Abstract: The carboxymethyl cellulose (CMC) made from modified beet fiber and the polyvinyl alcohol (PVA) were used to prepare compound packaging films in the different proportions. The results indicated that under the conditions of CMC amount 30%,ammonia water 0.75%,concentration of film-forming solution 5%,and glutaraldehyde amount 6%,the prepared com-pound film has better oxygen and water barrier perfor mance.
