1, if classified according to the thickness of the material, it can be divided into
A. Ordinary thin blister thickness of 0.14 ~ 5.0mm --- mainly using PVC, PP, PS (HIPS), PET (including APET and PETG), PE, BOPS and Recyclable Paper Holder and other materials and effects Folding, folding, tri-fold, cylinder, folding box, world box, high frequency and other non-thermoforming Plastic Products are widely used in food, medicine, electronics, toys, computers, daily necessities, cosmetics and mechanical hardware industries.
B. Thickness of special thick plastic blister is 0.14~8.0mm --- Mainly uses PVC, PP, PS (HIPS), PET (including APET and PETG), ABS, PC, PE, PMMA and other materials and effects of injection molding Type of plastic products, the main products are refrigerator liners, advertising light boxes, merchandise display racks, pet cage chassis, rear projection TV rear shell and a variety of mechanical panels, etc., can replace injection products, with low mold costs (only injection mold 1 /20), the production cycle is short, the mold development time is short (usually as long as 3 to 5 days) and so on.
The reason why the classification is not based on the type of materials is that there are some differences between the materials used in ordinary thin plastic blister and special thick plastic blister, but PVC, PP, PS and PET are in both plastic blister products. With a place to live, it is called the “Four Heavenly Kings” of the family of plastic products.
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.
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.
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.
PVC sheet is a widely used and popular material, PVC film can be divided into two kinds of food grade and industrial grade, and can be made transparent, color, anti-static, gold-plated, flocking and other various sheet materials For vacuum molding, its main characteristics are high transparency, good surface gloss, less crystal spot, small water mark, wide application, high impact resistance, and easy molding. The products are made to meet the US FDA, Japanese PL food hygiene standards, and made into products. Widely used in toys, food, Electronic Products, medicine, electrical appliances, gifts, cosmetics, stationery and other product packaging.

Gold-plated (silver) materials are mainly used for electroplating into gold or silver on various materials and eye-catching materials, which are mainly not suitable for high-end food packaging and Christmas ornaments (such as mooncakes, chocolates, Christmas bells, etc.).
4, if classified according to the structure of the product, it can be divided into
Undercarriage, inner care, outer cover, suit, card, card, double blister, half blister, folded blister, tri fold blister, cylinder foldable box, world box, high frequency, ultrasonic, process blister (such as Wall calendars, masks, etc.) and model blister (such as cars, boats, TV back covers, etc.).
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.
The issues that should be noted are:
1. The size of the paper card and the blister that folds over the edge are appropriate, and the paper card and the blister are deformed too tightly; if they are too loose, they can 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.
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 issues that should be noted are:
1. It is required that the surface of the paper card must be filled with plastic oil (so that it can be heat-sealed with the PVC blister);
2. Bubble shell can only use PVC or PETG sheet;
3. Since the blister only sticks to the surface of the paper card, the packaged product is not too heavy.
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.
The issues that should be noted are:
1. Bubble shell can only use PVC and PETG film, otherwise it can not heat or heat sealing effect is not good;
2. The quality of high-frequency molds determines the quality of double-bubble shell edges.
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. Care should be taken to ensure that the edges are neat when cutting holes in the bulb;
3. The blister must use PVC or PETG hard film.
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.
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 cut in a high-quality cutting bed;
2. The tightness of the buckle should be moderate.
The three-fold blister package is to fold the blister into three sides (front, bottom, back) and form a bottom edge so that the product can stand on the plane. Its characteristic is that it can not use high-frequency edge-sealing technology. Instead, it uses a certain position in the bulb to connect the bulb shell. If necessary, it can also use staples. In terms of material selection, PET hard film can be used to achieve environmental protection materials. The purpose is suitable for large-caliber product packaging.
Should pay attention to the problem:
1.Because there is no high-frequency machine edge, the edge needs to be cut in a high-quality cutting bed;
2. The tightness of the buckle should be moderate.
