for all of your information...
Number 7 at the recycle symbol is not necessary has BPA
Class 7 is labeled "OTHER".. other uncommon plastic material

You're right #7 doesn't necessarily mean it contains BPA but BPA (a type of polycarbonate plastic) is under this category. So if it's #7, there's a chance that it has BPA. Since you don't know what's in it, it's safer to avoid. |
