Manufacturing Process of Coca-Cola Plastic Bottles

Overview

500 billion plastic bottles are produced globally each year.
Coca-Cola bottles are primarily made from polyethylene terephthalate (PET), derived from crude oil.
50% of Coca-Cola products are packaged in plastic bottles.

Crude Oil Transportation:
- Transported by tankers that carry up to 2 million barrels.
Refining Crude Oil:
- Crude oil contains various hydrocarbons and impurities (e.g., salt, sulfur, metals).
- Is separated by heating to over 400°C in a distillation unit.
- Results in different fuel condensates; lighter fuels like ethylene rise to the top.
Plastic Production:
- Ethylene is solidified into small polyethylene pellets, used to make plastic bottles.
- Daily, seven trucks deliver 25 tons of pellets to factories.

Injection Molding:
- Polyethylene pellets are melted at 290°C and injected into molds to create bottle preforms.
- 15 machines produce over half a million preforms per hour.
- Preforms have a neck support for handling.

Heating and Inflating Preforms:
- Preforms heated to 115°C to soften.
- Inflated using high-pressure air into bottle molds.
- Molds are cooled with a liquid system, producing 10,000 bottles per hour.

Cooling and Transportation:
- Bottles cooled to solidify and stabilize shape.
- Transported via air-powered conveyor over a kilometer to the pallet area.

Depalletizing and Cleaning:
- Bottles aligned by a depalletizer.
- Bottles cleaned with ionized air.
Filling and Labeling:
- Filled with carbonated soda in a pressurized environment (cold at 2-3°C).
- Labels applied after cleaning.
- 800 bottles filled per minute; bottles sealed with caps.
