Physical Testing Properties for Food

A wide range of materials, including aluminum and other metals and non-metallic materials such as paper and plastic, is used for packaging. According to their application, these materials must meet certain tensile, compression, and bending strength requirements, and if an adhesive is used, adhesive strength requirements. In the examples below, adhesive strength results for liquid-filled pouch, wheat noodle and dry snack package specimens are shown. In both instances, the adhesives meet the requirements of being strong enough to protect the contents, but weak enough so that the contents can easily be accessed by consumers.
