Spirits packaging places a premium on shelf presence, tamper evidence, and opening experience. Aluminum ROPP closures are widely used on whisky, gin, rum, and other premium spirits because they provide a clean, integrated tamper band and a resealable thread formed directly onto the bottle neck . The RM100 automatic ROPP capping machine is designed for glass spirits bottles within its bottle and cap ranges, with servo-controlled torque and multi-head configurations for medium-to-high output lines.

Spirits bottles often use tall, heavy glass and premium aluminum closures. The ROPP format gives the brand a closure that looks finished and performs repeatably: the thread is formed onto the glass, the pilfer band tucks under the locking ring, and the consumer can reseal the bottle after opening. For distilleries moving from cork or bar-top stoppers to aluminum closures, the RM100 provides a production-scale capping solution.

Spirits bottles are often heavier than wine or food bottles. The conveyor and bottle support must keep the bottle stable under the capping head. If the bottle tilts or shifts during forming, the thread can be incomplete or the cap can be wrinkled . The RM100’s inline design and adjustable capping head height help maintain alignment, but the conveyor and guide rails should be set for the specific bottle.

For premium spirits, the opening torque is part of the consumer experience. A cap that is too loose feels cheap and may leak; a cap that is too tight can be difficult to open or may break the pilfer band prematurely. Servo-controlled torque allows the operator to tune the forming process to the bottle and cap, and the adjustable capping knives allow height and tightness to be set for each format. First-article testing should include opening torque and pilfer band performance.

The RM100 runs at up to 42 bottles/min. A craft distillery or small-batch producer may need only a 4-head machine. A larger distillery or contract bottler may specify 6 or 10 heads to match a faster filler. The capper should be sized to exceed filler output by a margin, so that capping does not become the bottleneck on the line .

Premium spirits often use decorated or thicker aluminum closures. The cap path and elevator should be configured for the specific cap. The RM100’s SS304 cap path is custom-built to the cap diameter and thickness, and the cap elevator is optional. Handling must avoid scratching or deforming the closure before it reaches the bottle.
