Recently Food and Drug Supervisory Agency (BPOM) deliver the results to monitor and evaluate the types of plastic bags that currently many kresek circulated widely on the market. That the materials used to make plastics kresek comes from recycled material of unknown origin.
Concerns on the use of plastic products that relate directly to human food become reasonable to note, given the dangers of chemical substances in a plastic product which when consumed by the body can cause cancer.
In addition to harmful foods, the use of plastic products like bags kresek, straws for human life is also very harmful. Because the content of plastic materials are not easily explained by the nature, or it takes over 1000 years for nature to be mengurainya.
If it's plastic that's not good for health, whether there are signs pengenalnya? It turns out there is, And that has already been set and set internationally, so that anywhere in this world the same codes and symbols.
This code is issued by The Society of Plastics Industry in 1988 in the United States and was adopted also by the institutions that developed the code system, such as ISO (International Organization for Standardization).
In general the signs are located at the base, triangular-shaped, inside the triangle will have a number, and name the type of plastic below the triangle, with the examples and explanations as follows:
1. PET - polyethylene terephthalate
Usually, at the bottom of plastic bottles, recycled logo printed with the number one in the center and writing PETE or PET (polyethylene terephthalate) under the triangle
Ordinary plastic bottles used for clear / transparent / translucent like mineral water bottles, juice bottles, and almost all other beverage bottles.
The majority of the world's PET plastic material for synthetic fibers (about 60%), in textiles commonly called polyester PET (bottle packaging materials 30%) Bottle Type of PET / PETE is recommended USE ONLY ONCE, why? Answered by this article: If used too often, I used to keep warm let alone hot water, will result in the polymer film on the bottle will melt and release carcinogenic (can cause cancer)
In making PET, using a material called antimony trioxide, which is dangerous for the workers associated with the processing or cycle repeats, because the antimony trioxide enters the body through the respiratory system, which is caused by inhaling dust containing these compounds. Contamination of these compounds in a long period will experience: skin and respiratory tract irritation.
For female workers, these compounds improve menstrual problems and miscarriage, even when giving birth, their children are likely to experience slow growth until the age of 12 months.
2. HDPE - High Density Polyethylene
* Generally, at the bottom of plastic bottles, recycled logo printed with the number two in the middle, and the writings of HDPE (high density polyethylene) under the triangle.
* Regular milk bottles used for white milk, tupperware, drinking gallons of water, folding chairs, and others.
* HDPE is one of the plastic material that is safe to use because of its ability to prevent chemical reaction between the plastic containers made from HDPE with food / drink quizzes.
* HDPE has a much stronger material properties, hard, opaque and more resistant to high temperatures.
* Same as PET, HDPE is also recommended only for one use, since the release of antimony trioxide compounds continued to increase over time
3. V - Polyvinyl Chloride
Recycling logo printed (sometimes red) with the number 3 in the middle, and writing V - V that means PVC (polyvinyl chloride), which is the most difficult types of plastics recycling.
* Plastics can be found in the plastic wrap (cling wrap), and bottles.
* PVC contain DEHA, which can react with foods that are packed with plastic is made from PVC during direct contact with food such as DEHA is melted at a temperature of-15oC.
* The reaction between PVC and plastic food that is packaged with this potentially dangerous for the kidneys, liver and body weight.
* We should seek alternative wrapping other foods that do not contain any softener materials such as plastics made of polyethylene or natural materials (eg banana leaf).
4. LDPE - Low Density Polyethylene
Recycling logo printed with the number four in the middle, and writing LDPE
- LDPE (low density polyethylene) is the type of brown plastic (thermoplastic / made from petroleum), normally used to place food, plastic packaging, and bottles of soft.
* Mechanical properties of LDPE plastic is strong, slightly translucent, flexible and slightly greasy surface. At temperatures below 60oC is very resistant against chemicals, power protection against water vapor is fair, but less good for other gases such as oxygen.
* Plastics are recyclable, both for goods that require flexibility, but strong, and has good resistance to chemical reactions.
* Products made from LDPE are difficult to destroy, but still a good place for food because it is difficult to react chemically with foods that are packed with this material.
5. PP - Polypropylene
Recycling logo printed with the number 5 in the center, as well as writings PP
- PP (polypropylene) is the best choice for plastic materials, particularly related to food and beverages like to store food, drink bottles and most drink bottles for babies.
* Characteristics are usually transparent bottles that are not clear or cloudy. Polypropylene is stronger and lighter with a low vapor penetrating power, good resistance to fat, stable against high temperature and enough shiny
* Find the 5 digit code when buying goods made from plastic containers to store various foods and beverages.
6. PS - Polystyrene
Recycling logo printed with the number 6 in the middle, and the writings PS
- PS (polystyrene) was discovered in 1839, by Eduard Simon, a pharmacist from Germany, by accident.
* PS is usually used as an ingredient where to eat styrofoam, disposable drinking cups, and others.
* Polystyrene is an aromatic polymer that can release styrene material into the food when the food is touching.
* In addition to food places, styrene can also be obtained from cigarette smoke, smoke, vehicles and building construction materials.
