THE CHEMICAL MATERIAL OF THE PLASTIC


Did you ever drink from a plastic bottle and see a triangle symbol on the bottom with a number inside?

Do you know what the number stands for ??
Did you guess that it's just for recycling ?
Then you are WRONG!!!!!

THE 'NUMBER' TELLS YOU THE CHEMICAL MATERIAL OF THE PLASTIC ....

No. 1 Polyethylene terephalate (PET)
- Normally 'Mineral water bottle' widely using this.
- Temparature can last up to 70 centigrade, cannot longer use...
- In 2003, Italy researched & discovered that after using about 9 months
later, will release (DEHP) which may cause level of cancer.
- When higher (DEHP) in male body, it will reduce the spermatozoon & damage spermatozoon.


2 *** High Density polyethylene (HDPE)
- 'Milk bottle', Thick Platic bag
- Temparature can last up to 120 centigrade. ** Is a stable material.**


3 Unplasticised polyvinyl chloride (UPVC) or Plasticised polyvinyl chloride (PPVC)
- Normally PVC pipe, rain coat, Platic cup, others.


4 Low density polyethylene (LDPE)
- Normally Thin Plastic bag
- Temparature can last up to 80 centigrade.


5 *** Polypropylene (PP)
- Norrmally Micro Wave container , Water bottle.
- Temparature can last up to 135 centigrade. ** Is a stable material.**


6 Polystyrene (PS) or Expandable polystyrene (EPS)
- Type of light plastic material - Polyfoam
- Temparature can last up to 90 centigrade.


7 (PC) is widely use material or (Other) material including nylon and acrylic, other unknown materials
- Is a common Water bottle material, normally free gift of water bottle from company.
- Will release (bisphenol A). Stop by Japan.
- Temparature can last up to 135 centigrade.


What you aren't told is that many of the plastics used are toxic and the chemicals used to create a plastic can leach out of the plastic and into the ' food / drink '. Think about it, how many times have you or a friend said 'I don't like this, it taste like the plastic bottle .... ' THAT'S BECAUSE YOU ARE TASTING THE PLASTIC '

Besides No. 1, should reject to use No. : 3, 6, and 7.

The WORST ONES are No. : 3, 6, and 7.

Check out this chart that breaks down the plastic, its uses and chemical makeup
(I find No.7 a little scary)

Reusing plastic bottles by refilling them is NOT a good idea. WATCH THE VIDEO:

Microwaving plastic containers affects the chemical make up of the plastic, allowing the chemical substances to destabilize and leach out more quickly into the food you are reheating. You can check out this article that ran in the Wall Street Journal:

EVEN one of my favorite 'RUMOR DEBUNKING' websites, lists the information as: overblown with a grain of TRUTH
