Overview
The ALLSHENG AS-F03NL Aluminum-Laminated Heat-Sealing Film is a precision-engineered sealing solution designed specifically for high-integrity closure of 96-well deep-well microplates used in clinical diagnostics, biobanking, and high-throughput screening workflows. Constructed from a biaxially oriented polypropylene (PP) substrate metallized with a thin, uniform aluminum layer, the film delivers robust barrier performance against moisture, oxygen, and volatile organic compounds—including ethanol and isopropanol—without compromising thermal stability during automated heat-sealing processes. Its laminated architecture ensures consistent melt behavior across standard laboratory sealing temperatures (typically 120–160 °C), enabling reliable hermetic seals with low delamination risk and zero residual film transfer to plate wells upon peel removal. Unlike generic polymer films, the AS-F03NL is validated for use under controlled environmental conditions per ISO 15195:2018 (laboratory accreditation for medical testing) and supports traceable sample integrity in GLP-compliant storage applications.
Key Features
- Aluminum/PP laminate structure providing >99.9% moisture vapor transmission rate (MVTR) reduction versus uncoated PP films
- Optimized thermal activation profile for compatibility with common benchtop heat sealers (e.g., Thermo Scientific AutoSeal, VWR Sealer Series)
- Clean, residue-free peel performance verified via optical microscopy (≤5 µm particulate shedding per 10 cm² after 100 cycles)
- Chemical resistance validated against 70% v/v ethanol, 75% v/v isopropanol, and 10% sodium hypochlorite solutions for ≥30 min exposure
- Dimensional stability across −80 °C to +60 °C storage conditions; no curling or edge lift observed after 6 months at −20 °C
- Pre-slitted roll format (80 mm width × 300 m length) compatible with semi-automated film dispensers and manual applicators
Sample Compatibility & Compliance
The AS-F03NL film is dimensionally calibrated to ANSI/SBS standard 96-well deep-well plates (e.g., Corning 3679, Eppendorf 0030720016, Thermo Scientific Nunc 260251). It maintains adhesion integrity on both polypropylene and polyethylene deep-well surfaces without requiring surface priming. All production batches undergo incoming material certification per ISO 10993-5 (cytotoxicity) and ISO 10993-10 (irritation/sensitization) testing. The film carries a Declaration of Conformity for RoHS 2015/863/EU and REACH SVHC compliance. While not sterile, it is manufactured in an ISO 8 (Class 100,000) cleanroom environment and packaged in double-bagged, nitrogen-flushed pouches to minimize particulate and hydrocarbon contamination.
Software & Data Management
As a passive consumable, the AS-F03NL does not interface with software systems. However, its lot-numbered packaging (printed with YY/MM/DD batch date and unique serial code) enables full traceability within LIMS environments. Each roll includes a Certificate of Analysis (CoA) listing thickness uniformity (±0.005 mm tolerance), tensile strength (≥45 MPa), and peel adhesion force (1.2–1.8 N/25 mm per ASTM D903). CoA data can be imported into electronic lab notebooks (ELNs) supporting CSV or PDF ingestion, facilitating audit readiness for FDA 21 CFR Part 11–governed workflows where seal integrity documentation is required.
Applications
- Long-term cryogenic storage of DNA/RNA extracts, plasma, and cell lysates in 96-well deep-well plates
- Sealing plates prior to centrifugation (up to 3,000 × g) and freeze-thaw cycling (≥10 cycles)
- Barrier protection during ambient transport of infectious samples under WHO IATA Packing Instruction 650
- Pre-analytical stabilization of volatile metabolites in LC-MS workflows requiring headspace isolation
- QC/QA archiving of reference standards in clinical chemistry laboratories accredited to ISO 15189
FAQ
Is the AS-F03NL film autoclavable?
No. This film is not rated for steam sterilization; its aluminum layer may oxidize and delaminate under saturated steam conditions (>121 °C, 15 psi). For sterile applications, pre-sterilized plates should be sealed post-autoclaving using this film.
Can it be used with PCR plates?
It is not recommended for thermal cycling applications. The aluminum layer reflects infrared energy unevenly, potentially causing inconsistent denaturation profiles and well-to-well temperature variance during PCR ramping.
What is the shelf life under ambient storage?
When stored unopened in original packaging at 15–25 °C and ≤60% RH, the film retains specification compliance for 36 months from manufacture date, as confirmed by accelerated aging studies per ISO 11607-1.
Does it comply with USP for plastic packaging systems?
While not classified as a primary packaging system per USP , its Al/PP composition meets extractables profiling requirements outlined in USP when tested per Method 1 (aqueous extraction at 50 °C for 24 h). Full extractables report available upon request.
