GASTOP-FlexTM boosts flexible packaging barrier performance in compliance with circular economy design guidelines

Ampacet GASTOP-FlexTM technology allows to address the trends towards a reduction of plastic packaging wastes and higher circularity.

Gas barrier properties of polyolefin flexible packaging are typically increased with the use of thicker packaging, co-extruded barrier material or multi-material laminates. Thicker packaging, however, is not optimum in terms of packaging material resource efficiency, especially at times when brand owners pledge to reduce the amount of plastic used in their packaging. Multi-material coextruded or laminated packaging are often not fully compatible with packaging waste recyclability requirements.

Added to polyolefins, GASTOP-FlexTM masterbatches boost the inherent packaging barrier performances with a reduction of both oxygen and water vapor transmission rates by up to 60% of their initial values.

GASTOP-FlexTM technology enable down-gauging of general-purpose packaging used for dry food (e.g. bag-in-box cereal liners) preserving the barrier to moisture (WVTR) and shelf-life of packed dry food. GASTOP-FlexTM also allow to achieve high barrier packaging performances (OTR and WVTR) while keeping the EVOH content below the maximum 5% threshold specified by the most popular design guidelines for circular economy.

Adding GASTOP-FlexTM to packaging will support packaging manufacturers and brand-owners to achieve their sustainability goals in reducing the quantity of plastic packaging material and wastes and designing packaging with a higher compatibility with existing sorting and recycling infrastructures.
