Sterile Barrier System Bags by Tailin Biotech

Overview

Tailin Biotech Sterile Barrier System (SBS) Bags are medical-grade packaging solutions engineered to maintain the sterility of reusable and single-use devices throughout sterilization, transportation, and storage. Designed in strict accordance with ISO 11607-1:2019 (Packaging for terminally sterilized medical devices — Part 1: Requirements for materials, sterile barrier systems and packaging systems) and aligned with FDA guidance on sterile barrier integrity, these bags function as integral components of validated sterilization processes—including saturated steam (autoclave) and ethylene oxide (EO) gas sterilization. The system relies on a dual-material construction: a microporous medical-grade crepe paper (imported from EU-certified suppliers) laminated to a transparent, low-extractable polyethylene-based film. This architecture ensures optimal gas permeability during EO cycles while providing robust microbial barrier performance post-sterilization (validated per ISO 11140-1 for EO indicators and ISO 11737-1 for bioburden retention).

Key Features

• Multi-format design options: flat-roll stock, gusseted 3D pouches, self-sealing peelable bags, and custom-cut preformed bags—enabling compatibility with diverse loading configurations and automated packaging lines.
• Transparency-enhanced film layer allows full visual verification of contents, placement, and instrument count prior to sealing—reducing procedural errors and supporting traceability workflows.
• Lead-free, water-based indicator ink printed directly onto the paper layer; exhibits sharp, non-smearing color transition (e.g., from beige to brown) upon exposure to sterilant, meeting ISO 11140-1 Class 1–3 performance criteria.
• Imported medical-grade crepe paper with controlled pore structure (mean pore size <3.0 µm) and validated air permeability (≥100 L/m²·s at 1.2 kPa), facilitating rapid EO diffusion and minimizing residual gas entrapment—critical for cycle efficiency and patient safety.
• Integrated microbial barrier validated per AAMI ST77:2022 and ISO 11140-1; demonstrates ≥6-log reduction against Bacillus atrophaeus spores under worst-case challenge conditions.
• Non-toxic, non-pyrogenic materials compliant with USP Biological Reactivity Tests, Class VI, and ISO 10993-5 cytotoxicity requirements.

Sample Compatibility & Compliance

These SBS bags accommodate a broad range of medical devices—from stainless-steel surgical instruments and fiber-optic endoscopes to powered handpieces and implantable components—without compromising seal integrity or sterility assurance. All configurations undergo routine validation per AAMI TIR30 and ISO 11607-2:2019 for seal strength (≥1.2 N/15 mm per ASTM F88), burst resistance (>150 kPa), and dye penetration testing. Batch-specific documentation includes Certificate of Conformance (CoC), biocompatibility summary reports, and sterilization validation support data. Products are manufactured under a QMS certified to ISO 13485:2016 and registered with China NMPA (Class II Medical Device Registration No. [redacted for privacy]).

Software & Data Management

While the bags themselves are passive components, Tailin Biotech provides digital traceability support through optional QR-code labeling (customizable per customer ERP integration) and batch-level documentation packages compatible with electronic quality management systems (eQMS). Each production lot is assigned a unique identifier linked to raw material certifications, in-process test records (including tensile strength, seal peel force, and microbial challenge logs), and final release reports. Documentation conforms to FDA 21 CFR Part 11 requirements for audit-ready electronic records when delivered via secure portal.

Applications

• Hospital central sterile supply departments (CSSD) for routine autoclaving and EO sterilization cycles.
• Medical device contract manufacturers requiring ISO 13485-compliant packaging for OEM distribution.
• Dental clinics utilizing compact tabletop sterilizers with space-constrained chamber dimensions.
• Research laboratories handling sensitive diagnostic tools requiring documented sterility maintenance over extended shelf life (validated up to 24 months under controlled ambient storage).
• Emergency field deployment kits where rapid visual confirmation and reliable barrier performance are mission-critical.

FAQ

Are these bags suitable for both steam and ethylene oxide sterilization?
Yes—each configuration is validated for use in gravity-displacement and prevacuum steam sterilizers (121°C–134°C, 15–30 min) and low-temperature EO chambers (54°C ± 2°C, 60% RH, 600–1200 mg/L EO concentration).

What evidence supports their microbial barrier claim?
Barrier efficacy is demonstrated through independent third-party testing per ISO 11737-1 (microbial retention) and AAMI ST77 Annex D (bacterial challenge), with results archived in the Design History File (DHF) for regulatory submission.

Can custom printing or labeling be applied?
Yes—Tailin offers flexographic and thermal-transfer printing services for lot numbers, barcodes, sterilization indicators, and facility-specific identifiers—all compliant with ISO 15223-1 symbols and GHS labeling conventions.

Do you provide technical support for sterilization validation?
Tailin’s Application Engineering team supplies protocol templates, material compatibility matrices, and joint validation assistance for IQ/OQ/PQ phases—subject to confidentiality agreement and project scope alignment.
