The 300 ml clear pharmaceutical bottle with a black anodized aluminium cap forms its own category both visually and functionally: the thick-walled clear glass displays the colour of the contents beautifully, while the matte-black metal cap delivers an elegant, modern, more premium contrast. The anodized surface resists scratching and abrasion, and the aluminium retains all of its advantages: airtight, leak-proof, chemically inert. This 40-piece pack is intended for small businesses and makers who want to package a premium-looking, private-label liquid preparation.
What is included in the 40-piece pack
The pack contains 40 clear (water-clear) pharmaceutical bottles and 40 black anodized aluminium caps. Each bottle has a nominal capacity of 300 ml, a height of approximately 200 mm, a diameter of 70 mm, and an empty weight of around 280 g per piece. The total gross weight of the pack is approximately 12.3 kg. The neck has a standard threaded design and the cap seals tightly with an internal sealing liner.
Characteristics of clear pharmaceutical glass
Clear apothecary glass is thicker-walled than ordinary cosmetic bottles, so it is more stable and durable for long-term use. As glass, it is chemically completely neutral: it does not react with the contents and does not leach plasticisers. Transparency makes the colour and clarity of the contents continuously visible, which is particularly striking in liquid cosmetic series. Light-sensitive preparations should be stored in a dark location.
Details of the black anodized aluminium cap
The anodized aluminium cap brings both aesthetic and functional advantages. During anodizing, a thin, resilient coating is added to the surface of the metal, protecting it from scratching, fading, and abrasion. The matte-black colour is deep, saturated, and long-lasting — it does not fade under normal storage. The cap is threaded with a screw closure and an internal sealing liner, providing an airtight, leak-proof seal. Aluminium is chemically inert, does not rust, and adds no off-flavour or odour.
Areas of use
- Premium-looking private-label liquid cosmetics — serum, essence, toner.
- Elegant packaging for tinctures and alcoholic botanical extracts.
- Storing hydrosols, floral water, and herbal decoctions in larger volumes.
- Homemade syrups and honey-botanical preparations in giftable packaging.
- Refined dispensing of liquid household cleaners and concentrates.
Cleaning and recycling
Before first use, rinsing the bottles with warm water and a neutral dish soap followed by thorough drying is recommended. For odour or oily residue, clean 70% ethanol is an effective solvent. The anodized cap surface should be cleaned with a soft cloth; coarse sponges or abrasive cleaners should be avoided, as they can damage the coating over time. A dishwasher is also not recommended. Collected separately, the aluminium cap and the glass are both recyclable.
