Grand Puff closures are engineered to standardized GPI neck finishes including 18/400, 20/400, 28/400, 38/400, and 53/400 thread profiles. Selecting matching GPI thread codes ensures a leak-proof seal and smooth torque performance across manual and automatic capping machinery.

Cross-reference jar profiles and cap neck finishes using our Flower Jar Sizing Chart or pop top dimensions via our Pop Top Sizing Chart.

Grand Puff caps with induction foil liners utilize high-frequency electromagnetic sealers to bond a hermetic barrier onto jar rims. Hermetic induction seals prevent oxygen intrusion, stop volatile terpene loss, and provide tamper-evident security for retail distribution.
