German packaging group Weidenhammer Packaging Group has found the first application for a container that it calls a reinvention of the can a range of sausages sold by German retailer Muller's Hausmacher Warts.
Weidenhammer introduced the PermaSafe concept at the FachPack show in 2007, promoting the packaging as a plastic alternative to conventional glass jars and tinplate packaging.
PermaSafe is lighter than glass or metal packaging, reducing energy consumption during production and transport, but still protects food products for up to 12 months, according to the Zewnkau-based company.
The biggest challenge in the development of the new packaging was to ensure the sealing properties and to retain the label brilliance in combination with the sterilization process, said sales director Andreas Rothschink.
The injection molded, PP prototype developed for Muller's has a capacity of 5¼ ounces and features a reclosable, peelable top.
