Amcor Flexibles introduces its patented Amcor Opening Feature (AOF) for child-resistant blister lidding.This technology has been readily available on pouch stock and stick packs for the pharmaceutical market, and the first products using AOF on blister lidding were commercially launched in December 2014.

With AOF, blister contents are easily accessed with a targeted push-through motion rather than the traditional peel or peel-push method often required for child resistance. The result is improvements in senior friendliness, child resistance, and sustainability, according to the vendor.

AOF allows the use of a two-ply structure compared to a standard three-ply structure.Because peel tabs are not required, total package sizes can be reduced up to 40%.Despite a reduction in material usage and weight, AOF maintains product stability with no compromise to the barrier layer or the seal integrity of the package.

The senior-friendly qualities and child resistance of AOF blister lidding were confirmed through an independent study in accordance with the requirements of 16 CFR Part 1700.Blisters were produced using AOF blister lidding, and the package met the test requirements of F=1 (only two children out of 50 were able to access one cavity).In addition, the Senior Use Effectiveness (SAUE) score was 98%.

The product contact layer remains the same as existing Amcor blister lidding products, which allows current customers to adopt the new technology with streamlined testing protocol.
