PepsiCo posted this Technology CallSeeking moisture barrier for bio-based filmsWe have been working on bio-based/biodegradable flexible films for food packaging to help achieve our sustainability goals of having 100% RCB compliance for our packages as well as 20% reduction in GHG by 2030. While flexible package is a very sustainable option from a material use point of view, the multi-layer multi-material structures are not conducive for recycling and mostly end up in the landfill or as litter. While the biodegradable films help us with the end of life issues by designing for managed waste infrastructures like composting and anaerobic digestion, it cannot be at the expense of performance compromises such as reduced shelf stability. Oxygen barrier is not a problem with these films but achieving the very high moisture barrier required for packaging dry foods (< 0.3 g/m2/day under tropical conditions of 38C/90% RH) has been a challenge. We understand that metallization will be needed to achieve the high moisture barrier requirements, but even with metallization we have not been able to reach this barrier with bio-based films. Also, it is important to maintain this barrier under forming conditions in the VFFS process of bag-making. We are looking for novel resins that can be co-extruded with our core resins to form a skin layer with high functionality that can anchor metal to film or highly functional coatings which would serve the same purpose. Inherently high barrier coatings that can be applied as primer coating or top coating over metal could also be a solution.
Hempel Group posted this Technology CallSeeking partners for development of Photovoltaic paint.We are seeking partners that can contribute to the development of a Photovoltaic coating. A partner should be able to contribute within at least one of the following areas: Photovoltaic coating: A coating that has photovoltaic properties and that allows the extraction of the resulting electrons. The coating might contain perovskite particles or other photocatalytic particles. The binder should be able to disperse the photocatalytic particles and should allow the extraction of the generated electricity while providing good film forming properties. The coating could be water based, solvent based or solvent-free. Current collection: Suitable materials for current collection from the photovoltaic coating. Solution on the position of the electrodes relative to the photovoltaic coating as well as the geometry of the electrodes is of interest. Important criteria's for selection of the proper material includes • The catalytic durability of the material. • The photovoltaic paint as well as the current collectors should be easy to apply on site • The durability when exposed to the environment. • The chosen technology should not contain substances of concern and is a candidate for passing REACH and other equivalent regulations.
