CAPS & CLOSURES 18 PET planet Insider Vol. 21 No. 01+02/20 www.petpla.net Sacmi proposal with the option of the tethered feature Sustainable trends in caps Ten years ago, the beverage industries adopted the light weigh PCO1881 neck finish, in order to reduce package weight and reduce plastic consumption.The efforts for further light weighting and better sustainability never stopped and times are ready for a new lighter neck finish, which might replace PCO1881. The Cetie worked on a new 26/22mm neck finish, which is named GME30.37. It is currently used for medium and high carbonated soft drinks (CSD) across Europe. (Fig.1) On top of being manufacturer of continuous compression moulding machines and related moulds with about 2000 units installed worldwide, Sacmi’s core lies in the R&D lab, which so far developed more than 1,000 caps design. Sacmi’s proposal for the GME30.37 neck weighs 1.65 g in the version for CSD. The neck/cap finish combination allows saving up to 1.8 g per package compared to current PCO1881, and it is already on the market, produced by a leading global player. Considering both the weight and energy savings, Sacmi claims that it is another big step forward for the environment. On the same sustainability topic, the Sacmi 26/22mm cap can feature a tethered function (Fig. 2), with a sepa- ration force higher than 25 Newton, in order to already comply with the EU Directive 2019/904. The directive, in fact, states that beverage containers with a capacity of up to three liters that have caps and lids made of plas- tic may be placed on the market only if the caps and lids remain attached to the containers during the products’ intended use stage, starting from 2024. Therefore, new investments can be done without the need to worry for future legal requirements. www.sacmi.com Fig.1: PCO1810 - 5.06g PCO1881 - 3.81g GME30.37 - 2.4g Fig.2: Sacmi 26/22mm cap can feature a tethered function with a separation force higher than 25 Newton.
