Packaging manufacturer Chesapeake reports that it is developing speciality barrier coatings that offer moisture vapour, flavour and grease proof properties that aim to provide improved performance and environmentally considerate options for a range of packaging formats.
Improved grease barriers are being demanded especially for dried pet-foods which often have oil content in excess of 10%, and traditionally, a substantial layer of plastic has been applied to cartonboard.
Chesapeake’s technique involves applying a special grease-resistant coating to the reverse of a range of cartonboard types. The technique is said to allow the application of coatings that are not typically applied at the board mill during production.
Carol Hammond, Head of R&D at Chesapeake, said, ” We have focused on more environmentally considerate options such as water-based or organically derived coatings to deliver the same benefits. The results are very encouraging and we already have an improved coating for packs that require a flavour barrier. We are close to offering a more environmentally considerate grease-proof barrier as well.”
In a joint project with a Scandinavian paper company, whose name Chesapeake would not reveal, Chesapeake has developed a naturally formed coating that has been applied to paper with additional heat sealing properties and is being tested for various food-packaging applications.
