The packaging paper product from Koehler Paper provides ideal protection for “einpott” ready-to-eat meals thanks to its extraordinary oxygen, mineral oil, and grease barrier properties. pack&satt products are available in three flavors: “Tomate Linse” (lentils and tomato), “Curry Linse” (lentil curry), and “Rote Bete Kartoffel” (red beet and potato). pack&satt ready-to-eat meals were originally bottled in returnable jars. However, customer feedback, coupled with a general overhaul of the product, led the company to look for alternative packaging options: “Our customers frequently told us that if they had an electric kettle, that meant that they also had bowls or cups available, making the jars redundant. And on top of that, we found out that using paper instead of glass to hold dry product would improve our environmental footprint! Given all that, we were tremendously happy when we found Koehler and saw that they offered the right packaging material for our needs,” explains pack&satt founder Sophie Gnest.
