Here is the list of plastic materials/resin used to make plastic bottles.

High Density Polyethylene Bottles

HDPE is a naturally translucent and flexible material that can be classified in two groups.

Natural HDPE Bottles

It’s naturally white and translucent. Used to make Milk Bottles

Colored HDPE Bottles

Used to make Shampoo and Laundry Detergent Bottles.

The majority of plastic bottles utilize HDPE resins because they are inexpensive, impact & chemical resistant, and provide superior moisture barriers. HDPE is mostly used in the creation of milk and juice bottles but due to its chemical resistant properties, it can also be used to hold household chemicals and detergents. Pigmented or colored HDPE bottles have an enhanced fracture resistant property.

Low Density Polyethylene (LDPE) Plastic Bottles & Containers

Is comparable to HDPE in composition but more translucent. It is generally less rigid and chemically resistant than HDPE. Being a softer material, LDPE can be used for squeeze plastic bottles and other flexible applications like plastic film and grocery bags. LDPE is also used in the manufacturing of some flexible lids and bottles, as well as in wire and cable applications. LDPE is significantly more costly than HDPE.

Polyethylene Terephthalate (PET) Plastic Bottles

Is frequently used for plastic carbonated beverage and water bottles. PET is a type of polyester. Manufacturers use PET plastic to package products because of its strength, thermo-stability and transparency. Customers choose PET because it is inexpensive, lightweight, reseal able, shatter-resistant and recyclable. PET bottles are labeled with a resin identification code #1 PETE imprinted on or near the side or bottom of the container.
