EVOH Barrier film oxygen transmission rate testing

Intelligent Leakage Tester uses the working principle of pressurizing samples to test the sealing strength and integrity of packaging materials. It is suitable for food and medicine packaging materials such as flexible, rigid, porous and laminated aluminum foil. There are a variety of test modes, which can comprehensively evaluate the tightness and integrity of packaging materials. It has wide applicability, complete functions and accessories,which is comply with ASTM, ISO and GB standards. At the same time, our company provides suitable accessories and services for different samples  

  ZF3600 Full-automatic Total Migration Tester is applied to determinate the dissolution amount of packaging materials in different simulant soaking solutions.  

To test the tensile strength, peeling strength, heat sealing strength, tearing strength, piercing strength of plastic film, composite film, tape, soft packaging material, rubber sheets, paper, non-woven fabrics and other packaging materials

Coefficient of friction testers is used to test the coefficient of frictionof plastic film, thin sheet, paper and so on, widely used in packaging industry, film-making companies and packaging material inspection agencies.

Test Principle Firstly submerge the specimen in the water in the vacuum chamber, and then evacuate the vacuum chamber to form differential pressure between the inside and outside of specimen. The seal property can be obtained by observing the steady progression of bubbles from the specimen or observing how the specimen expands and restores to its original shape after vacuum release.

Heat Seal Tester apply to test the temperature, pressure, time and strength for heat sealing of various plastic films, composite film, aluminum foil and so on, widely used in industries of , food, pharmaceuticals, inspection agency, research institute and so on.

Application It is to test the filtering efficiency of particulate protective masks and medical masks and to determine the resistance of ordinary fabrics and medical protective masks to the constant flow of airflow.

1 Function Ozone in the atmosphere is very little, while it’s a major factor in rubber cracking, the product simulate and enhance atmospheric ozone condition to study the role of ozone on the rubber, and to rapid identificate and evaluate rubber resistance for ozone aging and anti-ozone agent protection. According to“GB / T7762-2003 Test Method for Static Tensile Test of Ozone Resistance Cured Rubber or Thermoplastic Rubber”,“GB / T2951.21-2008 General Test Method for Insulation and Sheathing Material of Cable”,“GB / T 11206-2009 Rubber Aging test surface cracking method”, and other relevant standards of the test method. 2.1 Structure  All-in-one machine 2.2 Material a) Inner chamber: SUS304 stainless steel plate b) External chamber: SUS304 stainless steel plate or baking finish.
