Product Overview
The A40 self heating neck patch is a disposable wearable warming product designed for convenient neck-area heat application.
The patch measures approximately 490 × 85 mm with a stated dimensional tolerance of ±10 mm. Product materials specify continuous heating for approximately 5 hours, with the operating temperature maintained above 45°C and a stated maximum temperature of no more than 60°C under the applicable product conditions.
The heating layer contains iron powder, activated carbon powder, vermiculite, edible salt, water-absorbing resin and water. The product also includes herbal ingredients such as wormwood, ginger and Chuanxiong, together with frankincense essential oil.
A flexible non-woven structure and adhesive neck-wrap design allow the patch to be positioned directly around the neck area. Each patch is individually packed for single use, with four individually packaged pieces supplied in one retail box according to the available product specification.
The A40 is intended for personal warming and hot-compress applications rather than medical treatment. OEM and ODM requirements such as exterior design, packaging, branding and selected product specifications can be reviewed according to project requirements.
