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.”
