By combining the barrier properties of strip packaging with the opening mechanism of blisters, you get push packs. The push packs use less packaging material than PVC and Al/Al (aluminium-aluminium) blisters, but still leaves extra space for printing brand and marketing messages. Push Packs are available in standard rectangular formats or as customized strip designs, using the unique die-cutting technology from Romaco Siebler.
Innovative packaging with numerous design possibilities
Together with film and foil specialist Huhtamaki, Romaco Siebler is presenting an innovative new packaging form for pharmaceutical solids. The Romaco Siebler Push Pack is a push-through sealed strip packaging that can be opened like a blister by pressing the tablet out of the pack.
The unique die-cutting technology from Romaco Siebler provides the possibility of individually shaped Push Packs. The surface is printable on both sides and since the cavities are smaller than traditional Al/Al blisters, Push Packs have a larger printable surface. This leaves extra space for branding and marketing messages thus providing pharmaceutical manufacturers more options for marketing their products.
Excellent barrier properties
The four-sided sealed foil packs are ideal for air, light and moisture sensitive products due to its excellent barrier properties, which also offers extended shelf life. At present, users can choose between 9 µm and 25 µm as the aluminium foil thickness and the push-through foil can be combined with either a multilayer laminated or a transparent barrier foil. Furthermore, the packaging material does not tear and is therefore regarded as child resistant. Push Packs are also senior friendly because the tablets are easy to remove from the foil.
Cost efficient option compared to Al/Al blisters
Push Packs are a good alternative to cold formed Al/Al blisters, but in regard to sustainability and environmental compatibility, the lower consumption of packaging material is a real benefit of Push Packs that cannot be matched by Al/Al blisters. Although both of these primary packaging forms demonstrate excellent barrier properties, far less foil material is required to manufacture Push Packs than to make Al/Al blisters. Push Pack packaging foil is much thinner and weighs less than Al/Al blister foil, which leads to a significant reduction in material consumption and cost savings of up to 60%.
