Supermarkets, stop selling non recyclable packaging!

I would like to ask you do something about the horrendous waste of resources regarding supermarkets and food packaging companies. Supermarkets own brand products are generally cheaper, but my observation is that this comes at the expense of using non recyclable packaging. All large companies even Aldi which gives a large well informed pledge to their commitment to the environment and yet at the same time most of their products packaging is non-recyclable? other large chains sell their own brand products too, again a lot of these seem to come also in non recyclable packages. In this day and age when we are being encouraged, and some do their utmost, to recycle as much as we can our bins are stuffed with this stuff which ends up in landfill- What is going on? why if some companies can do it then why not all. All our food should come this way - Also less of it too, as its totally unnecessary!
