The core of material selection lies in "compatibility" — meeting process requirements while balancing quality and cost. After multiple rounds of bamboo species comparison and process testing, we ultimately select 3–5-year-old moso bamboo and giant bamboo as core raw materials, a well-considered choice. In terms of fiber properties, they feature high fiber content, excellent toughness, uniform fiber length and moderate aspect ratio, perfectly suited for the production of drawstring bags and flat bags. This effectively ensures load-bearing capacity and prevents damage or tearing during use.
More importantly, moso bamboo and giant bamboo are highly compatible with the wet-laid forming process, the optimal technology for large-scale mass production of bamboo fiber degradable products. It enables uniform fiber dispersion, delivering base materials with stable grammage and a delicate texture that fully meets the quality standards of drawstring and flat bags. Compared with other bamboo varieties, these two types have a moderate growth cycle, high yield and reasonable procurement costs. They not only satisfy cost control for mass production but also avoid supply chain risks caused by raw material shortages, ensuring stable production.
With premium raw materials selected, pretreatment becomes the key to unlocking bamboo fiber potential and serves as our core competitive advantage over traditional processing. Conventional methods rely heavily on strong chemical alkali degumming. Though effective for rapid impurity removal, this process damages the natural properties of fibers, resulting in rough, brittle finished products and large volumes of polluted wastewater. It fails to meet EU environmental standards and cannot access high-end markets.
Abandoning the drawbacks of traditional techniques, we adopt a combined process of bio-enzymatic degumming + physical mechanical fiberization to achieve simultaneous upgrades in environmental performance and product quality. The bio-enzymatic degumming process uses a compound system of cellulase and hemicellulase to precisely decompose impurities under mild conditions, without strong alkalis or acids. This fully preserves the natural toughness of bamboo fibers and ensures discharge compliance, fully meeting EU environmental protection and food-contact grade standards. Subsequent physical mechanical fiberization further refines the fiber structure and removes residual impurities, creating a stable foundation for downstream processing.
To accommodate diverse application scenarios, softening and modification serve as a critical finishing step in pretreatment. By adding food-grade plant-based softeners alongside constant-temperature stirring and low-temperature shaping, we significantly enhance the flexibility and load-bearing capacity of bamboo fibers, breaking the stereotype of bamboo fiber products being rough and fragile. Modified bamboo fibers offer a soft, premium texture, suitable not only for daily-use drawstring and flat bags but also for high-touch applications such as gaskets, realizing true multi-purpose material utilization.
Every step from material sourcing to pretreatment determines product competitiveness. The targeted selection of 3–5-year-old moso and giant bamboo resolves the core conflict between quality and cost. Bio-enzymatic degumming upholds environmental standards while guaranteeing quality. Softening and modification expand application boundaries to meet diversified demands. As a manufacturer of eco-friendly products, we firmly believe that only strict control over upstream processes can produce bamboo fiber degradable products that comply with global environmental regulations while delivering practicality and high-end quality, helping enterprises thrive in the green market.
