Question

When you look under your plastic water bottle, there is a recycling sign with a number in it. What does it mean?

Answer 1

Answer:

Number 7 plastics are used to make baby bottles, sippy cups, water cooler bottles and car parts. A 1 inside the triangle indicates the plastic is polyethylene terephthalate, which is shortened to PET or PETE

Explanation:

To summarize, plastics in categories #2, #4 and #5 are generally considered safe.  Plastics #1, #3, #6 and #7 should be used with varying to extreme caution, especially around food or drink.

And, as there are seven categories of plastics, a number from one to seven is set inside the triangle to tell you which kind of plastic you've got.
