A Greek yoghurt brand has teamed up with Australian injection moulder PakPot to launch a pack that combines two separate ingredients in individual compartments using an in-mould label (IML).
Chobani Australia’s Flip product range allows consumers to ‘flip’ the container and mix the yoghurt and dry, crunchy mix-in. The container is a twin injected polypropylene tub with a live hinge that is decorated with a Y-shaped IML label. The injection is gated through the label by means of a hole.
PakPot, a specialist in turnkey IML solutions for FMCG brand owners, said that it took 12 months between the initial idea and the finished product.
Joe Matto, chief executive of the company, explained that there are comparable IML products with two compartments and wraparound IML labels on the market, but PakPot designed a Y-shaped IML label with legally required information on the bottom and marketing and branding purposes on the sides and top.
Said Matto: “The challenge was to properly analyse the polymer flow, since double injection automatically causes a stress line where the two materials meet together (a ‘cold Weld stress joint is formed’). It was critical that this stress line would not end up along the live hinge of the packaging.”
Verstraete IML designed the Y-shaped IML and the company explained that the central drill hole allows the injection moulder to inject the centre section without obstructing a substrate, so that end result is minimum waste production.
For Chobani, the ability to produce and decorate the packaging in a single step eliminates the need to store blank packaging and therefore remove storage and transport costs.
