Thermoforming pouch encapsulation process: Procter & GambleRecent Research Landscape

The technical lever is the precise thermal and mechanical sealing of polyvinyl alcohol films during high-speed pouch formation. This controls leak rates and dissolution kinetics for unit-dose delivery.

What technical problems is Procter & Gamble addressing in Thermoforming pouch encapsulation process?

Airborne particulate contamination

(18)evidences

The manufacturing of water-soluble products generates fine dust that poses safety risks and equipment fouling. Implementing extraction during the forming process prevents respiratory hazards and ensures product purity.

Premature pouch shell dissolution

(15)evidences

High active pastes often contain moisture or chemical components that can compromise the structural integrity of water-soluble films from the inside. Preventing unintended degradation ensures product stability and safe handling during storage.

Water soluble substrate structural failure

(8)evidences

The manufacturing of detergent pouches often results in mechanical tearing or thinning of water-soluble films and fibrous materials during high-speed forming. Preventing substrate rupture ensures containment integrity and shelf stability.
