What Types of Plastics Used to Make Bottles
Bottles are in use for many year different types of materials have been used to make bottles like glass bottles, metallic bottles/containers and now plastic bottles are capturing the market. Where ever you go in your daily life you will see plastic bottles or containers everywhere. Plastic bottles are found in stores, shops, homes, offices, workplaces, schools, bars, café shops, bathroom, and bedroom etc. Plastic bottles & containers that are designed for packaging can be made from a variety of materials and can be fashioned into an almost unlimited array of shapes and sizes. The choice of plastic will vary based upon a specific packaging application or use.
A misconception regarding plastics and plastic bottles
Approximately for every person, not linked to plastic field – all the plastic material are same and all the bottles are made with same types of material this is not true.
What characteristics should I be aware of when purchasing a plastic bottle or container?
- Shelf Life
- Oxygen Barriers
- Moisture Barriers
- Load Strength
- Impact Resistance
- Temperature Endurance
- Environmental Responsibility
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.
