Our most common transparent blister packaging materials are divided into PET materials and PVC materials. In the blister industry, all transparent materials are used in the regular material of these two materials. How to judge the quality of the transparent blister packaging? We start from the blister material and the blister mold. We have talked about blister materials before. Today, we talk about the classification of molds, molds are divided into gypsum mold, copper mold, aluminum film.
The cost of gypsum mold is the lowest, the cost of aluminum film is the most expensive, followed by copper mold; Gypsum mold is generally used to make samples for customers, which is conducive to the modification of product packaging. The price is lower, but the durability is lower. The copper mold has a layer of copper film attached on the surface, which is electroplated, so it is more durable. Generally, it is used as a mass production mold, which is also the most commonly used one. Blister products are simple in construction, curve requirements are not high can choose to use copper mold; The aluminum film has high precision, beautiful profile and Angle, and high durability. In fact, aluminum mold is the first choice for mass production and high-demand plastic molding production, compared to gypsum mold, copper mold more durable, high production efficiency and extremely low scrap rate.
Recently, many customers need too few blister packaging boxes, and the reason given by the customer service of the blister packaging manufacturer is that the quantity is too small to order materials, so I wonder, aren't the materials all transparent PVC or PET materials?
The materials of blister packaging boxes are only PVC, PET, PS and PP. However, the production process of the blister packaging box involves a problem of plate-forming, that is, how many holes to make the bulk mold and how to arrange the most appropriate. Each blister packaging box is different in size because of the different plate-forming methods, so the size of the bulk molds after plate-out will not be the same. The final material specification of the blister packaging box will be determined according to the size of the bulk mold discharged, and the material thickness required for different blister packaging boxes is different, even if the difference is 0.1mm, it is also a big gap for the materials of the blister packaging box. Therefore, it is difficult to share the materials between the blister packaging boxes, unless the two blister packaging boxes have the same length, width and height on the outside, but the internal structure is unchanged, so that they can be Shared, but this situation in the blister packaging box industry is rare.
