Frequently Asked Questions
What is the purpose of a Heat Shrink Tunnel?
A heat shrink tunnel applies controlled hot air around shrink film, causing it to contract tightly around the product and create a secure, attractive, and tamper-resistant package.
Which packaging machines can this tunnel be used with?
It can be integrated with sleeve wrapping machines, L-sealers, semi-automatic shrink wrappers, and fully automatic shrink wrapping systems.
Why does the tunnel use a mesh conveyor?
The mesh conveyor provides stable product movement while allowing uniform hot air circulation around the package for consistent shrinking.
Which shrink films are compatible with the tunnel?
The tunnel is suitable for LDPE, PVC, POF, and other commonly used shrink films, depending on the application requirements.
Can the temperature and conveyor speed be adjusted?
Yes. The tunnel is designed with adjustable temperature and conveyor speed controls, allowing it to accommodate different products, film types, and packaging requirements.
Which industries use Heat Shrink Tunnels?
Heat shrink tunnels are widely used in food and beverage, pharmaceuticals, cosmetics, FMCG, household products, electronics, and industrial packaging applications where consistent and professional shrink packaging is required.
