Product Overview
The C40 self heating knee patch is a disposable air-activated warming product designed for convenient heat application around the knee area.
The patch measures approximately 390 × 145 mm with a stated dimensional tolerance of ±10 mm. It provides approximately 5 hours of continuous warmth, with a continuous heating temperature above 45°C and a stated maximum temperature of no more than 60°C.
The heating layer contains iron powder, activated carbon powder, vermiculite, water-absorbing resin, food-grade salt and water. The product also includes wormwood, ginger, Eucommia ulmoides and frankincense essential oil.
A flexible non-woven structure and elastic knee-wrap design allow the patch to fit around the knee area. Each patch is individually packed for single use, with six individually packaged pieces supplied in one box.
The C40 is intended for personal warming and hot-compress applications rather than medical treatment. OEM and ODM requirements such as packaging design, branding, exterior presentation and selected product specifications can be reviewed according to project requirements.
