Bottles made of polyethylene terephthalate (PET) are increasingly used in the bottling of oxygen-sensitive products with high barrier requirements. This trend is especially evident on the fruit juice shelves of supermarkets. Due to the large amount of time and effort needed for the experimental determination of a bottle’s O2 barrier properties, a numerical approach was investigated with the aim of faster bottle development.

A few months after Interpack, the beverage specialists among the packaging experts will be meeting again in fall from September 11 to 15, 2017, at Drinktec in Munich, Germany. Trade show innovations are not to be expected everywhere here, but are definitely to be found where plastics processing and use are concerned.

Refining the Details 

The Italian machine manufacturer Sacmi has developed a new solution for filling beverages into PET bottles. The core of the system is the so called CPB Link, the first dynamic cap and preform buffer that is capable of synchronizing processes upstream and downstream of the bottling line. The result is door-to-door converting and bottling, from pellet to secondary packaging.

Comprehensive resource efficiency means far more than the preservation of natural resources. It also includes the productivity factors of material, machine and labor. The plastics industry has made a great contribution to resource efficiency, but often finds itself on the defensive. Yet a knowledge of the various relationships involved provides enough material to go on the offensive with arguments illustrating the benefits of plastics technology.

Resource Efficiency with  Plastics Technology 

Rotation, shear, heat and pressure – this much is clear: These are the factors required to compound plastics on twin screw extruders. From a scientific point of view, however, the question remained until recently as to which mechanisms exist during incipient fusion along with the energy input into the melt resulting. Scientists from the plastics division at Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt, Germany, have been successful in gaining an insight into these processes by using new types of measuring techniques.

Sacmi to Provide ‘Green Transition’ Solutions

New tethered standards, lightweighting and recycling will be Sacmi’s focal points at Interpack 2023.

Sacmi provides solutions for every stage of rigid packaging production, from cap to preform, from stretch-blow molding to complete bottling lines. On the cap manufacturing front, Sacmi has already implemented the EU Directive that requires adoption of the new tethered standard from 2024 onwards. With a complete range of caps and profitable methods – such as post-process slitting and integrated quality control – Sacmi is ready to respond to market requirements and guide the transition.

In recent years, few industries have focused as sharply on sustainability as packaging has. As the data clearly shows, container and cap weights have fallen by 50% or more since 2010. The latest developments in this area include the 26/22 mm (with the 25/22 variant) and the new lightened 29/25 mm necks, a set of standards on which the Sacmi Laboratory has developed ready-to-market solutions that can cut neck+cap plastic consumption by 30% or more. The new ‘tethered-friendly’ caps for GME 30.40 necks and the 26/22 caps for water combine increased height with considerable raw material savings.

From a 3Rs (reduce, reuse, recycle) perspective, the PET supply chain is the one best suited to a circular economy approach, from resin recycling to finished containers for food use. That’s why Sacmi has long since ensured its preform injection presses are able to process up to 50% PET in recycled flake form, a figure that can rise to 75% with the latest developments being introduced. This offers customers an adequate technological response on markets where the ecological transition is a must, at a time when the tools to achieve it – and the existence of a complete recycling chain – are still in the making.
