What Swiftpak learnt at Fachpack?
Despite there being less exhibitors, there was so much to learn at Fachpack this year. From all the presentations, it was clear that paper-based packaging is only going to continue to grow in popularity.
We also learnt that when it comes to construction of objects including packaging organic and interconnected structures are the future. When the structure is ‘straight’ it is considered to be less stable and not as strong compared to those that were more curved and interconnected. The speakers pointed out that with an airplane model, they used to be designed with straight lines as well until it was realised that the model was stronger if they were curved and had a more interconnected/woven pattern.
There also seems to be continued confusion over sustainability as well as in the term “biodegradable” and what properties a product should have to fall under these categories. Here are some pointers from presentations:
- Biodegradable does not mean it can’t be from petrol/biofuel.
- Biobased polymers are not the same as biopolymer. Biopolymers are very expensive!
- Different compostable methods include home (1-year lower temperature) and industrial (3 months).
- Recycled grade is currently better than compostable (industrial) as products are not often picked up for composting.
- Chemical recycling takes a lot of energy – from polymer to monomer.
