Stora Enso AT Master enables tightness verification of airtight packages

Stora Enso is introducing a new food packaging solution at Interpack: an airtight cup made from non-foil paperboard. Tightness, which is achieved through a combination of specially developed paperboard, heat-sealed raw-edge taping and innovative lid sealing, can be tested and verified with the unique 'Stora Enso AT Master' tightness-testing equipment, based on tracer gas.

The new cup lends itself to far more than drinks and has high potential in areas where innovative design and user-friendliness are key objectives. Airtight cups developed by Stora Enso take food packaging opportunities to a completely new level. Made from a special paperboard with high barrier coating, the airtight cups are ideal for snacks, cereals, confectionery, biscuits, tea and regular and instant coffee, for example. The airtight cups must pass a wide range of quality inspections, including a 'Stora Enso AT Master' tightness test. The equipment uses hydrogen as a tracer gas, which is easy and safe, cost-effective and 100% reliable.
