ASTM F2559 Sterilizable Peel Pouch Package Testing

ASTM F2559 package testing defines flexible peel pouches meant to be sterilized for the containment of medical devices. As an ISTA and ISO 17025 certified lab, we realize the importance of sterilization testing. Meeting the ASTM F2559 requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone provides comprehensive reports shortly after completion of the testing. When packages do not meet the requirements, we assist with finding solutions. Lastly, Keystone takes a consultative approach throughout the entire test program. Our proven consultative process helps avoid product launch delays.

Summary of ASTM F2559 Sterilizable Peel Pouch Information

For this test, the peel pouches are categorized as chevron, header, and corner peel. The pouches are generally made through heat sealing or cohesive cold sealing. Either way, the seal is meat to be peeled open. The pouch can be porous, nonporous, or a combination but must meet the printing requirements outlined in the standard.

Scope of ASTM F2559 Package Testing

ASTM F2559 gives guidelines or writing a specification. The specification is required to address materials, method of manufacture, physical properties, performance requirements, dimensioning, appearance, and printing. Peel pouches are used universally by the medical device industry and it is imperative that regardless of the manufacturer or material, they maintain their sterility during physical handling.

Pouch requirements are divided into “initial pouch and material qualification” and “routine production and receipt requirements”. In most cases, initial pouch testing is only needed prior to the first order to ensure that the product is up to standards. Routine production requirements must be adhered to for every order to ensure that the customer is receiving the proper product.

Significance of ASTM F2559 Sterilizable Peel Pouch Testing

The supplier and purchaser of the pouches will agree upon specifications and requirements in the following areas:

Classification

  • The pouch will be categorized by style: chevron, corner peel, or header bag

Materials and Manufacture

  • Non-toxic, microbial barrier, appropriate physical barrier, and compatible with sterilization process
  • Pouches should be manufactured in a formal quality system
  • Materials should demonstrate compliance with requirements during initial package qualification
  • Validate manufacture process to ensure it is reproducible with consistent results that adhere to all standards

Physical Properties

  • Fabricated in such a way that the seal will withstand sterilization, distribution, storage, and handling
  • Specified seal strength- measured by tensile test method

Performance Requirements

  • Peeled pouch seal characteristics and requirements
  • The seal should be opened to conduct a performance peel assessment that will evaluate a pouch’s ability to withstand different environments

Dimensions and Tolerance

  • Dimension requirements should be decided based on product fit and function

Workmanship, Finish, and Appearance

  • Loose foreign matter limits (inside and outside the pouch)
  • Wrinkle free to eliminate voids in the seal
  • No scratches or scuffing on film
  • Smooth, cleanly cut pouch edges

Printing

  • Determine if the inks should meet standards such as water resistant etc.
  • Ink color
  • Includes all correct legible print
  • No smears or smudges
  • Specify placement and location of print

Sampling

  • Testing should be done on an appropriate number of samples to be representative of actual production

Packaging and Package Marking

  • Packaging should include multiple wraps and be packed in a shipping case that meets weight requirements
  • Staples and high box stacking are not recommended
  • Cases should be strapped to a pallet for secure shipping

Supplementary Requirements

  • Traceability of materials
  • Determine how changes will be handled in the future.
