Peel Strength Seals Used in Food Packaging Test Equipment

Quality of food upon opening is directly related to the quality of the packaging material and the strength of the seal that locks freshness in. To ensure a quality adhesive seal in food packaging material the seal strength must be determined. To determine seal strength, adhesive seals undergo a peel test; 90 degree peel test, 180 degree peel test, and T peel tests are the most common variations of peel tests. The specific manner in which the peel test is done to determine the sealant properties of your product package is dependent of standards that must be met. These standards might be internally based, industry based, or requirement based. The standard test methods that TestResources suggests for determining the seal strength of food containers are ASTM F88, and ASTM D903. ASTM F88 is a general standard for seal strength of materials used in packaging. This standard is not used with sterile packaging. ASTM D903 is another general standard for determining the adhesive strength of materials. TestResources universal material testing machines are effectively used for determining the peel strength, bonding strength, and sheer properties of adhesives of materials used in food packaging. TestResources test machines meet the requirements specified in many standard test procedures for constant-rate-of-extension and constant-rate-of-load machines. This allows the machines to be programmed to perform many unique testing procedures. Load cells are fitted to specific load applications to ensure the highest resolution of tests.
