Food Package Testing

Date:2009-4-22 17:04:00

The purpose of food package testing is to check whether the packaging materials are processable, to guarantee the package can protect the food. The most important elements of this are guaranteeing the shelflife of the food, attracting consumers’ attention with the appearance of the Package and guranteeing Packages’ properties during full transportation.

To meet the demands for food packaging testing, and to help food companies and food Packaging companies with quality testing of the food Packaging testing, Labthink Instruments 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), vapor (e.g. water vapor) and other infiltrations. Barrier property is the important factor affecting 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 includes 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 such as 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 includes XLW, XLW(B), XLW(M), XLW(PC)and XLW(G)
HST-H3 heat seal tester and the luxury model RTD-R2 gradation heat-sealing instrument
Food package testing instruments for leak property

Sealing property testing can guarantee the completeness of the whole package and avoid leakage and deterioration by inferior sealing property.

MFY-01 leak tester
LSSD-01 leak and seal strength detector
Food package testing instruments for headspace gas analysis

The 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 and mixing proportion in the package rapidly and accurately in production lines, warehouses, laboratories and other occasions, thereby guiding the production and ensuring the shelf life of products.

Food package testing instruments for impact resistance property

Shock resistance property testing of packaging materials can guarantee the effective protection of the contents. Shock 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. The SLY-S1 tearing tester complies with the 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 easy opening 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 and 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.
