8. Professional FAQ: Eye Dropper Bottles Technical FAQ

Q1. What materials are most recommended for sterile eye dropper bottles in ophthalmic applications?

Medical-grade LDPE and HDPE are preferred due to their flexibility, chemical inertness, and transparency. Both comply with USP VI and ISO 10993-5 for cytotoxicity. PET may be chosen for solvent resistance and clarity in certain markets.

Q2. How is volume accuracy validated for plastic eye dropper bottles during quality control?

Random sampling (per ISO 16775) measures dosing deviation from nominal volume. For example, a 10ml model typically achieves ≤0.07ml deviation, ensuring precise medication delivery.

Q3. Which sterilization processes are compatible with these bottles and what standards apply?

Ethylene oxide (EO), steam autoclaving, and high-dose gamma irradiation are the main options. All methods are validated under ISO 11135 and ISO 17665, with effective sterility assurance to SAL 10⁻⁶.

Q4. What closure and nozzle options can be customized for empty eye dropper bottles?

Closures include child-resistant, tamper-evident, and twist-off; nozzles can be long, short, orifice-defined (from 0.8mm to 2.4mm). Custom lengths and color coding available for OEM branding.

Q5. How are eye dropper bottles validated for long-term chemical compatibility?

Accelerated aging and chemical exposure tests (per ISO 22088-3 for plastics) ensure no migration or leachables in contact with typical API (active pharmaceutical ingredient) formulations up to 36 months.

Q6. Are there international regulations for labeling and serialization?

Yes. US DSCSA and EU FMD mandates unique identifier (barcode or QR) for traceability. WK Packing supports GS1/EPCIS serialization and can print Braille for EU markets per EN 15823.

Q7. Can plastic eye dropper bottles be recycled or are there sustainability certifications?

HDPE and LDPE bottles are widely recyclable (code 2 & 4 plastics). WK supports RoHS and REACH-compliant production, and provides eco-certificate for bio-based resin options.
