Shrink tunnels are industrial machines used in the packaging process to apply heat to shrink plastic film or shrinkable material around a product or package. The heat causes the film to shrink tightly and conform to the shape of the item, creating a secure and protective seal. Shrink tunnels are commonly used in various industries, including food and beverage, pharmaceuticals, electronics, cosmetics, and retail. Overall, It plays a crucial role in the packaging process, providing a secure and visually appealing packaging solution for various industries.
VIBGYOR TECHNOPLUS SPECIALIZES in designing and building custom-made shrink tunnels according to customer requirements. Our shrink tunnels are low on maintenance, support a green environment and because of precise temperature controls give the best shrinkage results.
FOOD AND BEVERAGE, CONSUMER DURABLES, AUTOMOTIVE INDUSTRY, PAPER INDUSTRY, PHARMACEUTICAL INDUSTRY, STATIONERY ITEMS, E-COMMERCE, ELECTRONICS, HEALTHCARE, ETC.
Key features of shrink tunnels include:
1. Heat Source: Shrink tunnels use different heat sources, such as electric heating elements or hot air systems, to generate the necessary heat for shrinking the plastic film.
2. Conveyor System: It is equipped with a conveyor system that moves the packages or products through the tunnel. The conveyor ensures even and consistent heat distribution for uniform shrinkage.
3. Temperature Control: It is have temperature controls that allow operators to adjust the heat settings based on the type of film being used and the product requirements.
4. Variable Speed: Some shrink tunnels come with adjustable conveyor speed to accommodate different production rates and package sizes.
5. Adjustable Airflow: Hot air shrink tunnels may have adjustable airflow settings to optimize the shrinking process for specific types of packaging materials.
6. Cooling Zone: Some advanced of it have a cooling zone at the end of the tunnel to set the shrunken film quickly and prevent deformation once it leaves the heat area.
7. Safety Features: It is designed with safety features to protect operators from potential burns or accidents during operation.
It is work in conjunction with shrink wrapping machines, which apply the plastic film to the product or package before entering the tunnel. The process generally follows these steps:
1. The product or package is placed on the conveyor of the shrink wrapping machine, and the film is dispensed and wrapped around it.
2. The wrapped product enters the shrink tunnel on the conveyor belt.
3. Inside the tunnel, the film is exposed to controlled heat, causing it to shrink and tightly conform to the shape of the product or package.
4. As the product moves through the tunnel, the shrunken film sets and forms a secure seal around the item.
Benefits of using shrink tunnels:
1. Protection and Tamper Resistance: Shrink tunnels create a tight seal around products, providing protection from dust, moisture, and tampering during transit or storage.
