Custom Glass Cosmetic Bottles: Materials and Closure Options
Custom glass bottles for cosmetics come in a few standard glass types and a wide range of closures. Understanding the basic choices helps you brief a supplier clearly.
Glass type: clear glass shows the product color; frosted glass softens the look and hides minor contents variation; amber glass protects light-sensitive formulas; cobalt blue and green glass give a distinctive brand appearance. The same bottle shape can be made in different glass colors depending on the factory's mold availability.
Closures: a screw cap with an aluminum or plastic shell is the standard option; a pump dispenses lotions and liquids; a dropper dispenses serums and oils drop by drop; a crimp cap is common for perfume and spray products. The neck finish of the bottle must match the closure you choose — this is a compatibility point your supplier checks.
Decoration: screen printing, UV printing, frosting and spray coating can carry your logo and brand color. Suitability depends on the glass surface and the decoration method.
When sourcing, confirm four things together: glass type and color, capacity, neck finish and closure, and decoration method. These four decisions determine most of the cost and lead time.
