Heat Tunnel for shrink sleeves

Dase-Sing’s electric heat tunnels for shrink sleeves provide a steam-free solution for shrink sleeve labeling. These systems are ideal for empty bottles that cannot withstand steam pressure, as well as moisture-sensitive products like pharmaceuticals, and for bottle cap sealing. Since they don’t require boilers or steam piping, heat tunnels are also a practical choice for smaller production spaces or facilities without steam infrastructure.

Our heat tunnels for shrink sleeves are built for precise, uniform heating across a wide variety of bottle shapes and materials. A unique internal air diversion system ensures even heat distribution, while temperature controllers allow accurate settings with minimal fluctuation (±5°C). The machines are constructed with stainless steel or heat-resistant coated steel for long-term durability, and support PVC, PET, and OPS shrink sleeve materials. Their modular design makes installation, operation, and product changeovers simple and efficient.
