Application of high frequency heat sealing machine in medical industry
I. Core Application Areas
-
Medical Packaging Materials
- Disposable medical supplies packaging: High-frequency sealing of plastic bags for syringes, infusion sets, catheters, etc., to ensure a sterile environment.
- Pharmaceutical packaging: Sealing of aluminum-plastic blister packs (PTP) with precise temperature control via high-frequency heating to avoid thermal degradation of drugs.
-
Medical Protective Equipment
- Protective suits and surgical gowns: Seamless bonding of non-woven fabrics or composite materials through high-frequency welding, enhancing protective performance.
- Masks: High-strength yet flexible welding of ear straps to masks using high-frequency heat sealing.
-
Medical Device Manufacturing
- Infusion bags and blood bags: High-frequency sealing ensures leak-proof bonding of multi-layer plastic films.
- Artificial organ encapsulation: High-frequency welding provides sterile sealing and biocompatibility for packaging artificial heart valves, vascular stents, etc.
- Catheters and connectors: Precision bonding of medical-grade plastics (e.g., PVC, PE) to maintain fluid channel integrity.
-
Rehabilitation and Care Products
- Medical mattresses and anti-decubitus pads: Multi-layer composite material bonding for breathability and support.
- Hot/cold therapy packs: Sealing of non-woven fabrics with gel layers to ensure product durability.
II. Technical Advantages
