Do you know what plastic recycling symbols mean? Every plastic bottle has the limit of uses,in this artcile we would like to inform and built comprehensive about the meaning of symbols in plastic bottle.If we used plastic bottle longer than the limit, it will bring bad effect for kidney function, cancer,liver , and so on.
Number 1 Plastics -- PET or PETE (polyethylene terephthalate)Found In: Usuallty used in every drink bottle such as soft drinks, mineral water bottles; and mouthwash bottles; peanut butter containers; salad dressing and vegetable oil containers; ovenable food trays.
Recycling: Pick up through most curbside recycling programs
Recycled Into: Polar fleece, fiber, tote bags, furniture, carpet, paneling, straps, (occasionally) new containers
Bottle with PET/PETE sign is SINGLE USE.Often used to keep hot water will cause melted polymer coating on the bottle that will realeasing the carcinogenic substances. Though the material is high demand by remanufacturers because it is contain the Antimoni Trioksida through the respiratory track from inhaling the dust. In the long term, this is will cause skin irritation and respiratory disorders.For female workers in recycle industry can improve the menstrual problems, miscarriage, and impaired growth in children untuil 12 monts .
Number 2 Plastics -- HDPE (high density polyethylene)
Found In: Milk jugs, juice bottles ( in jugs) ; bleach, detergent and household cleaner bottles; shampoo bottles; some trash and shopping bags; motor oil bottles; butter and yogurt tubs; cereal box liners, tupperware, folding chair, gallons of drinking water
Recycling: Pick up through most curbside recycling programs, although some only allow those containers with necks.
Recycled Into: Laundry detergent bottles, oil bottles, pens, recycling containers, floor tile, drainage pipe, lumber, benches, doghouses, picnic tables, fencing
HDPE carries low risk of leaching and have a stronger material properties, also is readily recyclable into many goods.Although HDPE is save to reuse, bottle of this sign is recommended in single use because the releasing of Antimoni Trioksida increasing over the time.
Found In: Window cleaner and detergent bottles, shampoo bottles, cooking oil bottles, clear food packaging, wire jacketing, medical equipment, siding, windows, piping, Cling Wrap.
Recycling: Rarely recycled; accepted by some plastic lumber makers.
Recycled Into: Decks, paneling, mudflaps, roadway gutters, flooring, cables, speed bumps, mats.
PVC contains chlorine, so its manufacture can release highly dangerous dioxins. If you must cook with PVC, don‘t let the plastic touch food. Never burn PVC, because it releases toxins.If the plastic touch the food or burn PVC it will cause the harm for kidney, liver, and weight problems.
Found In: Squeezable bottles; bread, frozen food, dry cleaning and shopping bags; tote bags; clothing; furniture; carpet
Recycling: LDPE is not often recycled through curbside programs, but some communities will accept it. Plastic shopping bags can be returned to many stores for recycling.
Recycled Into: Trash can liners and cans, compost bins, shipping envelopes, paneling, lumber, landscaping ties, floor tile.
LDPE is the (Thermoplastic / made from petroleum). Usually use for food storage box,and other plastic for food. Its mechanical properties is very strong, see-through, and fleksibel. At a temperature of 60 degrees is very resistant to chemical reactions, power protection against water vapor quite well. Can be recycled and proper for the goods that require flexibility but strong. Even though goods are made from LDPE is very difficult to destroy but they are really proper for food boxcause it is difficult to be chemical reacted.
Number 5 Plastics -- PP (polypropylene)
Found In: Some yogurt containers, syrup bottles, ketchup bottles, caps, straws, medicine bottles
Recycling: Number 5 plastics can be recycled through some curbside programs. Recycled Into: Signal lights, battery cables, brooms, brushes, auto battery cases, ice scrapers, landscape borders, bicycle racks, rakes, bins, pallets, trays
PP plastics has characteristics with transparent bottles that are not clear or cloudy.Polypropylene has a high melting point, and so is often chosen for containers that must accept hot liquid because stable at high temperature. It is gradually becoming more accepted by recyclers.For this moment this material is the BEST PLASTIC MATERIAL for food and drink .
Found In: Disposable plates and cups (styrofoam), meat trays, egg cartons, carry-out containers, aspirin bottles, compact disc cases
Recycling: Number 6 plastics can be recycled through some curbside programs.
Recycled Into: Insulation, light switch plates, egg cartons, vents, rulers, foam packing, carry-out containers
Polystyrene can be made into rigid or foam products -- in the latter case it is popularly known as the trademark Styrofoam. Evidence suggests polystyrene can leach potential toxins into foods. It is an aromatic polymer material that can emit styrene into food,can also be obtained from cigarette smoke, fumes and building construction materials. The material was long on environmentalists‘ hit lists for dispersing widely across the landscape, and for being notoriously difficult to recycle. This may cause cerebrovascular,can interfere with the hormone estrogen in women resulting in reproductive problems and growth of the nervous system.
Number 7 Plastics -- Miscellaneous (Other)Found In: Three- and five-gallon water bottles, ‘bullet-proof‘ materials, sunglasses, DVDs, iPod and computer cases, signs and displays, certain food containers, nylon, auto parts
Recycling: Number 7 plastics have traditionally not been recycled, though some curbside programs now take them.
Recycled Into: Plastic lumber, custom-made products
There are 4 type:
1. SAN – styrene acrylonitrile
2. ABS – acrylonitrile butadiene styrene
3. PC – polycarbonate
4. Nylon
SAN and ABS has a high resistance to chemical and temperature,normally exist in the mixer,wrapping flasks, dishes, cutlery, coffee filters, and toothbrush.
ABS is commonly used as lego and pipes
PC - or Polycarbonate can be found in baby bottles, toddler cups (sippy cup), polycarbonate drinking bottles and food packaging and beverage cans, including infant formula cans.
A wide variety of plastic resins that don‘t fit into the previous categories are lumped into number 7. A few are even made from plants (polyactide) and are compostable.
Polycarbonate is number 7, and is the hard plastic that has parents worried these days, after studies have shown it can leach potential hormone disruptors, chromosomes in the ovaries, decreased sperm production, and alter immune function because PC can release the main material , Bisphenol-A c into the food.
