Information

1. What are the commonly used plastic sheets for blister packaging? What are the characteristics of each? Answer: The sheet used for blister packaging is called rigid film or film. Commonly used are: PET (polyethylene terephthalate) rigid film, PVC (polyvinyl chloride) rigid film, PS (polystyrene) rigid film . PS hard film has low density, poor toughness, and is easy to burn. It will produce styrene gas (a harmful gas) when burned, so it is generally used to produce various industrial blister trays. PVC hard film has moderate toughness and is not easy to burn. It will produce chlorine when burned, which will affect the environment. PVC is easy to heat and can be sealed with a sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products. PET hard film 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, and it is suitable for high-end blister products. The blister blister in European and American countries generally requires PET hard film, but 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 rigid sheet, but the price is higher.

2. What is the card packaging? What should be paid attention to when inserting card packaging? Card-inserted packaging refers to a packaging form in which a paper card and a transparent blister folded over three sides are inserted together. Its characteristic is that it does not require any packaging equipment during packaging, and only requires workers to put the product, blister and paper card in place. The problems that should be noted are: 1. The paper card and the folded blister are of the right size. If they are inserted too tightly, the paper card and the blister will be deformed; if they are too loose, they will be easily separated. 2. When the product is too heavy, consider fixing the paper card and the blister at a certain position with staples.

3. What is blister card packaging? What should be paid attention to when packaging the blister card? Blister card packaging refers to the heat-sealing of the blister on the surface of the paper card with blister oil, which is commonly used in supermarket battery packaging. It is characterized by the need for blister sealing equipment to encapsulate the product between the paper card and the blister. The problems that should be paid attention to are: 1. The surface of the paper card must be covered with blister oil (so that it can be thermally bonded with the PVC blister); 2. The blister can only be made of PVC or PETG sheets; 3. Because the blister is only sticky On the surface of the paper card, the packaged product is not easy to be too heavy.

4. What is double blister packaging? What should be paid attention to in double blister packaging? Double blister packaging refers to a packaging form that uses two blisters to encapsulate the paper card and the product. It is characterized by the need for a high-frequency machine to seal the edges of the double blister, which has low efficiency and high packaging costs, but the edges are neat and beautiful, and the product appearance is high-end. The problems that should be paid attention to are: 1. The blister can only use PVC and PETG film, otherwise it cannot be heat-sealed or the heat-sealing effect is not good; 2. The quality of the high-frequency mold determines the quality of the edge of the double blister.
