At the heart of effective and sustainable packaging design and performance are the component materials. The physical properties and sometimes chemical properties, of the packaging materials need to be well understood by packaging engineers to aid in the design process. We offer a wide variety of testing options when it comes to testing packaging materials. Capabilities include physical strength testing, packaging material qualification and identification and characterizing material response to fatigue. Information gathered from these tests help you plan the optimal packaging material choice in specific applications.

Our cGMP and ISO 17025 laboratory offers testing for Packaging Materials Mechanical Strength Testing, Material Qualification and Identification, Quality Control Testing and Product Performance Tests. A few of our routine packaging material tests are summarized below.

Flexure Testing

The most common, cost effective, and reliable of the packaging material strength tests for brittleness flexure. Methods like ASTM D780 cover the determination of flexural properties of unreinforced and reinforced plastics in three and four point bends. For flexible barrier materials – flexible durability (Gelbo Flex) testing is outlined in ASTM F392.

Compression Testing

Packaging materials behave differently in compression than they do in tension, so it can be important to perform tests which simulates the conditions the packaging material will see in actual use. Top load compression testing evaluates the package performance of material – giving an indication of final packaging performance in storage and transport or helps refine the final packaging material selection.

Tensile Testing

One of the most common ways of characterizing material strength is tensile testing. Packaging material is subjected to linear stress until failure or a critical attribute is attained. Tensile testing can be performed on many types of packaging materials – information about yield strength, ultimate tensile strength, modulus of elasticity (stiffness), elongation can be gathered from methods such as ASTM D882 and ISO 527.

Puncture & Impact Testing

Common means to assess the ability of film and packaging materials to withstand penetration forces include puncture and impact testing. The rate of energy delivered effects material properties – there are multiple packaging material test methods to help define material properties under controlled condition. Slow Rate Penetration via ASTM F1306 will yield a much different result that high speed pendulum impact test such as ASTM D3420. In concert with puncture and impact testing, Tear Testing helps characterize the energy required to propagate a tear in packaging material.

Barrier Properties

To characterize adsorption, dissolution, diffusion, and desorption of packaging materials, package testing for Oxygen Transmission Rate or OTR via ASTM D3985 or ISO 15105-2 and Water Vapor Transmission Rate or WVTR via ASTM F1249, ISO 15106-2 and ASTM E96 can help you plan the optimal packaging material choice for specific applications to maximize preservation and prolong the shelf life of your product.

Information gathered from these tests helps engineers select the optimal packaging material choice in specific applications – be it a lifesaving pharmaceutical, sterile medical device or consumer product packaging.
