The manufacturing process of plastic bottles happens at different stages. One of four types of plastic is used to produce plastic bottles. Usually, plastic bottles are made for the packaging industry for keeping foods & beverages, cosmetics, chemicals, and other items. Starting from 1 liter plastic bottle to 250Ml plastic bottle, you can find any size and shape of plastic bottles. The PET material is used for manufacturing water bottles, the PE is used to make rigid plastic bottles, and PP is used to make pill bottles. PC plastic is used to make refillable water bottles and other reusable containers. Before we dive into the manufacturing process, let’s learn more about the compositions of the materials.
What are plastic bottles made of?
What are plastic bottles made of?
As we have mentioned above, plastic bottles are made from PP, PC, PET, and PE. PE is available in two types; HDPE and LDPE, and here we will talk about how the materials affect the manufacturing process.
PET- it is a thermoplastic polymer that can be transparent or opaque depending on the composition of the material. Most of the plastic is produced from hydrocarbons. The PET creates long chains of molecules to form plastic bottles. The process is complicated, and to ensure the plastic is appropriate, many tests are done before the manufacturing process. Factors like pressure resistance, thickness, gloss, and transparency are also monitored.
LDPE/HDP- it is another thermoplastic that is used to manufacture water jugs, and milk bottles, ketchup bottles, spray bottles, and detergent bottles. Both HDPE and LDPE can be blow-molded, thermoformed, injection-molded, etc., and the LDPE is used for making squeezable bottles as it has lower strength compared with HDPE. HDPE is used to make durable and string pourable bottles. HDPE is usually white in its original form, and it is also used to make milk bottles.
PP- it is a low-density polymer with great thermoforming and injection molding properties. It is used to make transparent bottles so that customers can see the products easily. Due to the low viscosity, it is also suitable for molding applications.
PC- polycarbonate is a costly material, so it is only used to make end reusable bottles such as laboratory bottles and nursing bottles. You will come across a 1 liter plastic bottle of this material to a 5-liter bottle. PC offers high strength that makes it suitable for the bottles that must display the items inside the package. This material can withstand repeated washings as well and lasts for years.
How water bottles are made
How water bottles are made
The manufacturing of water bottles mainly depends on the material used in the making of the bottle. These bottles are mainly made from plastic, and the plastic can be made from PET, PVC, or PP. Sometimes the new PET is mixed with recycled PET before the material is melted at 260 degrees C. After that, they are reheated again to shape them further and cool down after that.
The manufacturing process of different types of bottles is from different types of materials. 1 liter plastic bottle for water requires different materials compared to a 1 liter plastic bottle for detergent or oil.
