ASTM F88

مواد التطبيق

ASTM F88 focuses on determining the seal strength of flexible barrier materials. Common materials include plastics, foils, and laminates used in packaging industries such as food, pharmaceuticals, and medical devices.

عملية الاختبار

  1. تحضير: Cut test specimens from the sealed package, ensuring they are uniform in size.
  2. يثبت: Mount the specimen in the testing device, with each end of the seal gripped by the machine.
  3. الاختبار: Apply a tensile force to the specimen at a constant rate until the seal separates.
  4. قياس: Record the force required to separate the seal.

تفسير نتيجة الاختبار

  • Peak Force: The maximum force recorded before the seal fails, indicating the seal strength.
  • Mode of Failure: Observing how the seal fails (e.g., adhesive failure, cohesive failure, or substrate failure) provides insights into the seal quality.

أهمية الاختبار

  • ضبط الجودة: Ensures the integrity of packaging, preventing contamination or spoilage.
  • امتثال: Helps meet industry standards and regulatory requirements for packaging.
  • Product Safety: Confirms that seals can withstand handling, transportation, and storage conditions.
