Cap Matching

This bottle uses an 18/410 neck finish. Compatible CRC caps are available separately, but the bottle and cap must be confirmed as a matched combination before bulk production.

Cap fit alone does not confirm sealing performance. The cap, liner, sealing torque, filling process and liquid formula should be tested together under the buyer’s actual storage and transportation conditions.

Formula Compatibility Testing

Fragrance oils, essential oil blends, alcohol-containing liquids and solvent-based formulas may perform differently in PET packaging. We do not guarantee that this bottle is suitable for every formula.

Buyers should test their actual liquid with the intended bottle, cap and liner before confirming a bulk order. Testing should include haze, whitening, swelling, deformation, leakage and liner compatibility.

For preliminary evaluation, you can order the PET Diffuser Refill Bottle Sample Pack before mass production.

Customization Options

• Custom bottle color
• Logo printing
• Custom adhesive labels
• Shrink labels
• Matched CRC caps and liners
• Custom carton or retail packaging

Custom colors, logo decoration and special packaging normally require a higher MOQ. Please provide the required quantity, artwork, bottle color, cap requirement and delivery destination when requesting a quotation.
