Colored multi-layer kraft paper bags are manufactured using high-strength pure wood pulp kraft paper as the base material. Through a multi-layer composite process combined with environmentally friendly colored printing techniques, these bags provide either open-style or custom packaging containers that successfully integrate the toughness and durability of kraft paper with enhanced visual recognition.

• Appearance and Strength Combined: Eco-friendly water-based colored inks provide vibrant, uniform colors that resist fading and smudging. Customizable color patterns, brand logos, and product specifications enhance brand recognition.
