How It Works

The preform is placed in the mold and then the actual beverage (or whatever product is to be bottled) is forced at high pressure into the preform, molding it into the bottle shape. This results in a filled bottle, ready for capping and labelling.

Reduced energy use

A significant reduction in the energy required for bottling is achieved by eliminating the need for compressed air. For standard blow molding, the air compression cycle is only 35% to 40% efficient and consumes approximately 70% of the total amount of electricity used in the blow molding process. LiquiForm® uses much less electricity to hydraulically drive...

Reduced waste, downtime and labor

The one step LiquiForm® process represents a reduction in the waste, downtime and labor associated with operating and supporting two separate machines, particularly in reducing change-over and maintenance waste.

Lower capital cost and reduced factory footprint

Standard bottle making and filling operations are typically performed by two separate pieces of equipment. The LiquiForm® process requires a footprint which compares to a traditional blow molder, dramatically reducing floor space requirements.

Optimised bottle lightweighting and definition

The LiquiForm® process optimises PET bottle design both in terms of lightweighting and potentially sharper bottle definition (because better pressure control and material distribution is possible with liquid instead of air which allows for minimum wall thicknesses).

Reduced greenhouse gas emissions

The lightweight bottles possible with LiquiForm® means filled bottles weigh less, reducing the greenhouse gas emissions associated with transportation. For supply chains using converter suppliers, the transportation of unfilled containers between factories is also eliminated.

Reduced risk of bottle damage or contamination

For supply chains using converter suppliers, the transportation of unfilled containers between converting suppliers and customers’ warehouses is eliminated. This reduces the inherent risk of damage and the risk of contamination in moving and warehousing unfilled bottles across multiple manufacturing sites.
