Shrink Wrapping｜Spray Cans

Horizontal Flow Wrapper, Shrinkable Type PSA-250WS with Shrink Tunnel FS-300 (CE) intergrate with product arrangement and conveying, as well as product discharge for Spray Can Shrink Packaging Line

How Can Filled Spray Cans Be Integrated into an Automated Packaging Line?

Spray cans are widely used for household cleaning products, industrial supplies, automotive care, personal care, and various aerosol products. After filling and capping, some products are further packaged with shrink film to help protect the product from dust, maintain package integrity, and create a cleaner, more professional appearance for retail presentation.

Spray cans typically leave the filling process in an upright position, while flow wrapping requires appropriate product feeding and transfer into the packaging machine. When a line combines product handling, conveying, film sealing, heat shrinking, and collection, the interface between each stage can directly affect packaging appearance, line efficiency, and overall production performance.

This project was developed for an established spray can manufacturer evaluating an automated packaging line. The customer wanted to determine whether shrink flow wrapping could be integrated with its existing production process and to assess the equipment configuration, line integration, and capacity requirements needed for future mass production.

After evaluating the product, packaging requirements, production speed, and available floor space, Benison developed an integrated spray can feeding and shrink flow wrapping solution based on the customer’s actual production needs, creating a complete packaging process from upstream product infeed through downstream collection.

Why Use Shrink Flow Wrapping for Spray Cans?

For brands that value package appearance and consistency, packaging serves not only as protection but also as an important brand touchpoint at retail. Flow wrapping combines sealing and shrinking to conform the film to the product, creating a neat, transparent appearance that enhances presentation and overall packaging quality.

Spray can diameter, can structure, actuator or nozzle design, packaging material, and production speed can all influence equipment configuration and final packaging results. Benison therefore evaluates actual product samples and production requirements before recommending suitable packaging equipment, film specifications, and operating parameters.

▍Packaging Challenges

This project required more than installing a single packaging machine. The solution had to integrate the customer’s existing production process, product characteristics, and packaging requirements. After the initial assessment, three key packaging challenges were identified:

Maintain Consistent Spray Can Packaging Appearance： The customer placed strong emphasis on retail presentation and wanted the shrink film to conform neatly around the can with fewer wrinkles, air pockets, or uneven shrink areas, while maintaining reliable seals and a consistent finished package.
Integrate the Filling Line with Horizontal Flow Wrapper： After filling and capping, spray cans are conveyed upright, while the flow wrapping process requires a different product infeed arrangement. The line therefore needs coordinated feeding, product handling, and conveying so the cans can transition efficiently into the flow wrapping process.
Balance Packaging Speed, Floor Space, and Collection： After shrink wrapping, finished products must move efficiently to inspection, manual collection, or the next packaging process. Downstream conveying was therefore planned around the required packaging speed, available floor space, and operator workflow to reduce product accumulation and improve handling efficiency.

▍Benison's Packaging Solution

After evaluating product specifications, production requirements, packaging format, and line conditions, Benison selected the PSA-250WS Horizontal Flow Wrapping with the FS-300 (CE) Shrink Tunnel. Product handling, conveying, and collection were integrated to create a complete spray can shrink flow wrapping line.

The complete line includes:

Spray can infeed and product handling configuration
Product conveying design
Shrink flow wrapping
Conveying and product collection

Through complete line integration and process planning, the automated packaging solution is configured according to the actual can diameter, height, nozzle structure, and required production capacity.

How Can Spray Cans Be Integrated with Horizontal Flow Wrapper?

Integrating filling with packaging requires a solution matched to the spray can shape, infeed direction, and existing production process. Benison plans the line around actual products and site requirements to connect filled and capped cans with flow wrapping while reducing manual handling.

How Can Spray Cans Be Fed into Horizontal Flow Wrapper Effectively?

When cylindrical spray cans are packaged horizontally, rolling or lateral movement during conveying can affect the infeed position and final package appearance. Benison evaluates the can dimensions, shape, and packaging requirements to configure the appropriate infeed arrangement, helping products enter the flow wrapping process accurately and consistently while supporting a clean, well-finished shrink package.

How Are Finished Spray Cans Transferred for Downstream Collection?

After flow wrapping and heat shrinking, finished spray cans may proceed to inspection, manual collection, or secondary cartoning depending on the production setup. Benison incorporates downstream conveying into the overall line design based on available floor space, packaging speed, and operator workflow, helping manage product transfer and provide a more efficient handoff for collection or subsequent packaging operations.

By integrating handling, conveying, flow wrapping, shrinking, and collection, this project established a practical line configuration for connecting the customer’s existing spray can production process with automated shrink packaging.

What Are the Advantages of This Packaging Line?

This line integrates product infeed and handling, flow wrapping, heat shrinking, and conveying. The layout is planned around product characteristics, required production speed, and available floor space to improve transfer between packaging stages and reduce manual handling, rearrangement, and repetitive product organization between machines.

Based on the product shape and packaging requirem ents, the flow wrapping machine and shrink tunnel are configured to achieve good film clarity, conformity, and consistent sealing after heat shrinking, helping improve package presentation and retail shelf appeal.

The line can also be adapted to future product specifications, capacity increases, and automation requirements. Product inspection, automatic cartoning, or other downstream equipment can be evaluated as part of future upgrades, giving manufacturers greater flexibility for production expansion.
