Surface treatment to prevent staining and accelerate the drying process

Dishwasher trays, baskets, racks, and food storage containers often retain water droplets after washing, resulting in longer drying times and a less satisfactory user experience. Residual water can also leave visible spots on glasses, dishes, and plastic surfaces, making items appear less clean even when they have been thoroughly washed.

Persistent staining from colored beverages and foods can significantly reduce the visual appeal of reusable plastic packaging. Stains from drinks, ketchup, curries, and other highly pigmented products often limit the number of times cups, bowls, and containers are reused before consumers choose to replace them.

Delta Engineering’s plasma treatment systems create durable surface properties that improve water repellence, prevent staining, and enhance cleanability. Moreover, the effect remains effective over multiple reuse cycles, helping reusable packaging maintain its appearance and performance.

Plasma treatment

Unlike conventional surface treatments that can lose effectiveness over time, our deep-vacuum plasma process uses functional gases to create durable, long-lasting surface properties. This enables reusable cups, bowls, and packaging to maintain their desired performance over multiple reuse cycles, supporting long-term product effectiveness and sustainability.
