DJPACK promotes certified MAP tray sealing for cheese packaging

By AI, Created 10:08 AM UTC, May 19, 2026, /AGP/ – Wenzhou Dajiang Vacuum Packaging Machinery Co., Ltd. is highlighting optimized modified atmosphere packaging tray sealers for cheese, aiming to extend shelf life, protect texture and reduce spoilage. The company says its machines carry CE, MET and TUV certifications and are designed for different cheese types and high-output dairy lines.

Why it matters: - Cheese is highly sensitive to oxidation, dehydration and microbial spoilage, which makes packaging a major factor in shelf life and product quality. - Modified atmosphere packaging can help dairy producers keep cheese fresher longer without relying on heavy preservatives. - Better tray sealing can also reduce food waste and support clean-label product trends.

What happened: - Wenzhou Dajiang Vacuum Packaging Machinery Co., Ltd. is promoting optimized certified MAP tray sealing solutions for cheese. - The company says the systems are designed to preserve texture, flavor and appearance through longer supply chains. - DJPACK is the company’s brand for tray sealing and vacuum packaging equipment. - A full product overview is available in the company’s announcement.

The details: - The machines use a gas flush system that replaces oxygen inside the tray with a calibrated mix of carbon dioxide and nitrogen. - The company says the equipment lowers residual oxygen by optimizing vacuum pump integration and gas displacement timing. - The systems are built for high-output packaging lines while aiming to limit energy use. - DJPACK says the tray sealers are certified to CE, MET and TUV standards. - CE certification covers European health, safety and environmental requirements. - MET and TUV certification indicate independent laboratory testing for safety and performance. - The company says the machines can be used by dairy facilities in Canada and Australia with regulatory alignment in mind. - The systems are designed for different cheese formats, including hard blocks, soft cheeses and shredded blends. - The DJL series includes an interface for switching between product-specific recipes. - The company says operators can adjust tray dimensions, sealing pressure and gas ratios based on moisture and density. - Production hubs in Wenzhou and Nanjing support that customization work.

Between the lines: - The pitch is not just about packaging machinery; it is about helping cheese producers protect premium quality while moving product farther and faster. - Certification is being used as a sales argument as much as a compliance marker, especially for buyers in regulated export markets. - The emphasis on recipes and customization suggests the company is targeting processors handling multiple cheese SKUs on the same line.

What’s next: - Wenzhou Dajiang is positioning MAP tray sealing as a long-term platform for global dairy customers as cheese demand expands in Asia, North America and other export markets. - The company says its focus remains on quality-first manufacturing, continuous innovation and service support for food processors.
