Hi guys how is it going, I have a plastic cookware idea that I'd like to try out on Kickstarter, but have had a pretty difficult time figuring out which plastics are microwave safe. Below is the best info I was able to find. But based on that info, it seems like I can't use any plastics without the worry of health concerns. I was wondering if any of you have designed plastic cookware before and are familiar with the plastics, processes, and approvals required to bring something to market. I plan to go to Target/Walmart later today to buy some microwave safe plastics and see what they are made of, but I'm concerned that they may have some sort of proprietary additive/process that allows them to be considered microwave safe. Thanks! Info from http://www.scn.org/~bk269/plastics.html Type 1 - polyethylene terephthalate (PET) May be safe if marked "microwave safe", although some recommend against food contact when microwaving. Type 2 - high density polyethylene (HPDE) May be safe, although some recommend against food contact when microwaving. Type 3 - PVC, polyvinyl chloride, vinyl Do not use in microwave. Also, PVC often contains bisphenol A (BPA) Type 4 - low density polyethylene (LDPE)(mixed commentary regarding microwave safety) Type 5 - polypropylene - May be safe, although some recommend against food contact when microwaving. "Type 5" are the most commonly labeled "microwave safe". Despite this, I have observed "Type 5" containers with partially dissolved surfaces, apparently from microwave use. Type 6 - polystyrene, styrene, polystyrene foam Not heat stable. Do not use in microwave. Type 7 - polycarbonate; "other" (can contain bisphenol A (BPA); most polycarbonate contains bisphenol A) Do not use in microwave.
