Seeking moisture barrier for paper substrate - Flexible PackagingWe have been working on paper base structures as a potential option for our flexible food packaging to help with our sustainability goals of having 100% RCB compliance for our packages 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. Paper helps us with the end of life issues and can be recyclable, biodegradable and compostable. Maintaining packaging performance such as shelf stability, oxygen and moisture barrier are a must on this project. Oxygen barrier is not a problem with current technologies available but achieving the very high moisture barrier required for packaging dry foods has been a challenge. We understand that new technologies will be needed to achieve the high moisture barrier requirements (< 0.3 g/m2/day under Tropical conditions). Also, it is important to maintain this barrier under forming conditions in the VFFS process of bag-making. We are looking for novel solutions that can be added to the paper, if possible, as a high functional coating applied through flexographic or rotogravure process and/or a skin layer with high functionality that can anchor metal (metallization). The functional layer/coating must be compliant with paper recycling process and biodegradable/compostable.

Seeking 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.

Seeking novel proposals to incorporate pea protein concentrate into low pH beveragesHumans have cultivated and eaten peas (Pisum sativum) for millennia. Modern consumers are looking to the seed as a promising protein source – it is rich in proteins which can be isolated to make pea protein concentrates (PPC). While PPC are available in many forms and products, little or no research has been done to understand its behavior in low pH solution or model systems. As a result, food producers have encountered difficulties incorporating PPC into acidic products, such as fruit juices. The goal of this project is to identify pea protein concentrates that are suitable for usage in low pH systems or to find technologies capable of processing PPC so that they may be used in low pH environments.

Seeking novel bottle and/or bottle closure sanitation methods that reduce or eliminate the use of chemicals and/or water in the sanitation processPepsiCo is seeking novel bottle and/or bottle closure sanitation methods that reduce or eliminate the use of chemicals and/or water in the sanitation process. It is very important to sanitize packaging containing beverages intended for human consumption. Failure to adequately sanitize bottles and bottle closures to remove bacteria, viruses, molds, yeasts, and spores may have serious consequences with respect to product quality and safety, potentially leading to negative customer reactions or even product recall. Peracetic acid (PAA) is a commonly employed and highly effective sanitizer, particularly when used in conjunction with hydrogen peroxide. However, PAA sanitation processes involve a significant amount of water throughout the process including dilution, water rinsing of packaging post-treatment and chemical disposal. Globally, trillions of gallons of beverages are bottled each year. While preserved carbonated soft drinks (CSDs) are the traditional leader in market share, other drinks such as bottled water, juices, non-preserved CSDs, and ready-to-drink teas and coffees are gaining in share. New inventions are needed to ensure that these drinks remain safe, while reducing unnecessary chemical and/or water consumption during production. Proposed solutions should achieve the following objectives: •Reduce or eliminate the amount of water used in bottle and/or bottle closure sanitation processes; and/or •Reduce or eliminate the use of chemicals in bottle and/or bottle closure sanitation processes.
