Sterilization Packaging Materials
Recommended Material / Structure
Medical paper-plastic pouches, nonwoven sterilization wraps, SMS wrapping fabric, dialysis paper/PE composite film. Select materials according to EO, steam, or plasma sterilization.
Requirements
Material Performance Requirements
Microbial barrier, sterilant penetration, tear resistance, pack integrity, low linting, and seal stability; packaging integrity must be maintained after sterilization.
Cost Control Requirements
Select basis weight and structure according to device weight and sterilization method; use standard sizes for high-turnover consumables and high-strength SMS or reinforced wraps for heavy instrument sets.
Environmental & Biodegradability Requirements
Choose recyclable mono-material PP wraps or paper-based structures; reduce composite layers and ink usage; assess post-sterilization traceability and disposal routes.
Batch Delivery Requirements
Ensure stable cleanliness, pore size, and strength by batch; use fixed suppliers, fixed resin grades, and online defect detection.
Custom Development Requirements
Customizable color, indicator-ink compatibility, printing, basis weight, size, heat-seal layer, alcohol resistance, antistatic treatment, and double-wrap combinations.
Overseas Export & Certification Requirements
For export, consider ISO 11607, the EN 868 series, sterilization-process validation, and packaging-integrity validation. Compatibility testing is required for different sterilization methods.
Solution Advantages
Good balance between barrier performance and breathability; SMS wrap offers high strength and low linting; supports integrated packaging validation with device manufacturers and sterilization service providers.
Technical Parameters & Selection Recommendations
Recommended basis weight: 35–80 gsm; width: 1.2–3.2 m. Key tests: air permeability, wet/dry strength, tear strength, microbial barrier, seal strength, and sterilization compatibility.
