Double folded blister shell packaging means that one side of the double blister shell is connected together during blister molding, and the bottom and surface of the double blister shell are formed after being folded in half. Its feature is that instead of using high-frequency edge banding process, the double blister shells can be connected by making up positions at certain positions of the blister shells, and staples can be made when necessary. In terms of material selection, PET hard chips can be used to achieve the purpose of environmental protection materials.

Blister packaging is a kind of production process used by the plastic product industry for a long time. It can well teach and adjust the specifications and models of products, and can make corresponding product adjustments according to customer needs. When the inquiry process of blister packaging is almost completed, the manufacturer needs to give the corresponding quotation according to the actual needs of customers, the model of blister products and the selected materials. If the purchaser has other requirements such as expediting for the production cycle of the product, it also needs to verify the quotation according to the corresponding requirements. The quotation should conform to the facts, and should not be overestimated or underpriced.

Molding area and product area of blister packaging manufacturers. Forming area and product area: the forming area refers to the range of length and width inside the clamping frame; Product area refers to the area where traction stretching occurs during molding, which mainly depends on the size of blister products. In the heating process, the stretching part needs to be heated, and the stretching range is large. For the non product area with less heating amount, the stretching amount is also small. It should be noted that uneven heating will also cause uneven shrinkage after molding cooling and deformation of blister products.

What are the prevention methods of blister static electricity for blister packaging box manufacturers? Reduce or reduce friction to reduce the generation of static electricity: the accumulation of electric charges reduces the friction speed and friction coefficient, although it can achieve this goal, it will inevitably lead to the decline of production, which is unrealistic; In addition, adding a medium (oil) with a large dielectric constant e into the contact surface gap of the friction object can also reduce the accumulation of charges. However, this method can only be used in certain situations, and has no universal significance.

For the finished box, the adhesive shall be used to tear the film at the place. In order to ensure the practicability of the transparent plastic box after the next step of gluing, the excess film at the adhesive shall be removed. Glue is applied only after it is confirmed that there is no problem. Normally, this step is also a machine operation, but it is inevitable that some small workshops apply glue manually. The disadvantage of manual work is that the amount is small and the efficiency is low. The above is the production process of a transparent plastic box.
