ROPP Capper Gaining Popularity Across Industries

ROPP capping machines have been a staple across the wine and spirits industry for many years. The unique caps have also been seen on different food products over the years, such as olive and other similar oils. However, Liquid Packaging Solutions has seen a recent trend of expansion regarding the ROPP capper, with more and more companies outside of the Wine and Spirits Industry moving to the aluminum caps.

This upward trend in popularity for the ROPP capper and the move into more industries may stem from several different sources. For example, ROPP cappers provide tamper evidence when the threads are formed on the bottle. As the capping head descends onto the cap and bottle, the heads create threads on the blanks, which are typically aluminum based. These threads allow consumers to feel safe knowing a product has not been opened or otherwise tampered with prior to purchase.

Another likely reason for the rise in use is simple aesthetics. ROPP cappers offer an alternative to a flat plastic cap that can be seen on a majority of beverages, food products and other items. The new industries moving to ROPP caps may simply be adding the cap to stand out from the competition while also providing tamper evidence. And of course, for most packagers, the decision to use an ROPP cap comes not from a lone source, but from a combination of the above two examples and other benefits or justifications of using this closure type.

ROPP cappers can be manufactured for production both large and small. Automatic ROPP cappers can use multiple heads with an automatic cap delivery system to allow for continuous sealing as bottles move down a power conveyor system. Operators of automatic ROPP cappers will usually only need to ensure bulk caps are available for the machine. These machines are often integrated with automatic rinsers, fillers and labelers to create a completely automatic packaging line.

Semi-automatic ROPP cappers require operator interaction with each bottle sealed. These machines may use a cap chute to allow the operator to move multiple bottles into place for capping. In the alternative, operator may place the cap on the bottle and then move the cap and bottle combination into place to allow the machine to perform its sealing task. Either way the operator will need to interact on a more regular basis when using a semi-automatic version of the capping machine. While speed is limited to the ability of the operator, the semi-automatic capping machine ensures consistent and reliable capping of every bottle.
