In my opinion, even more plastic waste is completely unnecessary. Why should meat/cheese packaging, etc. "a kind of Tupperware packaging with a plastic lid that closes well"? The product will then only become more expensive... Makes no sense to me. The current packaging fulfills its purpose and is totally fine; if you want to pack meat/cheese etc. airtight after the first opening, then buy a Tupperware container (https://produkte.migros.ch/sortiment?q=topline) and store the meat/cheese in it in the fridge. The same applies to fruit, vegetables, etc. Migros has many suitable containers with Topline. Otherwise, there's also the competition if you can't find a suitable Tupperware container at Migros.
