The 30 ml format combined with an aluminium cap is one of the most reliable cosmetic packaging units: durable, airtight seal, fashionable pink appearance, and a quantity (3–4 months of regular use) that is ideal for a women's cosmetic range. This pack of 330 is designed for small-business operators who think consciously in terms of series.
What is included in the 330-piece pack
The pack contains 330 pink, tinted, semi-transparent glass bottles, each with a nominal fill capacity of 30 ml, plus 330 matching aluminium caps. Bottle height is 85 mm, diameter is 35 mm, and the neck has a standard GL18 thread. Total package weight is approximately 18.15 kg gross, with each empty bottle plus aluminium cap weighing about 50 g.
Pink glass and light attenuation
The pink colour is a semi-transparent painted layer applied to the outer surface of the glass. The interior of the bottle remains neutral and chemically inert and can come into direct contact with essential oils, hydrosols, and cosmetic raw materials. The tinted layer provides moderate light attenuation along with a fashionable appearance that speaks to a female audience. The liquid level is faintly visible through the semi-transparent colour, making it easy to check the remaining content during use.
Aluminium cap details
The aluminium cap is chemically inert and corrosion-resistant: it does not react with essential oils or cosmetic raw materials, does not allow odours to permeate, and contains no BPA, phthalates, or other plasticisers. The airtight seal prevents evaporation of volatile components and oxidation by air — this is particularly important for sensitive anti-aging actives (vitamin C, retinol, vitamin A), which oxidise rapidly on exposure to air. The liner inside the cap ensures a durable, leak-proof seal.
Areas of use
- Anti-aging facial serum, vitamin C serum, retinol-based night oil
- Rose-scented perfume bases and floral fragrance compositions
- Consistently packaged women's cosmetic ranges
- Long-term storage of sensitive active-ingredient cosmetics
- Independent cosmetic brand by an artisan small-business operator
Cleaning and recycling
The glass can be washed with warm water and mild soap; for stubborn fragrance residue, rinse with a few millilitres of isopropyl alcohol. Avoid the dishwasher, as high temperatures and aggressive detergents can fade the semi-transparent painted layer. The aluminium cap can also be washed separately and is recyclable; the glass goes into normal glass collection. The liner inside the cap should be cleaned carefully with alcohol or warm soapy water.
