Actega and DSG team up for sustainable packaging solution

GERMAN company ACTEGA DS and US company Dayton Systems Group (DSG) present drinking products that are tailored to meet the requirements of increasingly mobile lifestyles. Thanks to the advanced resealable, non-breakable, recyclable DSG Beverage Cap Can? which provides quick-twist-off recloseability that was previously only available on glass.

Resealable Can Closures for beverages provide added value and convenience for consumers and greater shelf appeal as well as performance for the customer. This patented two-piece can and dome design is engineered to attach to standard can sizes utilising existing seaming technology and it can be made from new or recycled aluminium material.

The patented DSG Cap Can production? system is comprised of three pieces of equipment: a dome production system, a cap production system and a seal liner system to line the cap with seal material.

The seal liner system takes unlined closures and permanently attaches plastic material to the inside of the caps, thereby making it capable for pasteurisation, hot fill, cold fill, retort, and aseptic filling. To attain best efforts, especially when pasteurization is required, an extremely flexible and soft plastic is requested. With decades of experience in handling thermoplastic elastomers and developing the most demanding formulas, Actega DS had the solution on hand: SVELON 520 L, free of PVC, conforming with FDA and EU regulations, supplied as granulate to closure manufacturers. With SVELON, Actega DS offers very well accepted and established compounds for mineral water, CSD, fruit juice, tea, beer, wine/sparkling wine and milk/dairy products.

SVELON? 520 L is characterised by its excellent elastic properties, thus guaranteeing sealing to the highest technical level, especially with high concentration of carbonation and up to 60 percent alcoholic resistance. It is also suitable for cold filling, pasteurization up to 85 °C and hot-fill up to 95 °C. These compounds are based on thermoplastic elastomers. A group of materials whose enormous flexibility and high degree of thermal and media resistance has displayed major advantages in processing and recycling in practically all areas when used as an alternative to vulcanized rubber, PVC and silicone. What's more, it also largely complies with the requirements concerning efficiency of resources and energy as well as safety and health for customers and consumers.

The Dayton Systems Group Seal Liner machine extrusion takes Actega DS supplied dried blended thermoplastic SVELON 520 L, which is provided in pellet form, melts it, and inserts it into the cap. It then cold molds it into the fixed gasket utilizing the DSG patented sealing profile. The machine is equipped with an extrusion nozzle, cooling system, PC Interface operating system, defective cap reject device, and a cap output counter.
