The cap is manufactured with its thread structure already formed and is designed to match a compatible threaded glass bottle neck.

Different sizes can be considered for narrow-neck bottles, standard glass bottles or wider-mouth containers. Final suitability depends on the complete neck finish rather than the nominal diameter alone.

The available nominal sizes are:

• 18mm
• 28mm
• 38mm
• 63mm
• 89mm

A cap should not be selected only according to the approximate bottle mouth diameter. Please also confirm:

• Complete bottle neck finish
• Thread series and profile
• Bottle neck height
• Required cap height
• Bottle opening diameter
• Sealing surface
• Existing cap sample, if available
• Bottle drawing or physical sample

For example, different 28mm bottles may use different thread series and may require different caps. The actual bottle and cap should be tested together before production.

Available customization may include:

• Custom aluminium cap color
• Top logo printing
• Side logo or product text
• Matte, glossy or metallic appearance, subject to confirmation
• Different liner options
• Custom export carton marks

The correct liner should be selected according to the filled product, bottle sealing surface and storage conditions.

Potential applications depend on the selected size and liner. Please provide the actual product filled in the bottle rather than selecting the cap only by appearance.

For logo customization, please provide an editable AI, EPS or PDF artwork file and a Pantone color number if accurate brand color matching is required.
