More than just a position for product information and branding messages, beverage labels has evolved to provide more benefits for manufacturers. By Raffaele Pace, labelling product manager, Sidel
Chinese bottled water manufacturer Nongfu Spring previously had a four-litre family sized bottle which was only available in high density polyethylene (HDPE). Wanting to make the switch from HDPE to PET for this, they turned to PET production equipment and services provider Sidel for a solution. By Sidel
SIPA is working on large PET dispenser bottles that are fit for purpose in transport and use, and which collapse on themselves as neatly as possible when they empty.
To achieve this, the company has taken to running simulations of collapsing sequences using Finite Element Method analysis to determine the buckling mechanism that would best suit the client’s requirement. The shapes of the bottle, ribs and base were also analysed to determine the most efficient design.
Fully collapsible containers that require no external mechanical forces to deflate are currently in industrial production, which would make the job of collecting them for recycling or simply putting them in a recycling bin much easier than before.
Sidel, in conjunction with Roquette, a bio refining group, has introduced new chemicals that use renewable agricultural materials in place of fossil-based ones.
The new bio-based polyesters could potentially be used in PET packaging development, leading to increased transparency, UV resistance and a heightened resistance to high temperatures.
Leading names within the beverage industry, such as Coca-Cola, PepsiCo, Danone and Nestlé are already exploring the possibilities of bottles being made from fully renewable resources, and are said to already been assessing the most promising options to incorporate these bottles into their production line.
The demand for liquid dairy products has been growing, especially in developing markets. The conversion towards plastic bottles can create a more convenient consumer experience without compromising on product integrity. By Max Duclot, zone senior aseptic specialist & senior dairy officer, Sidel
