What material is the blister packaging

Blister packaging refers to a kind of plastic processing technology. The principle of production and processing is to put the prepared mold shape on the blister forming machine, and after heating the flat plastic sheet to soften, move it to the top of the mold and then use vacuum adsorption. The principle is attached to the surface of the mold, and it is formed after cooling. Blister packaging is divided into thin sheet and thick sheet.
Sheet blister packaging is mainly made of PVC, PP, PET, PETG, PS, GAG, BOPS, flocking, antistatic, conductive and other blister sheets. The main products include: blister tray, blister box, blister, vacuum cover etc. Blister packaging production process processing, choose wood mold, plastic mold, gypsum mold, electroplating mold or aluminum mold according to sample specifications or requirements. The plastic sheet is loaded into the applicable size, and then the sheet is put into the heating wooden cabinet to make it completely fixed, and then the wooden cabinet and the plastic sheet are placed on the constant temperature furnace for softening treatment. Put the softened plastic sheet together with the wooden cabinet in the vacuum chamber, turn on the suction switch, and suck out the air in the vacuum chamber. After the plastic sheet is cooled, the same concave package as the mold is obtained. After the production and processing of blister packaging products, the products are trimmed and finished, and then they can be sold after packaging.
The thickness of thin blister packaging is generally 0.14-2mm, and if it exceeds 2mm, it is a thick blister packaging. Sheet blister machine includes automatic high-speed blister forming machine, blister packaging machine on-board cutting machine, high frequency machine, edge folding machine, sealing machine, punching machine, etc. Sheet blister packaging is widely used in food, electronics, stationery, toys, hardware, daily chemical gifts, medical and other industries. The blister packaging is of high quality and low price, which can beautify your products and attract more customers.

Thick-sheet blister packaging is mainly made of common materials such as ABS, PE, PMMA, PC, PVC, etc. From the production process, thick-sheet blister packaging has more processing processes such as milling, engraving, and grinding than thin-sheet blister packaging. Thicker, thick sheet blister thickness is generally 2mm-12mm. In terms of size, the thick sheet blister product can reach the molding size of 2800*1600*1000mm (length*width*height). Thick sheet blister is often used in large machine shells, charging pile shells, bubble houses, display stands, advertisements, bases, Image cards, sports equipment shells, beauty equipment shells, medical equipment shells, golf cart shells, sightseeing car roofs, turnover trays, game console shells, refrigerator liner, light boxes, etc. Thick sheet blister packaging equipment includes automatic thick sheet blister machine, semi-automatic thick sheet blister machine, CNC processing equipment, cutting machine, punching machine, etc.

The use and performance of anti-static plastic tray

The anti-static blister tray is a blister tray that eliminates static electricity. The anti-static tray has the characteristics of toughness, strong bearing capacity and high temperature resistance. It is lightweight, durable and stackable. It can be applied to various auto parts and electronic components.

The main purpose of antistatic plastic tray:
To eliminate static electricity, it is widely used in turnaround loading, packaging, storage and transportation of electronic devices and products in the production process. In the industry, it is also called a static conductive tray; the height of the tray is generally less than 100mm; it is suitable for the container for the turnover storage of precision electronic components. According to the customer’s electronic component requirements, there are different requirements for the size.

The anti-static blister tray is an ideal tool for storing electronic components. Due to the addition of special polymer chains in the raw materials, the finished product has long-term static dissipative properties. The finished product has good mechanical strength and heat resistance; good impact resistance and strong chemical corrosion resistance. It will not change its anti-static performance due to environment, time and temperature.

The anti-static blister tray can effectively release the static charge accumulated on the surface of the object, so that it will not generate charge accumulation and high potential difference; it can greatly reduce the damage rate of electronic products in the production process, reduce costs, and improve product quality and profit.

The performance of antistatic blister tray:
It has anti-folding, anti-aging, high bearing strength, tensile, compression, tearing, high temperature, and can be used for both turnover and finished product shipping. It is lightweight, durable and stackable. Various specifications and sizes can be customized according to user needs, with covers, dust-proof, anti-static, and beautiful appearance. Generally, anti-static trays are designed and manufactured according to the size provided by customers, so that they can be loaded reasonably, and multiple trays can be overlapped, making effective use of workshop space, increasing the storage capacity of electronic components, PCB boards, and dust-free workshop components, saving production costs.

What problems will occur when forming blister products

When the blister product is formed, factors such as pulling lines, scratches, crystal points, air bubbles, water ripples, etc. will appear.

Pull wire: Some unwanted line protrusions (not on the mold) produced during blister molding production, need to re-modify the mold (reduce the height and increase the roundness) and add additional pressure mold (we call it the upper mold) to solve. When the pull wire is too large, it is regarded as a defective product and cannot be used for high-end blister packaging. However, in the field of spare parts turnover trays, as long as the pull wire is neatly arranged and does not affect the use function, it should be regarded as a qualified product. Pull line is also known as: pull hill, cramp and so on.

Scratches: There are scratches on the finished blister, especially the transparent blister. If the marks are too long or too large, the blister will become a defective product and cannot be used for high-end packaging.

Crystal point: In the production process of blister sheet, a transparent defect caused by fine dust in the air falling on the heated plastic material, especially in the production process of transparent blister sheet Too large, too much, as defective.

Air bubbles: During the production of blister sheets, the heated plastic material contains air, so the finished sheet has air bubbles, especially in the production process of transparent blister sheets, if the bubbles are too large, If it is too much, it will be regarded as a defective product.

Water ripples: In the production process of blister sheets, due to different materials and processing techniques, the surface of the finished sheet has water ripples, especially in the production process of transparent blister sheets, the water ripples are too large , if it is too much, it will be regarded as a defective product. In general, the thicker the sheet, the more obvious the water ripples. Qualified PET materials rarely have water ripples, but most PVCs have water ripples.
