Frequently Asked Questions (FAQs)

What size bottles are these dropper plugs compatible with?
These dropper plugs are specifically designed to fit 10ml and 15ml white LDPE dropper bottles with a 13mm neck finish. We recommend confirming your bottle’s neck size before ordering to ensure compatibility.

What does “natural” mean in terms of colour?
Natural refers to the uncoloured, slightly translucent off-white appearance of the raw HDPE material — no dyes or pigments have been added. This gives the plug a clean, neutral look that pairs well with white dropper bottle assemblies.

What is HDPE and why is it used?
HDPE (High-Density Polyethylene) is a robust, chemically resistant plastic widely used in pharmaceutical and cosmetic packaging. It offers excellent resistance to a broad range of liquids and oils, making it a reliable and safe choice for dropper applications.

Are these plugs compatible with essential oils and other concentrated liquids?
Yes. HDPE has strong resistance to many essential oils, tinctures, and cosmetic formulations. However, if you are working with particularly aggressive solvents or high-concentration actives, we recommend conducting a compatibility test before full-scale use.

Do these plugs come with a dropper or pipette insert?
No, the dropper plug is sold separately. It is designed to work as part of a complete dropper bottle assembly alongside your chosen cap and bottle.

How is the dropper plug inserted into the bottle?
The plug is press-fitted into the neck of the bottle. It should be inserted firmly and evenly to ensure a secure seal. No tools are required for standard insertion.

Can the dropper plug be reused once removed?
While the plug can be removed and reinserted, repeated removal may affect the integrity of the seal over time. For best results and hygiene, especially in commercial or retail applications, single-use is recommended.

Are these plugs sold individually or in bulk?
These plugs are available in bulk quantities, making them ideal for manufacturers, product formulators, and packaging businesses. Please refer to the product listing for available pack sizes and pricing.

Are these plugs recyclable?
Yes, HDPE is one of the most widely recyclable plastics. Check with your local recycling facility for guidance on how to dispose of or recycle HDPE packaging components in your area.
