α-Separating Cartridge: A Plastic-Saving Breakthrough and the Adhesive Industry’s Green Upgrade
2025-04-18

Single-use plastic cartridges have long burdened our planet. Meet the α-Separating Cartridge—an innovative paper-based refill system that slashes plastic waste without changing the way you work.


Cut Plastic at the Source
Made from high-strength, biodegradable paperboard, the α-Separating Cartridge replaces disposable plastic tubes entirely. Each reuse keeps another cartridge out of landfills—an immediate win for the environment.

Drop-In Compatibility, Zero Learning Curve
Engineered to fit every standard caulking gun, the cartridge installs in seconds. Pros and DIYers alike can keep their current workflow—only the waste disappears.

Five-Times Reuse, Five-Times Value
Lab tests confirm one α-Separating Cartridge reliably dispenses five soft refill pouches. That’s up to 80 % less material cost and disposal expense compared with single-use plastic.

Smart Soft-Pouch Refills
Each aluminum-lined pouch prevents skinning and bubbling in silicones and MS polymers, delivering a cleaner bead and a smoother finish.


The α-Separating Cartridge is more than a greener alternative—it’s the new benchmark for sustainable dispensing. Switch today and turn every job into a vote for a cleaner future.
