The company has established a comprehensive four-level quality control system spanning “incoming materials – production process – finished product outgoing,” ensuring product safety and consistent quality through stringent standards. The Incoming Quality Control (IQC) implements full-item testing, screening 18 indicators including basis weight, microbiology, and heavy metals for plant fibers, functional liquids, packaging materials, and biodegradable raw materials, preventing non-conforming items from entering the production line at the source.

• The In-Process Quality Control (IPQC) conducts hourly inspections and sampling, providing real-time monitoring of four critical nodes: composite forming, cutting and folding, packaging, and sterilization. This ensures core process parameters meet standards, such as moisture uniformity deviation ≤ ±5%, dimensional accuracy error ≤ ±1mm, and seal peel strength ≥ 30N/15mm.

• The Outgoing Quality Control (OQC) performs batch-wise full inspection, covering appearance, weight, microbiology, heavy metals, skin irritation, and special performance characteristics (e.g., biodegradation rate, bactericidal rate). The sampling ratio is 0.5%–1%, and packaging drop and stacking tests are completed to guarantee final product quality.

• A supporting “one batch, one code” full-process traceability system** has been established, enabling a 24-hour post-sales response and a 48-hour quality rectification closed loop. Through monthly data review and continuous improvement, the company strictly controls the product non-conformance rate below 0.1%**, solidifying its quality moat with systematic quality control capabilities.
