Here are the following facts to be noted while using plastic.
1 . When you’re purchasing lunch boxes which are to be re-used.You need to be careful about PVC.
2. Many lunch boxes have a PVC lining to help with insulation. Avoid products that say “vinyl” or have the letter “V” with a #3 recycling symbol on them. If you can’t find a label, check with the manufacturer.
3. Look for the keywords “PVC-free,” "BPA-free," “vinyl-free,” and “lead-free,” or purchase stainless steel, fabric, or neoprene (the wetsuit material) lunch sacks. Safe plastics include #1 PET, #2 HDPE, #4 LDPE, and #5 PP. (In other words, avoid #3 PVC or V, #6 PS, and #7 PC)
4. If you prefer plastic, make sure your item is made of one of these types of plastics: #1 PET, #2 HDPE, #4 LDPE, #5 PP, or nylon, and look for the keywords “BPA-free,” “phthalate-free,” “lead-free,” and “PVC-free.” Hemp and organic cotton wraps are also great alternatives.
5. When you’re purchasing a reusable water bottle.
Watch out for BPA. This known hormone-disrupter has made its way into all kinds of products and is often found in plastic drink bottles and in the liners of aluminum bottles.
6. Purchase an unlined/uncoated stainless steel water bottle -- they won’t leach. If you want a lighter alternative, try an aluminum bottle, but if it has a lining/coating make sure it's BPA-free. If you prefer plastic, avoid #7 PC (polycarbonate) and choose a BPA-free reusable bottle made of one the following instead: #1 PET, #2 HDPE, #4 LDPE, and #5 PP.
