Packaging of more sustainable drinks thanks to the recycled PET flakes
Husky Injection Molding Systems commitment to sustainability comes from old, as well as its vocation to offer its customers innovative solutions to make their activities more sustainable. Many packaging for beverage manufacturers want to improve in this chapter without loss of quality and performance of their products. Husky carries out a continuous work of r & d that generates tangible improvements in the form of differentiated solutions that extend the possibilities for cost reduction and lower the ecological footprint of beverage containers.
An example of this is recycled scales HyPET (HyPET RF) system of Husky, designed specifically for the bottle to bottle recycling, through the manufacture of preforms with high percentages of recycled PET food quality scales. The HyPET system allows significantly increase the amount of PET that is recycled bottle to bottle and aid to PET containers are more sustainable.
Maintenance of the quality and benefits
In the past, the challenge was to increase the amount of recycled in beverage packaging scales at the same time maintaining the benefits and the high quality of the bottles. The recycled scales raised a further complication due to the differences between the properties and behavior of the scales and the pellets. The Husky HyPET RF System solves the problem with a unit of injection specifically designed for the recycled scales. His ability to mix produces a more homogeneous material, continuous filtering reduces the presence of black spots and their shorter thermal process minimizes thermal degradation. The HyPET RF system is based on the platform of high performance High Performance Package (HPP) of Husky and offers the same times of cycle, performance, reproducibility of injections and weight distribution.
Increase in flexibility
HyPET RF technology is geared to the specific problems of the production of PET bottles using recycled PET flakes, and allow manufacturers who do not yet use this material put it in their products.
In regards to those who already use them, this technology can solve some problems of production and quality, leading to an increase in the percentage of recycled scales. Unlike the strategies that process high content scales in conventional systems, HyPET RF helps to keep the shorter cycle times and better levels of quality with percentages of recycled scales varying from 0 to 100%.
Reduction of waste and costs
In comparison with the recycled pellets of food category, the process of production of flakes for food applications does not imply merger or extrusion, which equates to a better cost and a smaller ecological footprint. However, the scales traditionally have the disadvantage that they are not suitable for melt filters. This problem is eliminated through the filter of mass cast in continuous joined the HyPET RF System. In this way, manufacturers can use a material cheaper and smaller footprint without sacrifice of quality or the performance of the bottles. On the other hand, the new extruder of the HyPET RF system is specifically designed to avoid the usual step of increasing of extrusion screw, which means additional energy savings.
