Film packaging materials play a critical role in maintaining product integrity across industries like food, pharmaceuticals, and consumer goods. One of the most essential evaluations in ensuring film performance is the plastic tensile strength test. This test not only quantifies the film’s mechanical resilience but also lays the foundation for further assessments such as heat seal strength under ASTM F2029 and ASTM D882. In this guide, we explore how to carry out these tests accurately, their relevance to packaging reliability, and how Cell Instruments supports quality assurance with professional-grade equipment. Understanding the Plastic Tensile Strength Test in Packaging Films The plastic tensile strength test measures a material’s resistance to tension …

In packaging, printing, and industrial applications, the strength of paper is a critical performance indicator. Among the most accurate ways to assess this property is through short span compression testing for paper, a standardized method for measuring the compressive strength over a very short span. This test is essential for quality control in paperboard production, carton manufacturing, and corrugated board applications where buckling resistance matters. Understanding the Test SCT and ISO 9895 Compliance The short span compression test (SCT) is guided by international standard ISO 9895, which defines how paper and board samples should be prepared, clamped, and tested. The SCT method is designed to simulate real-world compressive forces, such …
