Thermoforming&Blister

The thermoforming & Blister forming line is a complete set of automated equipment that heats plastic sheets to a softened state, forms them by vacuum or pressure molding, and then cools, trims, and collects the finished products.
The line usually uses plastic sheets such as PET, PVC, PS, and  PP as raw materials and is widely used in food, pharmaceutical, electronics, and daily consumer packaging industries.

Types of Thermoforming & Blister

According to different forming methods and application fields, Thermoforming & Blister can be divided into the following types:

  • Vacuum Thermoforming
    Uses vacuum suction to make the heated sheet fit the mold. The structure is simple and suitable for thin-walled products.
  • Pressure Forming
    Combines vacuum and compressed air, providing higher forming accuracy and better surface details.
  • Blister Forming
    A typical application of thermoforming is mainly used for pharmaceutical and small product packaging.



Composition of Thermoforming & Blister Line

①Sheet Heating System

The sheet heating system usually adopts infrared or ceramic heating to ensure uniform heating and proper softening of plastic sheets for forming.

②Forming Mold

The mold determines the shape and size of the product and can be customized according to customer requirements for different structures and depths.

③Vacuum / Pressure System

Vacuum pumps and pressure systems are used to make the sheet closely fit the mold surface, ensuring forming accuracy and stability.

④Cooling System

The cooling system is used to quickly reduce the temperature of the formed product and ensure dimensional stability.

⑤Cutting Device

The cutting device separates the formed products from the scrap edges, ensuring a neat appearance and consistent dimensions.

⑥Stacking / Collecting System

Finished products are output through stacking, conveying, or automatic collecting systems, facilitating subsequent packaging or transportation.

Working Principle of Thermoforming&Blister

Plastic sheets are fed into the heating zone by the conveying system. After being heated to a softened state, they enter the forming station and are molded under vacuum or pressure. The products are then cooled, trimmed, and automatically collected.

Application Fields

Thermoforming & Blister products are widely used in the following industries:

  • Food packaging (trays, food containers, fruit boxes)
  • Pharmaceutical packaging (blister packs)
  • Electronics and hardware packaging
  • Daily necessities and consumer goods packaging
