Blister packaging has become the mainstream army of hardware tool packaging on the market

First, the classification of blister packaging

Blister packaging: a general term for the production of plastic products by the blister process and packaging of the products with the corresponding equipment. The packaged products formed by the package can be divided into: card, suction card, double bubble shell, half bulb shell, double folded bulb shell, three fold bulb shell and the like. Blister packaging products include: blister, tray, plastic box, synonym: vacuum cover, blister and so on.

Bubble shell

The transparent plastic sheet is made into a transparent plastic with a specific convex shape by a blister process, and is covered on the surface of the product to protect and beautify the product. Also known as blister, vacuum cover, plastic mask. According to the form of the blister, it can be divided into: single blister, double blister, card blister and blister shell

Plastic boxes

It is a kind of blister product with a cover and a bottom. The bottom and the cover are connected together by a double-folded blister box, and the bottom and the cover are separated by a bottom cover blister box.

Blister "tray"

Also called plastic inner support, plastic plastic sheet is made into plastic with specific groove by blister process, and the product is placed in the groove to protect and beautify the product.

Flocking

It is a blister tray with special materials. The surface of ordinary plastic hard sheets is coated with a layer of velvet material, so that the surface of the tray has a velvety feel, which is used to improve the grade of the package.

Antistatic tray

It is a plastic tray with special materials. The surface of the material has a resistance value less than 10 11 ohms. Mainly used for plastic trays for electronic and IT products.

Blister "mold"

For the molds used in the production of plastic forming, the lowest cost is the plaster mold, followed by the electroplated copper mold, and the most expensive is the aluminum mold. The mold is drilled with small holes for vacuum adsorption of the heated hard sheets to form a blister product.

Second, the main advantages of blister packaging products

The main advantages of blister packaging are that it saves raw and auxiliary materials, is light in weight, convenient in transportation, good in sealing performance, and meets the requirements of environmentally friendly green packaging; it can package any shaped products, no additional buffering material is required for packing; the packaged products are transparent and visible. Beautiful appearance, easy to sell, and suitable for mechanization, automated packaging, easy modern management, saving manpower and improving efficiency.

Third, the production equipment and process of blister packaging

Blister packaging equipment mainly includes:

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

Thermoforming process:

Plastic sheet - cutting - sheet fixing - heating - forming - demoulding - stripping edge - finished product

Fourth, the requirements of plastic forming materials

1. Blister molding can only produce products with relatively uniform wall thickness (generally chamfered at a slightly thinner point), and can not produce plastic products with widely different wall thicknesses.

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

3. The stretchability of plastic molded products is limited. The diameter of plastic molded plastic containers is not more than 1 in diameter and should not exceed 1.5 in extreme cases.

4. The dimensional accuracy of plastic forming is poor, and the relative error is generally more than one percent.
