The reason and improvement ways of water ripples in blister packaging
Reason:
1. The temperature of the blister packaging mold is too high or too low, if the temperature of the mold is too high, the plastic sheet will soften prematurely, causing water ripples; If the temperature of the mold is too low, the plastic sheet cannot be completely softened, and water ripples will also occur.
2. The suction volume of the blister machine is insufficient: if the suction amount is insufficient, the plastic sheet cannot be completely adsorbed on the mold, and water ripples will also be generated.
3. Quality problems of plastic sheets: If the quality of plastic sheets is not good, such as uneven thickness and impure material, it will also lead to water ripples in blistering
Ways to improve:
1. The blister packaging mold is polished to ensure that the mold surface is smooth, which can effectively avoid water lines in the blister packaging.
2. Adjust the blister equipment so that its suction power is even.
3. Choose a blister material with good quality and uniform thickness.
4. Strictly control the heating temperature and time to avoid deformation of blister materials.
5. By changing the processing technology of blister materials, such as changing the preheating temperature and preheating time of blister materials, or changing the cooling method and cooling time of blister materials, water lines in blister packaging can also be effectively avoided.
