The seal cap system for PE drums consists of a plug and a tamper-proof sealing cap, either in red or white. The outstanding feature of the system is that it cannot be opened without breaking the seal cap, as the inner seal ring is firmly incorporated in the ring. The filling product is fully protected against unwanted discharge or contamination. The seal cap is available for a variety of different bung sizes.
The seal cap can be fitted automatically or manually. First, the seal cap is placed on top of the plug; it centres itself automatically due to the position of the snap latches. Light pressure on the positioned seal cap makes the locking ring snap into place behind the snap latches in the plug. The rigid construction ensures the lock remains securely in place once fitted. The plastic tab connectors on the cap and the inner seal ring tear when the cap is opened. The ring is perforated, making it easy to lift off the seal cap. The cap is opened and lifted off in a single movement by pulling on the seal cap ring pull, allowing the plug to be unscrewed and the contents to be removed.
