Fibrous non-woven sealing interface: Procter & GambleRecent Research Landscape
The technical lever is the engineering of a nonwoven fibrous sheet to facilitate thermal or mechanical sealing in water-soluble substrates. This controls the structural integrity and dissolution profile of unit dose packaging.
What technical problems is Procter & Gamble addressing in Fibrous non-woven sealing interface?
Premature film dissolution failure
The interface between fibrous non-woven layers and water-soluble films often suffers from insufficient seal integrity when containing concentrated liquids. Ensuring a robust barrier prevents accidental leakage and maintains structural stability during storage.
Inadequate fibrous interface seal integrity
The keywords indicate a focus on the interface between sealing jaws and fibrous non-woven sheets in water-soluble articles. The primary technical challenge is ensuring a robust, leak-proof bond in porous fibrous materials that must remain soluble yet contain surfactants.
