Workshop Environment

The cleanroom is designed and built according to a 100,000-level GMP standard. The design fully considers the air volume, fresh air purification, positive and negative pressure differentials, air exchange frequency, workshop illumination, and other GMP design specifications.

Process Design
Emission Reduction
Workshop Environment

The factory design strictly follows food safety regulations, considering the required human flow, logistics, equipment, and on-site storage for each production process of paper cups and paper straws, resulting in a U-shaped factory layout.

Quality Control System

From raw materials to finished products, every step is recorded and traceable.
We have established a comprehensive quality control system covering raw materials → production process → finished product dispatch, strictly following both domestic and international food-grade standards to ensure every batch of products is safe, qualified, and stable:

  • Complete Quality Control System

    Established records for inbound/outbound goods, raw material usage, production process, and testing.

  • Sampling System

    All product batches have a sample retention system, archived for 2 years. Video surveillance records are automatically retained for 6 months.

  • Retrospective Training

    Annual traceability drills are conducted, ensuring material balance can be verified within 2 hours with deviations less than 5%.

Testing Systems
Before shipment, products undergo a systematic testing procedure to ensure safety in practical scenarios
Paper Cup Testing
Odor group evaluations: empty cup test, hot water test, ink volatilization test. Liquid performance tests: leakage test, hot/cold water test, coffee oil-water test. Lid performance tests (14 items): including rotation, shaking, dropping, lid lifting, static sealing, walking simulation, etc. Seal membrane pressure test, cup rim stiffness, thickness, weight, and high/low-temperature resistance.
Straw Testing
Stiffness test, water immersion test, tear test, odor test. Automated visual inspection system to detect breakage, missing parts, misalignment, abnormal length, etc.
Printing and Pattern Testing
Color difference, printing misalignment, color fading.Pattern integrity, ink durability, and print dot precision control.

  • Food-Grade Management under the HACCP System

    We not only focus on innovation but also have the system capability to convert technological achievements into mass-produced products.
    Under the HACCP system, we break down the production of paper cup products into 43 standardized process steps, setting:

    1 CCP (Critical Control Point)

    4 OPRP (Operational Prerequisite Program) critical operational control points This ensures that key food contact processes are controllable, predictable, and adjustable in terms of hygiene and safety.

  • Quality Inspection Team

    Our quality inspectors have an average of 10 years of industry experience and maintain a rigorous attitude throughout the entire process.
    The quality control team works closely with the R&D and production teams, engaging in risk assessments from the design stage.

    They strictly follow process documents and testing standards to ensure operational consistency.

    Our quality inspectors have an average of 10+ years of experience and are familiar with various problem-solving methods.

  • Commitment

    We solemnly promise to offer returns and exchanges for quality issues and actively respond to after-sales concerns:

    Support returns and exchanges within the warranty period for product quality issues.

    100% inspection of all product batches before shipment.

    Provide corresponding external testing reports for products.

    Offer a fast-response business + quality inspection coordination mechanism.
