Manufacturers are increasingly embracing materials that minimize environmental impact, such as recycled and renewable resources. However, sustainability must not compromise product protection and shelf life. Rigorous testing is crucial to validate the performance of these novel packaging solutions. Maintaining product integrity, particularly in the food and pharmaceutical sectors, the physical and mechanical integrity of sustainable packaging is paramount. Comprehensive testing ensures robust protection throughout the supply chain. Tensile Strength and Elongation: These tests assess the material's ability to withstand stretching forces. Tensile strength measures the maximum stress a material can endure before breaking, while elongation quantifies the extent to which it can stretch. These properties are critical for packaging that must resist tearing or puncturing during handling and transportation. Seal Strength: This test evaluates the integrity of package seals, ensuring they can withstand forces without breaking or peeling. Strong seals are vital for maintaining product freshness and preventing contamination. 1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Tear Resistance: this test measures the force required to continue a tear in a material. This is very important to prevent packaging from ripping open during transport or consumer use. Puncture Resistance: This test measures the material's ability to resist penetration by sharp objects. It’s crucial for packaging that may encounter rough handling or sharp edges during transit. Labthink C610H Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture...

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Bursting Strength: This test evaluates the material's resistance to pressure, particularly relevant for flexible packaging like pouches and bags. It measures the pressure required to rupture the material, ensuring packaging can withstand internal forces without failure. Coefficient of friction: this test measures the kinetic and static friction of the packaging material. This is very important for packaging that will be used in automated packing lines, or stacked in warehouses. Beyond physical and mechanical properties, maintaining...
