| Abstract [eng] |
Carton board packaging is a rapidly improving type of packaging. It uses composite structures in which combination of different materials like pulp, coatings, wax, adhesive and other materials with the use of coating, impregnation, and lamination. For food packaging many automated and advanced techniques are carried out for testing transmission rate of grease, oxygen, and moisture. They are few basic methods which determine the resistance of package to grease penetration and many methods give the best quality measure of grease penetration. Cardboard which can be recycled are integrated with packaging and simple process is used for determining grease barrier properties of high substance content product coating and these test results of several different type of coating are presented to describe the effectiveness of these cardboard and which helps in developing the grease barrier properties of these material. Materials for packaging is commonly classified as single materials and multilayer materials with coatings Food packaging of flexible material subjected to pasteurization and sterilization regularly shows delamination phenomena and for many packaging applications, barrier properties play a key role. This contribution is aimed to know the possibility to improve costeffective and analysis of different cardboard material with great barrier properties. |
