Amcor Flexibles has launched its patented Amcor Opening Feature (AOF) for child-resistant blister lidding packaging. The first products using AOF on blister lidding were commercially launched in December 2014.
With AOF, blister contents are accessed with a targeted push-through motion rather than the traditional peel or peel-push method often required for child resistance.
AOF allows the use of a 2-ply structure compared to a standard 3-ply, which is only the start of the sustainability benefit of AOF Blister Lidding. Because peel tabs are not required, total package sizes can be reduced up to 40% versus traditional peel-push and peelable blister cards. Even with this 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% compared to the normal target minimum of 90%.
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.
