--- Comprehensive Product Range ---
• High-Quality Composite Vacuum Bags:
At Topclean, our composite vacuum bags are engineered for maximum protection and performance in demanding environments. Each bag features a multi-layer structure: a 20–25% outer layer of virgin PET for strength and printability, a 10–15% middle barrier layer of pure aluminum foil (or EVOH) for superior oxygen and moisture resistance, and a 60–70% inner layer of LLDPE/mPE blend for excellent heat-sealing and flexibility. These bags are specifically designed for high-precision electronics, pharmaceuticals, and food products requiring extended shelf life. A real-world example is our collaboration with a Tier-1 semiconductor supplier in South Korea, who faced frequent oxidation issues with their microchip components during international shipping. After switching to Topclean’s custom-designed PET/Al/PE composite vacuum bags, they reported a 98% reduction in post-delivery defects. The bags’ consistent heat-seal strength (>50N), puncture resistance (>5N), and near-zero defect rate (<0.1%) ensured complete protection against humidity and static. Furthermore, the solvent-free adhesive process complies with FDA and EU 10/2011 standards, making it ideal for sensitive applications. This case highlights how Topclean’s advanced material science and full in-house production enable us to deliver not just packaging, but mission-critical protection solutions tailored to global industry demands.
• Versatile PE and Aluminum Foil Bags:
Our PE and aluminum foil bags are crafted to meet the evolving needs of industries ranging from food and pharma to automotive and new energy. For instance, a major Chinese organic food exporter based in Hangzhou was struggling with inconsistent sealing performance and contamination risks when using standard PE bags for dried fruit and nut packaging. They partnered with Topclean to develop a custom LLDPE/PE blend film with enhanced anti-static and moisture-barrier properties. The result? A 40% improvement in shelf life and zero contamination incidents over six months. Similarly, in the photovoltaic sector, a leading solar panel manufacturer in Jiangsu required moisture-proof packaging for silicon wafers during transport. We delivered a custom aluminum foil bag with a 12μm virgin PET outer layer, 10μm pure aluminum foil, and a food-grade PE inner seal—fully compliant with ISO 22000 and ISO 9001. This solution reduced moisture ingress by 99.7% compared to previous packaging, significantly lowering yield loss. With over 200 employees and a 33,000 sqm factory in Kunshan, Topclean leverages its vertically integrated production line—including blow molding, printing, lamination, and automated bag-making—to ensure rapid customization, cost efficiency, and scalability. Whether it’s standard PE bags for retail or specialized aluminum foil bags for high-tech industries, Topclean delivers reliable, adaptable, and future-ready packaging solutions.

• ISO Certified Manufacturing Processes:
Topclean’s unwavering dedication to quality is rooted in its fully integrated, ISO-certified manufacturing ecosystem. From raw material sourcing to final inspection, every stage follows closed-loop ISO 9001 quality management processes. Unlike many competitors who rely on third-party sampling (typically 10% inspection with defect rates of 1–2%), Topclean conducts 100% in-process testing using advanced equipment such as multi-functional tensile testers, 5-segment heat-sealing testers, and high-temperature autoclaves. For example, during a recent audit for a European medical device client, our lab demonstrated a defect rate of just 0.08% across 10,000 vacuum bags tested—far below industry averages. Our proprietary solvent-free lamination process eliminates harmful VOC emissions, aligning with EU Green Deal and China’s dual carbon goals. In 2023, we invested over 5 million RMB in R&D to optimize barrier layers, resulting in a 15% reduction in material thickness without compromising performance—a breakthrough that lowered environmental impact while maintaining compliance with ISO 22000 and Argentine Certificate of Free Sale. Moreover, our use of virgin PET (12–15μm) and pure aluminum foil ensures no recycled content, guaranteeing purity and safety. This level of control and transparency has earned Topclean the AAA Certificate and solidified trust among clients in regulated sectors like pharmaceuticals and aerospace. By combining rigorous standards, sustainable innovation, and full production transparency, Topclean doesn’t just manufacture packaging—it sets the benchmark for responsible, high-performance soft packaging globally.
--- Global Reach and Customer Satisfaction ---
• Exporting to Over 50 Countries:
Topclean’s global footprint spans over 50 countries and regions, including key markets in Europe, North America, Southeast Asia, and Latin America. One standout success story involves a premium coffee roaster in Germany, which needed a sustainable, high-barrier packaging solution for single-origin beans. After evaluating multiple suppliers, they selected Topclean’s custom composite vacuum bag with a light-blocking PET/Al/PE structure. The bags not only preserved flavor integrity for up to 18 months but also reduced CO₂ emissions by 22% per unit due to thinner, lighter materials. Within one year, the German brand saw a 35% increase in export orders, attributing much of the growth to Topclean’s reliable, eco-conscious packaging. Another milestone was our partnership with a U.S.-based battery manufacturer producing lithium-ion cells for electric vehicles. Their strict requirements for foreign matter control, anti-static properties, and moisture resistance were met through Topclean’s shielded composite bags with conductive layers and ultra-clean production environment. This collaboration led to a three-year contract worth $8.5 million annually. With an annual export value of 50 million USD and a domestic sales volume of 200 million RMB, Topclean continues to expand its reach through strategic partnerships, technical support, and localized market analysis. Our factory in Kunshan, equipped with 30+ automated production lines and a dedicated R&D team, enables fast turnaround times and agile responses to global demand. Whether serving small startups or multinational corporations, Topclean delivers consistent quality, timely delivery, and long-term value—proving that true global success begins with local excellence.
