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 hard sheet or film. Commonly used are: PET (polyethylene terephthalate) hard sheet, PVC (polyvinyl chloride) hard sheet, PS (polystyrene) hard sheet . PS hard film has low density, poor toughness, and is easy to burn. When it is burned, it will produce styrene gas (which is a harmful gas), so it is generally used to produce various industrial plastic trays. PVC hard sheet has moderate toughness, is not easy to burn, and generates chlorine when it is burned, which has a certain impact on the environment. PVC is easy to heat and can be sealed by 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, does not produce harmful gases when burning, and belongs to environmental protection materials, but its price is high, and it is suitable for high-grade plastic products. Generally, PET plastic film is required for plastic blister in European and American countries, but It is not easy to heat, and it brings great difficulties to the package. To solve this problem, people laminate a layer of PVC film on the surface of the PET, which is named PETG hard film, but the price is higher.
2. What is the card packaging? Card packaging should pay attention to what the problem?
The card packaging refers to a packaging form in which a paper card is inserted together with a transparent bulb folded over three sides. The feature is that the packaging does not require any packaging equipment, and only the workers need to place the product, the blister pack and the paper card in place. Attention should be paid to the following issues: 1. The size of the paper card and the blister that folds over the edge is appropriate. If it is inserted too tightly, the paper card and the blister will be deformed; if it is too loose, it will easily detach. 2. When the product is too heavy, it is necessary to consider fixing the paper card and the bulb with a staple at a certain position.
3. What is blister card packaging? Blister card packaging should pay attention to what the problem?
The blister card packaging refers to the heat sealing of the bulb on the surface of the paper card with the plastic oil. Common supermarket battery packs are used for this purpose. Its feature is the need for blister sealing equipment to seal the product between the paper card and the blister. The problems that should be noted are: 1. The surface of the card must be filled with plastic oil (so that it can be heat-sealed together with the PVC bulb); 2. The foam shell can only be used with PVC or PETG sheet; 3. Because the bubble shell is only sticky On the paper card surface, the packaged product is not too heavy.
4. What is double blister packaging? Double blister packaging should pay attention to what the problem?
Double blister packaging refers to a package that uses two blister packs to enclose the paper card with the product. It is characterized by the need for high-frequency machines to seal double-bubble shells, which has low efficiency and high packaging costs. However, the edges are neat and beautiful, and the appearance of the products is high-end. Attention should be paid to the following issues: 1. The blister can only be made of PVC and PETG film, otherwise it cannot be heat-sealed or heat-seal poorly; 2. The quality of the high-frequency mold determines the quality of the double blister edge.
5. What is half-shell packaging? Half blister packaging should pay attention to what the problem?
The half-blister package is intended to be a product with a double-blown double-bubble package, which refers to a two-bubble package that encloses the paper card with the product, but the product is partially exposed outside the bulb, and is suitable for long The product. It is characterized by the need for manual use of scissors to first cut the exposed part of the product on the blister, and then use a high frequency machine to double blister sealing, low efficiency, high packaging costs, but the visual effect is good, and can meet the user in the supermarket pick When touching a product, touch the product directly. Should pay attention to the problem: 1. Easy to bring dirty products is not easy to use this type of packaging; 2. In the blister cut hole should pay attention to the edge neat; 3. blister must use PVC or PETG hard film.
6. What is the external half-shell packaging? External half-shell packaging should pay attention to what the problem?
The external half-bubble packaging means that all the products are externally placed outside the double-bubble shell. The double-bubble shell only encloses the paper card and serves as the bottom of the product head, and the product is connected with the plastic wrap of the bulb shell. Its characteristic is that it needs a high-frequency machine to seal the double-bubble shell, and hit the strap hole on it, which has the lowest efficiency and high packaging cost, but it can meet the needs of users touching the product.
7. What is folded blister packaging? What should you watch out for when you fold blister packs?
Folded blister packaging refers to the fact that one side of the double-bubble shell is joined together during the suction molding process, and the bottom and the face of the double-bubble shell are formed after folding. Its feature is that it can not use high-frequency edge-sealing technology. Instead, it uses a certain position in the bulb to connect double-bubble shells. If necessary, it can also use staples. In terms of material selection, PET hard films can be used to achieve environmental protection. The purpose of the material. Should pay attention to the problem: 1. Because there is no high-frequency machine edge, the edge needs to be completed in the cutting bed high-quality cutting; 2. The buckle tightness should be moderate.
