Roll on Bottle

The Roll on bottle (rolling ball bottle) is a type of packaging container commonly used for applying liquid products locally. Its core design and functional features are as follows:

Material types
Plastic material: Mostly made of PP (polypropylene), suitable for products with large capacity (such as 30ml, 50ml, 70ml, 90ml) and requiring repeated filling, it has leak-proof and durability features.
Glass material: Includes transparent glass and amber glass, with smaller capacity (such as 4ml, 10ml, 14ml), commonly used for high-end products like perfumes and essential oils that need to be stored in a dark environment. Application scenario
Cosmetics and skin care products: Precise application of essential oils, perfumes, deodorants (including antiperspirant gel) and nail polish.
Portable design: Mini-sized (3ml - 12ml) suitable for travel or sample packaging. Some are paired with bamboo bottle caps to emphasize environmental friendliness.
Functional features
Ball-bearing design: Controls liquid flow through top ball bearings to avoid waste.
Re-fillable: Some models allow users to refill contents themselves, extending the lifespan of the packaging.
