Crown Closures Europe has put out three new diameters for its Ideal
brand, expanding the range for which it can be used for packing
foods and beverages.

Ideal was originally produced and available in 40mm and 63mm. Crown is now making the closure available in 51mm, 70mm and 82mm. The closure is a combination of metal and plastic, providing a barrier and a tamper evident seal, while at the same time being easier to open, the company claims. Thierry Lainez, Crown's marketing and communication manager, said the company decide to widen the range to meet a growing demand for the closure. He noted that the 40mm is more suited to the drink market, especially to meet the demand for ready-to-go and single serve products. The 82mm is more suited for big jar and container sizes, for products such asmustard, ready cooked meals and jams. The original 40 mm size is currently being used for products such as infant milk formal formula in the US. The 63 mm size is being used for a large variety of products, such as spreads, jams, fruit juices, peanuts, he said. "More diameters opens many doors for new potential applications,"​ he told FoodProductionDaily.com. The Ideal closure is a hybrid of a plastisol-lined metal disk and a plastic band. The metal disk forms an airtight seal against the container to guard against the entry of oxygen, while the plastic band is designed to make it easy for consumers to open. The plastic band includes a perforated "drop down" section, which breaks before the seal is broken to provide clear tamper evidence. "This eliminates the need for a secondary inner seal,"​ the company stated. "It is applicable for plastic containers and glass, which has proven essential to processors considering a transition."​ The cosure requires less effort when removing the cap because of its two-stage opening mechanism that separates the force required to overcome the friction between the closure threads and the container from that required to release the vacuum in the pack, the company claimes. The company claimed that the closure is suitable for multiple filling processes including hot fill, cold fill, dry seal, pasteurisation and retort.
