1 Polyethylene terephthalate (PET or PETE)
Polyethylene terephthalate (pet or pete) is one
of the most common types of plastics and is
commonly found in bottle of soda, juice, water,
cough syrup and jars of peanut butter. The
bottoms of these containers are usually
stamped with the chasing arrow symbol and the
number 1, the code for PET.

Why is Pet so popular?
● Pet plastic is naturally, colorless and highly
transparent.
● Pet plastic is strong, lightweight,
shatterproof, and has excellent barrier to
gas, alcohol, and other solvents.
● Pet plastic is relatively inexpensive to
manufacture and is highly recycling.

Pet plastic in the world.
Pet plastic isn't the most used of the plastics. It
actually ranked number 3. But while it's not the
most use, PET is actually the most recycling
type of plastic in the world.

Unpigmented bottles are translucent, have good barrier properties and stiffness,and are well suited to packaging products with a short shelf life such as milk. HDPE hasgood chemical resistance, it is used for packaging many household and industrial chemicals such as detergents and bleach.

Product applications
People use HDPE for the bottles of milk, water, juice, cosmetic, shampoo, dish and laundry detergent bottles; yogurt andmargarine tubs; cereal box liners; grocery, trash and retail bags.

The polypropylene is also known as PP
It is a thermoplastic polymer used in a wide
variety of applications including packaging and
labeling, textiles (e.g., ropes, thermal
underwear and carpets), stationery, plastic
parts and reusable containers of various
types...

Market
-Following the slumping recession period and the slow revival state during the post-crisis years, the global market for polypropylene is seeing considerable demand increases as the key end-use fields expand production volumes. The total polypropylene market is not expected to witness complete and bashing downs in the coming 5 years: the polypropylene price is high and consumers are looking more rigidly for the material substitutes

Recycling
Polypropylene is recyclable and has the number "5" as its resin identification code:

Application-As polypropylene is resistant to fatigue, most plastic living hinges, such as those on flp-top bottles, are made from this material. However, it is important to ensure that chain molecules are oriented across the hinge to maximise strength.Very thin sheets of polypropylene are used as a dielectric within certain high-performance pulse and low-loss RF capacitors.

Low-density polyethylene
Excellent resistance (no attack) to dilute and concentrated acids, alcohols, bases and estersGood resistance (minor attack) to aldehydes, ketones and vegetable oilsLimited resistance (moderate attack suitable for short-term use only) to aliphatic and aromatic hydrocarbons, mineral oils, andoxidizing agentsPoor resistance, and not recommended for use with Halogenated hydrocarbons.LDPE is widely used for manufacturing various containers, dispensing bottles, wash bottles, tubing, plastic bags for computer components, and various molded laboratory equipment. Its most common use is in plastic bags.
