What Are Blister Plasters?

A plastic processing technology, the main principle of which is to flatten hard plastic sheets after heating and softening, use vacuum adsorption on the mold surface, and cool and mold. They are widely used in plastic packaging, lighting, advertising, decoration and other industries.

Blister

Chinese name: Blister
Types of: Plastic processing technology

Application: Packaging, lighting, advertising, decoration and other industries
Including

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

Blister packaging equipment mainly includes:

Thermoforming process flow chart

General process: plastic sheet-cutting-sheet fixing-heating-forming-demoulding-blanking-finished product

[Requirement of material for blister molding]:

1. Blister molding can only produce products with relatively uniform wall thickness (usually thinner at the chamfer), and cannot produce plastic products with very different wall thicknesses.

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

3. The stretch of plastic molded products is limited to a certain extent.

Blister products

Plastic products are processed by plastics. The principle of product generation is to heat flattened hard plastic materials and soften them, then use vacuum to adsorb on the surface of the mold, and then cool them to form plastic products. Industry, food industry, hardware tools, cosmetics industry, toy industry, daily necessities industry, medicine, health products, automobiles, stationery, sports and other categories of industries.

Blister packaging

Blister packaging products mainly include: blister, tray, blister box, synonyms also include: vacuum cover, blister, etc.

Blister

The transparent plastic hard sheet is made into a specific convex shape transparent plastic by a plastic suction 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 bubble shell, it can be divided into: single bubble shell, double bubble shell, card bubble shell and card bubble shell

Blister box

It is a type of blister product with a lid and a bottom. The bottom and the lid are called a double-folded blister box, and the bottom and the lid are separated.

Blister tray

It is also called a plastic inner tray. The plastic hard sheet is made of plastic with a specific groove by a suction process. The product is placed in the groove to protect and beautify the product.

Blister flocking inner support

It is a blister tray with special materials. The surface of ordinary plastic hard sheet 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 quality of packaging products.

Blister antistatic tray

It is a blister tray using a special material, and the resistance value of the surface of the material is less than 10 11th ohm. Mainly used for blister trays for electronic and IT products.

Blister mould

The mold used in the production of blister molding has the lowest cost is the plaster mold, followed by the electroplated copper mold, and the most expensive is the aluminum mold. A small hole is drilled in the mold, which is used for vacuum adsorption of the heated hard piece to form a blister product.
