The mechanical laboratory carries out tests to evaluate strength of materials in packaging to reveal any defects over time. Many tests may be offered including:
• Tensile strenght, pelability…according to FINAT FTM 1 and FTM2
• Charpy / Izod Impact according to NF EN ISO 179-2: Plastics - Determination of Charpy impact strenght - Part 1 : Non-instrumented impact test.
The following checks can be performed:
• Friction coefficients (slide film) according to NF T54-122: Plastics - Sheets - Determination of the slippage - Measuring of the friction coefficients
• The tensile strength (in temperature) according to ISO 527: Plastics - Determination of tensile properties
• Perforation Resistance according to NF XP T54-198 : Plastics - Industrial polymer-based films and sheets - Mono and multilayered films for packaging - Conventional test method for assessing the slow rate penetration resistance.
• The opening force packages
• Welding resistance according to NF T54-122: Plastics - Sheets - Assessment of the quality of a weld or bond between two sheets elements by a means of a tensile test
• The compressive strength of bottles
• The screwing or unscrewing couple of bottles or screw system
• The holding of the labels and checking the specifications of the tape for the shipping containers.
