Drinking water from plastic bottles is more a habit than necessity. Did you know that by frequently drinking water from a plastic bottle you do a bad service? It is the chemical composition of the plastic. The bottom of each bottle has a triangle with a number in the middle. This number tells us how dangerous plastic is.
PET or PETE -- These marks on the bottles tells us that those bottles are for single usage because they emit heavy metals and chemicals that affect hormone balance.
PS -- emits carcinogenic substance, and is commonly used for making coffee cups and packaging fast food.
PVC or 3V -- Bottles with these two markings releases toxic chemicals that affect the body’s hormones.
PC or plastic with no markings is the worst plastic in food production that returns the secreted chemical. These bottles are often used for sports bottles and food storage vessels.
LDPE -- These plastics cannot be used for making bottles or plastic bags, but they not emit chemicals into the water.
HDP or HDPE is plastic that emits at chemicals. Water packed in bottles with these markings is clearest and most recommended.
PP -- another “good” plastic with white or transparent color, used as packaging for syrups or yogurt cups.
