This sign is usually listed recycling logo with the number 1 in the middle and writing PETE or PET (polyethylene terephthalate) under the triangle. Commonly used for plastic bottles, colored clear / transparent / translucent like mineral water bottles, juice bottles, and almost all other beverage bottles.
Bottle type PETE / PET is recommended only for single use. If it is too often used, much less used to store warm let alone hot water, will result in a layer of polymer on the bottle will melt and release carcinogenic substances that can cause cancer in the long term.
PETE material is too dangerous for workers associated with the processing and recycling bottles PETE bottles. PETE manufacture using antimony trioxide compound. These compounds can enter the body through the respiratory system by inhaling air containing these compounds.
Frequent inhaling these compounds can cause skin irritation and respiratory tract. For women, these compounds improve menstrual problems and miscarriage. When you give birth too, their children are likely to experience slow growth until the age of 12 months.
The majority of the world's PETE material used for synthetic fibers and raw material bottle packaging. In the textile, PETE commonly called polyester.
At the bottom of plastic bottles, recycled logo printed with the number 2 in the middle, and the writings of HDPE (high density polyethylene) under the triangle. Usually used for milk bottle white milk, Tupperware, gallons of drinking water, folding chairs and others.
HDPE plastic bottles have material properties that are stronger, harder, more opaque and resistant to high temperatures. Is one of the plastic materials that are safe to use because of its ability to prevent chemical reaction between the plastic containers made from HDPE with food / beverage packed.
Just as PETE, HDPE is also recommended for single use only because of the release of antimony trioxide compounds continue to increase over time.
3. V / PVC
Written (sometimes red) with the number 3 in the middle, and the writings V.
V it means PVC (polyvinyl chloride), which is the most difficult types of plastics recycling. This can be found on the plastic wrap (cling wrap) and bottles.
The reaction between PVC with foods that are packed with plastic is potentially harmful to the kidneys, liver and body weight. PVC containing DEHA (diethylhydroxylamine) that can react with foods that are packaged in plastic made from PVC is now in direct contact with food such as DEHA is melted at a temperature of -15 ° C.
Recycling logo with the number 4 in the middle, and the writings of LDPE. LDPE (low density polyethylene) plastic is the type of chocolate (thermoplastic made from petroleum), usually used to place food, plastic packaging, and bottles of soft.
Mechanical properties of LDPE type is strong, transparent, flexible and somewhat greasy surface, at a temperature of 60 degrees is very resistant to chemical reactions, the protection against water vapor are classified as good, can be recycled as well as good for those items that require flexibility but strong.
Goods made from LDPE are difficult to destroy, but still good for the food because it is difficult to react chemically with foods that are packed with this material.
Recycling logo printed with the number 5 in the middle, and writing bytes. Characteristics are usually transparent bottles that are not clear or cloudy. Polypropylene is stronger and lighter with low vapor permeability, good resistance to fat, stable against high temperature and quite shiny.
Type of PP (polypropylene), this is the best plastic material selection, especially for the food and drinks like a place to store food, drink bottles and most drink bottles for babies.
Look for the code number 5 when buying goods made from plastic containers to store various foods and beverages.
Recycling logo printed with the number 6 in the middle, and writing PS. Usually used as an ingredient where to eat styrofoam, disposable drinking places, and others. Polystyrene is an aromatic polymer that can release styrene material into the food when the food is touching.
Besides the food, styrene can also be obtained from cigarette smoke, fumes and building construction materials. This material should be avoided, because in addition harmful to brain health, disrupt the hormone estrogen in women that result in reproductive problems, and growth and nervous system, also because this material is difficult to be recycled. When recycled, this material requires a very long process and long.
This material can be identified by code number 6. However, if no digit code printed on the packaging of plastic, this material can be recognized by burning (a last resort and should be avoided). When burned, these materials will be issued a yellow-orange flames and leaving soot.
Recycling logo printed with the number 7 in the middle, and OTHER posts. To 7 Other types of plastic have 4 types, namely:
1. SAN - styrene acrylonitrile,
2. ABS - acrylonitrile butadiene styrene,
3. PC - polycarbonate,
Can dtemukan on where food and beverages such as sports drink bottles, auto parts, appliances, computers, electronic equipment and plastic packaging.
SAN n ABS has a high resistance against chemical reaction n temperature, strength, stiffness and level of violence which has been enhanced.
SAN usually found on the mixer bowl, wrapping flasks, dishes, cutlery, coffee filters and a toothbrush.
While ABS is commonly used as pipe material and lego toys. This material is one of the plastic material which is excellent for use in packaging food or beverages.
PC (polycarbonate) dpt found in plastic baby bottles, toddler cups (sippy cup), polycarbonate drinking bottles and food packaging and beverage cans, including cans of infant formula.
This material may issue a main ingredient that is Bisphenol-A into the food n drink that has the potential to damage the hormone system, the chromosomes in the ovaries, decreased sperm production, and alter immune function.
Use recommended not used to place food or beverages. Ironically bottle of milk is likely to undergo a process of heating. Whether it's for the purpose of sterilization by boiling, microwave or heated by pouring hot water.
The conclusion of the plastic classification mark:
* Be careful in using plastics, particularly the codes 1, 3, 6 and 7 (PC), all have a chemical hazard. Use only disposable!
* Self-safe when using plastic with codes 2, 4, 5 and 7 (SAN or ABS)
For parents who still need a bottle of milk for your son or daughter:
* Select and use baby bottles made from glass, or plastic type 4 or 5.
* Use baby cups made from stainless steel, or plastic type 4 or 5.
* For a dot, use the silicone, as it will not issue a carcinogenic substance as the dot made from latex.
* Prevent the use of baby bottles and baby cups (with holes penghisapnya) made from type 7 PC (polycarbonate),
* If the use made of polycarbonate plastic can not be prevented, do not store food or drinking water in hot conditions.
Avoid using plastic bottles for storing drinking water. Commonly used to place water in the refrigerator.
If the use made of PET plastic bottles (coded 1) and HDPE (Code 2) can not be prevented, use only disposable and quickly spent. Replace with stainless steel or glass bottle / glass.
