Blister food box packaging It is not only convenient for taking food, dust-proof, and sanitary, but also can improve the quality. It is one of the indispensable packaging products in the packaging industry. There are many types of blister box products, and the processing methods are slightly different. The blister box processing requires the manufacturer to pass the QS certification, and the material is also required to reach the food level. In order to produce better quality products, every process is inevitable.
The process of blister food box processing includes the following points:
1: The mold making and processing of blister box products shall be based on the requirements or sample specifications provided by the customer. The blister mold shall be made first. Generally, it is made of gypsum Blister packaging However, wood carving and metal carving products can also be used as molds. After the plaster mold is made, it should be allowed to dry completely or dry naturally; Secondly, according to the specific situation of the concave and convex surface of the product, use 1-2 mm drills to drill many small holes in the low concave places that do not affect the product packaging appearance. If it is a product such as a packaging box, it is also necessary to drill some small holes on the four sides, so that the plastic suction machine can draw out the air during the plastic suction production, and the mold can drill the holes; The gypsum mold must also be hardened by soaking in concentrated alum saturated solution and drying.
2: The process of blister packaging products, such as blister tray, food tray, food tray, and blister tray, is roughly the same. Mold processing of blister packaging products is a very important process. After processing, a drying process is required. The mold is loaded onto the iron plate on the upper layer of the vacuum chamber, and then the plastic sheet is loaded into the applicable size according to the size of the mold, Then put the sheet into the heating wooden cabinet to fix it, and then put the wooden cabinet and plastic sheet on the constant temperature furnace for softening treatment.
3: The softened plastic sheet and the wooden cabinet are placed in the vacuum chamber, and the suction switch is turned on to suck out the air in the vacuum chamber. After the plastic sheet is cooled, the same concave packaging or process mold as the mold is obtained.
4: Blister packaging finishing; Trimming and finishing the blister packaging products produced, such as blister tray, food tray, food tray, blister tray, are finished products, which can be sold after packaging.
