Understanding CSR Wrappers in Sterile Processing

CSR (Central Supply Room) sterilization wrappers are an essential part of infection control in medical and veterinary settings. These non-woven SMS (Spunbond-Meltblown-Spunbond) polypropylene wrappers serve as a sterile barrier system, ensuring medical instruments, trays, and surgical supplies remain uncontaminated until use.

At Proteq Medical, we offer SMS CSR wrappers in three standard weights: 40 gsm, 45 gsm, and 60 gsm. Each weight is designed for specific applications, balancing durability, flexibility, and protection. Depending on sterilization needs, these wrappers can be used in single or double layers. For enhanced efficiency, bonded double-layer CSR wrappers are available as a custom product upon request.

Why Choose SMS CSR Wrappers?

SMS non-woven material is the preferred choice for CSR sterilization wrappers due to its high strength, fluid resistance, and breathability. Compared to traditional materials, SMS wrappers offer:

• Superior bacterial barrier: The meltblown core of SMS material provides an effective microbial barrier while allowing sterilant penetration.

• Tear resistance: The durable structure resists punctures and tears, ensuring the sterility of packed items.

• Low linting: Helps maintain the integrity of surgical instruments and reduces particle contamination.

• Multi-method sterilization compatibility: SMS CSR wrappers are suitable for Steam, Hydrogen Peroxide (H₂O₂), Ethylene Oxide (EO), Formaldehyde (FO), and Gamma sterilization.

• Versatile usage: Ideal for packs, light basin sets, surgical instruments, medical devices, linen packs, and trays.

• Compliance with industry standards: Manufactured in accordance with ISO 11607 and EN 868-2 for effective sterile barrier performance.

Choosing the Right CSR Wrapper Weight

The selection of CSR wrapper weight depends on the weight and type of medical supplies being sterilized:

• 40 gsm: Recommended for lighter trays, small instrument sets, and single-layer wrapping.

• 45 gsm: A versatile option for general sterilization needs, offering a balance between flexibility and strength.

• 60 gsm: Ideal for heavy surgical sets, orthopedic trays, and double-layer wrapping, providing maximum puncture resistance and durability.

For additional protection, double-layer wrapping may be necessary for heavier or high-risk instruments. The inner and outer layers create a sequential barrier against contaminants while allowing efficient aseptic opening.

Bonded Double-Layer CSR Wrappers – Available Upon Request

To streamline the wrapping process, Proteq Medical offers bonded double-layer CSR wrappers as a custom product. These pre-bonded layers eliminate the need for separate wrapping, reducing handling time and improving efficiency in high-volume sterilization settings.

Traceability & Shelf Life

Each CSR wrapper includes LOT, Production Date, and Expiry Date information, ensuring full traceability and quality control. Our SMS CSR wrappers have a shelf life of 5 years, maintaining their integrity for long-term storage.
