Caps and closures developments: Difference between revisions

­

'''It was a Swiss designer named Albert Obrist who in 1970 developed the first plastic top for CSD drinks bottles with the injection-moulded onepiece HDPE cap. Originally intended for use with returnable glass bottles, his idea quickly attracted the interest of the PET bottle industry which increased sharply at the end of the 1970s. The key advantages of the HDPE cap over its aluminium counterpart were considered to be, firstly that damage to the bottle mouth caused by rolling the aluminium caps onto the neck finish could be avoided, and secondly that the HDPE caps were more compatible with the precise geometries of the PET thread. Obrist’s innovations were subsequently incorporated into the Crown Cork and Seal Company’s operations during the mid-1980s.'''

Romeo [[Corvaglia]] reported in issue in 2+3, that the 0.99 g cap for still water was on the market in North America. Issue 9 reported that Coca-Cola China had decided to universally adopt the PCO 1881 by the end of 2009.

In issue 6, the company announces the launch of the DoubleSeal one-piece hot fill closure in the North American market, with reduced wall thicknesses.

Following the K trade fair, PETplanet is publishing a study of the caps and closures markets to describe the state-of-the art technology, starting with issue no. 12/2013 and the developments, strategies and competitive differentiation of the companies involved in the market of suppliers of systems and moulds for the production of caps and closures.

As well as this lightweight trend, the spotlight is increasingly on interest groups with difficulties in opening operations. Brazilian Clever Pack is one example for capping solutions for those who suffer from reduced grip strength, developing reusable building block closures (as reported in 9/14).

Dispensing caps go further: an international project team from Hähl and Teamplast, Incap and [[Sumitomo (SHI) Demag]] developed caps suitable for liquid additives and granules, sellable in combination with a beverage or as an independent refill product (issue 5).

[[Aptar]] launches sports closures for the on the go bottles market, a one-piece flip-top 28 mm PCO 1881 as well as the two-piece bi-injected closure for 29/25 mm neck finish (issue 11+12).

<br>

Continuous growth of aseptically processed beverages and an increase of on-the-go beverage formats are reasons for [[Aptar]] to launch a new sportscap in a wide mouth neck finish. The 38 mm 1-piece closure is described in issue 5.

For issue 10 we fly downunder, visiting Coca-Cola Amatil’s plant opening of their new sports cap production line. Being made entirely of HDPE, it is easier to recycle than the traditional mix of HDPE and PP.

In issue 12 [[Bericap]] highlights UV light barrier screw caps. The product range encompasses 33 mm neck caps and light weight 38 mm neck caps in all colours.
