The 3 ply Capsteril® alufoil laminate closure from Vaassen Flexible Packaging, in combination with the Sensocap® screw cap from Ampack. This closure provides innovative contribution to Consumer Convenience in improving shelf life of aseptic products, without requiring a separate peeling process for the foil membrane. This is an ingenious design which removes the necessity to ‘double open’ an aseptic pack and also provides a clean neck for the consumer to drink straight from the container without fuss. It offers many advantages for the consumer, including the retention of the membrane as a cushion in the screw cap to aid resealing. The presence of alufoil in the laminate structure specifically enables pre-heating of the capping foil so that the alufoil layer aids the heat generation required to kill any bacteria present. However, indications are that consumers would rather have only one closure and do not like a sealing membrane having to be removed as an additional step. The combination of the Sensocap®’s special blades and the peelability of the Capsteril® capping foil ensures easy and clean peeling of the capping foil from the bottle during the initial opening of the screw cap. The capping foil remains inside the cap, serving as a sealing gasket after reclosing. This solution offers the consumer the shelf life of an UHT/aseptic product (up to 9 months, depending on product) with the consumer experience of a screw cap normally used for fresh products, with an extended shelf life (60 days). The alufoil laminate membrane comprises top lacquer/alu20/PET100/alu20/heat seal layer, the latter being either a sealing lacquer or a laminated seal film
