High-frequency welding's core feature: Technological innovation reshapes medicine bag sealing standards

I. Core Features: Technological Innovation Reshaping Sealing Standards

1. Molecular-Level Uniform Heating, Precise Temperature Control

High-frequency welding uses a high-frequency electric field to excite the internal molecular polarization and frictional heat generation of the material, achieving uniform fusion from the inside out. Compared to traditional heat sealing that relies on external high-temperature conduction, high-frequency welding can precisely control the temperature, avoiding localized overheating that could lead to material carbonization or degradation. This is especially suitable for packaging temperature-sensitive liquids such as traditional Chinese medicine and biological agents, ensuring the stability of drug efficacy.

2. Seamless Structure, Excellent Biocompatibility

High-frequency welding forms a seamless fusion structure, with no glue residue or mechanical indentations, completely eliminating the risk of liquid contamination. The process requires no chemical flux, avoiding the residue of heavy metals and other harmful substances, meeting the stringent biocompatibility standards of the medical industry. It can be directly used in the production of medicine bags for sensitive populations such as newborns and postoperative patients.

3. High Efficiency and Automation, Strong Flexible Production Capability

High-frequency welding equipment can be integrated into fully automated production lines, achieving full automation from raw material transportation and heat sealing welding to finished product inspection. With its rapid mold-change system, the equipment can quickly switch between different specifications of medicine bags, supporting "make-to-order" production and significantly improving production line flexibility to meet the "small batch, multi-variety" production needs of traditional Chinese medicine.

4. Wide Material Compatibility, Environmentally Friendly

High-frequency welding supports heat sealing of various medical plastics such as PVC, PE, and TPU, allowing for the production of different products such as urine bags, bile bags, chest drainage bags, and biodegradable fluid bags without equipment changes. Simultaneously, this technology employs a zero-solvent welding process, reducing VOC emissions and significantly lowering energy consumption compared to traditional processes, aligning with the ESG development requirements of the medical industry.

II. Industry Impact: Technology-Driven Leap in Quality and Efficiency

High-frequency welding technology is driving the transformation of medicine bag production towards "high quality, high efficiency, and greening":

1. Quality Improvement: Significantly enhanced sealing of medicine bags, with a near-zero leakage rate, ensuring patient medication safety.

2. Efficiency Innovation: Fully automated production and flexible switching capabilities shorten the new product launch cycle and improve the company's market responsiveness.

3. Green Transformation: Zero solvent and low energy consumption characteristics reduce carbon emissions, helping the medical industry achieve carbon neutrality goals.
