Advanced plasma barrier technology for longer shelf life and regulatory compliance

Plastic bottles, containers, L-ring drums, and pails increasingly face stricter requirements for permeation, shelf life, and sustainability. Oxygen ingress, aroma loss, solvent compatibility, or migration can compromise product quality and lead to regulatory non-compliance. Traditional barrier solutions often rely on multi-layer or fluorinated materials that face growing restrictions.

Delta Engineering’s plasma coating systems apply an ultra-thin barrier layer inside rigid plastic packaging, improving product protection while keeping materials recyclable and future-proof.

Plasma coating for solvent-based liquids

Our plasma coating systems apply a uniform, ultra-thin barrier layer inside plastic bottles, containers, and pails. When applied to HDPE packaging, the coating reduces solvent permeation, extends shelf life, prevents migration between the product and the packaging, and complies with applicable regulations. Applications include pesticides, herbicides, paints, technical coatings, automotive care, and cleaning products.

Plasma coating for food and beverage

Our plasma coating systems provide PET and fiber bottles with an ultra-thin internal barrier layer to significantly improve oxygen, carbon dioxide, and water vapor barrier performance. The result is longer product shelf life, better product protection, and improved packaging performance. For instance, carbonation is retained in soft drinks and beer, and oxygen-sensitive products such as fruit juices and sauces are protected against oxidation. In addition, the plasma coating minimizes migration between the packaging and the product, preserving the product’s original flavor.
THE BEST CHOICE FOR BARRIER COATING OF PLASTIC PACKAGING

Protection

Improves barrier performance of monolayer plastic packaging against oxygen, solvents, and aroma loss.

Compliance

Meets strict regulatory limits for different types of products.

Flexibility

Allows barrier protection to be applied only where needed, enabling barrier and non-barrier packaging to be produced from the same blow molding line.

Sustainability

Fully recyclable, unlike multilayer packaging solutions.
