5 Gallon PET Bottle Project

The 5-gallon (18.9L) water bottle is already common all across the USA in offices and factories. It is becoming increasingly common in Europe, and in areas such as Latin America, where tap water is undrinkable or non-existent, the 5-gallon bottle has found a market in domestic use. The potential for a 3-gallon domestic cooler is now being seriously examined, with the major water companies delivering direct to homes, bypassing supermarket distribution. The market is only waiting for one of the major domestic electrical equipment suppliers to take the first step.

The material used today for the 5-gallon bottle is overwhelmingly polycarbonate (PC). The material is, however, costly - much more so than PET, and hence only refillable bottles are produced. This also applies to PET bottles, which are currently produced principally on single stage machines outputting typically 100 bottles per hour. For the market to evolve at the desired rate for PET higher outputs will certainly be required.
