    Seal Strength/Peel Software

    A comprehensive peel strength and heat seal application is included with the instrument. The operator can enter a variety of peel strength parameters designed to support most international peel test and heat seal international standards. Selectable units, pre-peel and peel distance settings allow flexible test method set-up and storage. Results include average, maximum, minimum and standard deviation of an individual peel test. The 32-76e also provides result and test curve data output to GraphMaster Plus, PC-based software for data collection, test curve analysis and results storage. A selection of test fixtures is available to meet most peel applications.

    T-Peel Fixture is designed to measure the adhesive force of a heat seal or adhesive bonded substrate. The fixture attaches directly to the moving arm of the 32-76 Friction/Peel tester. A second clamp attaches directly to the instrument base. Included is one set (2) of test clamps, 30.5 mm (1.5 inch) wide, capacity is 100N.

    Meets the following standards:

    • ASTM D1876 T-Peel Test
    • ASTM F 88 Seal Strength of Flexible Materials

    180-Degree Peel Fixture measures the release strength of a label or peeling strength of an adhesive substrate. The fixture includes one set (2) of test clamps. One clamp is attached to the load cell with a clamping width of 50.8 mm (2.0 inch) wide, maximum capacity 100N. A second clamp is attached to the instrument base, maximum sample width is 125 mm (5 inch). With this fixture, release strength of labels and tapes can be performed. Typically, the label or tape is attached to a rigid backing.

    Meets the following standards:

    • PSTC-101 International Standard for Peel Adhesion of Pressure Sensitive Tape
    • ASTM D 3330 Standard Test Method for Peel Adhesion of Pressure-Sensitive Tape
    • FINAT1- Peel adhesion 180

    Heated Platen Option

    During the manufacture and converting process of plastic films, the material is subjected to elevated temperatures. When using a heated platen, it is common that the heated surface for most plastic films will produce an increase in COF. Normally a temperature increase will influence the friction of the packaging material. However, not all films will react in the same way to an increase in temperature. To measure this behavior, the 32-76e Friction/Peel tester is available with an optional heated platen. The temperature can be set from ambient to 162° C (325° F). The heated platen option can easily be installed in the field on an existing 32-76e unit (Part # 32-76-08). The heated platen option meets ASTM D 1894 standards for friction testing at heated temperatures.

     GraphMasterPro™ is a Windows™ based software data collection program capable of providing test curve analysis, result data, data storage, exporting and printed reports. The software automatically captures individual test results and/or raw data. In addition to collecting data from instruments manufactured by Testing Machines Inc. and Buchel BV, GraphMasterPro™ can be configured to communicate with instruments manufactured by other instrument suppliers.
