Automatic Flanging and Sealing Machine for nail-free glue can

For no-nail adhesive packaged in paper cans, the can sealing process requires more than simply placing a lid onto the container. After the adhesive has been accurately filled, the paper can enters a dedicated expanding and sealing station where the can opening is prepared and the lid is securely sealed.

Guangzhou Full Harvest Industries Co., Ltd. provides automated packaging equipment for different industrial and consumer products. Our Automatic Paper Can Expanding & Sealing Machine is designed specifically for the packaging process after filling, combining can opening expansion and sealing into a continuous operation.

The Packaging Process Starts After Filling

The most important feature of this solution is its process sequence.

The paper can is filled with no-nail adhesive first. Once filling is completed, the filled can is conveyed into the expanding and sealing machine.

The production flow is:

Paper Can Feeding → No-Nail Adhesive Filling → Filled Can Conveying → Can Expanding → Lid Sealing → Finished Product

This configuration allows the expanding and sealing process to directly follow the filling operation.

Why Expand the Can After Filling?

After the no-nail adhesive has been filled into the paper can, the container opening needs to be prepared for the sealing operation.

The expanding station adjusts the opening structure before the lid enters the sealing section. This provides the required conditions for the following sealing process and helps the lid fit correctly with the paper can.

By arranging these two operations together, the filled cans can move directly from expanding to sealing without unnecessary manual transfer.

A Continuous Solution for Adhesive Packaging

The machine is designed around the actual production sequence of filled paper cans.

Once the filled can enters the machine, the container is conveyed and positioned automatically. The expanding mechanism processes the can opening, after which the can proceeds to the sealing station.

This helps create a smooth transition between:

Filling → Expanding → Sealing

For manufacturers producing no-nail adhesive at scale, this continuous workflow can reduce repetitive manual handling and improve the overall efficiency of the packaging line.

Focused on No-Nail Adhesive Applications

No-nail adhesive is a product where packaging integrity is particularly important. The container needs to remain securely closed during storage, transportation, and distribution.

Using an automated expanding and sealing process after filling can help manufacturers achieve a more consistent packaging workflow while maintaining the appearance and integrity of the finished paper can.

The solution can be considered for:

• No-nail adhesive
• Construction adhesives
• Industrial adhesives
• Other suitable products packaged in paper cans

The actual machine configuration can be adapted according to the paper can diameter, height, opening structure, lid design, adhesive characteristics, and production capacity.

What Happens Inside the Machine?

The operation can be divided into several coordinated stages:

01 — Filled Can Infeed
The filled paper cans arrive from the upstream adhesive filling machine.

02 — Can Positioning
The containers are accurately positioned for the expanding process.

03 — Opening Expansion
The can opening is processed to prepare it for lid sealing.

04 — Can Sealing
The lid is applied and the paper can is securely sealed.

05 — Finished Can Outfeed
The sealed cans are transferred to the next packaging stage.

This arrangement allows the machine to work as a dedicated post-filling can expanding and sealing station.

Integration with a Complete Adhesive Packaging Line

The machine can be connected directly with upstream filling equipment and downstream labeling or product collection equipment.

A complete no-nail adhesive packaging line can be configured as:

Empty Paper Can Handling
↓
No-Nail Adhesive Filling
↓
Automatic Paper Can Expanding
↓
Automatic Can Sealing
↓
Labeling / Coding
↓
Finished Product Collection

This setup reduces manual intervention between individual processes and helps manufacturers build a more continuous automated production line.
