ROPP caps are commonly found in the wine and spirits industries, where the need for tamper evidence, product integrity, and a premium presentation is particularly high. However, they lend themselves to other industries that want to combine tamper-evident features with a corrosion-resistant material. Unlike crown caps or twist-off caps, which are designed for easy opening, these ROPP closures are ideal for more security or re-sealing your bottles.
