In the field of heat patch manufacturing, not all products are the same. For Jiangsu Hanyao, excellent quality begins with our control to the most fundamental raw materials.
What is the secret behind a consistent heat patch?
It lies not in complex chemical formulations, but in the outer layer of non-woven fabric and composite film. Acting as the heat patch’s “respiratory organs”, non-woven fabric controls the rate of oxygen intake, thereby directly determining the speed of internal iron powder oxidation reaction. Most manufacturers on the market purchase their raw materials externally, which results in fluctuations in the heating curves across different product batches.
How do we control quality from the source?
We have introduced advanced production lines for non-woven fabric and composite films, enabling us to research and manufacture our core materials independently. Through this vertical integration, we can achieve:
- Precise Permeability Control: We have professional punching machines to adjust the fabric’s pore size, then the oxygen can enter evenly.
- Skin-friendliness: Our fabrics are spunlace fabric with specialized processing to keep exceptional comfort and flexibility, even during long-time wear and use.
- Zero difference on batch-to-batch: Each roll of our fabric used in production have been tested strictly, in case of any potential risks of uneven breathability.
Why is this part is crucial for our global partners?
When our partners choose our OEM/ODM services, they are purchasing more than just a heat patch, they are securing stability and reliability.
1. Long heating duration: Our technology ensures that the product performance can maintain an effective temperature over 12 hours.
2. Safety for users: Through precise temperature control, we can achieve a stable temperature curve, which greatly reduced the risk of burns caused by rapid chemical reactions.
3. Market competitiveness: Since we can produce raw material in house, so we have the unique advantage in cost control and technology barrier. And this will translate directly into price competitiveness and brand reputation for our partners in the end of market.
At Hanyao Medica, we believe that “only by controlling the source can define the standard”. If you are looking for a supplier that not only understands assembly but also strives for excellence from the very beginning raw materials, we would be your ideal choice.
