Next-Gen Packaging: Edible
and Protein-Based Films
Protein-Based Films
Protein-based films excel in coating and pack-
aging applications due to their strong intermo-
lecular interactions. Their excellent solubility, di-
verse molecular weights, and specific isoelectric
points enable the creation of durable, flexible,
and functional films.
Bioactive Compound Delivery
These films also stand out for their ability to
carry and release bioactive compounds such as
probiotics, prebiotics, and phenolic compounds.
Their unique molecular structure encapsulates
these compounds effectively, promoting intesti-
nal health and boosting immune response. This
