The packaging of food should follow the principle of convenience and portability. The tensile strength of kraft paper makes it very suitable for the needs of packaging. In order to prevent the bag from being broken when the consumer carries the food, the packaging materials should have good tensile strength. Beverage packaging requires that the materials have certain moisture resistance and deformation resistance to prevent deformation and damage of water absorption.
For frozen food packaging, the use of high-strength materials as packaging is also the key to consider, this material must be able to withstand the low temperature freezing and high temperature melting of the expansion and contraction of heat, to prevent deformation, distortion, wrinkling and excessive moisture absorption can not hold food. From these aspects, the primary color kraft paper is even more suitable than SBS paper.
