ASTM F88 (Seal Strength Test)

Testing Standard: ASTM F88: Test Method for Seal Strength of Flexible Barrier Materials

Standard Number: ASTM F88

Standard Title: Test Method for Seal Strength of Flexible Barrier Materials

Overview:

ASTM F88 is a test method that covers the measurement of the strength of seals in flexible barrier materials. Can also be conducted on seals between a flexible material and a rigid material. This test method measures the force required to separate a seal and determines the mode of specimen failure. Purple Diamond Testing offers ASTM F88 Testing as part of our packaging compliance and validation services.

Rationale:

ASTM F88 – Test Method for Seal Strength of Flexible Barrier Materials. It’s intended to be used as a quantitative measurement for process validation, capability, and process control. Seal strength data is not only relevant to opening force and package integrity, but consistency of the seals. This test method is commonly utilized for validation methods for porous and non-porous heat-sealed medical pouches. Although the maximum seal force is important information, the average seal force and the mode specimen failure data could be quite useful.

Why the Seal Strength Test?:

• Evaluates the performance of seals in medical packaging as well as in consumer goods packaging.
• Serves as a quantitative measurement for process validations and process control.
• Use ASTM D882 for tensile strength on thin plastic sheeting.
• Use ISO 11607-1 for specifications on pass/fail criteria.

ACHIEVING ISO 17025

• Achieving ISO 17025 Accreditation is the pinnacle in third-party laboratory testing accreditation. It confirms that the facility has management, quality, and technical systems in place to ensure accurate and reliable analyses.

Related Standards:

• ASTM D882 – Test Method for Tensile Properties of Thin Plastic Sheeting
• ASTM D4332 – Practice for Conditioning Containers, Packages, or Packaging Components for Testing
• ISO 11607-1 – Packaging for Terminally Sterilized Medical Devices – Part 1: Requirements for Materials, Sterile Barrier Systems and Packaging Systems
