Hand feel is a polymer blend decision
LDPE feels soft and forgiving; HDPE adds spring and chemical resistance; LLDPE tweaks toughness. Consumers read quality from snap-back and wall collapse—often before they read ingredients.
Temperature changes everything
Modulus shifts in cold bathrooms versus hot warehouses. Prototype at both ends of your distribution climate, not only at 23 °C.
Formula migration still rules
A stiff tube that looks premium is worthless if actives migrate into the wall. Pair mechanical trials with weight-loss and extractables thinking appropriate to your category.
Conclusion
Specify PE blends against both sensory targets and chemistry. The right tube feels right and stays lawful after months beside a steam shower.
