Countries around the world have successively introduced regulations regarding plastic reduction

in packaging, mandatory recycling, and Extended Producer Responsibility (EPR) schemes.
The pace of packaging upgrades in the construction sealant and nail-free adhesive industries is accelerating.
Traditional disposable plastic cartridges are difficult to recycle and entail high carbon emissions;
in contrast, composite paper cartridges—offering advantages such as recyclability, a low carbon footprint,

and reduced plastic usage—are increasingly becoming the mainstream green packaging solution for

building material exporters seeking to meet overseas compliance requirements.

Which countries have introduced relevant policies?

EU's Packaging and Packaging Waste Regulation has been finalized, mandating that all packaging be recyclable by 2030.

It strictly controls the total volume of packaging waste, mandates higher proportions of recycled content, and imposes stricter

environmental obligations and higher Extended Producer Responsibility (EPR) costs on hard-to-recycle plastic packaging.

- United Kingdom: Imposes a plastic packaging tax; companies must pay high levies if packaging contains

less than 30% recycledplastic, compelling manufacturers to reduce the use of virgin plastic.

- California, USA: Implementing stricter plastic control legislation starting in 2026, setting reduction

targets for industrial plastic waste and single-use plastic packaging.

- South Korea and India: Have successively introduced new plastic waste regulations, mandating

increased use of recycled materials in packaging and tightening market access restrictions for non-recyclable plastics.

- Various Southeast Asian countries: Gradually implementing plastic waste controls and restricting the import

of hard-to-degrade plastics; green packaging has become an advantage for market entry.

Comprehensive Comparison of Environmental Performance

1. Material Sourcing and Plastic Reduction
Traditional plastic cartridges are primarily made from petroleum-based virgin plastic, a non-renewable resource.
The body of the composite paper cartridge is made from FSC-certified kraft paper, significantly reducing plastic usage.

Body can enter the waste paper recycling stream and be repulped for reuse, unaffected by small amount of residual sealant inside.

2. Carbon Emission Differences
Plastic cartridges involve high energy consumption throughout the entire process, from petroleum refining to extrusion molding.

Composite paper cartridges utilize a lower-carbon production process; CO2 emissions during production are reduced by over 50% compared

to plastic cartridges, helping brands lower their product carbon footprint and meet the carbon-neutral procurement requirements of overseas clients.

3. Recycling and Disposal

- Plastic Cartridges: Residual sealant adheres to the plastic surface, making recycling difficult after sorting;

the recovery value is extremely low, and most end up as waste.
- Composite Paper Cartridges: The paper shell can be easily peeled off for recycling. During the mechanical

pulping process at paper mills, impurities are filtered out from the paper fibers, ensuring a mature and stable recycling pathway.

4. Performance Assurance
Many enterprises are concerned about the sealing integrity of paper cartridges. Modern paper cartridges feature a multi-layer composite

paper and industrial-grade liner structure, combined with a tinplate base or plastic components. 

They offer moisture and leak resistance, are compatible with standard caulking guns without altering application habits,

and fully meet the filling and storage requirements for nail-free adhesives, silicone sealants, and structural adhesives.

They also support custom sizing and brand logo printing.
