Sustainable Adhesive Technology: Building Better Packaging for a Changing EPR Landscape

July 1, 2026

Sustainable adhesive technology is becoming an important part of packaging design as companies prepare for new EPR packaging requirements. Sustainable packaging adhesives can support recyclable packaging, while recycling-compatible adhesives and wash-off label adhesives may help materials separate more cleanly during recycling. Bio-based adhesives and low-carbon hot melt adhesive options can also reduce fossil-resource use and carbon impact. Together, these technologies give manufacturers practical ways to improve packaging sustainability without sacrificing bond strength or production performance.

Extended Producer Responsibility, or EPR, is changing how companies think about packaging. Producers are being asked to consider what happens to a package after it is used, including how it is collected, sorted, recycled, reused, or disposed of.

To learn more about current EPR legislation and updates, read our dedicated post here.

Why Sustainable Adhesive Technology Matters for EPR Packaging

EPR packaging laws usually look at the complete package rather than approving or rejecting one adhesive by itself.

That means a company should not simply look for a glue labeled “sustainable.” The adhesive must work with the package material, production process, distribution conditions, and intended end-of-life path.

Adhesive and coating choices may affect recyclability, material use, carbon impact, and possible EPR fees. Sustainable adhesive technology can support these goals in several ways, including:

• Helping packaging move through recycling more easily
• Reducing the amount of packaging material needed
• Lowering the carbon impact of the adhesive
• Supporting reusable or returnable packaging
• Reducing waste caused by poor bonds or damaged products

The right solution will depend on the application. A product that improves packaging sustainability in one package may not provide the same benefit in another.

Recycling-Compatible Adhesives Support Recyclable Packaging

Recycling-compatible adhesives are made to avoid creating major problems during recycling.

In plastic packaging, an adhesive may need to release from the main container during washing. In paper packaging, it may need to separate or break down without creating too much residue during repulping.

This is especially important for recyclable packaging because a package is more than its main material. Labels, inks, coatings, films, and adhesives can all affect the quality of the material recovered.

Sustainable packaging adhesives should therefore be evaluated as part of the entire package.

Recycling-compatible adhesives can help:

• Reduce contamination in recycled materials
• Improve the separation of labels and containers
• Support cleaner paper or plastic recovery
• Protect the quality of recycled material

These benefits can make sustainable adhesive technology an important part of design-for-recycling decisions.

Wash-Off Label Adhesives Help Labels Release

Wash-off label adhesives are one of the clearest examples of adhesive technology designed around recycling and reuse.

These products are expected to hold labels in place during filling, shipping, refrigeration, moisture exposure, and normal handling. During the proper washing process, however, the adhesive is designed to release.

H.B. Fuller offers wash-off label adhesives for glass and suitable PET applications that can be removed at lower wash temperatures and with less caustic solution. This can support recyclable packaging while also helping reduce water and energy use.

Wash-off label adhesives may be useful for:

• Returnable glass bottles
• PET beverage containers
• Bottle-washing operations
• Packaging designed for cleaner label separation

The complete application still needs to be tested. The bottle material, label stock, coating, water chemistry, wash temperature, and washing time can all affect performance.

Bio-Based Adhesives Can Reduce Fossil-Resource Use

Bio-based adhesives use some renewable or bio-circular ingredients in place of traditional fossil-derived materials.

This can lower the upstream carbon impact of the adhesive and reduce dependence on fossil resources. However, bio-based adhesives are not automatically recyclable or compostable.

Henkel offers hot melt products that use more renewable materials and are designed to perform similarly to traditional packaging adhesives. The company reports a 25% reduction in product-level carbon footprint for some of these products compared with older formulas.

These bio-based adhesives are also designed to support common packaging needs, including:

• Fast production speeds
• Strong final bonds
• Cold and freezer conditions
• Food-packaging requirements
• Existing hot melt equipment

For manufacturers, that can make the move toward sustainable adhesive technology easier because it may not require a complete production-line change.

Low-Carbon Hot Melt Adhesive Options Support Existing Operations

A low-carbon hot melt adhesive can reduce product-level carbon impact while still providing the bond performance needed for cases, cartons, and trays.

Henkel has developed low-carbon hot melt adhesive options that can run under similar temperatures and pressures as earlier products. This may allow facilities to make a change without major downtime or equipment adjustments.

That practical transition matters. A sustainable product is more likely to be used when it can fit into an existing operation without creating new production problems.

A low-carbon hot melt adhesive should still be tested for:

• Substrate compatibility
• Open and set time
• Application temperature
• Line speed
• Storage conditions
• Cold or heat resistance
• Final bond strength

Sustainable adhesive technology must work reliably in the real production environment, not only offer a lower carbon claim.

Sustainable Packaging Adhesives Can Reduce Material Use

Packaging sustainability is not only about changing raw materials. It can also mean using fewer materials.

High-mileage sustainable packaging adhesives may create the required bond with less adhesive. Lower-temperature products may reduce energy use. Palletizing adhesives may reduce the amount of stretch film, slip sheets, or corner boards needed to protect a load.

H.B. Fuller highlights several ways adhesives can support packaging sustainability, including:

• High-mileage hot melts
• Lower application temperatures
• Bio-based materials
• PET-labeling solutions
• Palletizing adhesives
• Fiber-based packaging features

These approaches support EPR packaging goals by reducing material use and waste at the source.

Recycling-compatible adhesives can improve end-of-life performance, while better adhesive application can prevent waste before the package ever reaches a recycling facility.

Reliable Bonds Are Part of Packaging Sustainability

An adhesive does not support packaging sustainability if it causes open cases, damaged products, rejected packages, or repeated line stoppages.

Poor adhesive performance can lead to:

• More packaging waste
• Product loss
• Additional transportation
• Rework and labor
• Higher adhesive use
• More downtime

That is why sustainable adhesive technology must be matched carefully to the application.

The best product should support environmental goals while also maintaining reliable bonds, clean application, and consistent production.

Biodegradable and Compostable Adhesives Need Careful Testing

Some bio-based adhesives are being developed for biodegradable or compostable packaging.

H.B. Fuller has tested bio-converting adhesive technology for fiber-based food packaging. In one paper-cup application, the adhesive ran on existing machinery and passed heat and leakage tests.

However, biodegradable or compostable claims must be specific. A biodegradable adhesive does not automatically make the complete package biodegradable. The paper, coating, ink, liner, and adhesive must all support the same end-of-life path.

The same rule applies to recyclable packaging. Every component needs to work with the intended recovery system.

Choosing Sustainable Adhesive Technology

When comparing sustainable packaging adhesives, manufacturers should look beyond one environmental claim.

A complete review should consider:

• The packaging material
• The intended recycling, reuse, or composting path
• The amount of adhesive used
• Application temperature
• Production speed
• Storage and shipping conditions
• Available test results
• Carbon and renewable-content claims
• Bond reliability

At AJ Adhesives, we help customers evaluate sustainable adhesive technology as part of the full packaging application. That may include comparing bio-based adhesives, testing recycling-compatible adhesives, reviewing wash-off label adhesives, lowering adhesive use, or selecting a low-carbon hot melt adhesive.

As EPR packaging programs continue to develop, the best approach is not to search for one universal “green” glue. It is to choose sustainable packaging adhesives that support reliable production and measurable packaging sustainability improvements.
