Q&A on the quality of blister packaging

The crystal point is a point on them blister packaging aterial, which will seriously affect the appearance of the blister packaging product. The quality problem comes from the sheet supplier. The reason for this is that when the sheet is produced, there are debris mixed In the material, this kind of quality situation occurs, and the solution is to inspect the sheet before producing the blister packaging product.

How is the uneven thickness caused? How to solve such a problem?
There are several common points for uneven thickness, such as shelf, sheet, temperature, etc. It is very important to adjust the position of the product when it is put on the shelf. If there is a dislocation or unreasonable placement, it will cause uneven thickness. What is related to the sheet is that the thickness of the sheet is not adjusted during the production process, so it will cause such a quality problem. The temperature adjustment is also directly related, and the corresponding temperature should be adjusted according to the different materials of different molds, otherwise there will be uneven phenomenon. The solution is to pay attention to the adjustment of the position of the shelf, the negotiation of the supplier of the sheet, and the temperature adjustment to the suitability of the sheet and the mold.

What is a pull wire? How did it happen? How to solve?
The pulling line is a protruding line on the edge of the product, which seriously affects the appearance of the packaging. The reason for the formation is that this situation is related to the structure and manufacture of the plastic mold. The controlled operation of the plastic molding machine, The temperature adjustment has a great relationship with the shelf, and the solution is the quality control of the mold, the adjustment of the machine and temperature parameters, and the shelf extrusion.

What are water ripples and bubbles? How? How to solve?
Water ripples and bubbles are watermarks and bubble points on the surface of the material. Such blister products will directly affect the appearance of the packaged items and reduce the appearance of the packaged items. The cause of the water ripple is the relationship between the sheet manufacturer and the sheet in the production process, and the water ripple is related to the speed of the production of the film. The reason for the bubbles is that the temperature is too high during sheet production or caused by the mixed production of sheets or the infiltration of air during sheet production. Materials with bubbles will lead to perforation and deformation of blister packaging products, becoming defective products. The method is that the quality of the sheet must be observed when the material is purchased or before production before storage or production.

What are scratches? How is this quality problem caused? How to solve?
Scratches are scratches that appear on the surface of blister products after they are produced, and are also a frequent problem in quality. The reason is that in the production process, there are many manual processes, which are prone to collision and friction. Punch personnel and packaging personnel The way of operation is the key link. The solution is to handle the product with care, keep the worktable clean and hygienic, and wear gloves and other related matters for staff, which can also effectively prevent scratches. There are many manual processes for blister packaging products. Every link must be paid close attention to avoid defective products.

The use industry of blister tray

Blister tray refers to a type of plastic tray formed by blister molding process. It is mainly used for industrial products, electronic products, and food packaging. The thickness ranges from 0.2mm to 2mm. The blister tray adopts the blister process to make the plastic hard sheet into plastic with a specific groove, and the product is placed in the groove to protect and beautify the product. There are also transport-type tray packaging. Convenience is the main thing.
There are many types of blister trays. The tray product is one of the types of blister in the blister industry. This type of tray has a strong bearing capacity. According to the shape, structure and weight of the item, the tray packaging that is suitable for the strength is set. The thickness of the material used is also various. Different, depending on the packaging needs of the packaged items to make a choice, the blister products produced are widely used in the packaging of electronics, toys, hardware, medicine, food, stationery, etc. The above products can be provided according to different requirements of customers. PET, PP , PS, PVC, conductive, anti-static, flocking and other sheets made of various trays. Generally, transparent blister trays are more commonly used in packaging, and other colors can be selected according to individual needs. Commonly used in the electronics industry, toy industry, stationery industry, technology product industry, cosmetics industry, health care product industry, etc. Commonly used materials are PVC, PS hard film. When used in the food and pharmaceutical industries, environmentally friendly materials are mostly used: HIPS, BOPS, PP and PET.

Various types of plastic packaging boxes

Oral liquid inner support (oral liquid is based on traditional Chinese medicine decoction, extracts active ingredients from medicines, adds additives such as correctives, bacteriostatic agents, etc., and is made by injection ampoules filling and sealing process. or semi-sterile oral liquid preparations, hence the name oral ampoules.)
Water needle inner support (water needle is usually a solution of medicines, and the active ingredients have been dissolved in normal saline or glucose when it leaves the factory, which can be injected directly or diluted with normal saline or glucose for injection.)
Minute needle inner support (the needle is generally unstable in the solution, it is in powder form when leaving the factory, and it is packed in ampoules and injection bottles. Before use, it must be dissolved with 0.85% normal saline or 5% glucose injection before injection. .)
Bottle inner holder (inner holder for various plastic bottles)
Granule inner support (inner support for various bag shocks)
Special-shaped tray (internal tray of other shapes)

Can plastic boxes be heated in microwave

Nowadays, the use of microwave ovens is more and more frequent, and it is more and more able to meet more needs. When the demand for plastic boxes to be placed in microwave ovens was raised, it was generally believed that plastics were not resistant to high temperatures and were impossible to achieve. But in fact, plastic boxes can be heated in microwave ovens, which only refers to PP5 plastic boxes.
The common plastic packaging boxes on the market are No. 1, No. 5, and No. 6. Let’s take a closer look.
1. No. 1 plastic box refers to No. 1 polyethylene terephthalate (PET), which does not have heat resistance and will deform when heated. It is often used in the outer packaging of mineral water and beverages.
Second, No. 5 polypropylene is the PP5 mentioned above. It has good mechanical properties and heat resistance, can withstand high temperatures of 200 ° C, and can be repeatedly heated for use.
3. No. 6 polystyrene (PS), which is often used in instant noodle boxes and milk tea cups. Although the texture is very hard, it is easy to tear, and it is very peculiar, not resistant to high temperature, low temperature, and releases chemicals when heated, so it cannot be used for microwave heating.
