Start the tensile tester and pull until the seal separates completely.
The internal splitting of the adhesive layer itself.

Because flexible films often buckle or curl during testing, ASTM F88 defines three specific ways to support the specimen to ensure consistent results:
Must comply with ASTM E4 precision standards.
Slice samples perpendicular to the seal line into 25.4 mm (1.00 in.) wide strips. Start the tensile tester and pull until the
In conclusion, ASTM F88 is a critical standard for ensuring the safety and quality of food products. By specifying requirements for sealers used in food contact applications, the standard helps to prevent contamination, ensure food safety, and promote quality. Manufacturers, suppliers, and regulatory agencies must work together to ensure compliance with the standard and protect public health.
ASTM F88 is recognized worldwide and serves as a foundational pillar for broader international packaging standards.
