Stretch Wrapping Machine for Automatic Pallet Packaging

The Stretch Wrapping Machine for Automatic Pallet Packaging is designed to automatically wrap palletized products with stretch film for secure handling, storage and transportation.

Featuring a cantilever rotary arm wrapping system, the machine keeps the pallet load stationary while the wrapping arm rotates around the pallet. This helps provide consistent film application while reducing manual wrapping work.

The machine can be integrated with automatic palletizers, pallet conveyors, strapping machines and other end-of-line packaging equipment to create a complete automated pallet packaging system.

Automatic Pallet Wrapping for End-of-Line Packaging

After products are palletized, the finished pallet is transferred to the stretch wrapping station by a pallet conveyor.

The rotary arm rotates around the stationary pallet while the film carriage moves vertically to wrap the required height. Film tension and wrapping parameters can be adjusted according to the product, pallet dimensions and packaging requirements.

After the wrapping cycle is completed, the stretch film is cut and secured, and the wrapped pallet is transferred to the next production or storage process.

This automated process is suitable for manufacturers looking to reduce manual pallet wrapping and improve the consistency of final pallet packaging.

Key Features

Cantilever Rotary Arm Design

The cantilever wrapping arm rotates around the stationary pallet instead of rotating the pallet itself.

This design is suitable for automated pallet packaging applications where stable load handling is important.

Automatic Stretch Film Wrapping

The machine automatically applies stretch film around the palletized load according to preset wrapping parameters, reducing repetitive manual wrapping operations.

Adjustable Film Tension

Film tension can be adjusted according to different products and packaging requirements to help achieve stable and consistent pallet wrapping.

Programmable Wrapping Cycle

Wrapping speed, wrapping height and wrapping cycles can be adjusted according to the pallet size and load characteristics.

Automatic Film Cutting

After the programmed wrapping cycle is completed, the film can be automatically cut and secured, reducing manual intervention.

Easy Integration with Pallet Conveyors

The stretch wrapping machine can be connected with pallet conveyors to create a continuous automatic pallet packaging process.

It can also be integrated with palletizers, strapping machines and other end-of-line equipment.

How Does a Stretch Wrapping Machine Work?

The automatic pallet wrapping process generally includes the following steps:

1. Pallet Infeed

The palletized products enter the wrapping station through the pallet conveyor.

2. Film Attachment

The stretch film is attached to the pallet load or designated wrapping position.

3. Rotary Arm Wrapping

The cantilever rotary arm rotates around the stationary pallet while applying stretch film around the load.

4. Vertical Film Movement

The film carriage moves vertically to cover the required wrapping height.

5. Film Tension Control

The film delivery system controls film tension during wrapping to achieve consistent film application.

6. Film Cutting and Securing

After the preset wrapping cycle is completed, the film is cut and secured.

7. Finished Pallet Discharge

The wrapped pallet is transferred by the pallet conveyor to the next packaging, storage or shipping process.

Stretch Wrapping Machine for Can Manufacturing

For tin can and 3-piece can production lines, automatic pallet wrapping can be used as part of the final pallet packaging process.

After empty cans or other metal packaging products are palletized, the pallet can be transferred automatically from the can palletizer to the stretch wrapping machine.

A typical automated process can include:

Can Palletizer → Pallet Conveyor → Stretch Wrapping Machine → Strapping → Finished Pallet

This configuration reduces manual handling between palletizing and final packaging and helps create a more continuous end-of-line automation process.

The system can be configured according to the customer's pallet dimensions, product characteristics, production speed and factory layout.

Applications

The automatic stretch wrapping machine can be used for palletized products in various industries, including:

• Food and beverage packaging
• Tin can and metal packaging
• Empty can production
• Carton and case packaging
• Plastic containers
• Industrial products
• General palletized goods
• End-of-line manufacturing and packaging

For can manufacturing plants, the machine can be integrated with empty can palletizers, robot palletizers, pallet conveyors and other end-of-line packaging equipment.

Benefits of Automatic Pallet Packaging

Manual stretch wrapping can require repetitive labor and may result in inconsistent film tension and wrapping quality.

An automatic stretch wrapping machine helps manufacturers improve the consistency and efficiency of pallet packaging.

Main benefits include:

• Reduced manual wrapping labor
• More consistent film application
• Improved pallet load stability
• Adjustable wrapping parameters
• Reduced manual handling
• Easy integration with pallet conveyors
• Suitable for automatic palletizing systems
• Improved end-of-line packaging efficiency

Stretch Wrapping Machine for Palletizer Integration

The stretch wrapping machine can be installed downstream of different palletizing systems.

For example:

Robot Palletizer → Pallet Conveyor → Stretch Wrapping Machine

or

Automatic Palletizer → Pallet Conveyor → Stretch Wrapper → Strapping Machine

This allows manufacturers to connect palletizing and final packaging into a more complete automatic production process.

For existing production lines, the conveyor layout and machine configuration can be customized according to the available factory space.

Technical Specifications

Final technical specifications depend on the customer's pallet dimensions, product characteristics, production capacity and factory layout.

Customized Automatic Pallet Packaging Solution

Every production line has different pallet dimensions, product characteristics and available space.

Baoli can customize the stretch wrapping machine and pallet conveying system according to the customer's production requirements.

Before recommending a suitable configuration, we normally need the following information:

• Product type
• Pallet size
• Pallet load height
• Pallet load weight
• Required production capacity
• Stretch film specifications
• Existing conveyor layout
• Available installation space

Based on these details, Baoli can recommend a suitable automatic pallet wrapping configuration and integration method.

Frequently Asked Questions

What is a stretch wrapping machine?

A stretch wrapping machine is an automatic packaging machine that applies stretch film around palletized products to stabilize the load for handling, storage and transportation.

What is a cantilever stretch wrapping machine?

A cantilever stretch wrapping machine uses a rotating arm to wrap stretch film around a stationary pallet. The pallet does not need to rotate during the wrapping process.

Can the stretch wrapping machine be connected to a palletizer?

Yes. The machine can be connected to automatic palletizers, robot palletizers and pallet conveyors to create an automated end-of-line packaging system.

Can it be used for empty cans?

Yes. The machine can be used for palletized empty cans and other metal packaging products when the pallet configuration and wrapping requirements are suitable.

Can the machine be customized?

Yes. Baoli can customize the machine configuration and conveyor connection according to pallet size, load height, production capacity and factory layout.

What information is needed for a quotation?

Please provide the pallet dimensions, load height, load weight, production capacity and available factory layout. Photos or drawings of the existing production line are also helpful for determining the suitable configuration.
