Key points for selecting a heat sealer for drainage bags

Key Technologies and Selection Considerations for Equipment:

Material Compatibility (Critical): The equipment must perfectly match the film material (e.g., PVC, EVA, TPU, and their composites). Heat sealing temperature must be precise; too low a temperature will cause leakage, while too high a temperature will cause the film to become brittle or burn through.

Sealing Quality: The sealing line must be uniform, strong, leak-free, and able to withstand a certain amount of tensile force (especially critical at the connection between the catheter and the bag).

Mold Precision and Flexibility: The mold design determines the final structure of the product. For producing different models of drainage bags, the ease of mold replacement must be considered.

Production Speed ​​and Automation: Select manual (small batch, multi-variety), semi-automatic, or fully automatic production lines based on capacity requirements.

Compliance: The equipment should be easy to clean, non-contaminating, and meet the requirements of Good Manufacturing Practices (GMP) for Medical Devices. Process parameters should be recordable and traceable.

Brand and After-Sales Service: Established equipment suppliers can provide stable equipment, process support, and timely maintenance.

The drainage bag heat sealing machine is a specialized, high-precision piece of equipment in the production of medical plastic soft bags. Through precise temperature and pressure control, it reliably combines flexible films and functional components to mass-produce safe, sterile, and leak-proof drainage bags. Its core technology lies in the "composite heat sealing of multi-layer flexible materials," a process fundamentally different from the negative pressure heat sealing machines used for rigid bottles.
