What kind of mold should I choose for transparent blister packaging?
Usually our most common transparent blister packaging materials are divided into PET material and PVC material. In the blister industry, these two materials are used for all conventional materials of transparent materials.
Then how to judge the quality of the transparent blister packaging made, we start from blister materials and blister molds. We have talked about blister materials before. Today, we will talk about the classification of molds. The molds are divided into plaster molds, copper molds, and aluminum films.
Among them, the cost of plaster mold is the lowest, the cost of aluminum film is the most expensive, followed by copper mold; plaster mold is generally used to proof for customers, which is beneficial to the modification of product packaging. The price is lower, but the durability is lower. After a period of use, It is relatively easy to be damaged, so it is generally not necessary to make a mass production mold; a copper film is attached to the surface of the copper mold, which is plated, so it is more durable. It is generally used as a mass production mold, and it is also the most commonly used one. Plastic products with simple structure and low curve requirements can choose to use copper molds; aluminum film has high accuracy and the profile and angle of the products produced are beautiful, and the durability is very high, and the price is the first in the mold category; in fact, aluminum Molds are the first choice for high-volume and high-demand blister production. Compared with gypsum molds and copper molds, they are more durable, have high production efficiency, and have extremely low scrap rates.
