Information

Packaging film has the characteristics of puncture resistance, ultra-high strength and high performance, and is widely used. However, many customers report that the surface of the packaging film will have the following spots during use. We have followed up with the packaging film manufacturer to understand why. Found the reason.

If the viscosity of the adhesive of the packaging film is too large, the fluidity will deteriorate. It will cause uneven glue and affect the reflective properties of the aluminum coating surface and produce spots. The surface tension of the ink film is low, resulting in poor adhesive coating effect and uneven glue. Therefore, the bonding force and tightness between the ink layer and the aluminum layer will change, which reflects the effect of the aluminized layer surface regardless of strength. Form white or gray on the viewpoint. Packaging film manufacturers remind everyone that if the ink hiding power is not strong or the leveling is poor, it will cause uneven coverage. Where the covering effect is not good, the color of the aluminized layer will penetrate into the ink. The concentration of the binder is too high and the viscosity is too high. It is easy to reverse the ink to liquid, thereby changing the color of the printed layer.

1. PVC heat-shrinkable film has high strength and large elastic tension, which can tightly wrap any geometric shape commodity and avoid damage caused by strapping. It has good effects of preventing loosening, rain and dust.

2. PVC heat shrinkable film can use high-performance resin and auxiliary materials to meet the needs of different users.

3. PVC heat shrinkable film stretch packaging saves raw materials than shrink packaging, and no heat shrink packaging machine is needed to save energy.

4. The heat shrinkable film manufacturer reminds you that PVC heat shrinkable film is suitable for packaging requirements of various products. It can be made into a single-sided viscous product, reducing the noise generated during winding and reducing dust and sand during transportation.
