What is the core difference between HygieSoft™ and standard plastic backsheets?

The core difference lies in vapor permeability and tactile comfort. Standard plastic backsheets act as complete, impenetrable barriers that trap heat and moisture, creating a “greenhouse effect” against the skin. In contrast, HygieSoft™ is a highly engineered composite laminate designed to breathe, keeping the wearer dry, cool, and comfortable without sacrificing leak protection.

Head-to-Head Comparison

The Old Standard

Standard PE Plastic Film

  • Non-Breathable: Traps humidity and body heat, leading to discomfort and increased risk of dermatitis.
  • Stiff & Noisy: Creates an embarrassing rustling noise during movement, unacceptable for adult incontinence products.
  • Plastic Touch: Feels artificial and clings uncomfortably to bare skin when sweating.
