    Food safety starts with packaging. As direct-contact materials for food, plastic food wrap and storage bags must meet rigorous hygiene standards to protect consumers’ health and preserve food freshness. To fully control product quality at the source and safeguard food safety, our company has built a high-spec Class 100,000 cleanroom dedicated to the full hygienic production of food-grade plastic wrap and food storage bags. Supported by strict manufacturing standards, we deliver pure, safe and reliable food packaging solutions


Stringent Cleanroom Specifications Aligned with Global & Domestic Standards.

    Our Class 100,000 cleanroom complies with the international ISO 14644-1 cleanroom standard, as well as China’s national specifications: GB/T 23887 General Good Manufacturing Practice for Food Packaging Manufacturers and GB 4806.7 Safety Standards for Plastic Materials in Contact with Food. This classification represents a qualified premium hygiene standard for manufacturing food wrap and storage bags.
    Equipped with complete air purification, constant temperature & humidity control and intelligent fresh air filtration systems, the workshop uses multi-stage filters to continuously remove airborne particles, microorganisms and contaminants. Key indicators including particle concentration, settling bacteria and airborne bacteria are closely monitored to eliminate dust, hair, plastic debris and bacterial pollution, effectively avoiding defects such as black spots, foreign particles and hygiene non-compliance. Zoned enclosed production management further reinforces consistent cleanliness for every finished product.


Customized Clean Production for Food-Grade Freshness Packaging

    Tailored to the unique requirements of food-contact plastic films, all core production procedures — film blowing, traction, slitting, bag making and inner sealing of finished goods — are carried out within the Class 100,000 clean zone. Supporting processes including raw material unpacking and outer packaging are arranged in separate independent zones to realize fully standardized hygienic manufacturing.

    Class 100,000 cleanliness level is the widely recognized compliant premium standard in the food plastic film packaging industry, perfectly suited for non-sterile food-contact packaging production. Our food wrap and storage bags satisfy diverse application scenarios including household daily use, supermarket retail, catering services and food processing factories, while fully guaranteeing food contact safety.


End-to-End Quality Control System for Consistent Premium Quality

    A clean production environment lays the foundation for quality, while a comprehensive management system guarantees stable standards. Beyond our high-grade cleanroom, we implement full-chain quality control covering raw material intake through finished product delivery:

  1.     Strict Raw Material Selection: Only food-grade PE resin complying with national food contact safety standards is adopted to eliminate harmful substances and impurities from the very beginning.

  2.     Regular Equipment Sanitation: All production machinery undergoes thorough scheduled cleaning and disinfection to prevent carbon buildup and chemical precipitation contamination.

  3.     Standardized Staff Management: All operators follow strict cleanroom protocols, wearing specialized cleanroom uniforms and completing air shower sanitization plus hand disinfection before entering production areas.

  4.     Routine Sampling Testing: Daily sampling inspections are performed on both workshop environmental conditions and finished products, with complete test records retained to ensure every batch meets cleanliness and safety benchmarks.


Hygienic Manufacturing Strength Delivers Trustworthy Quality

    From conventional manufacturing to hygienic intelligent production, we always prioritize food safety and adhere to rigid quality benchmarks. The launch of our Class 100,000 cleanroom upgrades our production capacity and embodies our quality commitment to global buyers and end consumers.

    Moving forward, we will continuously refine our hygienic production system and quality control workflows, supplying odor-free, impurity-free and fully compliant food wrap and storage bags to the market. We strive to protect food safety for all users and provide stable, high-quality customized food packaging supply services for worldwide partners.
