Package Integrity Testing

Package Seal Integrity Testing

Package integrity testing is important in determining the shelf life of a product, such as bottle caps, aerosol cans (and valves), trigger pumps, ink cartridges, cosmetic bottles, food sachets and other various types of packaging. Labthink Package integrity testing equipment includes two test methods: vaccum leak and bubble leak.

Seal Strength (Pack Integrity) Testing
Test conditions based on ASTM F88

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

Seal strength is a quantitative measure for use in process validation, process control, and capability. Seal strength is not only relevant to opening force and package integrity, but to measuring the packaging processes' ability to produce consistent seals. Seal strength at some minimum level is a necessary package requirement, and at times it is desirable to limit the strength of the seal to facilitate opening.

Vacuum Leak Testing
Test conditions based on ASTM D3078

ASTM D3078 -- Standard Test Method for Determination of Leaks in Flexible Packaging by Bubble Emission

This method is to submerge the specimen into water within the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen.Observe the bubble emission from the package

Labthink product under this ASTM D3078: MFY-01 Leak Tester

Bubble Leak Testing
Test conditions based on ASTM F2096

ASTM F2096 --Standard Test Method for Detecting Gross Leaks in Medical Packaging by Internal Pressurization (Bubble Test)

The method is first to inflat the sample with air to predetermined pressure, and then submerge the package underwater, and last visually inspecte for a steady stream of air bubbles

Labthink product under this ASTM F2096: LSSD-01 Leak and Seal Strength Tester (cutomizaed).
