Packaging Industry Drying Tunnel Furnace
Category：Tunnel Oven Production Line
Introduction
The Packaging Industry Drying Tunnel Furnace is a continuous hot air circulation heating system specially designed for rapid drying and curing of surface coatings, printing inks, adhesives, and heat shrink packaging materials.The equipment uses conveyor belts or mesh belts to continuously transport materials, allowing products to undergo uniform drying inside a constant-temperature tunnel. It is a key drying system widely used in large-scale packaging production lines.
Applications
Ink Printing Drying:
Used for rapid drying of surface inks after packaging printing on cardboard boxes, labels, plastic films, and other packaging materials.
Adhesive Curing:
Used for thermal melting and rapid curing of adhesives in composite packaging bags, paper boxes, and bonded packaging structures.
Surface Coating Drying:
Used for heating and drying moisture-proof coatings, varnishes, and protective coatings on packaging containers.
Heat Shrink Packaging:
Used for heating and tightening plastic shrink films on bottled products, canned products, and bundled goods.
