Influenced by recycling advocates throughout the United States, introduces the Community industry plastics, Inc. resin identification coding system. It was in 1988 when setting this kind of separation (or grouping) plastic resin is easier to recycle the company sorts them and that the waste management system in a more systematic, was introduced.
The guidance in the use of recycling numbers
Plastic industry community in cooperation with the Federal Trade Commission (FTC) approved the following guidelines when using the code:
This is in accordance with the legislation in the 39 countries where the code should be used in bottles and rigid container. This is used to identify the content of resin (plastic type). Code, is currently assisting in the management of waste and recycling activities, does not affect the well-known product sales.
The code should, in any manner, never changes. No additional markings such as "recycled" may be placed around the symbol, also there should be a claim of any product recyclability placed anywhere near it.
½ "Symbol, as it would fit, it must be established or permanently imprinted on all liter container 8 ounces 5 litre capacity >
The placement of the symbol should be as close as possible to the center of the bottom of the container
To help You recycle efficiently, below are the 6 different symbols are useful in creating your own household waste management and a good description of plastic articles for recycling.
1 pet (PETE)-pet poly (ethylene terephthalate) is clear and hard resin which gases and water vapor can contain. It is often used in bottles and another injection molded products container. This Resin is a good candidate for recycling if they come in large volume in the waste management system, in the form of bottles for drinks, ketchup, beer, jam, jam, etc. Key industries to recycle these for important applications such as textiles, carpets, film, ink cartridges and moldings.
2 HDPE high density polyethylene-HDPE is commonly found in May different types of plastic bottles. High resistance to chemicals makes it packaging materials households and industrial materials such as detergent, shampoo, conditioner, bleach, etc. Proper waste disposal, namely, apart, will have these items for recycling and plastic shopping bags, wire and cable covering, reusable shipping containers, etc.
3V poly (vinyl cloride)-known as PVC, these can be categorized into two groups, namely, the rigid and flexible materials. While the use of containers is also highest for recycling is desirable, they have many industrial and domestic applications. .
4 LDPE low density polyethylene-which are typically found in film applications due to the relative toughness, using transparent and flexible.
a total of 5 PP-pp-it's good for the liquid is so hot as it has excellent chemical resistance and strong materials. An excellent example would be Tupperware products (which have their own recycling system), diapers, caps and closures, etc.
6 PS-polystyrene-this is a very versatile plastic materials that can be rigid or foamed. For example, cups of coffee, bread, styrofoam insulation, etc.Polystyrene can also be combined with a rubber to produce high-impact polystyrene, which is good for applications which require toughness.
Other 7-this means that the package is made up of different types of resins that are not included in any of the six above, or which is usually a package which is a combination of the code.
