PET Diffuser Refill Bottle Sample Pack – 20ml, 120ml & 500ml with CRC Caps, Express Shipping Included

PET Diffuser Refill Bottle Sample Pack

This PET diffuser refill bottle sample pack is designed for fragrance oil, diffuser refill and scent machine refill projects that require packaging compatibility testing before bulk orders.
Because fragrance oils, essential oil blends and solvent-based formulas may react differently with PET packaging, we recommend testing your actual formula before confirming mass production.

The sample pack includes three commonly used refill bottle sizes: 20ml, 120ml and 500ml. Each bottle set includes a clear PET bottle and a matched black child-resistant cap with a heat induction foil liner.
This allows buyers to evaluate bottle clarity, sealing performance, cap liner compatibility and general packaging stability before placing a wholesale order.

What Is Included

Why Compatibility Testing Is Recommended

PET bottles are commonly used for diffuser refill packaging, but the final packaging performance depends on the actual fragrance oil formula.
Some fragrance oils, essential oil blends, alcohol-based formulas, solvent-rich formulas or formulas with certain aroma compounds may affect plastic packaging if they are not tested in advance.

Before placing a bulk order, buyers should test their own liquid with the actual bottle and cap system. This helps reduce the risk of packaging issues after production, filling, storage or transportation.
The purpose of this sample pack is not only to check the bottle appearance, but also to evaluate how the bottle, cap and foil liner perform with your own formula.

• Check whether the bottle becomes hazy, cloudy or white after filling.
• Check whether the bottle swells, softens or deforms during storage.
• Check whether there is leakage after sealing.
• Check whether the cap remains tight and stable.
• Check whether the heat induction foil liner is compatible with your formula.
• Check whether the filled bottle remains acceptable after normal handling and transportation simulation.

Suggested Testing Method

1. Fill the bottle with your actual fragrance oil, diffuser refill or scent machine refill formula.
2. Seal the bottle with the matched black child-resistant cap.
3. Store the filled bottle upright and upside down for 7–14 days.
4. Check the bottle body, neck finish, thread area, cap and foil liner.
5. Observe whether there is haze, whitening, deformation, leakage or liner damage.
6. If possible, extend the test under your normal warehouse, transportation and end-use conditions.

For new formulas, premium fragrance oil products or commercial scent machine refill projects, a longer testing period may be useful.
Buyers may also test under different temperatures, storage positions and handling conditions to better understand the packaging performance before mass production.

Important Compatibility Disclaimer

This sample pack is provided for packaging compatibility evaluation only.
We do not guarantee that PET bottles are suitable for every fragrance oil, essential oil blend, alcohol-based formula or solvent-based formula.
The buyer is responsible for testing and approving the packaging with their own formula before placing a bulk order.

Test results may vary depending on the formula, filling method, storage time, storage temperature, transportation conditions and other handling factors.
Bulk production should only be confirmed after the buyer has completed their own packaging compatibility test and approved the final packaging system.
