Heat Shrink Tunnels 70-45 / 50-35 / 30-30 | Industrial Shrink Wrapping Tunnel Systems

Heat Shrink Tunnels 70-45 / 50-35 / 30-30

The GOLDPACK Heat Shrink Tunnel series (Models 70-45, 50-35, and 30-30) is engineered to deliver consistent, high-quality shrink wrapping results for industrial and semi-industrial packaging operations. Designed to operate in conjunction with L-shaped sealers or straight sealers, these tunnels complete the shrink process by applying controlled, uniform heat to shrink films tightly around the product.

Built with a robust carbon steel structure and finished with durable epoxy coating, these shrink tunnels are developed for long-term industrial reliability, stable performance, and minimal maintenance. Their optimized internal airflow system ensures even heat distribution across the entire chamber, resulting in a smooth, wrinkle-free, professional shrink finish.

Main Performance and Structural Features

Heavy-Duty Industrial Construction

• Reinforced carbon steel frame

• Epoxy paint finish for corrosion resistance

• High-quality thermal insulation for efficient heat retention

• Designed for continuous production environments

Advanced Heating & Air Circulation System

The tunnels are equipped with armoured resistance heating elements that provide stable and efficient heat generation. A digitally controlled temperature system allows precise adjustment based on film type and product size.

• Digital temperature control for accurate heat management

• Optimized forced-air circulation for uniform shrink results

• Stable thermal performance during long production cycles

• Fast heat recovery to maintain production consistency

Operational Flexibility

These shrink tunnels are compatible with a wide range of shrink films, including PE and similar industrial shrink materials. They are suitable for packaging individual products, multipacks, trays, and grouped items.

• Compatible with PE and other shrink films

• Suitable for small to medium production volumes

• Easy integration into new or existing packaging lines

• Smooth product transport through the heating chamber

Cost Efficiency & Production Optimization

By replacing traditional corrugated cardboard packaging with shrink film wrapping, the GOLDPACK shrink tunnel systems significantly reduce packaging material costs while maintaining strong product protection and improved visual presentation.

• Lower packaging costs

• Reduced material consumption

• Improved packaging appearance

• Efficient energy utilization

Available Models

• Tunnel 70-45 – Larger chamber for higher capacity applications

• Tunnel 50-35 – Medium-size tunnel for versatile production needs

• Tunnel 30-30 – Compact model ideal for limited space environments

Typical Applications

• Food and beverage packaging

• Industrial product bundling

• Multipack shrink wrapping

• Retail-ready packaging

• Replacement of carton-based packaging systems
