Blister Packaging Quiz

1. What is double blister packaging?
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.

2. What is blister card packaging?
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.

3. What is the card packaging?
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.

4. What is flocking?
It is a kind of blister tray using special materials. It will stick a layer of velvet material on the surface of ordinary plastic hard sheet, so that the surface of the tray has a kind of velvet texture, which can be used to improve the grade of packaging products.

5. What is a plastic box?
Broadly speaking, it refers to all blister shells, but in a narrow sense, it is just a type of blister: it is formed into a plastic box shape by sheet plastic, and the lid is connected to the container. Made of PS, there are also separate lids and bottoms. Different materials can be used. If the Japanese fast food box has a black PS, the cover is made of transparent PET.

6 plastic commonly used materials which? What are the characteristics of each?
A: The plastic sheet is called hard sheet or film, and the thickness is more than 2mm called sheet, commonly used are: PET (polyethylene terephthalate) hard sheet, PVC (polyvinyl chloride) hard sheet, PS ( Polystyrene) hard sheets, ABS (Engineering Plastics). 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. The materials used for thick plates are: ABS, Acrylic (Perspex), PS, PC, PVC, etc.
