How glueless assembly technologies are changing the folding carton market

The packaging industry continues to rapidly change, driven by environmental concerns, automation, and the growth of the shipping sector. One of the most notable trends in recent years has been the development of packaging without traditional adhesives. This solution is gradually entering the market and is already being considered one of the future standards in paper packaging.

One of these innovations was the ActiBlu technology introduced by the company Smurfit Westrock. It allows for the assembly of cardboard packaging with virtually no adhesive joints. Instead of traditional gluing, a special coating is used that is activated by water and ensures a secure hold.

This approach changes the traditional understanding of cardboard packaging production and opens up new business opportunities.

How does glue-free technology work

In traditional packaging, structural elements are secured with adhesive. This requires additional materials, equipment, and production time.

The new technology uses a coating activation principle:
• a special layer is applied to the cardboard;
• it is activated upon contact with water;
• the packaging elements adhere without adhesive.

Additionally, the design of the boxes is thought out in such a way that the elements are fixed mechanically - through locks, flaps and bends.

The result is packaging that:
• assembles faster;
• does not require adhesive lines;
• remains strong and reliable;
• is suitable for automated processes.

Why the market is moving away from glue

The elimination of adhesive joints is not just a technological solution, but a response to several global industry challenges.

1. Easier recycling
Cardboard without adhesives is easier to recycle. Adhesives often degrade the quality of recycled materials, and their removal requires additional resources.

Glue-free packaging:
• is recycled faster;
• produces higher-quality secondary raw materials;
• better meets requirements circular economy.

2. Cost Reduction
For large volumes, eliminating glue provides significant savings, especially for chain stores and manufacturers with high workloads.

Allows you to reduce:
• material consumption;
• production costs;
• equipment maintenance.

3. Speeding up packaging processes
Speed ​​is essential in manufacturing and logistics.

Eliminating glue allows you to:
• speed up packaging assembly;
• reduce the number of steps;
• improve the efficiency of automated lines;
• reduce order processing time.

This is especially relevant for:
• food delivery;
• e-commerce;
• large-scale manufacturing;
• dark kitchens.

4. Reduced contamination during recycling
Glue-free packaging makes the recycling process cleaner and more predictable.

Adhesive joints may contain chemical components that:
• complicate recycling;
• degrade the quality of recycled materials;
• require additional cleaning.

Where will this packaging be used

This solution has the greatest potential in segments with a high packaging turnover.

1. Food delivery and fast food
Glue-free packaging fits these requirements perfectly, especially for bulk orders.

Here, the packaging must be:
• quick to assemble;
• inexpensive;
• convenient;
• resistant to stress.

2. Retail and e-commerce
Glue-free designs allow for faster product packaging and reduced operational costs.

In retail the following are important:
• packaging speed;
• compact storage;
• logistics optimization.

3. Production lines
These solutions are especially relevant for automated processes.

Advantages:
• fewer components requiring maintenance;
• lower risk of breakdowns;
• consistent packaging quality;
• high assembly speed.

Additional benefits

In addition to the main factors, adhesive-free packaging provides additional benefits that improve ease of use and the quality of the finished solution.

Practical benefits:
• a neater appearance without adhesive residue;
• no adhesive odor;
• the ability to fold and store precisely;
• increased resistance to temperature fluctuations;
• simplified quality control in production.

Possible limitations

Despite the advantages, the technology is still in the stage of active implementation.

Limitations include:
• the need to adapt equipment;
• higher initial cost;
• limited range of formats;
• dependence on coating activation technology.

However, as the scale of production increases, these factors are gradually leveled out.

What will change in the coming years

Glue-free packaging is expected to gradually expand its presence in the market.

Possible changes:
• emergence of new box and container formats;
• adaptation to different product categories;
• integration into mass production;
• increased demand from large retailers;
• reduced technology costs.

Most likely, such solutions will first gain a foothold in the B2B segment and then become available to a wider market. This is confirmed by global packaging trends.

Glue-free packaging is a logical step in the evolution of cardboard packaging. It combines several important aspects: eco-friendliness, technological advancement, convenience, and cost optimization.

These solutions help:
• simplify recycling;
• speed up production processes;
• reduce costs;
• improve packaging quality;
• adapt to modern market demands.

With increasing delivery, automation, and environmental demands, adhesive-free packaging has the potential to become the new industry standard and capture a significant market share in the coming years.
