Different Types of Packaging Closures

Closures, lids and caps are the guardians of packaged goods, shielding them from damage, leakage and loss. Here are the main families and what each one is for.

Different types of packaging closures caps and flanges

Metal Drum Closures and Flanges

For 200L or 55-gallon steel drums, G2 and G3/4 metal closures and flanges are the standard. They are sealed with EPDM, BUNA or PE gaskets and provide a reliable seal against leaks and contamination during transport and storage.

Plastic Drum Closures

Plastic closures are a lightweight and cost-effective way to seal plastic drums or barrels in both industrial and consumer markets. They are typically made from high-density polyethylene or polypropylene, come in various sizes, and can be supplied in different colours or customised.

Jerry Can Screw Caps

Screw caps are used across jerry cans for food and beverage, pharmaceuticals and home care products. The threaded design screws onto the neck of the container and forms a tight seal to prevent leakage and contamination.

Pull Out Spout Closures

Pull out spout closures allow convenient and controlled dispensing. A retractable spout extends for pouring and retracts for storage, which minimises mess and waste. For tin cans, plastic containers and plastic pails they are the practical answer where the contents are poured by hand.

Choosing Between Them

The container material decides the family: metal drums take metal closures, plastic barrels take plastic closures. After that the choice is functional, between a plain seal, a tamper-evident seal, a vented closure and a dispensing closure.
