Rounded Clear Plastic Bottle, Silver Aluminium Cap, 100 ml

A clear PET bottle with a volume of 100 ml and an aluminium screw cap makes ready-to-use packaging for liquid and thin cosmetic products that are dispensed by pouring. The clear plastic shows both the colour and the level of the contents, and the material is lightweight and does not shatter when dropped, so the bottle is suitable for travel, for the bathroom and for customer samples. The silver aluminium cap with a 24/410 thread closes the bottle without a dispensing element and sets it apart visually from bottles with ordinary plastic closures.

The set is declared suitable for contact with cosmetic products. It is not intended for food packaging.

What it is suitable for

• Body and massage oils – thin oils pour smoothly from the 24/410 neck, and the clear wall shows the colour of the oil and how much of it is left.
• Hydrosols and toners – water-based products applied with a cotton pad or into the palm. If you want to spray the contents, choose a sprayer with the same thread instead of the cap.
• Make-up removers and micellar waters – simply tilt the bottle, as the cap only closes it.
• Shower oils and liquid soaps in smaller packs – the 100 ml volume is suitable for trial batches or gift sets.
• Diluting and transferring raw materials in the workshop – as technical-grade packaging, it can also be used for a measured water phase, glycerine or solutions without a dispenser.

Filling and volume

The nominal volume of 100 ml is the amount the bottle is designed for in normal filling. The total brimful volume is larger and you will find it in the parameters. The difference is the headspace below the neck, which leaves room for the cap and for the expansion of the contents when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim.

The aluminium cap has an EPE liner inside, which sits on the neck and seals the joint. When carrying the bottle, tighten the cap by hand without force. Aluminium deforms under excessive force and the liner then no longer seals evenly.

Good to know

PET withstands ordinary water-based and oil-based formulations. However, a high proportion of essential oils, concentrated fragrance compositions or solvents may soften or cloud the plastic over time. For such contents, we recommend testing how the packaging behaves on a single bottle before you fill the whole batch.

Clear plastic does not protect the contents from light. Products with unstable active ingredients, unfiltered vegetable oils or light-sensitive tinctures keep better in amber or blue glass. A clear bottle is suitable where visible contents are an advantage and the product is used up steadily.

You will find other closures with the same neck type, as well as ready-made combinations of the bottle with a pump or a sprayer, in the Handymade range. If you are making your own combination, we recommend checking the tightness and dispensing with your specific formulation.
