Shrink Tunnel for Bottles | sr-labeling

A shrink tunnel for bottles is a piece of equipment used in packaging operations to apply shrink sleeves, labels, or wraps onto bottles. The shrink tunnel works by applying heat to shrink the material tightly around the contours of the bottles for a secure and professional finish.

Types of Shrink Tunnels for Bottles

1. Steam Shrink Tunnels:

Use steam to evenly distribute heat around the bottles.

Best for irregularly shaped bottles, as the steam can conform to complex contours.

Common in food and beverage industries.

2. Infrared (IR) Shrink Tunnels:

Use infrared radiation to generate heat.

Suitable for high-speed operations with uniform bottle shapes.

Energy-efficient and heats quickly.

3. Hot Air Shrink Tunnels:

Use circulated hot air to shrink labels or sleeves.

Versatile and cost-effective for standard bottle shapes.

Often used for lower-volume or less complex packaging requirements.

4. Hybrid Shrink Tunnels:

Combine steam and hot air or steam and infrared.

Offer flexibility for varying packaging needs.

Key Features

Adjustable Heat Settings: To accommodate different materials and thicknesses of shrink wrap.

Conveyor Systems: Move bottles through the tunnel at a consistent speed.

Compact or Large Designs: Depending on production volume and available space.

Material Compatibility: Supports PVC, PET, and OPS shrink sleeves.

Benefits

Provides a tamper-evident seal.

Enhances branding with high-quality, contour-fitting labels.

Works well with different bottle shapes and sizes.

Automates a part of the packaging process, increasing efficiency.

Considerations

1. Bottle Material: Ensure the heat does not damage the bottle or contents.

2. Production Speed: Choose a tunnel that matches your production line's speed.

3. Type of Shrink Sleeve: Material and thickness affect tunnel performance.

4. Space and Budget: Compact options are available for smaller operations.
