Steam Shrink Tunnel Machine - Automatic Bottle Label Packaging

Demonstration of square bottle shrinking

Product Introduction

This steam shrink tunnel is a standardized industrial-grade packaging equipment designed for shrink encapsulation

of labels, bottle neck sleeves and other scenarios. The machine is built with a food-grade steam generation module,

which outputs stable saturated steam through a constant temperature and pressure control system, ensuring uniform

heating and tight adhesion of shrink films/labels during the shrinking process, avoiding wrinkles, bubbles or damage.

The top exhaust system can discharge residual steam in a timely manner to keep the workshop environment dry.

The equipment is compatible with various shrink film materials such as PVC and POF, supports packaging of bottle

necks and labels of different sizes, and widely meets the mass production needs of food & beverage, daily chemical

and other industries.

Core Advantages

✅ Food Grade Safety：The steam generation system is made of food-grade 304 stainless steel, with clean

and impurity-free steam, complying with food contact material safety standards.

✅ Uniform Shrinkage：Constant temperature & pressure control technology combined with full-area

steam injection ensures 360° uniform heating of labels/films, with tight adhesion and no wrinkles after shrinkage.

✅ High Efficiency & Stability：Fully automatic high-speed operation, suitable for continuous production of

assembly lines.

✅ Easy Maintenance Design：Open frame + modular components facilitate the inspection, repair and cleaning

of core components such as steam generators and pipelines.

✅ Energy Saving & Environmental Friendly：Closed-loop steam circulation system reduces heat loss, saving

about 20% energy compared with traditional equipment, with no waste gas residue.
