesive on the surface will be poor, which will cause insufficient glue. In a place with less glue or no glue, bubbles will be produced. Or the surface tension of the film is uneven, which will also cause uneven glue to produce bubbles.

  In order to avoid this problem, Giant Packaging Co., Ltd. has selected a thin film with a moderate tension and uniformly uniformly, such as polyethylene film on the surface of 3.8 × 10 ~ 2) n/m. The surface tension meets the requirements to produce.

  2. High residue solvent

  If the residual solvents are too high during the production process, the solvent vaporization forms a bubble sandwiched in the film, and air bubbles will also be formed.

  The solution of Giant Packaging Co., Ltd. is as follows: 1. Control the drying temperature, control the temperature at 60-80 ° C, and set ventilation settings in the baked canal to accelerate the evaporation of the solvent. 2. Control the temperature and humidity of the production workshop. When the humidity in the air is high, the solvent volatilizes slows down. Therefore, the giant packaging controls the humidity of the workshop at 50%-60%to inhibit the residue of the solvent.

  3. Production technology

  When the composite roller is pressed, if the angle between the membrane is too large, it may be brought into the air, so that the composite film contains air bubbles, the film has high hardness, and the air bubbles are easier to enter when the thickness is large.

  In this case, you need to adjust the angle between the composite roller and the membrane, try to enter the composite roller as much as possible, and ensure the flatness of the substrate to avoid loosening or shaking.
