Is #7 plastic safe in water bottles?

Question

Is #7 plastic safe in water bottles?

Answer 1

i heard they were bad cause they might cause cancer.

Answer 2

#7 plastic is listed as "others" in the recycling plastics categories. They are combination of various types of plastics or other plastics not listed in 1-6. By itself #7 plastics does not allow one to determine its safety nor performance. Assuming you are the end user, you need to check the product description on the water bottles. If you are water bottle manufacturers, you need to have a better knowledge of the raw materials before you use it to make your water bottles.

Answer 3

Yes, it's safe so long as you don't heat the plastic.  It starts to decay at around 175 F.  If you heated the water in say, a microwave, it's possible to get hot spots that are sufficiently hot to allow the chemical to get into the water.  Also, aged plastic does release chemicals - that's why water stored for say 4 or 5 years tastes funny.

Answer 4

#7 "Other" is suspected of leaching harmful carcinogous chemicals into the contents of the bottle because it's an "unknown" combination.  Chances are the trace chemicals are so minute it probably won't hurt you in all reality, but why take a chance since there are other options available?

Answer 5

They are no longer on the safe list. I put a link for information and sources for safe bottles.

Answer 6

#7 is everything from a combination of recycled #1-6, but also alternative plastics, such as corn and potato.
