Mastering Burst or Creep Testing Introduction: Why Burst or Creep Testing Matters in Flexible Packaging Flexible packaging plays a pivotal role in safeguarding products throughout the supply chain, especially in the food, pharmaceutical, and medical industries. To ensure these packages remain secure and uncontaminated, burst or creep testing is essential. These tests verify the structural integrity and seal strength of packaging under stress, simulating real-world conditions. Compliance with standards like ASTM F1140 ensures that manufacturers meet regulatory expectations while guaranteeing product quality. In this article, we’ll walk through the principles, procedures, and instrumentation—like Cell Instruments’ LSST-01 Leak and Seal Strength Tester—that make these tests reliable and repeatable. Understanding the Burst […]

Flexible Packaging Burst Testing – ASTM F1140 Packaging Burst Test: Essential Testing for Flexible Package Integrity In today’s high-performance packaging industry, the packaging burst test is a vital method for ensuring the structural reliability of flexible packaging materials. From food and pharmaceutical products to medical devices and industrial supplies, package failure can lead to product contamination, spoilage, or costly recalls. The burst test evaluates how much internal pressure a package can withstand before rupture, providing key data on seal and material strength. In this article, we explore how this test works, its connection with burst testing of package seal, and how burst seal strength testing supports quality control processes. https://www.youtube.com/watch?v=rqBmLjJHPlU […]

Bubble Test Packaging- ASTM D3078 Bubble test packaging is a widely accepted technique for evaluating the leak resistance of flexible packaging, especially in industries where product integrity and shelf life are critical. Commonly used in food, pharmaceuticals, medical devices, and consumer goods, this method offers a simple yet effective way to visually detect packaging failures. With packaging standards becoming more stringent, understanding how the leak testing procedure works—especially as defined in ASTM D3078—can help quality assurance teams strengthen their packaging validation processes. Leak Testing Procedure and ASTM D3078 Guidelines The leak testing procedure outlined in ASTM D3078 is officially titled Standard Test Method for Determination of Leaks in Flexible Packaging […]
