Romaco and Huhtamaki jointly showcase recyclable strip packaging for pharmaceutical solids

An HM 1-230 heat-sealing machine from Romaco Siebler will be used to manufacture the Push Packs.

Pharmaceutical manufacturer Romaco Siebler and foil specialist Huhtamaki will be launching the recyclable unit dose packaging for solid pharmaceutical products. The newest Push Pack model is made from recyclable polyolefin laminate. The structure of the strip packaging foil enables it to be recycled back into the material loop. More than 90% of the components which are used to make the packaging belong to the same material class (PE and PP). The result is a primary packaging recycling rate of better than 70%. Huhtamaki’s foil is processed into four-side sealed strips with a push-through function using Romaco Siebler’s heat-sealing technology. Romaco and Huhtamaki developed the recyclable Push Packs as a joint step towards more sustainable pharmaceutical packaging.

Push Packs save material and costs
As far as the eco-balance is concerned, the packaging forms in the Push Pack product family have inherent advantages over conventional blister packs. This is due to the lower material consumption, especially in direct comparison with Al/Al blisters. The Push Pack foil exhibits the same barrier properties as blister foil but is much thinner and lighter.

The heat-sealing machines in Romaco Siebler’s HM 1 series process this ultra-thin primary packaging foil into air, light and moisture-tight push-through strips. The QuickSeal technology was developed by Siebler specifically for handling laminates with an aluminium foil thickness of between 9µm and 25µm. Push Packs are consequently less than half the weight of Al/Al blisters. The material saving is additionally reflected in the costs: Push Packs are up to 60% cheaper than Al/Al blisters.

Regardless of whether the standard, barrier or eco version of the Push Packs is chosen, all packaging forms are made from PVC-free material. Since the relatively small cavities in the Push Packs also mean smaller air pockets, the medicines have a longer shelf life. Romaco can supply the push-through sealed strips in various geometries and designs on request. All Push Packs have a large surface that can be printed on both sides. Siebler heat-sealing machines pack between 800 and 7000 tablets per minute depending on requirements.

Romaco at CPhI 2019
Romaco will be represented at this year’s CPhI Worldwide, which will be taking place from 5-7 November 2019 in Frankfurt, at three separate booths. At the booth of the specialist engineering firm’s parent company Truking (110C30), Romaco will show all-in-one solutions for pharmaceutical applications. Romaco Innojet will exhibit the VENTILUS V 2.5 processing machine at the stand of its industry partner Biogrund (102C22). Visitors will also have a chance to experience Push Packs live in the making on a Romaco Siebler HM 1 heat-sealing machine at the Huhtamaki booth (111B53).
