detail

Blister products are processed with plastic. The principle of product production is to heat and soften the flat plastic hard sheet material, vacuum adsorb on the mold surface, and then cool to form. Blister products are widely used. They are mainly used in electronics and electrical appliances. Industry, food industry, hardware tools, cosmetics industry, toy industry, daily necessities industry, medicine, health products, automobiles, stationery, stationery and sports goods and other categories of industries.

 

1. Classification of blister packaging

 

Blister packaging: a general term for producing plastic products using a blister process and packaging the products with corresponding equipment. Packaging products formed by packaging can be divided into: insert card, suction card, double bubble shell, half bubble shell, half-folded bubble shell, tri-folded bubble shell, etc. Blister packaging products include: blister shells, trays, blister boxes, synonyms are: vacuum hood, blister, etc.

Blister

A transparent plastic hard sheet is made into a transparent plastic with a specific convex shape by a plastic absorbing process, which is covered on the surface of the product to protect and beautify the product. Also known as blister, vacuum mask, plastic mask. According to the different forms of bubble shells, it can be divided into: single bubble shells, double bubble shells, plug-in bubble shells and suction card bubble shell

 

Plastic boxes

It is a kind of blister product with lid and bottom. The bottom and lid are connected together and called half-folded blister box. The bottom and lid are separated and called the bottom cover blister box.

 

Blister "Tray"

It is also called plastic inner support. It adopts plastic suction process to make plastic hard sheet into plastic with specific groove. The product is placed in the groove to protect and beautify the product.

 

Flocking inner support

It is a blister tray made of special materials. A layer of velvet material is adhered to the surface of the ordinary plastic hard sheet, so that the surface of the tray has a velvety feel, which is used to improve the grade of packaging products.

 

Antistatic tray

It is a blister tray made of special materials. The resistance value of the surface of the material is less than 10 to the 11th ohm. Mainly used for plastic trays of electronic and IT products.

 

Blister "mold"

For the molds used in the production of blister molding, the lowest cost is the gypsum mold, followed by the electroplated copper mold, and the most expensive is the aluminum mold. The mold is drilled with small holes, which are used to vacuum adsorb the thermalized hard sheet to form a blister product.

 

Second, the main advantages of plastic packaging products

The main advantages of blister packaging are: saving raw and auxiliary materials, light weight, convenient transportation, and good sealing performance, which meets the requirements of environmentally friendly green packaging; it can pack any special-shaped products, and no additional cushioning material is required for packaging; the packaged products are transparent and visible. Beautiful appearance, easy to sell, and suitable for mechanized and automated packaging, which is convenient for modern management, saving manpower and improving efficiency.

 

3. Production equipment and process of blister packaging

Blister packaging equipment mainly includes:

Plastic molding machine, punching machine, sealing machine, high frequency machine, folding machine.

 

Thermoforming process flow:

Plastic sheet-cutting-sheet fixing-heating-forming-demolding-removing edge-finished product

 

Fourth, the requirements of plastic molding materials

1. Plastic molding can only produce products with relatively uniform wall thickness (generally thinner at the chamfer), and cannot produce plastic products with widely different wall thickness

2. The wall thickness of the blister forming is generally within the range of 1 to 2mm or thinner (the most commonly used thickness of the blister packaging sheet for small packaging is 0.15 to 0.25mm)

3. The stretch of plastic molded products is subject to certain restrictions. The diameter ratio of plastic molded plastic containers generally does not exceed 1, and in extreme cases it should not exceed 1.5

4. The dimensional accuracy of plastic molding is poor, and the relative error is generally more than 1%.
