Oh yes, in fact since 1998 it issued the code of The Society of Plastic Industry in the United States and is the reference by institution - institution of system development such as code ISO (International Organization for Standarization). In general, code should be issued or located at the bottom, a triangle, in the triangle are the numbers and kinds of plastic there is a name under the triangle. The kind of code or symbols are 7 types of plastic identification.
1. PETE or PET
Usually these signs indicated the recycling logo number 1 in the middle and hold any posts PETE or PET (Polyethylene Terephthalate) under the triangle.
Used for plastic bottles, colored clear / transparent / translucent bottles of mineral water for example, bottled juices and almost any other beverage bottles.
It should be stressed to the type of PET or PETE bottles used ONLY ONCE ONLY, because if too often used especially often used to keep warm or hot water can result in a polymer coating on the bottle will melt and remove a carcinogenic substance which in the long term can cause cancer.
For workers associated with the processing of PET or PET plastic recycling should be vigilant because in making PET there is a material called antimony trioxide, antimony trioxide material that can enter the body through the respiratory system, which is due to inhaling dust containing these compounds. In the long term will result in skin irritation and respiratory tract. And for women workers of these compounds can improve menstrual problems and miscarriage, when giving birth, their child will most likely experience a slow growth until the age of 12 months. In the majority of PET plastic material for synthetic fibers (about 60%), commonly used in PET textiles with polyester, bottom of the bottle packaging materials 30%.
2. HDPE
Usually these signs indicated the recycling logo number 2 in the middle and hold any posts HDPE (High Density polythylene) under the triangle.
Usually used for milk bottle white milk, tupperware, gallons of drinking water, folding chairs and others - others.
HDPE has a stronger material properties, hard, opaque and more resistant to high temperatures.
Although HDPE plastic material including one that is safe to use because of its ability to prevent chemical reaction between the plastic packaging made from HDPE with food / drink packed but is recommended only for USE ONCE only because of the release of antimony trioxide compounds continue to increase over time.
3. PVC or V
Usually written in red with the number 3 in the center accompanied by writings V. V meaning to refer to the PVC (Polyvinyl Chloride) is the most difficult type of plastic for recycling.
Often found in plastic wrap (Cling Wrap), and a bottle - bottle.
If PVC is used for food is potentially harmful to the kidneys, liver and body weight.
4. LDPE
Usually painted recycling logo with the number 4 in the center and the writings of LDPE. LDPE Low Density Polyethylene itself means that the type of brown plastic (Thermoplastic / made from petroleum), which is normally used for food, plastic packaging and bottles - bottles of soft.
Mechanical properties is very strong, transparent, flexible and slightly greasy surface, at a temperature of 60 degrees is very resistant to chemical reactions, the protection against water vapor classified as good, can be recycled as well as for goods - goods that require flexibility but strong.
Goods are made from LDPE is very difficult to destroy, but good for the food because it is difficult to react chemically with foods that are packed with this material.
5. PP
Usually the emergency re-painted logo with the number 5 in the middle, as well as the writings of PP. PP stands for polypropylene, the characteristic is transparent bottles that are not clear or cloudy.
This material is stronger and lighter with low vapor permeability, fat resistant, stable to high temperatures and quite shiny.
This material is the BEST PLASTIC MATERIALS, both for extra food and drinks.
6. PS
Usually painted recycling logo with the number 6 in the center, as well as writing the PS.
Usually used to place Styrofoam food, disposable drinking places, and others - others.
PS is polystyrene which is an aromatic polymer that can release styrene material into the food when the meal was touching. Besides the food, styrene can also be obtained from cigarette smoke, fumes and building construction materials.
This material should be avoided, as dangerous to the health of the brain, can disrupt the hormone estrogen in women that result in reproductive problems and nervous system growth.
Materials of this type is difficult to be recycled, although it can in the recycling process requires a very long and long.
Another way to identify the content of PS in a container that is not listed on the score that is most stuck to be burned, if issued a yellow orange flame and soot then leave positive for this PS.
7. OTHER
Usually painted recycling logo with the number 7 in the center, as well as a note. For this type there are four kinds:
1. SAN - styrene acrylonitrile, 2. ABS - acrylonitrile butadiene styrene, 3. PC - polycarbonate, 4. Nylon.
Can be found in the foods and beverages such as sports water bottles, car parts, tools - household appliances, computers, equipment - electronic equipment and plastic packaging. SAN and ABS has a high resistance to chemical reactions and temperature, strength, stiffness, and the level of violence has increased. Usually found in the mixer bowl, wrapping flasks, dishes, cutlery, coffee filter, and toothbrush, while the ABS is commonly used as pipe material and lego toys.
Is one of the plastic material is excellent for use in packaging food or beverages.
PC - or polycarbonate can be found in baby bottles, toddler cups (sippy cup), polycarbonate drinking bottles, and cans of food and beverage packaging, including cans of infant formula. Can remove the main material is bisphenol-A into food and beverages that may damage the hormone system, the chromosomes in the ovaries, decreased sperm production, and alter immune function. It is advisable not used to place food or beverages
Ironically bottle is very likely to have the heating process, whether it be for the purpose of sterilization by boiling, microwave, or pour boiling water or hot water
From the above explanation we should be able to distinguish between plastic materials which are safe and which should be disposable eg
If the codes 1, 3, 6, and 7 (PC) must be used disposable because it has a chemical hazard.
If the code 2, 4, 5, and 7 (SAN or ABS) can be safely used.
Here are some tips:
If we often buy fried food on the street, try not directly included crackle, because the black dye contained in the crackle was exposed to heat, can be decomposed and degraded to form toxic radicals are harmful substances for health because it causes the body cells grow out of control that is cancer. Mending wrapped in banana leaves, it's definitely more secure, heheheee
For baby bottles are made better use of glass or plastic type 4 or 5.
For baby cup is better to use a stainless steel or plastic type 4 or 5
For the pacifier is better to use a silicone because it does not remove a carcinogenic substance as the dot-latex material.
Do pake baby milk bottles and baby cups (holes isepannya so) fueled the type 7 PC.
If the use made of polycarbonate plastic that we can not avoid, we do not store water in hot conditions at that place.
Avoid using plastic bottles (mineral water over and over - over for a drink can), if that is I just realized after writing kalo kayak gini tuh wrong behavior, so other alternatives must nyari hehehe, hopefully that can read this paper will know the risks ..
Do not use plastic for ngemas oily or fatty foods.
Wrap food in banana leaves wrapped in plastic or paper before either when heated in the microwave.
Prevent the use plastic plates and utensils for cooking, mending pake of stainless steel, ceramics, glass, and wood.
Well this is the last we have to tell your friends - friends or everyone around us on this information, Okey ..
May be useful.
