Brief introduction of blister packaging

【Chinese Packaging Network News】 Blister products: listen to the name to know that plastic is used as raw material. The process is to flatten the plastic hard sheet material and heat it to soften it, and vacuum it to adsorb on the surface of the mold and wait for cooling to form.

Blister products are widely used in electronics, electrical appliances industry, food industry, hardware tools, pharmaceuticals, health products, automobiles, sports goods and other categories of industries.

The use of blister packaging has brought more convenience to our lives.

The market has been changing all the time. What we need to do is to seize the strings of the times and make progress together with the times.

First, plastic packaging products category

Blister packaging products include: blister, tray, plastic box, also can be called: vacuum cover, blisters and so on.

Blister

The transparent plastic hard sheet is changed into a specific convex shape transparent plastic in the manufacture of the blister process, covering the surface of the product, thereby protecting and beautifying the product. Alias ​​blister, vacuum cover, plastic mask. According to the form of blister can be divided into: single blister, double blister, card blister and blister blister.

Blister "tray"

Alias ​​plastic inner care, the use of plastic technology to plastic sheet made of special groove plastic, the product placed in the groove, protect and beautify the product.

Plastic boxes

This type of blister product has a bottom with a cover, the bottom and the cover are connected together and folded plastic box, the bottom and the cover are called the bottom cover blister box.

Flocking Netto

Blister trays are made of special materials, and a layer of velvety material is glued on ordinary plastic hard sheets to make the surface of the trays feel velvety, which is used to improve the grade of packaging products.

Antistatic tray

Like flocked inner trays, special materials are used, and the surface resistance is less than 10 11 ohms. It is mainly used for plastic trays for electronics and IT products.

Second, the advantages of plastic packaging products

The main advantages of blister packaging

1. Consumables are greatly reduced, weight is reduced, transportation is convenient, sealing performance is excellent, and it belongs to the category of environmental protection green packaging;

2. Any shaped product can be packaged without any auxiliary buffer material when it is packaged;

3. The product is transparent and visible through the plastic packaging process, has a beautiful appearance, is easy to sell, belongs to mechanization, automated packaging, modern management, saving manpower and improving efficiency.

Third, blister packaging technology and equipment

Blister packaging equipment mainly includes:

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

Thermoforming process flow:

Plastic Sheets - Cutting - Sheet Fixing - Heating - Molding - Demolding - Stripping - Finished Products

Fourth, plastic molding material requirements

1. Blister molding is only applicable to products with relatively uniform wall thickness and cannot produce extremely poor wall thickness plastic products.

2. Within the range of 1 to 2 mm or thinner is a normal category (the most common thickness of sheets for blister packs for small packages is 0.15 to 0.25 mm).

3. The degree of stretching of plastic molded products is subject to certain restrictions. The ratio of the diameter to the depth of plastic molded plastic containers is generally not to exceed 1, and in extreme cases it must not exceed 1.5.

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