The meaning of the code numbers in the Triangle in plastic packaging

The meaning of the code numbers in the Triangle in plastic packaging
Maybe we often come across a sign or logo in a triangle on the bottom of plastic bottles, commonly used to drink mineral water or any other liquid. Inside the triangle is numbers ranging from 1 to 7.

Logo or mark of the triangle is a code issued by The Society of the Plastic Industry in 1998 in the United States and adopted by the institutions of the system development of code, such as the ISO. Here is the meaning of the numbers contained in the Triangle Code commonly used in plastic packaging:


1. PET or PETE (Polyethylene Ethylene Terephalate)

The logo usually printed on plastic bottles, colored clear/transparent/opaque such as mineral water bottles, juice bottles, food containers and almost all other beverage bottles. Bottle type of PET/PETE is recommended only once. When used too often, let alone used to store heat, let alone warm water would result in a layer of polymer on the bottle it will melt and give off a substance is carcinogenic (may cause cancer) in the long term.

PETE material is dangerous for workers that are associated with the processing of recycled bottle or bottle of PETE. Making PETE using compound antimoni trioxide. These compounds can enter the body through the respiratory system by inhaling air. Often inhale the compound could lead to irritation of the skin and the respiratory tract. For women, these compounds increase menstrual problems and miscarriages. When giving birth, the child is likely to experience slow growth up to the age of 12 months.


2. the HDPE (High Density Polyethylene)

The triangle with the number two in the Middle, commonly used for milk bottle white milk, tupperware, gallons of drinking water, folding chair, and others. Types of HDPE plastic bottles have the properties of materials that are stronger, hard, opaque and more durable against high temperatures. It is one of plastic materials that are safe to use because of its ability to prevent a chemical reaction between the plastic packaging made from HDPE with food/beverages be labeled with. Just as the PET, HDPE also recommended wearing disposable just because the release of compound antimoni trioxide continues to increase over time. This type can also be used for the material back to the floor tiles, drainage, new HDPE bottles, pipes, and others.


3. PVC (Polyvinyl Chloride)

PVC (Polyvinyl Chloride) can be found on the plastic wrap (cling wrap), and bottles. The reaction that occurs between the PVC with foods that are packed with the plastic is potentially dangerous to the kidneys, liver and body weight. These materials contain chlorine and will produce toxins if burned. PVC should not be used in preparing food or food packaging. This material can be processed back into mudflaps, panels, mats, and more.

PVC contains DEHA (diethylhydroxylamine) that are harmful to the body, usually this material react with foods that are packaged in plastic made from PVC. DEHA can this mild temperatures-15 ° C.


4. LDPE (Low Density Polyethylene)

LDPE (low density polyethylene) that Brown type plastic (thermoplastic/made from petroleum), commonly used for food packaging, plastic bottles, the soggy, clothing, furniture, and others.

Types of mechanical properties of LDPE has a strong, transparent, flexible and a bit fatty surface at a temperature of 60 degrees is very resistant to chemical reaction, power protection against moisture are categorized as good, recyclable and good for items that require flexibility but strong. Goods made of LDPE is difficult, but still good for the food because it is difficult to react chemically with foods that are packaged with this material. LDPE, can be recycled in many ways.


5. PP (polypropylene)

Have characteristics which are not transparent, clear or cloudy. Polypropylene is more powerful and lighter with translucent power low steam, good resistance to fats, stable against high temperature and quite shiny. Types of PP (polypropylene) this is the best choice of plastic materials, particularly for food and beverage venues such as place of storing the food, drink and most important bottle drinking bottles for babies.

Look for the code number 5 when buying goods made of plastic for storing packaging of various food and beverages. PP can be processed back into brooms, trays, rakes, and others.

6. PS (Polystyrene)

This material, commonly used as a food ingredient styrofoam, place disposable drink, and others. Polystyrene is a polymer of aromatic that can dispense the ingredients styrene into food when the food is in contact. Besides food, styrene also can be obtained from the r0k0k smoke smoke, vehicles and construction materials.

This material should be avoided, because other than hazardous to health the brain, Estrogen hormones in women which result in reproductive problems, nervous system and growth and, also because of this difficult material recycled. No matter when this material is recycled, the process requires very long and long. This material can be identified with the code number 6, but if these numbers code not listed on the packaging of plastic, this material can be identified by way of burnt (the way the last and best avoided). When burned, it will issue the primary-colored fire, leaving soot.

In addition, these materials contain benzene, a cancer-causing substance and should not be burned. These materials are processed back into isolation, packaging, plant beds, and others.


7. OTHER (Polycarbonate)

Types of plastic materials for the 7 Other there are 4 kinds, namely: SAN (styrene acrylonitrile), ABS (acrylonitrile butadiene styrene), PC (polycarbonate), and Nylon.

This material can be found on the place of food and beverages such as bottled drinking sports, car parts, household appliances, computers, electronics, tools and plastic packaging.

SAN and ABS has high resistance against chemical reaction and temperature, strength, stiffness, and the level of violence has increased. Usually found in the bowl of a mixer, wrap the flask, plates, dinnerware, coffee filter, and brush your teeth, while the ABS are usually used as toys lego and pipes. It is one of a very good plastic material for use in the packaging of food or drink.

PC Polycarbonate or name can be found on the baby's milk bottle, glass children the toddler (sippy cup), drinking bottles and cans, polycarbonate food and beverage packaging, including cans of infant formula. The PC can issue its material Bisphenol-A into food and drinks that could potentially damage the system hormones, chromosomes on the ovaries, decreased sperm production, and change the function of the immune system. It is recommended not to be used for food or drink.

The meaning of the code numbers in the Triangle on the packaging PlastikIronisnya bottle milk is very likely to experience the process of warming, whether it be for the purpose of sterilization by means of boiling, heated with microwaves, or dituangi boiling water or hot water.

Not all plastic number 7 is the polycarbonate, even some vegetable-based. Palikarbonat is still a debate in the last few years, because it was discovered at the time wash BPA (bisphenol A), the subject of hormone disruptor pregnancy and fetal growth. [source: al-atsariyyah/kiddyworld/islampos]
