As environmental awareness grows and plastic regulations tighten worldwide, the packaging industry is shifting toward sustainable alternatives. Traditional plastic cartridges used for silicone sealants, glass adhesives, and other building chemicals have long been an environmental concern. In Germany alone, approximately 100 million adhesive and sealant cartridges are produced each year for the DIY sector, generating around 5,000 tonnes of plastic waste annually. What makes the problem worse is that even when empty, conventional plastic cartridges are nearly impossible to recycle due to residual product contamination, and they can take up to 500 years to break down in landfills.
Recognizing this urgent need, our company is proud to introduce the Paper Cartridge – a new-generation packaging solution designed specifically for sealants, silicones, and adhesives. By significantly reducing plastic content while maintaining full compatibility with existing filling machines and standard caulking guns, our paper cartridge offers a seamless and immediate transition to eco-friendly packaging.
Less Plastic, Lower Carbon Footprint
Our paper cartridge is engineered with sustainability at its core. The cartridge body is made primarily from paper-based materials, reducing plastic usage by approximately 80% compared to a conventional all-plastic cartridge. This dramatic reduction in plastic is accompanied by a substantial drop in carbon emissions: independent testing has shown that paper cartridge manufacturing can lower CO2 emissions by 53% compared to traditional polyethylene cartridges.
These environmental benefits are already being recognized by major industry players. In autumn 2025, Henkel launched its own paper-based cartridge under the Pattex brand, cutting non-recyclable waste by up to 73% and using at least 49% recycled plastic for the non-paper components. Such innovations are driving strong market growth. The global eco-friendly packaging market was valued at over US$217 billion in 2024 and is expected to reach nearly US$395 billion by 2031. More than 60 countries and regions have implemented mandatory plastic restriction policies, further accelerating the shift to paper-based packaging.
Compatible, Reliable, and Brand-Friendly
Despite its paper construction, the paper cartridge works with your existing filling equipment – no changes to production lines are required. It also fits perfectly into all standard caulking guns, allowing end users to continue working exactly as before. Sealants and adhesives packaged in paper cartridge follow the same formulations, ensuring product performance remains unchanged.
To protect product integrity, the cartridge incorporates a high-barrier layer (available as an aluminum foil liner or an eco-friendly coating) that effectively prevents solvent evaporation and moisture ingress, guaranteeing shelf life during storage and transport.
In addition, the paper cartridge can be easily customized with high-quality labels. Whether you need full-color branding, product instructions, or barcodes, labels adhere cleanly to the smooth paper surface, providing a professional and attractive finish. This makes it simple for your brand to stand out on store shelves without the need for direct printing on the cartridge.
An Industry-Wide Movement
The paper cartridge is not a distant concept – it is already gaining industry recognition. At the International Hardware Fair in Cologne, a paper cartridge solution received two awards: the Iron Award 2024 and the BHB Industry Award "Best of Eco 2024", with the jury praising its "very high degree of waste avoidance, the courage to break new ground, and a high degree of innovation." Leading packaging companies are also offering paper cartridges in standard fill volumes such as 300 ml, 600 ml, 800 ml and 1000 ml, confirming that this technology is ready for widespread adoption.
Conclusion
The transition to sustainable sealant packaging is no longer optional – it is an urgent necessity driven by regulations, customer expectations, and corporate responsibility. Paper cartridge offers a practical, proven, and impactful solution that reduces plastic waste, lowers carbon emissions, and works with your existing operations.
