The purpose of food package testing is to check whether the packaging materials are processable, to guarantee the package can protect the food. Protection includes guarantee of the shelf life of the food, the appearance of the package to attract the consumersf attention, and to guarantee the packagesf properties during full transportation. To meet the demands for food packaging testing, and to help the food companies and food packaging companies on quality testing of of the food packaging testing, Labthink Instruments Co. Ltd. Integrates and introduces all relative food package testing items and instruments in this article.
Food Package Testing Instruments for Barrier Property: Barrier property, also called permeability, is defined as the barrier property of packaging materials on gas (e.g., oxygen), vappr (e.g., water vapor) and other infiltrations. Barrier Property is an important factor affecting the product shelf-life.
Relevant instruments are listed below:
- PERME-DM2/330 Differential and Equal Pressure Methods Gas Permeability Tester
- PERME OX2/230 Oxygen Transmission Rate Testing System
- VAC-V Series Differential Pressure Gas Permeability Testers includs VAC-V1, VAC-V2 and VAC-V3, etc.
- PERME@W3/330 Water Vapor Transmission Rate testing system
- TSY-T Series Water Vapor Permeability Tester includes TSY-T1H, TSY-T1L and TSY-T3, etc.
Food Package Testing Instruments for Strength: 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 broken. Peeling strength testing, also called complex strength testing, tests the bonding strength between the layers of laminated films. Hot seal strength testing is to test the strength of the seals. Pouch resistance is the index evaluating the anti-puncture strength of the package against rigid material. Relevant testing instruments are as follows:
- XLW Series Auto Tensile Testers
- HST-H3 Heat Seal Tester and the luxury model of RTD-R2 Gradation Heat-Sealing Instrument
Food Package Testing Instruments for Leak Property: Through the sealing property testing can guarantee the completeness of the whole package and avoid leakage and deterioration thereby by the inferior sealing property.
- MFY-01 Leak Tester
- LSSD-01 Leak and Seal Strength Detector
Food Package Testing Instruments for Headspace Gas Analysis: HGA-01 Headspace Gas Analyzer is used for the measurement of the content of oxygen, carbon dioxide and mixing proportion in the sealed bags, bottles, cans and other packages. It can be used to evaluate the gas components, content, mixing proportion in the package rapidly and accurately in production lines, warehouses, laboratories and other occasions, thereby to guide the production and ensure the shelf life of products.
Food Package Testing Instruments for Impact Resistance Property: Impact resistance property testing of packaging materials can guarantee the effective protection of the contents. Impact resistance property testing can be classified as dart impact and pendulum impact.
- BMC-B1 Falling Dart Impact Tester
- FIT-01 Film Impact Tester
Food Package Testing Instruments for Tearing Property: Tears and breakage of products in storage and transportation occurs because of external forces. Sufficient tearing resistant forces can reduce tearing and avoid leakage.
SLY-S1 Tearing Tester: complies with Elmendorf method, and is applicable in tearing resistance test of films, laminated films, foils, paper and paper boards.
Food Package Testing Instruments for Coefficient of Friction (Surface Smoothness): Proper smoothness of the two sides of the material can guarantee the good open easiness as well as smooth transportation and packaging in the assembly line.
- MXD Series of Coefficient of Friction Testers includes MXD-01, MXD-01A and MXD-02.
- FTP-F1 Friction/Peel Tester
Food Package Testing Instruments for Thickness: Thickness is the basic index to test films. Uneven thickness would influence the tensile strength and barrier property as well as the following processing.
- CHY-C2 Thickness Tester
- CHY-CA Thickness Tester
Food Package Testing Instruments for Printing Testing: This is to test the ink layer bonding force of the printed materials.
- Ink-layer Bond Strength: YGJ-02 Adhesive Tensile & Shear Tester and BLJ-02 Disk Stripping Tester co-works together.
- MCJ-01A Rub Tester
- RT-01 Rub Tester
Food Package Testing for Solvent Residual: Packaging bag solvent residual quantity directly links to the safety of users. Gas chromatograph, for the safety guarantee, is applied for resolution residual quantity testing.
- GC6890 Gas Chromatograph Tester
- GC7800 Gas Chromatograph Tester
