1. Blister: A plastic processing technology. The main principle is to heat and soften the flat plastic sheet or sheet (thick sheet blister). It is vacuum-adsorbed on the surface of the mold, cooled and molded, and widely used in plastic packaging. , lighting, advertising, decorative car and boat accessories, household appliances liner (such as refrigerator liner), door panels, lighting, luggage, decorative parts, slides, furniture, sanitary ware, lamps, toys, teaching equipment, art advertising, transportation Marks, pallet liners and other industries. Commonly used materials are: ABS. PP. PS. PVC. EPS. HIPS. PE. HDPE. PC. PMMA and other thermoplastics.
2, blister packaging: the use of plastic process to produce plastic products, and the corresponding equipment for the packaging of the product. Blister packaging products mainly include: blister, tray, plastic box, synonym: vacuum cover, blister and so on. Blister packaging 3, equipment mainly includes: plastic molding machine (automatic plastic forming machine, thick sheet plastic forming machine), punching machine, sealing machine, high frequency machine, folding machine. The packaged product formed by the package can be divided into: card, suction card, double bubble shell, half bulb shell, double folded bulb shell, three fold bulb shell and the like.
4. Bubble shell: The transparent plastic hard sheet is made into a transparent plastic with a specific convex shape by a plastic blister process, and covers the surface of the product to protect and beautify the product. Also known as blister, vacuum cover, plastic mask. According to the form of the blister, it can be divided into: single blister, double blister, card blister and blister shell
4. Blister box: It is a kind of plastic product with cover and bottom. The bottom and the cover are connected together by a double-folded plastic box. The bottom and the cover are separated by a bottom cover plastic box.
5. Blister tray: Also called plastic inner tray, the plastic hard sheet is made into a specific groove plastic by the plastic process, and the product is placed in the groove to protect and beautify the product.
6. Flocking inner support: It is a kind of plastic tray with special materials. The surface of the ordinary plastic hard sheet is glued with a layer of fluffy material, so that the surface of the tray has a velvety feel, which is used to improve the grade of the package. .
7. Antistatic tray: It is a plastic tray with special materials. The surface resistance of the material is less than 10 11 ohms. Mainly used for plastic trays for electronic and IT products.
8. Blister mold: The mold used in the production of plastic forming, the lowest cost is the plaster mold, followed by the electroplated copper mold, the most expensive is the aluminum mold. The mold is drilled with small holes for vacuum adsorption of the heated hard sheets to form a blister product.
9. Blister molding: It is the blister that we often talk about. It uses a plastic molding machine to adsorb the softened plastic sheet on the surface of the mold. After cooling, it forms a plastic with concave and convex shape.
10, plastic cutting: plastic products after plastic molding, through the punch, the large sheet of paper is cut into individual products with a knife mold. Also called cutting, cutting, die cutting, etc.
11. Folding: There is a kind of blister packaging in the blister packaging. The three sides of the blister need to be folded to the back with a folding machine, so that in the next packaging process, the paper card is inserted into the hem to form a plug. Card packaging.
12, pull wire: some of the undue line protrusions produced during the production of plastic forming (not on the mold), need to re-modify the mold (reduced height and increase the degree of gardening) and add additional pressure mold (we call it Solve) to solve. When the cable is too large, it is regarded as a defective product and cannot be used for high-grade blister packaging. However, in the field of component turnover trays, as long as the wires are arranged neatly and do not affect the function of use, they should be regarded as qualified products. The pull line is also called: Laqiu, cramps and so on.
13. Scratch: There are scratch marks on the blister finished product, especially the transparent blister. If the trace is too long and too large, the blister becomes a defective product and cannot be used for high-grade packaging.
14. Crystal point: in the production process of blister sheet, due to the fine dust in the air, it falls on the heated plastic material, resulting in a transparent enamel, especially in the production process of transparent blister sheets. When the species is too large, when it is too much, it is considered as a defective product.
15. Air bubbles: In the production process of blister sheet, air is contained in the heated plastic material, so that the finished product sheet has bubbles, especially in the production process of transparent blister sheet. Large, too much, is considered a defective product.
16. Water ripple: In the production process of blister sheet, due to different materials and processing techniques, the surface of the finished sheet produced has water surface ripple, especially in the production process of transparent blister sheet. Too big, too much, is considered a defective product. In general, the thicker the sheet, the more pronounced the water ripples. There are few water ripples in qualified PET materials, but most PVCs have water ripples.
17. Heat sealing: It is a plastic packaging process. The paper card with the plastic oil coated on the surface is heat-sealed with a sealing machine to form a blister card package.
18. High-frequency sealing: It is a blister packaging process. A high-frequency machine is used to generate high-frequency, and the blister and the blister are bonded together to form a double blister package.
19. Ultrasonic sealing: It is a blister packaging process. Ultrasonic machine is used to generate ultrasonic waves. The blister and the blister are bonded together to form a double blister package. Unlike the high frequency sealing, the ultrasonic can not only seal the PVC. PETG material can also seal PET material, and there is no electromagnetic damage to the packaged product, especially suitable for electronic product packaging; the disadvantage is that ultrasonic edge sealing can only be spaced dots, and generally only one straight at a time side.
