Types of Bottle Capping Machines

We offer a variety of capping machines tailored to suit your production output, container styles, and cap types.

Benchtop Screw Cap Cappers

Perfect for small to medium operations, our benchtop screw cap cappers provide precise torque control and reliable results. These compact cap tightening machines are easy to operate and ideal for startups, R&D, or short runs.

Automatic Inline Screw Cappers

Our auto inline screw cappers are built for continuous, high-volume production. These fully automatic screw cap tightening machines integrate seamlessly into your line, delivering accurate cap torque and efficient throughput.

ROPP & Stevlin Cappers

We supply ROPP cappers for roll-on pilfer-proof aluminium caps — commonly used in the beverage industry — as well as Stevlin capping systems for tamper-evident, premium packaging. Both ensure product safety and shelf appeal.

Trigger Cap Capping Machines

For bottles with spray triggers or pumps, our trigger cap capping machines are purpose-built for accurate placement and consistent tightening. These are essential for personal care, cleaning, and industrial packaging.

Understanding Bottle Capping Machines

Bottle capping machines are critical for sealing containers securely after filling — helping protect your product and preserve its shelf life. They’re the second essential component in an efficient packaging system and are often used alongside filling, labelling, and induction sealing equipment.

How Do Cap Tightening Machines Work?

Depending on the cap type and machine model, cappers work by applying torque in one of several ways:

  • Screw Caps: Pre-threaded caps are tightened with mechanical chucks or spindle wheels

  • ROPP Caps: The cap is formed to the container during application, ensuring tamper-evidence

  • Trigger Caps: Side-grip systems align and press-fit spray and pump tops

Most systems can be adjusted for different cap sizes, container types, and torque settings, offering flexibility and ease of use.

Choosing the Right Capping Machine

When selecting the right screw cap tightening machine, consider:

  • Cap Type & Size: Screw, ROPP, trigger, or Stevlin closures

  • Container Shape: Round bottles, glass jars, plastic containers, etc.

  • Production Output: From manual benchtop lines to fully automatic inline systems

  • Line Integration: Standalone or inline setup with filling and labelling systems

Our team can recommend the ideal machine based on your needs — whether for small artisan runs or high-speed commercial production.
