Accelerated & Real Time Aging
Accelerated Aging TestingASTM F1980
Test specimens are exposed to elevated environmental conditions for fixed periods of time. Accelerated Aging simulates the effects of real time aging over shorter time frames and allows the manufacturer to predict the real time performance of the product and package.
Accelerated Aging Testing can be done with or without humidity, using various aging temperatures specific to customers’ individual needs. Conditions range from 40°C to 60°C, 15% to 90% RH.
Material Analytical Testing
Differential Scanning CalorimetryISO 11357-1 & ISO 11357-3
Is a thermo-analytical test which characterises the thermal behavior and enthalpy of a polymeric material to measure properties such as transition onset temperatures, melt temperatures and glass transition temperature of polymers.
FTIR SpectroscopyASTM E1252 & ASTM E573
An analytical test where infrared light passes through a specimen and results in a spectrum. The spectrum provides a chemical “fingerprint” unique to that specimen. It can be used to identify unknown samples or determine the quality / consistency of a sample.
Material Testing
Tensile TestingASTM D882
These tests are used to determine the mechanical properties of the test substrate such as tensile strength, elongation and the resilience of the materials to breakage. The sample is subjected to a known and controlled tension until failure.
Slip Testing / Coefficient of FrictionASTM D1894
Slip Testing is used to determine the static and kinetic coefficients of friction of materials. Slip testing properties are important to consider when looking at automated filling processes and stacking properties of filled packages.
Gelbo Flex TestingASTM F392
Determines flexural resistance of a material by applying repetitive strain through a combination of twisting and compression motion. After the flexing process the samples are tested for pinhole damage by means of a dye penetration testing.
Slow Rate Puncture TestingASTM F1306
Provides data on how well a product or material can withstand penetration forces required to puncture flexible packaging. The test allows a flexible barrier sample to be characterised for slow rate penetration resistance with a driven probe. The test is performed by applying a biaxial stress at a single test velocity to the sample until perforation occurs.
Bendtsen Porosity TestingISO 5636-3
Determines the air permeance of a porous material by measuring the resistance of airflow through the material.
Breaking Force & Elongation of Textile FabricsASTM D5035
Determines the resilience of a material by applying a force until the sample breaks.
Dart Drop Impact TestingASTM D1709
Packaging must be able to withstand sudden impact, preventing functional failures and damage. The test determines the energy needed to cause a plastic film to fail under the impact of a free-falling dart.
Yield TestingASTM D4321
Yield Testing is used to determine mass per unit area of flexible materials, paper and board.
Determination of GrammageISO 536 Paper and Board
Yield Testing is used to determine mass per unit area of flexible materials, paper and board.
Package & Seal Integrity
Seal Strength Testing ASTM F88
Establishes the strength of a seal on flexible packaging materials such as blisters, pouches and header bags. Tests can be either supported or unsupported depending on the customer requirements.
Seal Strength testing can be one of the following:
Technique A – Unsupported.
Technique B – Supported 90°C – by hand.
Technique C – Supported 180°C – backing plate.
Burst Testing ASTM F1140
Determines the seal strength by means of internal pressurization. The test provides results for failure pressure and identifies the weakest points in the package and can be carried out on open or closed packages.
Dye Penetration Testing ASTM F1929 & ASTM 3039
Examines the seal integrity between materials for imperfections such as channels in the seal or a breach of the seal. A specific dye is left in contact with the seal for a specified time and then visual inspection is performed.
Bubble Leak Testing ASTM F2096
Verifies the integrity of the sterile barrier system. During Bubble Leak Testing, the package is internally pressurized while submerged under water and observed for a stream of bubbles that would indicate a failure area.
Transportation Testing
Conditioning ASTM D4332
Conditioning of specimens ensures that they are exposed to a range of specific temperatures and humidity in a predetermined cycle, so that environmental conditions can be taken into consideration for further tests. Conditioning Testing is normally used in conjunction with Transportation Testing to simulate various climatic changes that it may encounter during distribution and storage.
Drop Testing ASTM D5276
Drop Testing evaluates the:
- Capability of a container to withstand the sudden shock resulting force from a free fall
- Capability of a container and its inner packaging to protect the contents
Fixed Displacement Vibration ASTM D999
Test specimens are subjected to a constant fixed vibration frequency, to stimulate repetitive shocks encountered during transportation.
Compression Testing ASTM D4577, ASTM D642
Testing simulates Vehicle / Warehouse stacking forces based on the mass and dimensions of the samples. The test measures the ability of the containers to resist external compressive loads.
Random Vibration ASTM D4728
Test specimens are subjected to random vibrations and varying frequencies to simulate truck, air and rail transport.
High Altitude Simulation ASTM D6653
Simulates the effects of high altitude / low pressure exposure during travel by non-pressurized aircraft or over mountain passes. The packaging systems are subjected to a controlled vacuum. Required only where packages are sensitive to low pressure i.e. non- porous material.
Concentrated Impact Testing ASTM D6344
Concentrated Impact Testing evaluates the ability of lightweight single wall corrugated shipping containers to resist concentrated low-level impacts.
