Aluminium Bottle, Transparent Plastic Cap, 100 ml

Aluminium bottle with clear cap, 100 ml is a ready-made set: a metal bottle with a 24/410 neck finish and a ribbed plastic cap. Once filled, you only need to close it and it is ready to sell or to pack in your travel bag. Aluminium blocks light from the contents completely, the bottle is lightweight and it does not break when dropped. It is therefore suitable for products that should not be exposed to light and for cosmetics that you carry with you.

Both parts of the set are declared as suitable for contact with cosmetic products. The set is intended for cosmetics, not for food.

What it is suitable for

• Face and body oils – the metal packaging blocks the light that accelerates the oxidation of oils. A volume of 100 ml lasts for several weeks of use.
• Massage and hair oils – an unbreakable bottle withstands the bathroom and a travel bag better than glass.
• Liquid soaps, shampoos and shower gels – with a pump or another closure for the 24/410 neck, it becomes a dispensing bottle. With a screw cap, it serves as a storage or travel bottle.
• Toners and water-based products for travel – the narrow neck allows you to pour even small amounts. Check compatibility with your specific water-based formulation by filling a test bottle.
• Liquid intermediates in production – pre-weighed oils or blends that need to be protected from light and are easy to transport.

Filling and volume

Nominal volume is the volume the packaging is designed for under normal filling. Brimful volume is the physical volume up to the neck and you can find it in the parameters. The difference between them is a reserve for the cap or a pump fitted later and for the expansion of the contents with changes in temperature. Fill to the nominal volume, not to the brim. Otherwise the contents leak out when you close the bottle and the cap does not seal.

Cap and closing

The cap is made of polypropylene with a sealing liner of foamed polyethylene, which sits on the neck and seals the contents. The ribbed sides give a good grip even with oily hands, which you will appreciate with oils. The clear version lets the silver bottle stand out and does not change its appearance.

Closures with the same 24/410 neck type and ready-made bottle + closure combinations are available in the Handymade range. If you combine them yourself, check the seal, the dispensing and how the packaging behaves with your specific formulation.

Good to know

Aluminium packaging does not let light through, so you cannot see through the wall how much of the contents is left. For your own use, it is enough to give the bottle a shake. Metal conducts heat faster than plastic, so the contents follow the ambient temperature. Keep this in mind when filling warm blends and when storing the bottle by a window.

The compatibility of aluminium with water-based, acidic or alkaline contents varies depending on the formulation. Before filling a larger batch, leave a test bottle standing for several weeks and monitor the appearance of the contents, the scent and the condition of the inside of the bottle. For oil-based products and anhydrous blends, aluminium is commonly used packaging.

After washing and disinfection, the bottle can be reused if the inside is not damaged or stained by the previous contents. The sealing liner in the cap gradually loses its elasticity, so check it when you refill. At the end of its life, the aluminium bottle belongs in metal recycling and the plastic cap in plastic recycling.
