Kraft paperboard cartridges for sealant packaging are industrial-grade, eco-friendly tubes designed for silicone and acrylic adhesive dispensing in construction applications—not ammunition casings, printer supplies, or food containers. These caulking gun-compatible tubes serve as a sustainable alternative to plastic cartridges, meeting the growing demand for recyclable packaging solutions. Since 1987, New Chang-An has pioneered biodegradable sealant packaging that aligns with green building certification requirements.
Crafted with precision from high-quality paperboard materials, our cartridges offer exceptional durability, strength, and resistance to wear and tear, making them ideal for use in harsh environments and rigorous operating conditions.
Whether you're looking for a reliable solution for packaging, storing, or transporting your goods, our Paperboard Cartridges are the perfect choice. With their sturdy construction and versatile design, they can easily accommodate a variety of products, including powders, granules, liquids, and more.

Our spiral wound kraft tubes deliver equivalent strength to HDPE plastic through multi-layer construction, while reducing transportation weight by 35% and logistics costs by 40%. The biodegradable barrier coating provides 98% moisture resistance without compromising eco-friendly credentials—addressing the primary concern about paperboard durability in industrial environments.
Layer Count (3-5 Layers): More layers equal higher crush resistance. Our 5-layer structure withstands >500psi compression pressure, matching HDPE plastic cartridge performance standards for standard caulking gun applications.
Paperboard Weight (300-400gsm): Higher gram-per-square-meter ratings indicate thicker walls. 350gsm prevents acidic silicone penetration, while 400gsm suits high-viscosity MS polymer sealants and polyurethane foam formulations.
Spiral Angle (45°/60°): The 45° winding angle optimizes strength-to-flexibility balance, ensuring smooth dispensing with standard 310ml caulking guns without tube collapse during adhesive application.
Moisture Barrier: Water-based PE coating (food-contact compliant) delivers 98% moisture protection while maintaining 100% biodegradability—a critical innovation for sustainable construction packaging.
