UCP ahead of the game with closure safety standards

26 July 2012


UCP has relaunched its range of closures for aggressive products packed in tinplate containers with full accreditation to ISO 8317:2003 (requirements and test methods for reclosable child-resistant packaging).

Part of the Global Closure Systems group, UK-based United Closures and Plastics says that getting the improved accreditation at this point was essential, as the ISO 8317:2003 standard is expected to be implemented before the final date for the EU’s REACH regulations in 2015.

REACH, the regulation for Registration, Evaluation, Authorisation and Restriction of Chemicals, came into force on 1 June 2007, and governs the protection of human health and the environment from the risks that can be posed by chemicals and their production.

“UCP has tested its 25mm and 40mm Clic-Loc closures on a wide range of oblong tinplate containers,” the company says.

“After considerable efforts to find a suitable thermoplastic with acceptable chemical resistance, UCP selected a grade of acetyl to replace the thermoset material, which whilst very effective, was prone to breakage during the capping process.”

While the pharmaceutical industry has adopted ISO 8317:2003, the household sector currently still operates the previous standard ISO 28317:1993. Both standards require a minimum of 90% of adults to correctly open and reclose packs within a prescribed time period, with the same child resistance performance.

The essential difference between the two standards is that ISO 28317:1993 tests adults in the age range 18-65, whereas ISO 8317:2003 recognises the need to cater for an ageing population by testing adults in the age range 50-70 only – making the standard significantly more demanding to achieve.
