Automated surface coating and treatment solutions for food storage containers

Improving hygiene, durability, and recyclability with glass coating and plasma treatment

Food storage containers face strict hygiene, appearance, and sustainability requirements. Plastic containers are lightweight and cost-efficient, but prone to staining, odor absorption, and reduced reusability after contact with oily or acidic foods.

Delta Engineering, together with Isytech, provides plasma-based coating and treatment technologies that eliminate these issues.

Our systems apply anti-staining glass coatings and plasma treatments that improve cleanability, prevent discoloration, and support food-safe, recyclable, multi-use packaging.

Glass coating

Plasma treatment

Glass coating

Our glass coating technology creates a thin, food-safe silicon oxide layer inside plastic containers. It prevents direct contact between food and plastic and protects against staining from all types of food, including heavily spiced curry and chili dishes, as well as high-fat products. Our glass coating keeps packaging clear, hygienic, and reusable, even after repeated washing and microwaving.

Plasma treatment

Our plasma treatment modifies the container surface to effectively prevent staining while providing a droplet-free drying effect, preventing water droplets from forming on the treated surface.

Smart surface innovation

Reliable food packaging performance

Together with Isytech, we combine decades of plasma treatment expertise to develop next-generation surface treatments that keep containers cleaner, safer, and more durable with minimal energy use and zero harmful chemicals.

Flexible automation

Integrated into any production line

Our systems are available in manual, semi-automatic, or fully automated configurations. Compact and modular by design, they integrate seamlessly with existing conveying and packaging lines.

Validated food safety

Meeting the highest hygiene standards

All coatings and treatments are tested and validated, ensuring compliance with food-contact and recycling regulations.

Reliable partnership

Global support and long-term reliability

Every Delta Engineering and Isytech system is developed, built, and serviced by our own teams, guaranteeing consistent performance, expert support, and lasting dependability.

Enhancing packaging performance through advanced surface treatment

Every detail matters in food and beverage packaging. Delta Engineering’s automation systems for glass coating and plasma treatment ensure consistent protection against staining and discoloration, combining efficiency, food safety, and sustainability in one process.
