Medical dialysis base paper

Bofeng New Materials' medical-grade dialysis paper base serves as the core substrate for manufacturing terminally sterilized medical device packaging bags (dialysis bags). With outstanding breathability, 100% microbial barrier capability, and superior physical strength, this product delivers a critical sterile barrier system for medical devices, ensuring sterility and safety throughout the product's shelf life.

Product Features

• Exceptional Microbial Barrier Properties
  • Delivers outstanding breathability while providing 100% effective barrier against microbial intrusion (including bacteria and fungi), maintaining sterility of packaged contents during transport and storage. Fully complies with ISO 11607 requirements for sterile barrier systems.
• Superior Vapor Permeability
  • Features a uniform, dense pore structure that provides an efficient, rapid penetration pathway for sterilant media like ethylene oxide (EO) and steam, ensuring thorough sterilization.
  • Simultaneously allows residual sterilant gases to rapidly diffuse and evaporate post-sterilization, preventing contamination of the devices.
• Exceptional Physical Strength
  • High internal bonding strength, tensile strength, and burst resistance ensure packaging integrity during high-speed bag forming, filling, transportation, and drop tests, preventing tears or damage.
• Outstanding Cleanliness and Low Particle Shedding
  • Manufactured in a clean environment with strict control over dust and fiber shedding, preventing particulate contamination of precision medical devices.
• Excellent Coating and Laminating Compatibility
  • Features a smooth surface with exceptional laminating strength to medical-grade films (e.g., PE, PP, PETG), preventing delamination and enabling processing into various final sterilized packaging forms.
• Compliance and Biocompatibility
  • Manufactured from pure virgin wood pulp, free of fluorescent whitening agents and toxic substances, meeting biocompatibility requirements.
  • The system complies with relevant international and national standards, supporting global market access for medical devices.
