Abstract
Some embodiments of the invention generally relate to a moisture barrier coating that is biodegradable and compostable. Some embodiments also relate to a coating that is dual ovenable. Such coatings may be used to increase moisture resistance and provide non-stick or release characteristics when applied to biodegradable and compostable disposable food packaging and food service items. In some embodiments, a plasticizer, an amide wax and optionally a rosin are added to a cellulose-ester-based coating to increase moisture resistance. In other embodiments, a biodegradable polymer, an amide wax, optionally a plasticizer, and optionally a rosin are added to a cellulose-ester-based coating to drastically increase moisture resistance. In still other embodiments, phospholipids or medium-chain triglycerides or increased levels of amide wax may be added to the either of the embodiments above to provide enhanced release characteristics.
