The sheet used for blister packaging is called hard sheet or film, commonly used are: pet (polyethylene terephthalate) hard sheet, pvc (polyvinyl chloride) hard sheet, ps (polystyrene) hard sheet. PS hard sheet has low density, poor toughness, and is easy to burn. It will produce styrene gas (hazardous gas) when burned, so it is generally used to produce various industrial plastic trays. PVC hard sheet has moderate toughness and is not easy to burn. It will produce chlorine gas when burning, which will have a certain impact on the environment. PVC is easy to heat seal, and can be sealed by sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products. Pet hard sheet has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high. It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on the surface of pet, named petg hard film, but the price is higher.

What is suction card packaging? What problems should be paid attention to in suction card packaging?

Blister card packaging refers to heat-sealing the blister on the surface of the paper card with blister oil, which is often used for battery packaging in common supermarkets. Its characteristic is that it needs blister sealing equipment to seal the product between the paper card and the blister. The problems that should be paid attention to are: 1. It is required that the surface of the paper card must be covered with blister oil (so that it can be heat-sealed with the pvc blister); 2. The blister can only be made of pvc or petg sheet; 3. Because the blister is only glued On the surface of the paper card, so the packaged product will not be too heavy.

What is card packaging? What problems should be paid attention to in card packaging?

Insert card packaging refers to the packaging form of inserting paper cards and transparent blisters folded over three sides. Its characteristic is that no packaging equipment is required for packaging, and workers only need to put the product, blisters and paper cards in place. The problems that should be paid attention to are: 1. The size of the paper card and the folded blister is appropriate. If they are inserted too tightly, the paper card and blister will be deformed; if they are too loose, they will be easily separated. 2. When the product is too heavy, it is necessary to consider using staples to fix the paper card and the blister at a certain position.

What is semi-blister packaging? What problems should be paid attention to in semi-blister packaging?

The full meaning of semi-blister packaging is double-blister packaging in which the product is half exposed. It refers to the packaging form in which the paper card and the product are packaged together with two blisters, but the product is partially exposed outside the blister. It is suitable for special long-term packaging. The product. Its characteristic is that it is necessary to manually use scissors to cut off the part exposed to the product on the blister, and then use a high-frequency machine to seal the double blister. The efficiency is low and the packaging cost is high, but the visual effect is good, and it can satisfy users. When purchasing products, directly touch the needs of the products. Things to pay attention to: 1. It is not easy to use this kind of packaging for products that are easy to get dirty; 2. When cutting holes on the blister, pay attention to the neat edges; 3. The blister must use PVC or petg hard sheets.

What is double blister packaging? What problems should be paid attention to in double blister packaging?

Double blister packaging refers to the packaging form in which the paper card and the product are packaged together with two blisters. Its characteristic is that a high-frequency machine is required to seal the edges of the double blisters, which is low in efficiency and high in packaging costs, but the edges are neat and beautiful, and the appearance of the product is high-grade. The problems that should be paid attention to are: 1. Blister shell can only use pvc and petg film, otherwise it cannot be heat-sealed or the heat-sealing effect is not good; 2.

Folding blister packaging means that one side of the double blister is connected together during blister molding, and the bottom and surface of the double blister are formed after being folded in half. Its characteristic is that instead of using high-frequency edge banding technology, it can be buckled at a certain position of the blister to connect the double blisters. If necessary, it can also be marked with staples. In terms of material selection, pet hard sheets can be used to achieve environmental protection. purpose of the material. Problems that should be paid attention to: 1. Since there is no high-frequency edge banding machine, the edge needs to be cut with high quality on the cutting machine; 2. The tightness of the buckle should be moderate.

What is tri-fold blister packaging? What problems should be paid attention to in tri-fold blister packaging?

Tri-fold blister packaging is to fold the blister into three sides (front, bottom, back), forming an extra bottom edge so that the product can stand on a flat surface.

If necessary, it can also be marked with staples. In terms of material selection, pet hard sheets can be used to realize environmentally friendly materials. The purpose is suitable for large-diameter product packaging. Problems that should be paid attention to: 1. Since there is no high-frequency edge banding machine, the edge needs to be cut with high quality on the cutting machine; 2. The tightness of the buckle should be moderate.

What is external semi-blister packaging? What problems should be paid attention to in external semi-blister packaging?

Its characteristic is that a high-frequency machine is required to seal the edges of the double bulbs and make strap holes on them. The efficiency is the lowest and the packaging cost is high, but it can meet the needs of users to touch the product.