* This material should be avoided, as dangerous to health than the brain, interfering with the female hormone estrogen which results in reproductive problems, and growth and nervous system, also because these materials difficult to recycle. Even if recycled, this material requires a very long process and duration.
* This material can be identified by a six digit code, but 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 leave soot.
7. OTHER
Recycling logo printed with the number 7 in the center, as well as by a note
- Other (SAN? Acrylonitrile styrene, ABS - Acrylonitrile butadiene styrene, PC - polycarbonate, Nylon)
* Can be found at places such as food and drink sports drink bottles, car parts, household appliances, computers, electronic appliances, and plastic packaging.
* PC - Polycarbonate can be found in baby bottles, toddler cups (sippy cup), polycarbonate drinking bottles and food packaging and beverage cans, including cans of infant formula.
* Able to 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 to be used to place food or drink because of Bisphenol-A can migrate into the drink or food if the temperature is raised due to heating. 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.
* SAN and ABS has a high resistance to chemical reaction and temperature, strength, stiffness, and the level of violence has increased.
* There is usually at the mixer bowl, wrapping flasks, dishes, cutlery, coffee filter, and toothbrush, while the ABS is commonly used as pipe material and lego toys.
* SAN and ABS plastic material is one which is very good for use.
We must be wise in the use of plastics, especially plastics with codes 1, 3, 6, and 7 (particularly polycarbonate), all of which have a chemical hazard. This means that the plastic tidah with other code completely safe, but need to be studied further. So, if we must use plastic, will be safer when using plastics with codes 2, 4, 5, and 7 (except polycarbonate) whenever possible. If there is no plastic code on the container, or if the type of plastic is not clear (eg, code 7, which has not always been in the form of polycarbonate), the safest way is best to contact the manufacturer and ask them about the type of plastic used to make these products.
Tips
1. Prevent the use of baby bottles and baby cups (with holes penghisapnya) made from polycarbonate, try to choose and use baby bottles made from glass, polyethylene, or polypropylene. Use baby cups made from stainless steel, polypropylene, or polyethylene. To dot, use a silicone based, as it will not release carcinogenic substances as in the dot made from latex.
2. If the use made of polycarbonate plastic can not be prevented, do not store food or drinking water in hot conditions.
3. Avoid using plastic bottles for storing drinking water. If you use plastic bottles made from PET (code 1) and HDPE (code 2), can not be prevented, only use disposable and immediately spent for the release of antimony trioxide compounds continued to increase over time. Alternative materials that can be used are stainless steel or glass bottles.
4. Prevent heat food packaged in plastic, especially in the microwave oven, which can cause the chemicals contained in the plastic off and react with the food faster. This could happen if the plastic containers used for packaging oily or fatty foods.
5. Wrap the food first with banana leaves or paper before wrapped in plastic wrap when it will be heated in a microwave oven.
6. Try to use containers made of fabric for carrying vegetables, food, or groceries and use packaging made from stainless steel or glass to keep food or beverages
7. Prevent the use of plastic plates and cutlery for cooking. Use cutlery made from stainless steel, glass, ceramics, and wood.
8. Implement, deploy and invite everyone in our homes, offices, schools, campuses, and anywhere to find out this information and implement it in everyday life.
9. Ask the government to issue a policy with respect to plastic, as has been done by the Regents of Wakatobi, Ir Hugua, in order to rescue the marine ecosystem in the Wakatobi. As known, Wakatobi has the highest coral reef ecosystems and the best in the world today.
The danger to health is:
Most plastics such as PVC, so as not to be rigid and brittle material added with a softener (plasticizers). Some examples of softener is epoxidized soybean oil (ESBO), in (2-ethylhexyl) adipate (DEHA), and poliklorin biphenyls (PCBs) used in the packaging industry and food processing.
Softener materials such as PCBs are now banned its use because it can cause tissue death and cancer in humans (carcinogenic). Signs and symptoms of this poisoning of pigmentation in the skin and the lump-lump, stomach disorders, as well as arms and legs limp. While in pregnant women, resulting in the death of a baby in the womb and birth defects.
Other softener ingredients that can cause problems is DEHA. DEHA has activity similar to the hormone estrogen (female hormone in humans). Based on the results of tests on animals, DEHA could harm the hybrid system and produce a defective fetus, in addition to cause liver cancer. To avoid the danger that might happen if every day we are contaminated by DEHA, then we should look for alternative wrapping other foods that do not contain any softener materials such as plastics made of polyethylene or natural materials (eg banana leaf).
Another danger that can threaten our health if we burn the material is made of plastic. Burning plastic can bring its own problems for us. Burnt plastic will release toxic fumes which when inhaled can cause sperm become infertile and fertility disruption. The burning of PVC will issue DEHA which can disrupt the balance of the human hormone estrogen. It also can cause chromosomal damage and cause the babies born in a state of disability.
ESBO softener ingredients (epoxidized soybean oil) is also commonly used as insecticides. So far, this softener material danger to human health has not been there / in the research. As for the environment, ESBO able to kill zooplankton, and this has resulted in the disruption of the food chain of marine animals. It will also impact on disturbance source of protein, especially fish, to humans.
