Polypropylene is often used for food containers, particularly those that need to be dishwasher safe. The melting point of polypropylene is very high compared to many other plastics, at 320°F (160°C), which means that the hot water used when washing dishes will not cause polypropylene dishware to warp. This contrasts with polyethylene, another popular plastic for containers, which has a much lower melting point. Polypropylene is also very easy to add dyes to, and is often used as a fiber in carpeting which needs to be rugged and durable, such as the carpet one finds around swimming pools or paving miniature golf courses. Unlike nylon, which is also often used as a fiber for rugged carpeting, polypropylene doesn't soak up water, making it ideal for uses where it will be constantly subject to moisture.

Polypropylene is not as sturdy as polyethylene, but it has benefits that make it the better choice in some situations. One of these situations is creating hinges from a plastic, such as a plastic lid on a travel mug. Over time, plastics fatigue from the repetitive stress of being opened and shut, and eventually will break. Polypropylene is very resistant to this sort of stress, and is the plastic most often used for lids and caps which require a hinging mechanism. original source

Polyvinyl chloride is one of the world's most widely used plastics. Its acceptance comes from the plastics versatility - it can be utilized in rigid compound or blended with plasticizers to produce flexible plastic grades.

Almost three-quarters of rigid PVC plastic produced goes into building and construction applications. Most is processed via extrusion into products such as pipe, siding, and window profiles. Packaging is another major market for PVC plastic. Rigid grades are blown into bottles and made into sheet for thermoforming boxes and blister packs. Flexible compounds are made into food wrap. Other markets for PVC plastics include wire and cable coating, flooring, garden hose, and toys. original source

Polystyrene is an inexpensive and hard plastic, and probably only polyethylene is more common in your everyday life. The outside housing of the computer you are using now is probably made of polystyrene. Model cars and airplanes are made from polystyrene, and it also is made in the form of foam packaging and insulation (StyrofoamTM is one brand of polystyrene foam). Clear plastic drinking cups are made of polystyrene. So are a lot of the molded parts on the inside of your car, like the radio knobs. Polystyrene is also used in toys, and the housings of things like hairdryers, computers, and kitchen appliances.

PET stands for polyethylene terephthalate, a plastic resin and a form of polyester. Polyethylene terephthalate is a polymer that is formed by combining two monomers: modified ethylene glycol and purified terephthalic acid.

PET is the type of plastic labeled with the #1 code on or near the bottom of bottles and containers and is commonly used to package soft drinks, water, juice, peanut butter, salad dressings and oil, cosmetics and household cleaners.

PET is a popular package for food and non-food products. Manufacturers use PET plastic to package products because of its strength, thermo-stability and transparency. Customers choose PET because it is inexpensive, lightweight, resealable, shatter-resistant and recyclable.

Recycled polyethylene terephthalate (RPET) can be used to make many new products, including fiber for polyester carpet; fabric for T-shirts, long underwear, athletic shoes, luggage, upholstery andsweaters; fiberfill for sleeping bags and winter coats; industrial strapping, sheet and film; automotive parts, such as luggage racks, headliners, fuse boxes, bumpers, grilles and door panels; and new PET containers for both food and non-food products. original source

Other (MIXED PLASTICS) This category is the "catch-all" designated #7. Depending on the manufacturer, similar products have no number. These items are seldom collected. Recycling them is impossible, with most contributing to landfills as trash. Avoid these plastics - recyclers can't use it and don't want it.

LDPE is an acronym for low-density polyethylene. This type of plastic can be identified in many products we use with the resin code, or recycling number, ?.

According to the American Chemistry Council (ACC), LDPE is primarily used in film applications because it is tough, flexible and relatively transparent. LDPE is also used to produce some flexible lids and bottles as well as in wire and cable applications.

The ACC reports that LDPE has an excellent resistance to acids, bases and vegetable oils. Its toughness, flexibility and relative transparency make it good for packaging applications requiring heat-sealing.

LDPE is used to make many thin, flexible products like plastic bags for dry-cleaning, newspapers, bread, frozen , fresh produce and garbage. Most shrink-wrap and stretch film is also made out of LDPE, as well as coatings for paper milk cartons and disposable beverage cups. Manufacturers also use LDPE to create thin container lids, squeezable bottles and some toys.

Most areas offer recycling for products made with LDPE and linear low-density polyethylene (LLDPE), which also features a recycling number ?. Like all other types of plastic, LDPE can take hundreds of years to decompose in the landfill, so products that are made exclusively of LDPE should be recycled if possible. Some areas don't offer recycling for plastic bags made from LDPE, but these can be reused instead.

HDPE (high-density polyethylene) plastic is a linear polymer (a polymer that does not branch or cross-link) generated from ethylene using a catalyzing process.

HDPE plastic has several applications, including packagingfor foods (milk and snacks, for example) andcleaners. It is also used for pipe fittings, trays and hinges.

High-density polyethylene plastics are suitable for several manufacturing processes

HDPE plastic is resistant to acids, bases, alcohol and vegetable oils, as well as being impact resistant. It is also resistant to sustained heat of about 110 degrees Celsius.

High-density polyethylene plastics have poor resistance to UV (ultraviolet) light. HDPE does not biodegrade in landfill settings, nor can it be composted.

HDPE is a recyclable material and is falls under No. 2 of the plastic resin code. Recycled HDPE is used in pallets, drainage pipes and packaging. original source
