Custom Brown Kraft Paper Bags for High-Strength Furnace Lining Materials
The kraft paper open-mouth bag, also known as an open-top bag or open-mouth paper bag, is manufactured from high-strength kraft paper through processes including bag making, cutting, and bottom reinforcement. This creates an open-type packaging container ideal for various industrial applications.
Featuring an open-mouth design that eliminates complex valve structures, these bags allow for easy and efficient filling, making them perfectly suited for automated filling production lines.
Open bag mouth design eliminates precise alignment requirements, enabling swift material loading and perfect compatibility with high-speed automated packaging lines.
Multi-layer kraft paper lamination provides excellent tensile strength and tear resistance, supporting weights from 20kg to 50kg with options for higher capacities.
Optional PE inner membrane lamination or surface waterproof coating creates dual protective barriers against external moisture, dust, and impurities.
Available in natural brown or white kraft paper with multi-color flexible plate printing for clear branding, logos, and product specifications.
100% recyclable and reusable kraft paper core material complies with international environmental standards including EU RoHS and REACH requirements.
