CODE TO PLASTIK

One time I notice a plastic mineral water to drink there is a code, the gallon mineral water there are also code. codes have meaning for us know, especially about health care.

Experts in the world have agreed to create a code to identify the materials of plastics. The aim is to facilitate the consumers to recognize the danger and the security container made of plastic. The code is a number that is usually placed in the back pack in the triangle-shaped.

Code was first issued in 1988 by The Society of Plastic Industry in the United States. Furthermore, the developing countries.

How to read CODE
Triangle indicates that the plastic packaging is recycled product. Then, the code number on the triangle is related with the letter below. "The number and letter of this type of plastic penyusunnya," said Henky. Until now, there are seven code on the plastic packaging used:

• Figures 1 - PET
This means is composed of plastic polyethylene terephthalate dad. Packaged with this figure means a 30% PET. Usually this packaging material with clear or transparent. Generally used for mineral water bottles, juice bottles, glass or plastic.

Plastic packaging with the 1-PET for the one-time only. We should not use it repeatedly. This material is also not Balk to save food and hot drinks. Heat will cause the polymer layer on the bottle migrate to food or drink.

• 2-HDPE
Plastic packaging material is composed by high sensity polyethylene (HDPE). Plastic raw material is safe because it does not react to food or drink. This material is strong, hard, opaque, and more resistant to high temperature so that the regular use of bottled milk berwama white milk, tupperware, gallons of drinking water, and folding chair.

However, this package is not to be used repeatedly. For compound antimoni trioksida continued to increase over time and that it is dangerous for our health.

• 3-V.
This is the abbreviation of polyvinyl chloride (PVC), which contains in-2-ethyl-heksiladipat (DEHA), which can react with food. Gynecology DEHA easily migrate at a temperature of 15 degrees centigrade. This material is dangerous and difficult to recycle. Usually this type of plastic used for wrapping (cling wrap)

• 4-LDPE
If a sign is found in plastic, this material is made of low density polyethylene. This material made from petroleum. Is strong, somewhat translucent, flexible, and the surface is quite fatty. At temperatures below 60 degrees centigrade, is very resistant to chemical compound. Although resources have protection against fumes, water well, but less good for gases such as oxygen that.

• 5-PP
The packaging is made of Polypropylene. Found in the normal transparent bottle but not too clear or cloudy. This type of plastic berkarakter stronger, lighter, with the penetrating power of a low steam. So this type of plastic packaging for safe food and beverages. This type of plastic is also resistant to fat and stable against high temperatures.

• 6-PS
This marks the packaging is made of this polystyrene (PS) is called regular or polymer
aromatic. When meeting with the food or drink, this material can remove material styrene. This material should be avoided as dangerous to the health brain, disrupt the hormone estrogen in women result in reproductive problems, nervous system and growth. It is a good idea if we find disc.

• 7-in
This means the addition of six composed of plastic materials mentioned above. Abortion, among others, styrene acrylonitrile (SAN), acrylonitrile butadiene styrene (ABS), polycarbonate (PC) and nylon.

SAN Per usual there is a place on the food and beverages such as sports drink bottles, car spare parts, tools households, computers, electronic equipment, and plastic packaging.

Per usual for ABS lego toys and pipes. "SAN and ABS has a high resistance against chemical reactions, strong, and the level can be improved but hard safe.

The PC is usually on the bottle, glass batita children, polikarbonat drink bottles, cans and food and beverage packaging, including cans of milk formula. "Gynecology PC system potentially harmful hormones, on chromosome ovarium, the decline in sperm production, and change the function of immunity.

So, it's wise to use as a plastic container. Note the code number, do not forget to check the materials the author
