When it comes to providing testing for flexible barrier material, such as medical packaging seals or medical pouches, adhering to the ASTM F88 testing standard is essential. The ASTM F88 Peel Test System from CSC Force Measurement provides complete compatibility with this standard using the most common 90 degree supported and unsupported method. Support for the 180 degree method can also be added to this functional testing system at a nominal cost. It involves adding an alignment plate to support the test specimen.
Importance of Seal Strength
The quantitive measure for use in process validation, process control, and capability is known as seal strength. This is relevant for package integrity and the opening force required by the user, but also for the benefit of measuring the ability of the packaging processor to provide continually consistent seals. This is a necessary package requirement for many different types of packaging, but it is extremely important when used for medical packaging seals.
According to the ASTM F88 testing standard, the testing method used for flexible barrier material should cover the measurement of the strength of the seals. The test may be conducted on seals between both a rigid material and a flexible material. Seals tested according to this standard can come from either a laboratory or a commercial source. A peel test system will measure the force that is required to separate a test strip of flexible barrier material that contains the seal and identifies the model of failure.
What to Expect
When a customer purchases the ASTM F88 Peel Test System from CSC Force Measurement, they can expect to receive a cost-effective solution. Additional options may be added, depending on their unique needs, in an a la carte fashion. Some of those options include average peel force and graphing the results. Not all of the requirements of the ATSM F88 standard are mandatory, so these functions are available as add-on functions. This helps businesses to cut costs on the initial investment of the equipment.
The standard peel test system includes a Mark-10 ESM303 Motorized Test Stand, a Mark-10 Series 5 Force Gauge with 20 lbF capacity, and Mark-10 G1008 grips and jaws. We also include all necessary interface cables and adapters for the functional testing system. An overload protection option and an auto return option also come standard. The system comes with ISO 17025 accredited calibration and certificates.
Common Types of Peel Tests
The purpose of this type of testing is to determine the adhesive strength of a material or to test the strength of the adhesive bond between two different materials. The most common types of peel tests or tensile testing used for flexible barrier material include the 90 degree peel, and the 180 degree peel. Each test adheres to the ASTM F88 testing standard but provides unique testing methods and results.
- 90 Degree Peel – This particular test is used to determine the adhesive strength between a flexible and rigid substrate. The rigid substrate or plate lies horizontally and uses a grip to place the end of the flexible substrate or tape sticking up in a perpendicular fashion. The rest of the material is bonded to the plate to form an “L” or 90 degree shape.
- 180 Degree Peel – While similar to the 90 degree peel test, the bonded area that is between the flexible and rigid substrates is placed vertically between the peel test grips. The free end of the plate is gripped by the bottom, and the free end of the tape is gripped by the top, forming a very tight “U” shape, which results in a 180 degree peel technique.
Designed to Perform
The ASTM F88 Peel Test System from CSC Force Measurement was designed to meet the needs of customers who require a peel test system for flexible barrier material. Right out of the box, the standard functional testing system will provide all of the proper speed control, peak force readings, and average force readings required by the ASTM F88 testing standard.
In addition, the system includes software to create a basic Excel spreadsheet to export raw data results. Manual vice action grips in a 1.25-inch width are included for ease of use. However, pneumatic grips are also available to be used with the peel test system, as well as a software interface that provides graphing and reporting capabilities. Everything you need comes with this comprehensive peel test system from CSC Force Measurement.
