4. Graphene Oxide-Based Barrier Coatings for Enhanced Food Packaging
TETRA LAVAL HOLDINGS & FINANCE SA, 2024
A method to produce barrier-coated packaging materials using reduced graphene oxide that provides good gas barrier properties without using aluminum foil. The method involves coating a substrate with a layer of reduced graphene oxide prepared by mixing graphene oxide dispersion, nanocellulose dispersion, and a reducing agent. The mixed aqueous composition is dried to form a thin layer of well-dispersed reduced graphene oxide flakes on the substrate. This provides a barrier coating for gas permeation like oxygen, without needing organic solvents or high temperatures to disperse the reduced graphene oxide. The barrier coating can then be laminated with other materials to make packaging for long-term storage of liquid foods.

11. Humidity-Responsive Nanocellulose Container for Enhanced Food Preservation
BEIJING BOE TECHNOLOGY DEVELOPMENT CO LTD, BOE TECHNOLOGY GROUP CO LTD, 2023
A container for food preservation that adjusts air permeability based on humidity to prevent spoilage without drying out. The container is made of interlaced oxidized nanocellulose layers that expand differently when wet. The oxidized nanocellulose types have varying degrees of expansion after absorbing moisture due to differing carboxyl group contents. This provides dense packing in dry conditions for moisture retention, but gaps expand when humid to allow air exchange. The container prevents excess moisture buildup while preventing dryness.
12. Sustainable Biodegradable Multi-Layer Packaging for Food Products
HUHTAMAKI MOLDED FIBER TECH B V, HUHTAMAKI MOLDED FIBER TECHNOLOGY BV, 2023

The layers include an inner cover layer, intermediate layers, a functional layer, and an outer cover layer. This provides barrier properties like oxygen and grease resistance. The packaging can be manufactured by co-extruding the layers onto a food contact surface of a molded fiber product. The biodegradable layers are fused and crosslinked to the molded fiber for strength and barrier properties. This allows a compostable and sustainable packaging that can replace conventional plastic packaging.

The insulation coating can be applied to one side of the paper, or between layers in corrugated boxes. It allows food to be insulated in the packaging without adding plastic or aluminum foil.
19. Enhanced Humidity-Resistant Barrier Layers for Packaging Using Interpolymer Complex Formation
BILLERUDKORSNAS AB, 2022
Enhanced barrier layer for packaging materials like food, beverage and pharmaceutical packages that provides effective gas barrier properties at high humidity levels. The barrier layer is made by coating a substrate like paper with a polyvinyl alcohol (PVOH) solution containing a small amount of an interpolymer complex forming agent (IPCFA). The IPCFA forms hydrogen bonds with the PVOH to enhance barrier properties. The IPCFA is a water-soluble polymer with functional groups that bond to PVOH's hydroxyl groups. The IPCFA proportion in the coating is 0.5-7.0% (w/w) PVOH. This provides a barrier layer with low oxygen permeability below 14 ml/m2/day/atm when measured at 80% RH. The barrier layer can also optionally contain nanofillers
20. Innovative Microwave Susceptor Food Packaging Using Metal Nanoparticles
FOLIA WATER INC, 2021
Food packaging with integrated microwave susceptor layers that enable faster cooking times and better browning and crisping effects. The susceptor layers are made by directly adding metal nanoparticles to the packaging material, like paper or molded structures, instead of using separate susceptor films. The metal nanoparticles absorb microwaves and convert them to heat, enhancing cooking performance. The nanoparticles are small enough to not impede moisture flow, preventing soggy food. This allows the packaging to be recycled or composted, unlike laminated susceptor films.
