FAQ for Whirl-Pak Stand-Up Bag (PE, 532 mL, 115 × 230 mm) NASCO B01365:
1/ What material is the bag made of?
The bag is constructed from a high-strength polyethylene blend that offers exceptional clarity and tear resistance, suitable for sampling and food-contact applications.
2/ What are the bag’s dimensions, capacity, and film thickness?
When flat, the bag measures 115 × 230 mm (4.5 × 9 in W × L), holds approximately 532 mL (18 oz), and uses a 3.0 mil (0.076 mm) film.
3/ How does the stand-up feature work?
A gusseted (folded) bottom unfolds as the bag fills, creating a flat base so it stands upright without racks or holders.
4/ How is the bag closed and reopened?
A sterile, aseptic-design Tyvek pull tab system keeps hands clear of the sample. Simply fold the top over or twist the metal-reinforced tab to seal, then reverse to reopen - closure can be repeated as needed.
5/ How can I label the bag?
A white, paper-like write-on strip handles pens, markers, or pencils with minimal smearing, ensuring clear sample identification.
6/ Is the bag sterile, and what is its shelf life?
Bags are sterilized post-manufacture via ethylene oxide (+1 Sterilization), certified RNase-, DNase-, pyrogen-, and BHP-free. Shelf life is five years from sterilization date when stored sealed at room temperature.
7/ What regulatory approvals and quality standards apply?
The bag is FDA-approved for food contact and produced under an ISO 9001 - certified quality management system.
8/ What temperature ranges can it withstand?
Safe use spans -320 °F (-196 °C) for liquid-nitrogen freezing up to 180°F (82°C) for hot samples - handle carefully when frozen to avoid brittleness.
9/ Can I autoclave the bag?
No. These bags are not autoclavable; sterilization occurs only via ethylene oxide processes.
10/ How is it packaged and what purchase options exist?
Standard packaging is 500 bags per box. For higher throughput, you can order cases comprising six boxes (3000 bags total).
11/ What advantages does a stand-up bag offer over traditional bottles?
- Lower cost per sample and reduced shipping risk (no breakage)
- Compact storage footprint
- Two-handed operation for easier pouring, mixing, and handling
- Leak-proof continuous perimeter seal
- Compatibility with solids, semi-solids, and liquids
12/ What sample types and industries is it suited for?
