It’s something I’ve thought about as well, and I’d like to see a change.
If the issue is shelf life, then why not offer a resealable, branded, re-usable container, which could be washed and reused many times, to store the product. That would allow for the option of an alternative recycled/recyclable packaging for shipment? There’s a lot of work going into natural and totally biodegradable packaging solutions in various countries right now, such as India, which has just banned the use of single use plastics.
I’d have absolutely no problem paying extra for this or signing a disclaimer each time I purchase, that making this choice could mean my product could be damaged and leak in transit. It already comes in a big cardboard box, so damage in transit is less likely. I’d also like to see the plastic air pouches for shipping stop being used, and something made from a recycled/recyclable material used instead.
No matter how small the amount of plastic currently used is, we should always be looking at ways to stop using it altogether, and switch to biodegradable products. I agree though, that it has to be considered and will take time.
