Aware of the Plastic Bottles

Did you ever aware of the triangle symbols on the bottom of plastic bottles with a number inside?



The triangle symbols with a number is stand for:
1) Polyethylene terephalate (PET)
2) High density polyethylene (HDPE)
3) Unplasticised polyvinyl chloride (UPVC) or Plasticised polyvinyl chloride (PPVC)
4) Low density polyethylene LDPE
5) Polypropylene (PP)
6) Polystyrene (PS) or Expandable polystyrene (EPS)
7) Other, including nylon and acrylic

Most of the plastics used are toxic and the chemicals that used to create a plastic can leach out of the plastic and into the food or drink.

For your information, the worst ones are 3, 6 and 7. Try to avoid from using any product with these number.
