Control tester C632B

heat seallaboratoryfor the food industry

C632B Hot Tack Tester is designed to measure hot tack and heat-seal performance of plastic films, laminated films and other packaging materials, and to perform peel and tensile-at-break tests for adhesives, tapes, films, paper and other flexible materials.

Product features

• Multiple test modes in one instrument: hot tack, heat seal, peel and tensile tests.
• Digital P.I.D. temperature control for rapid attainment of set temperature with minimal fluctuation.
• Four force ranges available (standard 30 N; optional 50 N, 100 N, 200 N) with 0.01 N resolution and six test speeds to meet varied requirements.
• Complies with test speed requirements specified in GB/T 34445-2017.

Design & automatic sampling

• Automatic sampling for hot tack testing to simplify operation and improve data uniformity.
• Optional pneumatic sample clamping system.
• Automatic zeroing, error alert, overload protection and stroke protection for safe operation.
• Start manually or via pedal switch; anti-scald design for operator safety.
• Key components sourced from established manufacturers for reliable performance.

Operation & data handling

• Tests can be performed on the instrument or via dedicated software.
• Instrument can operate standalone without a computer; test data visible on the device.
• Data I/O ports provided for export and integration.

Test standards

• GB/T 34445
• ASTM F1921
• ASTM F2029
• QB/T 2358
• YBB 00122003

Applications

• Basic applications
  • Hot tack performance — plastic films, sheets and composite films (e.g. PE, PP, PET) used in packaging for food, pharmaceuticals and consumer goods.
  • Heat seal performance — plastic films, sheets and composite films.
  • Peel strength — adhesives and adhesive tapes.
  • Tensile strength — tensile tests of various films, sheets and composite films.
• Extended applications
  • Medical adhesives — peel and tensile tests for medical tapes and dressings.
  • Textiles, nonwovens and woven bags — peel and tensile strength tests.
  • Adhesive tapes — low-speed unwind/peel tests.
  • Protection films — peel and tensile tests.
  • Magnetic cards — peel tests of films and cards.
  • Bottle caps — opening-force tests for aluminum-plastic combination caps.
