Blistering is a thermoforming process. The principle is to soften the film and then use a vacuum to allow it to adhere to the mold.

There are several criteria for judging the quality of plastics: From the surface of plastics, if there are no scratches or ripples, the overall crystal clearness is a good quality plastic box. In addition to the blister surface, it is also possible to judge from the appearance of the blister: to blister every angle, whether the lines are smooth, whether the edges and corners are clear, and whether some small places are absorbed in place. If you do it, you can basically classify it as a qualified plastic product.

Blister is a kind of packaging because it is categorized from the outside. A wide variety of plastics. A plastic blister can sometimes achieve very good results, the overall is very transparent and clear, but some blister can not do this effect. The same high-speed machine, the same mechanical operator, the reason for this reason is generally a big difference between the two plastic structures. Some plastic blister is because of the difference between the top and the bottom, some because of the hole to sink or the position is too small. For many reasons, the machine operator can only make a compromise. Four-sided drop is not big, several sides of the flat structure of the plastic is the best to do, because the adjustment of the plastic machine, whether it is the temperature setting, or the time setting of the baking sheet, and the size of the vacuum does not require precision Cooperation can meet the requirements of customers. However, the peculiarly complicated plastic box can not be easily debugged. The debugging of the whole machine must achieve a seamless realm in order to produce high-quality plastic products.

The debugging of plastic machinery is a parameter that has no uniform standard. Because of the difference in machinery, due to the different weather, due to the very different reasons of the material, it is not as accurate as the parameters in the mathematical formula. This completely relies on the experience level of high-speed machine debugging personnel, familiarity with the entire machine, control of the material, after many times of debugging and correction, and finally can produce satisfactory plastic products.
