Nowadays, non-degradable plastic packaging materials have caused serious
environmental pollution，posing a threat to human health and development. Renewable
eco-friendly nanocellulose hybrid (NCs-hybrid) composites as an ideal alternative to
petroleum-based plastic food packaging have been extensively reported in recent years.
NCs-hybrids include metal, metal oxides, organic frameworks (MOFs), plants, and
active compounds. However, no review systematically summarizes the preparation,
processing, and multi-functional applications of NCs-hybrid composites. In this review,
the design and hybridization of various NCs-hybrids, the processing of multi-scale
nanocomposites, and their key properties in food packaging applications were
systematically explored for the first time. Moreover, the synergistic effects of various
NCs-hybrids on several properties of composites, including mechanical, thermal, UV
shielding, waterproofing, barrier, antimicrobial, antioxidant, biodegradation and
sensing were reviewed in detailed. Then, the problems and advances in research on
renewable NCs-hybrid composites are suggested for biodegradable food packaging
applications. Finally, a future packaging material is proposed by using NCs-hybrids as
nanofillers and endowing them with various properties, which are denoted as
“PACKAGE” and characterized by “Property, Application, Cellulose, Keen,
Antipollution, Green, Easy.”
