Dairy Package Testing Instruments for Strength

An article by admin    No Comments

Strength testing includes index testing like material tensile strength testing, peeling strength testing of laminated films, hot seal strength testing, tearing strength and pouch resistance testing. Tensile strength is the maximum strength value just before the material is snapped. Through testing, the package damage and rapture caused by external forces and insufficient packaging material mechanical strength can be resolved effectively. Peeling strength testing, also called complex strength testing, tests the bond strength between the layers of laminated films. If the bond strength is too low, leakage is easily caused by separation among the layers. Hot seal strength testing is to test the strength of the seals. During storage and transportation of products, low hot seal strength will cause problems such as rending and leakage. Pouch resistance is the index evaluating the anti-puncture strength of the package against rigid material.

Relevant testing instruments are as follows:

A. XLW Series Auto Tensile Testers: are for the peeling, tensile, heal seal and tearing tests of films, laminated films, adhesives and tapes. This series of products includes XLW，XLW（B），XLW（M），XLW（PC）and XLW（G）.

B. BLD-200S Auto Stripping Tester: is for the peeling, tensile and heat seal testing for films, laminated films, adhesive and tapes. The standard specifications are 200N (100N, 50N and 30N); mini-printer and computer connective.

C. HST-H3 Heat Seal Tester: is for the specimen preparation for the heat seal strength testing of films. Testing pressure, temperature and time are adjustable. This instrument adopts microcontroller for intellectual operation and PID high precision components for temperature so as to ascertain accurate temperature.

D. RTD-R2 Gradation Heat-Sealing Instrument: can prepare five groups of plastic films or flexible packaging laminated films simultaneously under five independent temperatures; and seal five groups of specimen simultaneously and efficiently.
