BOTTLE MAKING 22 PETplanet Insider Vol. 24 No. 11/23 www.petpla.net between different and potentially conflicting requirements: aesthetics, functionality and performance on the one hand, and packaging sustainability on the other. From this point of view, Sacmi has implemented projects together with the brand owners, in keeping with the increasing sensitivity of manufacturers to the issue of recycled resins and respect for the environment, whether or not it is enforced by current regulations. One of the most interesting projects implemented for leading global players was the design and development of a lightweight container for highly carbonated CSD that reduced the total weight from 22 to 18.5 g and included 25% of recyclate, successfully achieving this double challenge. Important results were achieved in the production of low-pressure bottoms. A 40% saving on the amount of compressed air was achieved, allowing CSD containers to be blown using a pressure of 15-20 bar, compared to the 25-29 bar required by the traditional method. The various projects Sacmi has been involved as a ‘single partner’ for the supply of both the bottling line (blowing and filling), the IPS machine for preforms and, lastly, the CCM (continuous compression moulding) press for caps, for which Sacmi is known for. In the development of ‘turnkey solutions’ – which are particularly popular in the African market, for example with the recent projects finalised in Kenya, Tanzania, etc. The PET-in-box opportunity Research and development into new solutions from a technological point of view, which are capable of intercepting new market trends is an important part of Sacmi Beverage’s activities. One interesting proposal is the development of PET-in-box, i.e. the replacement of the traditional BIB ‘bag’, which is difficult to recycle, with a PET bottle blown from a super-light preform. Sacmi stated that the advantage is a net saving on material which – taking the standard 5, 8 or 10 litre formats as an example – is more than 50% (from 125-130 g to 69 g). The container can easily be recycled in the traditional PET chain. The application developed does not require the production of special preforms. In fact, the lightest preform already available on the market was used to make a standard 41/48mm neck, with the possibility of improving weight reduction even further depending on the application requested and the availability of ultra-light preforms. www.sacmi.com 5IF SJHIU JOTQFDUJPO TPMVUJPO '03 &"$) #055-& $0/5"*/&3 888 */53"7*4 $0.
