Influences of Raw Materials and Concentration on Properties of Natural Cellulose Films

Abstract:

To study the effects of different raw materials and concentration on properties of natural cellulose films, the dissolution of different raw materials and propyl gallate (PG) in N-methylmorpholine-N-oxide (NMMO) by rotary vacuum evaporation machine were operated, and glycerol was used as plasticizer. The results show that the mechanical properties, oxygen barrier, moisture barrier, transparency of the films which used cotton pulp as raw materials are superior to wood pulp and reed pulp. Cellulose concentration increase from 5% to 7%, the elongation, oxygen permeation flux, water vapor permeability, light transmittance decrease by 17.2%, 1.4%, 4.4%, 16.6%, respectively, the tensile strength of cellulose film increases by 103.1%.
