In the modern packaging industry, Blister packaging It occupies an important position with its special advantages. Blister packaging manufacturer Through a series of fine production processes, raw materials are transformed into various practical and beautiful packaging products.

The main raw material of blister packaging is plastic sheet, commonly including PVC, PET, PP, etc. The manufacturer will select appropriate sheet materials according to customer needs and product characteristics. These sheets are usually supplied in the form of coiled materials or sheets. Before entering the production link, quality inspection is required to ensure that their thickness is uniform, free of defects, and their color is consistent. Mould is the key link of blister production. According to the design requirements of the product, the manufacturer will make corresponding molds. Mold can be divided into plaster mold, copper mold, aluminum mold, etc. Gypsum mold has low production cost and short cycle, which is suitable for small batch production; Copper mold and aluminum mold have high precision and good durability, and are suitable for mass production. In the process of mold making, it is necessary to accurately control the size and shape to ensure the quality of blister products. Place the qualified plastic sheet on the heating plate of the plastic suction machine for heating. The sheet is softened by adjusting the heating temperature and time. The heating temperature and time required for different plastic sheets will be different, and the manufacturer needs to make reasonable settings according to the characteristics of the materials. During the heating process, ensure that the sheet is heated evenly to avoid local overheating or supercooling. When the sheet is softened to a certain extent, it is moved to the top of the blister mold, and the air between the mold and the sheet is pumped by the vacuum pump to make the sheet cling to the mold surface, forming a blister product consistent with the mold shape. In this process, the control of vacuum degree is very critical. Too high or too low vacuum degree will affect the quality of products. At the same time, the blistering time also needs to be adjusted reasonably according to the thickness and complexity of the product. After the completion of blistering, the product needs to be cooled and shaped. Air cooling or water cooling is usually used to cool the product rapidly and keep the shape stable. The length of cooling time will also affect the quality of the product. If the cooling time is too long, the product may be deformed. If the cooling time is too short, the product may not be completely shaped.

After cooling and shaping, the blister products need to be cut and trimmed to remove excess leftovers and make the size of the products more accurate. Punch, laser cutting and other methods can be used for cutting, which can be selected according to the product requirements and the manufacturer's equipment conditions. During the trimming process, pay attention to the appearance quality of the product to ensure that there is no defect and deformation. Blister packaging manufacturer Will carry out strict quality inspection on the products produced. The inspection contents include dimensional accuracy, appearance quality, physical properties, etc. Only products that meet the quality standards can be delivered for sale. The manufacturer will rework or scrap the unqualified products. Blister products that have passed the quality inspection will be packaged, usually using cartons, plastic bags and other packaging materials. Pay attention to product protection during packaging to avoid damage during transportation. Deliver packaged products to customers.

In short, Blister packaging manufacturer The production process of is a complex and delicate process, and the quality of each link needs to be strictly controlled to ensure the production of high-quality blister packaging products. With the continuous progress of science and technology and the changing market demand, blister packaging manufacturers are also constantly innovating and improving production processes to provide customers with better packaging solutions.
