Sustainability Without Compromising Performance: Three Approaches

One key approach is “less material.” Many films can now be produced thinner without compromising performance in use. That saves raw materials and reduces weight in transport. The important point: thinner must not mean “worse.” If a package tears or fails to seal, the result is the opposite of sustainability—products spoil, complaints rise, and food ends up being discarded.

The second approach is Design for Recycling - in other words, designing packaging in such a way that it can be more easily turned back into raw material after use. To consumers, recycling can sound straightforward: toss it in the yellow bag, done. In reality, it depends heavily on what the package is made of. Many traditional solutions are composites: multiple layers made from different polymers that together deliver strong barrier performance and good processability. Or paper structures coated with plastic. However, such compounds are not always easy to separate.

That’s why SÜDPACK is increasingly developing recyclable material structures—for example, solutions that rely more strongly on mono-material designs. In other words: using as few different plastics as possible in one package so it can be sorted and reprocessed more effectively. For customers in the food industry, this can make it easier to meet requirements and recycling targets. And in pharma and medical technology—where safety is the highest priority—work is ongoing to bring sustainability together with product and patient protection.

A third building block is alternative raw materials. Where technically and regulatory feasible, SÜDPACK offers film solutions that incorporate recycled content or use renewable raw materials. This won’t replace every application—but it broadens the options. What matters is always the specific use case: what works for a snack doesn’t automatically work for a highly sensitive medical device.
