I really have no idea how to find it. I went to buy just the plywood & mdf sheets and accidentally stumbled upon it. It was a furniture warehouse, not exactly a shop. I can't visit that place again as I've shifted to another city. If i have to take a wild guess i think foam sheets like this are used to protect laminates. I'll try to ask a few people i know in woodworking if they know where this kind of foam is used. They might have an idea. I'll post here if i find anything. Yep. It is. I have some packing foams as well but they're a bit stiffer.
