Not sure that 'Nearly exclusively made from plastic' is accurate or appropriate without citation. Even ignoring big brands like klean kanteen, aluminium and steel canteens are very common because of superior drop resistance (they bend instead of break) and their ability to be effectively cleaned after becoming mildewy. 2.223.104.131 (talk) 03:00, 26 November 2018 (UTC)[reply]

Nonsense: modern polymers are as durable and more insulating than aluminum or steel. When these polymers are properly reinforced, e.g. with fiberglass or nylon, they make an infinitely more suitable container which is simpler to design and produce. While not common knowledge, this is plainly irrelevant to do with canteens and entirely everything to do with materials science. Rubbers increase the durability by bouncing instead of breaking, but are susceptible to "drying out" from sun damage or natural oil seepage. We should focus on the construction and its means. Everyday containers except tin cans are being replaced with cheaper and (sometimes) more durable polymers. Tin cans (in at least the US and EU) are being phased out as much as possible for PVC and LDPE in paper packaging: the quality may be lacking, but the logistics pricing, durability, and shelf life are undeniably favorable. The space-age polymers of yesterday are the panacea to modern-day food (and therefore water) packaging & handling. Anyone reading this knowledgeable in plastics: your citations would make this article 100% more informative. 2600:1011:B11D:AA9:9ED1:E54C:509A:BE79 (talk) 11:58, 6 March 2022 (UTC)[reply]
