Little Bug, founded in 2006, is a baby food producer in California. They are only using local, seasonal and organic ingredients. In the packaging development they were looking into safety, environmental impact and freezer functionality. They first tried out a biodegradable material, but realized quite soon that it will crack and shatter in the freezer. They checked paper, but it would leak meanwhile glass would be too heavy in transportation. So after all the decision was PP, a number 5 recyclable plastic. The outer box is made of paper.
