Shrink Tunnels

Shrink wrapping is a technique that employs heat-sensitive shrink film to tightly contract around an object when heat is applied. There are three main types of shrink tunnels: recirculating, infrared, and steam tunnels.

Revolutionizing Packaging

Enhanced Packaging Security

Key features of shrink tunnels include the optional tray/board insertion, with speeds of up to 150 cycles per minute, and a design that emphasizes simplicity and robustness, making them easy to operate and maintain. These highly efficient and versatile machines also come in a fully stainless-steel version that is ideal for use in the dairy industry. Additionally, they are energy-efficient, making them a cost-effective choice for businesses.

Recirculating Tunnels

Recirculating shrink tunnels utilize heated air that circulates around the product, efficiently causing the shrink film to contract. These tunnels are renowned for their high speed and efficiency, making them suitable for large volume or high-speed operations, especially in industries like food packaging and retail.

Infrared Tunnels

Infrared shrink tunnels use infrared radiation to heat the shrink film, providing uniform and precise heat application. These tunnels are best known for their ability to handle a broad range of product sizes and shapes, ensuring a tight and smooth finish, making them ideal for industries requiring precise shrink wrapping such as cosmetics, pharmaceuticals, and electronics.

Steam Tunnels

Steam shrink tunnels use steam to heat the shrink film, delivering an even shrinkage that results in a superior finish. These tunnels are ideal for shrinking film around products with irregular shapes or for containers that require full-body shrink sleeves, often used in the beverage and pharmaceutical industries.
