THIN WALL MOULDING | INNOVATION
Cost benefits of thin wall moulding stack up
The current climate of high material and energy costs indicate the importance of development in thin wall moulding. Chris Saunders looks at technology and application advances along the value chain
Thin wall moulding has been growing on the basis of its benefits in material and energy usage and costs. Yet despite market growth in recent years, the snowballing costs of power and raw materials combined with the shift toward a circular economy and increasingly strict regulations mean that the pressure is now on for thin wall moulders to be more efficient and cost effective than ever before. The practical benefits of thin-walled packaging
are generally measured in weight and space reduction, which cuts material use, transportation costs, and CO2 emissions. Berry Global recently achieved a significant weight reduction for the 1kg UniPack container it supplies to Milchwerke Schwaben. Jakob Ramm, the German dairy producer’s MD, says: “We wanted a weight reduc- tion, and we achieved almost 19% which we are very satisfied with. The 1kg [of product] container now weighs 35g as opposed to 43g. Also, thanks to alterations in the design, we can now load more

containers onto each pallet. In addition, after modifying our filling line slightly to fit the rede- signed container, we have fewer handling costs and our filling line simply runs much better now.” Due to the redesigned container’s reduced
headspace and improved indexation, Milchwerke Schwaben can now fit a total of 594kg of contain- ers on each pallet as opposed to 540kg, and all the advantages have been achieved without impacting the container’s effectiveness. Diversification of design also enabled Berry to
produce the signature mortar-shaped pot for Spanish food producer Choví Group’s garlic mayon- naise brand, Allioli, which helps meet sustainability objectives by incorporating 25% rPP. The recycled content has been allocated using the ISCC Plus- certified mass balance approach, and the entire pot can be recycled where appropriate facilities exist. The change in the pot’s material composition came about through an alliance between Choví,
