RPC Containers Llantrisant has created a 330ml bottle for UK milkshake brand Shaken Udder, generating ‘significant’ sales growth for the company.

The PET bottles, shaped like a traditional milk churn, have a 38mm three-start UCS neck and are easily recyclable.

Shaken Udder co-founder Jodie Farran said that the bottles were unique and allowed the brand’s logo to sit comfortably and make the maximum impact on the shelf.

RPC Llantrisant produces a range of injection stretch-moulded and extrusion blow-moulded bottles and containers, ranging in size from 50ml to 2l, for the lifestyle drinks, personal care, pharmaceutical, car care, veterinary and household chemical markets.
