An open can is not portable. A resealable one is. Actega and Dayton Systems Group have created a pretty significant milestone in the history of the drink can.
The patented two-piece can and dome design is engineered to attach to standard can sizes using existing seaming technology and it can be made from new or recycled aluminium material.
DSG Cap Can production system uses 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, making them usable for pasteurisation, hot fill, cold fill, retort, and aseptic filling. Actega's extremely flexible and soft plastic allows them to meet the most stringent needs of pasteurisation. Actega's Svelon520 L is free of PVC, conforms with FDA and EU regulations, and is supplied as granulate to closure manufacturers for mineral water, CSDs, fruit juice, tea, beer, wine/sparkling wine and milk and dairy products. Its excellent elastic properties give Svelon ultimate sealing - even for the highest concentration of carbonation - and up to 60% alcohol resistance. It is also suitable for cold filling, pasteurisation up to 85 °C and hot-fill up to 95 °C. Svelon compounds are based on thermoplastic elastomers, a group of materials with high level flexibility and a high degree of thermal and media resistance, making it superior to vulcanised rubber, PVC and silicone. It also scores highly in resources and energy efficiency and consumer safety.
To create the can cap, the Dayton Systems Group seal liner machine extrusion melts Svelon 520 pellets and inserts them into the cap, then cold moulds them into the fixed gasket using DSG's 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.
Actega DS will present its new cap at interpack in Düsseldorf, May 8 - 14, 2014, Hall 11, Stand A 12, and at Metpack, May 6 – 10 in Essen, Hall 3, stand M 30.
