With the development of the times, blister packaging is more and more used in all walks of life, and customer satisfaction is the power of blister packaging plant, committed to custom-made all kinds of blister boxes. Generally speaking, the glossiness of the blister packaging box refers to the specular reflection degree of the surface of the packaging box, which is indicated by the percentage. Besides specular reflection, there is diffuse reflection on the surface of packing box, which makes the glossiness of packing box decrease. The higher the glossiness of the packaging box, the more the surface can reflect the light like a mirror, and the more bright the appearance characteristics can be displayed. Blister packaging is a general term that uses blister technology to produce plastic products and uses corresponding equipment to package the products. How can the blister packaging factory solve the problem that the product surface produced by the blister packaging has pockmarks?

Cause analysis:

1. The particle size of glue is large, and the use of thin PVC is easy to produce pockmarks. The characteristics of such pockmarks are uniform dispersion; Dongguan Blister Factory

2. When the curing agent is used, the curing agent is not completely dispersed;

3. The surface of the board is not cleaned, or after spraying glue, the dust in the workshop is large, and the pits are not evenly distributed, and the sizes are different

4. The viscosity of glue is too large and the dispersion is uneven;

5. The viscosity of the glue is too small or the solid content is low, which causes the board to bristle. Such pockmarks generally appear at the corners of the grooves, forming blocks;

6. The air pressure of the spray gun is not enough and the atomization is not good;

7. The glue is not filtered.

So what kind of solution does the blister packaging factory have?

General solutions:

1. Choose glue with small particle size;

2. When the curing agent is added, the mixing time is prolonged so that the curing agent can be completely dispersed;

3. Before glue spraying, the surface of the plate shall be cleaned and the glue spraying workshop shall be separated separately;

4. Choose the glue with appropriate viscosity or high solid content; 5. After the glue is dry, polish it with fine sandpaper; 6. Increase the vacuum degree and adjust the atomization effect; 7. Use the filter screen to filter.
