Plastic screw cap 25 mm Detal-met Z25

Detal-met Z25 is a 25 mm plastic screw cap designed to seal bottles and containers with a matching neck diameter. The cap provides a threaded closure suitable for a range of products including liquids, powders and granular materials. Its simple design supports manual application and automated capping on production lines, offering a consistent seal for packaging, storage and transport.

Advantages

The plastic screw cap delivers a reliable mechanical seal through a standardized thread profile and close fit to compatible necks. Made from injection-molded plastic, the cap is lightweight, corrosion-resistant and insensitive to typical storage environments. Its smooth exterior and uniform dimensions simplify handling, sorting and automated dispensing in filling operations. The cap is compatible with common filling speeds and can be applied by hand or by capper heads on small- to medium-scale production equipment.

Suitable for

• Sealing bottles containing water-based and non-aggressive liquid formulations
• Packaging dry powders, granules and small solid products
• Small-batch and pilot production lines with 25 mm neck fittings
• Storage and short- to medium-distance transport of consumer and industrial goods

Key specifications

• Nominal outer diameter: 25 mm
• Material: injection-molded plastic (polypropylene or similar thermoplastic)
• Closure type: screw/threaded cap
• Application: manual and machine capping compatibility
• Surface finish: smooth exterior for labeling and handling

How to use

Align the cap with the container neck and rotate clockwise until secure, ensuring the thread engages evenly to achieve the intended seal. For machine application, position caps in the cap feeder and verify correct orientation before capping. Do not overtighten by excessive force; apply sufficient torque to prevent leakage while avoiding deformation of the cap or container neck. Inspect caps and container threads for damage prior to use to maintain sealing performance.

Usage recommendations

Store caps in a dry, cool area away from direct sunlight and strong solvents. Select the cap material and sealing configuration appropriate for the stored product; avoid use with strong solvents or aggressive chemicals unless chemical compatibility is confirmed. For transport involving vigorous movement, verify torque settings and consider additional sealing measures such as induction liners or tamper-evident bands if required by the application.
