Dedicated to Purity, Guardian of Health: Rizhao Wanjia International SCM's Food-Grade Cleanroom
Rizhao Wanjia International SCM Co., Ltd. has invested in building a high-standard cleanroom, specifically engineered for the production of food-grade plastic products like Pe Gloves and cling film. This facility integrates a high-efficiency air filtration system, strict air pressure control, and a comprehensive microorganism monitoring regime. It ensures every step, from raw material to finished product, occurs in a pristine, dust-free, and sterile environment. Grounded in technology and guided by rigor, we provide a safe, reliable, and trustworthy manufacturing guarantee for your products.
1.A Barrier of Purity Forged by Technology: The Comprehensive Hardware System
The cleanroom at Rizhao Wanjia is a sealed ecosystem built with cutting-edge technology. Structurally, it features smooth, corrosion-resistant metal panels and seamless rounded corners, fundamentally eliminating dust accumulation and cleaning dead angles. The "heart" of the room—the air purification system—utilizes primary, intermediate, and high-efficiency three-stage filtration. At the final stage, HEPA filters covering the entire area ensure the removal of over 99.97% of airborne particles ≥0.3μm, achieving ISO Class 7 (10,000 Class) or higher standards. Furthermore, a precise HVAC system maintains constant temperature and humidity, while a stable positive air pressure gradient acts as an invisible shield, effectively preventing the ingress of contaminated outside air. This creates a stable, pure environment akin to a "sterile laboratory" for producing food-grade PE gloves and cling film.
2.The Art of Meticulous Process: A Closed-Loop Purification System for Personnel and Materials
The most advanced facilities require flawless processes to activate them. At Rizhao Wanjia, we recognize that people are the most significant dynamic source of contamination. Therefore, we have established an extremely rigorous purification protocol. All personnel must follow a standardized procedure: changing shoes → first-stage gowning → hand washing and disinfection → donning dedicated full-body cleanroom suits → a 360-degree high-pressure air shower in the airlock. This ensures even the tiniest particles are barred from the production area. For materials, we have designated independent unpacking and buffer zones. All raw materials and packaging must undergo strict wipe-down disinfection or air shower purification before entering the core production area through interlocked pass-through windows. These interlocking steps form an impeccable closed-loop purification system, guaranteeing that from the very first process, every cubic inch of air and every surface the product contacts is in a controlled state of cleanliness.
3. Guardianship Beyond the Naked Eye: Round-the-Clock Environmental Monitoring and Quality Assurance
Cleanliness is not just about construction but sustained vigilance. Our cleanroom is equipped with an intelligent monitoring network that exceeds conventional standards. Real-time differential pressure sensors and temperature/humidity displays act like "environmental vital sign monitors," ensuring physical parameters are always optimal. More critically, we have implemented an online airborne particle monitoring system that performs continuous, real-time counting and analysis of airborne particles, feeding data directly to a central control system. For microbiological control, we regularly use settle plates and contact plates to sample key areas, such as equipment discharge ports and workstations. All data is meticulously recorded and archived, creating a traceable quality record that verifies every roll of cling film and every PE glove is born from a scientifically validated pure environment.
4. Empowering Your Future: Custom Pure Solutions for High-End Food Packaging
The value of Rizhao Wanjia International Supply Chain's cleanroom extends far beyond a mere production space. It embodies our highest commitment to food safety and our profound understanding of protecting our clients' brand reputation. Food-grade PE gloves and cling film produced in this environment drastically eliminate the risk of foreign matter residue and microbial contamination caused by an unclean production environment, leading to a revolutionary improvement in product purity and consistency. This not only significantly extends the shelf life of the end-user's food products but also endows your brand with impeccable safety credentials. We are committed to making this cleanroom your most reliable "extended production base." Through international standards and professional, meticulous management, we infuse a pure gene into your products, working together to safeguard the health of millions of consumers.
