What is the reason stainless steel is lined underneath the handle?
When looking at the pot and noticing metal lined underneath the plastic handle, you ask this to confirm what practical purpose it serves.

It serves to prevent gas flames or heat from directly reaching the plastic handle, keeping the material from melting or becoming burning hot.
KOINU's classic two-handled pot uses polypropylene as the handle material, and both handles are finished with stainless steel lining underneath[1][2].
On direct heat appliances such as gas stoves or highlights, the flames and heat rising along the bottom reach the underside of the handles first[3]. Plastic-based materials retain less heat than metal and are comfortable to hold, but can melt or deform under direct high heat. The stainless steel lined underneath acts as a protective shield that deflects the hot heat rising from below, reducing damage to the handle or it becoming excessively hot[4].
It is a structure that allows you to concentrate on cooking without worrying about the handles being damaged by flames, not only on induction cooktops but also in direct flame environments where flames make direct contact[5]. After cooking is finished, it can be placed directly into a dishwasher for care[6].
Specific heat resistance standards regarding what level of flame power or temperature the stainless finish on the bottom of the handle can withstand have not yet been confirmed.
