Hanging: There is a kind of blister packaging called card insertion packaging. The three edges of the blister need to be folded to the back by a folding machine, so that in the next packaging process, the paper card is inserted into the folding edge to form the card insertion packaging.

Pull line: some undesirable line protrusions (not on the mold) produced during blister molding production need to be modified (reduce the height and increase the smoothness of the mold) and add additional pressure mold (we call it the upper mold) to solve. When the cable is too large, it is regarded as a defective product and cannot be used for high quality blister packaging. However, in the field of parts turnover tray, as long as the cable is neatly arranged and does not affect the use function, it should be regarded as a qualified product. The pull line is also called: rachus, cramp, etc.

Scratch: The blister product, especially the transparent blister, has scratch marks. If the marks are too long and too large, the blister will become defective and cannot be used for high quality packaging.

Crystal point: in the blister sheet production process, due to the fine dust in the air, fell on the heated plastic material, resulting in a transparent flaw, especially in the transparent blister sheet production process, this flaw is too large, too much, as defective.

Bubble: in the blister sheet production process, because the heated plastic material contains air, so that the finished sheet produced with bubbles, especially in the transparent blister sheet production process, the bubble is too large, too much, as defective.

Water ripple: in the production process of blister sheet, due to different materials and processing technology, the surface of the finished sheet produced has water ripple, especially in the production process of transparent blister sheet, this kind of water ripple is too large, too much, it is regarded as defective. In general, the thicker the sheet, the more pronounced the water ripples. Qualified pet materials rarely have water ripples, but most pvc have water ripples.

Heat sealing: is a blister packaging process, with a sealing machine will be coated with blister oil on the surface of the paper card and blister heat together to form a blister card packaging.

High frequency sealing: it is a kind of blister packaging process, which uses high frequency machine to generate high frequency, and glues the bubble shell together to form double bubble shell packaging.

Ultrasonic sealing: it is a kind of blister packaging process. ultrasonic wave is generated by ultrasonic machine, and the blister and blister are bonded together to form double blister packaging. unlike high frequency sealing, ultrasonic wave can not only seal pvc and petg materials, but also seal pet materials, and has no electromagnetic damage to the packaged products. it is especially suitable for packaging electronic products. The disadvantage is that ultrasonic sealing edges can only be spaced dots, and usually only one straight edge is sealed at a time.
