Assessing Heat Patch Inner Packaging Oxygen Permeability

Assessing Heat Patch Inner Packaging Oxygen Permeability

Product catalog summary

Introduction
Heat patches are designed for personal comfort or therapeutic purposes, providing warmth through an exothermic reaction. The effectiveness of these patches is influenced by the oxygen permeability of their inner packaging materials, which affects the patch's temperature and heat delivery duration.

Methodology
The study uses the differential pressure method to measure the oxygen permeability of heat patch inner packaging. This method is suitable for materials with high oxygen permeability and involves creating a pressure difference across the material to measure gas diffusion. The Labthink C106H Gas Permeability Test System, compliant with international standards (GB, ISO, ASTM), is employed for this purpose.

Results
A non-woven fabric sample used in heat patch packaging was tested, revealing an oxygen transmission rate of 7.634 × 10⁷ cm³/(m²·24h·0.1MPa). This data is crucial for understanding the material's oxygen permeability and its impact on heat patch performance.

Conclusion
Oxygen permeability is vital for optimal heat patch performance. By understanding this property, manufacturers can adjust product design to achieve desired heat delivery. The C106H system provides a reliable method for assessing oxygen permeability, aiding in the development of high-quality heat patches.

Industry Implications
As demand for functional packaging grows, testing methods like those offered by Labthink are essential for comprehensive evaluation and quality control. Collaboration with industry companies is encouraged to enhance packaging quality.

Assessing Heat Patch Inner Packaging Oxygen Permeability-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Assessing Heat Patch Inner Packaging Oxygen Permeability Heat patch is a product designed to provide heat and warmth, often used for personal comfort or therapeutic purposes. It typically comes in a paste or patch form and can be applied directly to the skin. The effectiveness of heat patches is significantly influenced by the oxygen permeability of their inner packaging materials. Oxygen plays a vital role in the exothermic reaction within the patch, and its rate of transmission can directly impact the patch's temperature and duration of heat delivery. This study explores the oxygen permeability of a heat patch inner packaging material using the differential pressure method. The differential pressure method is a widely used technique to measure gas permeability. It involves creating a pressure difference across the material and measuring the rate at which gas diffuses through it. This method is particularly suitable for materials with relatively high oxygen permeability, such as those used in heat patch inner packaging. Labthink C106H Gas Permeability Test System is a specialized instrument designed for measuring gas permeability. It operates based on the differential pressure principle and is 1
