Both self-heating product–what’s the difference between Medical Heat Patch and Regular Warmer? It lies an entire system of materials, temperature control, and certifications.
1. Material
Heat patches touch skin directly and belong to ⅡA class medical device.
Regular warmers mostly use regular fabrics and Medical heat patch must use medical-grade nonwoven fabric that strictly meets standards in the following areas:
| Biocompatibility: | Low allergenicity, passed skin irritation tests |
| Breathability and softness: | No stuffiness or friction during extended wear |
| No fluorescent agents/No harmful additives: | No fluorescent agents / No harmful additives |
We are the only one factory which can independently produces low-temperature medical-grade nonwoven fabric in China–controlling material safety and temperature stability from the fiber source.
2. Temperature
Medical heat patches are held to stricter temperature control standards:
| Precise temperature control: | Stable heating within a specific therapeutic range |
| Controlled temperature curve: | Prevents sudden high-temperature spikes that irritate skin |
| Predictable duration: | Sustained, even low-temperature heating ensures efficacy and safety |
| Targeted heat application: | Custom shapes concentrate heat precisely on the target area |
3. Certification
For products to enter overseas medical channels, certification is a mandatory threshold.
European Market:
Under the EU Medical Device Regulation (MDR 2017/745), the requirements include:
| Technical Documentation: | Complete technical files covering product design, material composition, temperature performance, and biocompatibility testing |
| Clinical Evaluation: | Literature research or clinical data demonstrating safety and intended therapeutic efficacy |
| Quality Management System: | Compliance with ISO 13485 quality management system |
| EU Authorized Representative: | Appoint an authorized representative based in the EU |
| UDI System: | Product must carry a Unique Device Identification (UDI) number |
| Declaration of Conformity: | Sign a declaration statement in compliance with MDR requirements and affix the CE mark |
Closing:
Every threshold crossed requires years of technical accumulation and sustained investment.
We are a heat patch factory with low-temperature medical nonwoven production + custom-shaped patch R&D capability + export compliance services-–committed to providing overseas markets with heating products that truly meet medical-grade standards.
