This test helps in determining the strength of paper, solid board and corrugated board. Bursting strength is usually quoted in kg/cm 2.
Test Method: BS 3137, BS 2922:1 and International standard ISO 2758 and ISO 2759.
This test helps in determining the tensile strength of paper, paperboard, etc. A tensile strength test is a mechanical test performed on packaging materials to determine the maximum load that can be applied to a material before it ruptures. This test can be used to measure the tensile strength of paper, board, and plastics. The material will show elastic behaviour up to a certain point and then rupture. This test can be adapted to different needs – it can also be used to measure the strength or elongation of a material and its tearing resistance and the force required to separate the seal. All these give a measure of the strength of the material. Test Method: IS: 1060
Thermal shock assesses the resistance of packs to sudden changes in temperature. The packs are given a specified number of temperature cycles between a very low and extremely high temperature, within a short period of time.
Thermal shock refers to a very high rate of temperature change, typically 30°C per minute or higher and is appropriate for testing packaging, aircraft parts, military hardware or electronics destined for rugged duty. Because almost all products are subject to shipping, this test may be appropriate to any part that will have to withstand an abrupt temperature change in a short period of time, such as a transition from a warm warehouse to a freezing roadside while being loaded onto a truck.
Test Method: BS EN 60068-2-14:2000
This test can assess the performance of filled packages when subjected to vibrations during transit. Vibration testing is the shaking of a product or packages to determine its ability to survive in real-world conditions.
Vibration testing on a package or product is performed to simulate one of three environments: Transportation environment, Operating environment and Storage environment of sensitive products.Test Method: ASTM D999, ASTM D3580, ASTM D4728, ISO 8318, ISO 2247, ISO 9022-10, ISO 9022-15, ISO 9022-19
This test helps in determining the co-efficiency of static and kinetic friction tests of plastic films, textiles, and paper, as well as peel strength tests of adhesive laminated products. Peel tests are widespread and determine that a medical device package design is valid, pressure-sensitive labels are manufactured correctly, and office supplies, electronics, and other packaging and adhesive products are operating as expected. A peel test measures the force, typically the peak force required to separate two adhered materials at a specified test speed over a specified length and angle.
This test helps in determining the Edge Crush, Flat Crush, Pin (Ply) Adhesion of Corrugated Board and Ring Crush. The liner and the media combination (3/5/7 Ply, etc) can be tested for the Edge Crush test value. Higher Edge Crush Test value will ultimately give a finished box of high compressive strength.
This test is designed for adhesives, adhesive tapes, adhesive products, and related industries. It is applicable in the holding power test of pressure-sensitive adhesive tapes. Adhesion testing is often associated with adhesives, tape, sealants, laminates, electronics, cosmetics, medical device packaging, general packaging seal strength and applications where bond strength measurement is critical for research and quality control applications. Stud pull coating adhesion testing, for instance, is a very common test used in microelectronic coatings or other forms of “thin-film” application on rigid substrates. Test Method: ASTM D3654
This test helps in determining the bending capacity of aboard. Due to the board’s brittle nature, multi-layer ceramic capacitors are more prone to mechanical stress than other components used in surface mounting. One of the most common causes of capacitor failure is directly attributable to the bending of the board after solder attachment. Excessive bending will create mechanical stress within the ceramic capacitor that, if sufficient, can result in mechanical cracks.
Accelerated Aging is commonly used in the medical device industry to “speed up” the effects of time on a Sterile Barrier System to establish shelf-life parameters. The Accelerated Aging process is based on the relationship of temperature and reaction rate where an increase in temperature increases the reaction rate and is approximated by the Arrhenius Equation.
This test helps in determining the impact resistance of the film, sheet, and laminated materials. The weight required to cause 50% of tested films to fail by impact from a falling dart under specified testing conditions. Impact resistance is only partially thickness dependant, as a result, impact values cannot be normalized by thickness without producing misleading data. Test Method: ASTM D1709
This test helps in determining the average force required to propagate a single-rip tongue-type tear starting from a cut in paper, cardboard, plastics, non-woven, and woven fabrics, with proper configuration. Internal tearing resistance is the force perpendicular to the plane of the paper sheet required to tear multiple plies through a specified distance after the tear has been started. Tear-growth resistance is a quality criterion used by paper-manufacturers during the final inspection and by processors in goods inwards checks. A tear test is completed in seconds, making electronic acquisition and evaluation of test data a logical choice. Test Method: IS: 1060
