The Steam-Operated Shrink Tunnel from USA Pack Machines LLC delivers consistent, high-quality shrink wrapping for retail products or bundled packages. Designed with precision engineering, this machine ensures wrinkle-free, smooth sleeve applications while maintaining energy efficiency and long-lasting reliability. Using the power of steam, the tunnel distributes heat evenly around containers, guaranteeing a flawless shrink finish. Whether applied to glass, plastic, PET, or metal containers of varying shapes and sizes, the system adapts seamlessly to diverse packaging requirements. As a result, manufacturers gain enhanced product appeal, improved protection, and dependable performance across every production cycle.

The Steam-Operated Shrink Tunnel integrates effortlessly with an Automatic Shrink Sleeve Label Applicator Machine, making it the preferred choice for OPS and PVC sleeves of 40–50 microns. Operators manually load bottles or containers onto the conveyor, where the tunnel’s re-circulating steam chamber surrounds each product with uniform heat. With four-way directional airflow, sleeves shrink tightly without wrinkles or distortion.

A precise temperature controller allows users to select optimal settings for different products and shrink films. Silicon rubber tunnel curtains minimize heat loss while maintaining consistent internal conditions. In addition, a variable-speed drive gives flexibility to adjust conveyor speed based on package dimensions and film characteristics. After each cycle, the tunnel’s automatic cool-down and shut-off mode not only extends equipment life but also enhances operator safety. The robust construction ensures years of virtually maintenance-free operation, reducing downtime and increasing productivity.
