1. PETE or PET
In general, these signs indicate the recycling logo with the number one in the center continue to exist after PET (polyethylene terephthalate) in the triangle. It is used for plastic bottles, colored / transparent / translucent bottles of mineral water for example, bottles, juice bottles, and almost all other drinks. It should be noted for the type of PET or PETE bottles used once, because if too often used to store frequently used especially warm or hot water can cause the polymer film on the bottle melt and release a substance carcinogenic in the long term can cause cancer.
For workers involved in the processing of PET and recycled PET plastic must be vigilant, as it is in fact the PET, a material called antimony trioxide, antimony trioxide materials that can enter the body through the respiratory system is caused by inhalation of dust containing these compounds. In the long term, lead to skin irritation and respiratory tract. For workers in these compounds can improve menstrual problems and miscarriage, childbirth, their children are likely to slow growth until the age of 12 months. In the world of the majority of PET fibers (60%), textile materials are usually used with polyester PET bottle packaging by 30%.
2. HDPE
In general, these signs indicate recycling logo number two in the center and the positions of HDPE (High Density Polyethylene) below the triangle. Typically used for white milk milk bottle, plastic containers, gallons of drinking water, folding chairs and others – others. material properties of HDPE much stronger, hard, opaque and resistant to high temperatures. Although HDPE is a plastic material that are safe to use because of its ability to prevent chemical reaction between the plastic containers made of high density polyethylene with a meal or drink is only recommended for testing, but only because of the antimony trioxide release USE ONCE compounds continued to increase over time.
3. PVC
Usually written in red with the number 3 in the center accompanied by a letter V. Significance of the V is pointing PVC (polyvinyl chloride) is the most difficult type of plastic for recycling. It is often found in plastic wrap (film), and a bottle – bottle. If PVC is used for food is potentially dangerous to the kidneys, liver and body weight.
4. LDPE
Usually represented by the recycling logo in the writings of the Middle Ages and fourth digit LDPE. Low Density Polyethylene LDPE itself means that the type of chocolate plastic (thermoplastic / from oil), which is normally used for food, plastic containers and bottles – bottles of soft. The mechanical properties is very strong, transparent, flexible and low fat content of the surface at a temperature of 60 degrees is very resistant to chemical reaction, the power of protection against water vapor is just, can be recycled, and goods – goods that need flexibility but strong. Products in LDPE is very difficult to destroy, but good place for food because it is difficult to react chemically with foods that are filled with this material.
5. PP
In general, emergency logo, painted with the number 5 in the center, and the development of PP. Polypropylene PP represents, its features are transparent bottles that are not clear or cloudy. This material is stronger and lighter with a low penetrating power of steam, grease-resistant stable at fairly high temperatures and bright. This material is the best plastic material, good place for food and beverages.
6. PS
Usually represented by the recycling logo in the center of six figures, and writing the PS. Usually used to put food on Styrofoam cups, and others – others. PS is polystyrene, which is an aromatic polymer that can release styrene in food ingredients when eating, it is moving. Besides restaurants, styrene can also be obtained from cigarette smoke, smoke, vehicles and building materials. This material should be avoided as dangerous to health than the brain, can disrupt the hormone estrogen in women causes reproductive problems and nervous system growth. The material of this kind is difficult to recycle, even if it can be recycled requires a long and old. Another way to identify the content of PS in the container that does not appear in the score that is most attached to the flames, if issued a yellow and orange flames, leaving the soot was so positive for PS.
7. OTHER
Usually painted recycling logo with the number 7 in the center, and a note. For this type, there are four types of
1. SAN – styrene acrylonitrile
2. ABS – Acrylonitrile-butadiene-styrene
3. PC – polycarbonate
4. Nylon.
Can be found in places such as food and drink bottles of water sports, car parts, tools – equipment, computers, equipment – electronic equipment and plastic packaging. SAN and ABS has a high resistance to chemical reaction and temperature, strength, stiffness, and the level of violence has increased. Usually found in the blender, packaging bottles, plates, cutlery and coffee filter, and toothbrush, while the ABS is commonly used as material behavior and Lego toys. Is it the plastic is excellent for use in food packaging and drinks.
PC – or can be found in polycarbonate bottles, baby cups (cup), polycarbonate bottles and food packaging and cans of beverages including infant formula cans. Then remove the main material is bisphenol A in foods and beverages that may damage the hormone system, the chromosomes in the ovaries, decreased sperm production and damage the immune function. It is advisable not to use for storing food or beverages
Ironically bottle is very likely that the heating process, either for sterilization by boiling, microwave or pour boiling water or hot water
From the above explanation should be able to distinguish that one is sure of plastics and which should be available, for example
1. If this is coded 1, 3, 6 and 7 of PC () must be used for single use, because it has a chemical hazard.
2. If code 2, 4, 5 and 7 (SAN or ABS) can be used safely.
Here are some tips
1. If we buy often fried in the street, try not directly included kresek because the black dye contained in kresek were exposed to heat, can be decomposed and degraded to a radical form toxic substances hazardous to health because it leads body cells that grow out of control of cancer. Repair wrapped in banana leaves, lol.
2. If a bottle of milk to make tools that better use of glass or plastic type 4 or 5.
3. If, for mending pake Cup baby is stainless steel or plastic type 4 or 5.
4. Pacifier use the tools that silicon is not carcinogenic ngeluarin better because the point of latex.
5. Do not drink the bottle and baby pake (isepannya hole so) of seven types of computer.
6. If use is made of polycarbonate plastic that we can not, do not have enough in a state of Aer nyimpen hot right place.
7. Avoid using plastic bottles (water and more – a place to drink), but I just realized after writing a Gini tuh kayak if my behavior is bad, so other alternatives jejeje kudu Nyari, I hope others are addressing the child can read this and you know the risk ..
8. Ngema pake not oily or greasy plastic.
9. Cover food with banana leaves or paper wrapped in plastic before or when heated in the microwave.
10. Prevention of plastic sheeting used for cooking, covered, use the repair tools such as glass, stainless steel, ceramic and wood.
