In Thermoforming factories, vacuum thermoforming is widely recognized in advertising signs and commerce. An important factor is that some blister materials have the same transparent properties as glass materials. Products can be better displayed, enhancing their image and grade. However, during the production and thermoforming process, many factors affect this transparency. How to improve and prevent it?

There are several ways to improve the transparency of blister packaging products: reduce crystallinity, control the purity of plastic production, increase the refractive index and reduce birefringence.
Thermoformed shell, ABS thermoforming After adding nucleating agents, the light transmittance of transparent resin is improved, and small molecules that promote crystallization have the effect of crystal nucleation;
Biaxial stretching improves the transparency of plastics, which can destroy the crystal particles of the product, making the crystal size smaller and achieving the purpose of improving light transmittance;

Thermoforming Improving the transparency of plastics through blending means adding other resins to transparent resins to improve transparency.
In addition to choosing transparent and translucent materials to improve the transparency of blister packaging products, attention must also be paid to product quality during blister molding, printing, etc., to ensure that the blister material is not affected by the blister material. The processing environment during processing (such as temperature, humidity, etc.) and reduced the transparency of the data.

Secondly, in the manufacturing of blister molds, the surface finish and smoothness of the mold will also affect the transparency. Unless it is impossible to demold, Teflon should not be sprayed on blister molds used for transparent materials. There are also blister aluminum molds used for blister processing. Aluminum molds can easily perform appearance thermoforming, and can also control the mold temperature well. Television shell thermoforming and medical equipment thermoformed shells are also used.
