Plastic bottles labeled with letters like HDP, HDPE, PP and a few others, do not release any toxic material in the water, and the remaining letters can represent the chemicals found in the water you are drinking.
Every brand must label the content of the bottle, they will either have the letters, numbers or number symbols shown in the graphic.
#1 PET OR PETE
– stands for single-use bottles. These bottles can possibly release heavy metals and chemicals that affect the hormonal balance.
“PET is one of the most commonly used plastics in consumer products, and is found in most water and pop bottles, and some packaging. It is intended for single use applications; repeated use increases the risk of leaching and bacterial growth. PET plastic is difficult to decontaminate, and proper cleaning requires harmful chemicals. Polyethylene terephthalates may leach carcinogens.”
#2 HDP OR HDPE
– plastic that practically releases no chemicals. Experts recommend choosing these bottles, when buying bottled water, because it is probably the healthiest water you can find on the market.
“HDPE plastic is the stiff plastic used to make milk jugs, detergent and oil bottles, toys, and some plastic bags. HDPE is the most commonly recycled plastic and is considered one of the safest forms of plastic. It is a relatively simple and cost-effective process to recycle HDPE plastic for secondary use.”
#3 PVC OR 3V
– releases 2 toxic chemicals that affect the hormones in your body.
“PVC is a soft, flexible plastic used to make clear plastic food wrapping, cooking oil bottles, teething rings, children’s and pets’ toys, and blister packaging for myriad consumer products. It is commonly used as the sheathing material for computer cables, and to make plastic pipes and parts for plumbing. Because PVC is relatively impervious to sunlight and weather, it is used to make window frames, garden hoses, arbors, raised beds and trellises.”
– this plastic cannot be used in the production of bottles, but plastic bags, even though it does not release any chemicals into the water.
“LDPE is often found in shrink wraps, dry cleaner garment bags, squeezable bottles, and the type of plastic bags used to package bread. The plastic grocery bags used in most stores today are made using LDPE plastic. Some clothing and furniture also uses this type of plastic.”
– another white colored or semi transparent plastic, used as a packing for syrups and yoghurt cups.
