Ensuring Packaging Quality: Understanding Material Testing at Nelipak Laboratory Services

In the world of packaging, the importance of materials cannot be overstated. From ensuring durability to maintaining product integrity, the materials used in packaging play a crucial role. Nelipak Laboratory Services is a vital resource, offering an array of material testing methods aimed at evaluating packaging materials for various attributes. This article delves into three key methods performed at Nelipak Laboratory Services that shed light on the quality and suitability of packaging materials.

1. Gelbo Flex Testing

Gelbo Flex testing, conforming to ASTM standard F392/392M, is an essential test method that determines the flexural resistance of flexible barrier materials. During this test, materials undergo a series of twists and compressions for a specified duration. This process simulates the strains encountered during routine use. Following the strain, a colored dye is applied to reveal the number of pinholes created by the testing. The fewer the pinholes, the stronger the material—an indicator of its durability and suitability for packaging applications.

2. Coefficient of Friction (COF) Testing

Also referred to as a slip test, COF testing is crucial for materials involved in automated production processes or product stacking. The test performed at Nelipak to ASTM D1894 involves preparing a specimen of the film and wrapping it in a sled to measure the force required to pull it along a surface. This test aids in designing automated processes, ensuring that finished products can stack efficiently and securely, facilitating streamlined manufacturing operations.

3. Tensile Testing

Tensile testing, based on ASTM Standard D882, evaluates the mechanical properties of films. This method determines key characteristics like tensile yield, strength, elongation, and modulus. A sample is subjected to controlled tension until it reaches the point of failure, providing crucial data about the material's strength and elasticity. Understanding these mechanical properties is pivotal in selecting materials that can withstand the stresses of packaging and transportation without compromising product safety.

Nelipak Laboratory Services prides itself on being a fully accredited testing laboratory, offering not only these methods but a plethora of others, ensuring comprehensive evaluations of packaging materials.

Material testing remains a cornerstone in the design and validation of packaging materials. With Nelipak Laboratory Services' expertise and accredited methodologies, businesses can confidently select materials that meet stringent quality standards, ensuring their products are packaged securely and reliably for consumers worldwide.
