Automatic Heat Shrink Wrapping Machine

Product Overview

This automatic heat shrink wrapping machine is a complete packaging system consisting of a film-feeding section, product conveyor, sealing and cutting unit, heat shrink tunnel, and finished-product outlet. Unlike a standalone shrink tunnel, this machine can place shrink film around the product, seal and cut the film, and then shrink it tightly around the package.

During operation, the product enters the sealing section on the conveyor. Shrink film is unwound from the film holder and guided around the product. The sealing cutter closes and separates the film, creating an individual film package. The wrapped product then travels through the heated shrink tunnel, where circulated hot air causes the film to contract around the product.

The machine is suitable for food, beverage, cosmetics, household products, stationery, hardware, daily commodities, and retail packaging. It can process individual products or grouped packages, depending on product dimensions and film configuration.

This system is intended for manufacturers that need continuous shrink wrapping with less manual film handling. Final suitability depends on the product size, package shape, shrink-film type, film thickness, heat sensitivity, and required production speed.

Applications

This machine is suitable for individual products or grouped packages that can be enclosed in heat-shrink film and conveyed steadily through the sealing and shrinking sections.

This machine is suitable for:

• Bottled water multipacks
• Beverage bottles
• Canned products
• Food cartons
• Cosmetic boxes
• Soap boxes
• Tissue packs
• Pharmaceutical cartons
• Stationery products
• Books and printed products
• Hardware boxes
• Electronic accessory boxes
• Gift boxes
• Bagged commodities
• Tray-packed products

A packaging test is recommended for lightweight products, heat-sensitive items, unstable bottles, sharp-edged cartons, irregular packages, or printed films requiring precise sealing and shrinking control.

Main Features

1. Complete Shrink Packaging Process

The machine combines product conveying, film feeding, wrapping, sealing, cutting, heat shrinking, and finished-product discharge in one integrated packaging system.

2. Automatic Film Feeding

Roll-fed shrink film is installed on the film holder and guided into the wrapping section for continuous product packaging.

3. Integrated Sealing and Cutting

The sealing cutter closes the shrink film around the product and separates each package before it enters the heating tunnel.

4. Continuous Conveyor System

The conveyor transfers products through the wrapping, sealing, shrinking, and discharge stages with reduced manual movement between separate machines.

5. Heat Shrink Tunnel

The enclosed tunnel applies controlled heat to the sealed film, causing it to contract and fit closely around the product.

6. Separate Control Sections

The sealing and cutting unit and the shrink tunnel have separate control panels, allowing their operating settings to be managed according to the packaging requirement.

7. Waste Film Collection

The visible waste-collection section gathers excess film produced during sealing and cutting, helping keep the working area more organized.

8. Pneumatic Monitoring

A pressure gauge is installed on the packaging section to support monitoring of the pneumatic system used during machine operation.

9. Emergency Stop Control

The machine includes an emergency stop switch positioned near the main operating area for rapid shutdown when required.

10. Mobile Machine Structure

Universal caster wheels support machine positioning, installation adjustment, maintenance access, and production-line arrangement.

Working Principle

Products are placed on the infeed conveyor and transferred toward the film-wrapping section. Shrink film is unwound from the film-roll holder and guided around the product as it moves into the sealing area.

Once the product reaches the correct position, the sealing and cutting mechanism closes the film and separates the package from the remaining roll material. Excess film is transferred toward the waste-collection section.

The sealed package continues along the connection conveyor and enters the heat shrink tunnel. Heated circulating air causes the shrink film to contract around the product. After the required heating time, the package exits the tunnel through the finished-product outlet.

Conveyor speed, sealing temperature, sealing time, tunnel temperature, and film position should be adjusted according to product dimensions, film thickness, package shape, and heat sensitivity.

Process Flow:

Product Feeding → Film Unwinding → Product Wrapping → Film Sealing → Film Cutting → Shrink Tunnel Heating → Film Shrinking → Finished-Product Discharge

Machine Details

1. Film Roll Holder

The film-roll holder supports the shrink-film roll and supplies film continuously to the wrapping and sealing section.

2. Film Installation and Feeding Unit

This section guides the shrink film into the correct position and helps form the film around the incoming product.

3. Product Infeed Conveyor

The conveyor carries products into the wrapping area and maintains movement through the sealing and cutting process.

4. Sealing Cutter

The sealing cutter closes the film around the product and cuts the completed film package away from the remaining roll material.

5. Sealing and Cutting Control Panel

This control section manages the operating functions of the product conveyor, film feeding, sealing, and cutting mechanism.

6. Pressure Gauge

The pressure gauge displays the operating pressure of the pneumatic system used by the sealing and cutting section.

7. Waste Film Collection Unit

The collection section receives excess film produced during sealing and cutting and helps prevent loose waste film from accumulating around the machine.

8. Connection Conveyor

The intermediate platform transfers the sealed package smoothly from the sealing unit into the heat shrink tunnel.

9. Heat Shrink Tunnel

The tunnel heats the sealed film package and causes the film to contract around the product during continuous conveyor movement.

10. Finished-Product Outlet

The outlet conveyor discharges the completed shrink-wrapped packages for cooling, inspection, carton packing, palletizing, or other downstream handling.

Technical Parameters

Packaging & Shipping

The final packing method, number of shipping cases, packed dimensions, and gross weight should be confirmed according to the complete machine configuration. Because the system includes a sealing and cutting unit, shrink tunnel, conveyors, and connecting sections, it may require separate packing for transportation.

Before shipment, the film-feeding system, sealing cutter, conveyor movement, shrink tunnel, control panels, emergency stop, pneumatic system, and electrical configuration should be checked against the confirmed order.

Testing with the customer’s actual product and shrink film is recommended when samples are available. The machine should be cleaned, secured against movement, and protected from moisture before transportation.

Freight, customs clearance, import duties, destination charges, installation arrangements, and local delivery should be confirmed separately with the buyer.

FAQ

Q1: Is this a complete shrink wrapping machine or only a shrink tunnel?

This is a complete shrink wrapping system. It includes film feeding, product conveying, film wrapping, sealing, cutting, heat shrinking, and finished-product discharge. A standalone shrink tunnel only performs the heating and shrinking stage.

Q2: What products can the machine package?

The machine can package suitable cartons, bottles, cans, boxes, bags, trays, books, cosmetics, household products, hardware, and grouped retail products. Final suitability depends on product dimensions, package stability, film type, and heat sensitivity.

Q3: What shrink film can be used?

The supplied product information confirms POF shrink film. Compatibility with other films should be verified according to film thickness, sealing temperature, shrink temperature, shrink ratio, and the selected machine configuration.

Q4: Can the machine package multiple bottles together?

Grouped bottles may be shrink wrapped when the selected film width, product-arranging method, sealing area, tunnel opening, conveyor width, and package stability match the required multipack format. Product testing is recommended before confirming the configuration.

Q5: What information is required before ordering?

Please provide the product dimensions, product weight, packaging arrangement, film type, film thickness, required package appearance, target output, local voltage, compressed-air availability, and photos or samples of the finished package.
