Meltblown Fabric 25G for Protective and medical mask

25 g/m² is a widely used basis weight for the filtration layer in protective and medical masks. At this weight, the meltblown web provides a fine fibre network that supports particle filtration while maintaining breathability. It is also a basis that many mask production lines are set up to process, which simplifies specification alignment across product programs.

The dielectric addition supports stable web behaviour and static control during converting. On high-speed mask assembly lines, uncontrolled static can cause web misalignment, dust attraction, and feeding issues. The dielectric component helps reduce these effects, supporting consistent web tracking and yield.

The 170-250 mm range aligns with the web widths used in many mask production lines. Ordering a roll width that closely matches the line format reduces the need for slitting and lowers edge trim waste. This supports tighter material yield planning and reduces the number of processing steps between incoming material and finished mask.

EN13795 provides a performance reference for materials used in controlled medical environments, while ISO13485 addresses quality management system requirements. Together they give buyers documented references that can be included in tender submissions, supplier qualification files, and audit documentation, reducing the need for additional verification by the purchasing organization.

Sterilization compatibility determines which post-assembly treatment a finished mask can pass through. A substrate suitable for ETO, Beta, and X-Ray treatment allows one material to serve multiple mask programs without requalification. This reduces the number of materials a buyer needs to source and simplifies inventory and changeover management.
