White Plastic Bottle, 24/410, Black Mat Plastic Cap, 150 ml

A white plastic bottle with a volume of 150 ml and a matte black screw cap is a ready-made packaging and closure combination for liquid and semi-liquid cosmetic products. The bottle is made of PET, it is lightweight, and a fall onto a hard floor will not harm it. The white opaque material hides the contents and limits the access of light, which you will appreciate with formulations containing light-sensitive ingredients, or with products whose colour or cloudiness should not be visible at first glance.

The volume suits body lotions, shampoos, shower gels, toners, facial waters, body and massage oils, and make-up removers, that is, everything that is dispensed by pouring into the palm or onto a cotton pad. The set is declared suitable for contact with cosmetics. The certificate for direct food contact applies to the bottle alone; the set as a whole is intended for cosmetics.

How to work with the set

The cap with a 24/410 neck finish sits directly on the bottle neck, so no further parts need to be bought for the packaging. The closure has no dispensing opening; the contents are poured out after unscrewing. It therefore works best with thin to medium-thick liquids. Thick creams and butters will come out of the narrow neck with difficulty, and a jar or a bottle with a pump is better suited to them.

The matte black finish of the cap contrasts in colour with the white bottle, so the packaging looks finished even without a label. If you want to combine the bottle with a different closure, in the Handymade range you will find closures with the same neck type as well as other ready-made combinations. For a custom assembly, we recommend checking the tightness and behaviour of the packaging with your specific formulation.

Nominal and total volume

The nominal volume of 150 ml is the quantity the bottle is intended for in normal filling. The physical volume up to the neck is larger. The difference between the two values is a reserve for the cap thread and for the expansion of the contents with changes in temperature, for example in a bathroom or during transport. The bottle is therefore filled up to the nominal volume. If you filled it up to the neck, the cap would sit in the liquid and the contents could spill out when closing.

Preparation, filling and reuse

• Before the first filling – wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol, and let them dry completely. Residual water would dilute the product and worsen its microbiological stability.
• Filling temperature – PET is not intended for hot contents. Let emulsions and gels cool to room temperature before filling them.
• Reuse – after washing and disinfection, the packaging can be filled again. With every new filling, check that the cap thread still seats firmly.
• Recycling – the bottle belongs in PET waste and the cap is made of polypropylene; separate them before disposal.
