High active detergent pastes often suffer from poor solubility and residue formation in water-soluble films. Improving dissolution ensures full chemical release and prevents film staining on fabrics.

The keywords focus on sealing jaws and fibrous non-woven sheets within water-soluble dose articles. The technical challenge is ensuring structural integrity and leak prevention at the interface of surfactant-loaded fibrous materials during the heat or pressure sealing process.

High-concentration detergent formulations in unit dose formats often suffer from phase instability or incomplete dissolution due to limited surfactant solubility in low-water environments. Improving solubility ensures product clarity and rapid release during the wash cycle.
