Which nanocellulose can be used for coating OPP food packaging film?

In the coating of OPP food packaging film, the following types of nanocellulose can be used:

1. Nanocellulose (CNF) : Cellulose nanofibers are extracted from natural cellulose, with good mechanical strength and biocompatibility, and can improve the strength and barrier properties of the membrane.

2. Nanocellulose hydrogel : This form of nanocellulose can be used as a coating, providing good flexibility and moisture retention ability, suitable for fresh-preserving packaging.

3. Modified nanocellulose : Chemically or physically modified cellulose nanofibers can impart additional properties to the membrane, such as antibacterial, ultraviolet or anti-fog functions.

4. Nanocellulose composite materials : Combining nanocellulose with other materials (such as polymers, metal oxides, etc.) can enhance the barrier properties and mechanical properties of the film.

Using cellulose nanofibers as coating materials can not only improve the functionality of food packaging film, but also increase its biodegradability, meeting the needs of sustainable development.
