Description
For Part 140300, the central question is how the collapsible tube behaves in the assembled package. Commercial approval should reflect filled-package testing under realistic processing and distribution conditions. Wall structure, head design, orifice, and formula rheology determine squeeze force, recovery, and product evacuation. Likely development programs include skin care, hair care, sun care, oral care, and personal care. This keeps sourcing decisions tied to measurable package requirements.
