    Cosmetic PackagingThe testing items mainly include: barrier performance test (gas permeability test and water vapor permeability test), coefficient of friction (material surface smoothness performance), tensile strength and elongation, peeling strength, heat sealing strength (heat sealing strength), sealing and leakage test, impact resistance test, thickness test, solvent residue test, printing quality test and so on. Jinan Labthink Electromechanical Technology Co.labthink(Labthink) combined with cosmetic packaging testing needs, special cosmetic packaging testing instruments to organize information as follows, in order to help the quality of cosmetic packaging and dairy companies to help a hand.

    I. Cosmetic Packaging Testing Instrument Barrier Property Testing
    Barrier property refers to the barrier effect of packaging materials on permeants such as gases (e.g. oxygen) and liquids (water vapor). Barrier property is an important factor that affects the quality of the product during the shelf life. Instrument information is listed below:
    1
    ,?permedense-dm2/330Dual detection method gas permeability tester: differential pressure and isobaric dual method test, for plastic film, composite film and other film, sheet materials and finished container gas permeability test.

Host, satellite machine mode, a host can be connected to nine satellite machines, can realize thirty specimens at the same time testing.
    5
    ,?tsy-tMoisture permeability tester series: water vapor transmission rate test for various packaging materials and polymer products such as film, composite film, etc.; temperature control, fully automatic; computer monitoring, gravimetric method principle. This series hastsy-t1h(math.) genustsy-t1l(math.) genustsy-t3and other models of products.

    Second, cosmetic packaging strength testing
    Strength testing includes packaging material tensile strength, composite film peeling strength, heat sealing strength, tearing strength, puncture resistance and other indicators. Tensile strength refers to the maximum stress value of the material before pulling off..?Through the test can effectively solve because of the selection of packaging materials mechanical strength is not enough, and in the external force produced by the packaging breakage and fracture. Peel strength, also known as composite strength, is to detect the adhesive strength between the layers in the composite film, if the adhesive strength is too low, it is very easy to be separated from the layers in the use of packaging and leakage and other issues. Heat seal strength is to detect the strength of the seal, in the preservation and transportation of products, once the heat seal strength is too low, it will lead to heat sealing at the crack, content leakage and other problems. Puncture resistance is an indicator to evaluate the ability of packaging to resist puncture by hard objects.
    The information of the corresponding testing instruments is as follows:
    1
    ,?xlwSeries of intelligent electronic tensile testing machine: film, composite film, adhesive, adhesive tape, such as peeling, tensile strength test, heat bonding strength test, tearing performance professional test. The series hasxlw(math.) genusxlw(b).xlw(m).xlw(pc).xlw(g) and other model products.
    2
    ,?bld-200sElectronic peeling test machine: film, composite film, adhesive, adhesive tape, such as peeling, tensile test, thermal bonding strength test; standard specifications200n(100n,50n,30n), microtyping, and computer communication interfaces.
    3
    ,?hst-h3Heat Seal Tester: Specimen preparation for film heat seal strength test with adjustable pressure, temperature and time. Adopting single-chip computer control, intelligent operation; temperature adopts thepidHigh-precision components ensure accurate and reliable temperatures.
    4
    ,?rtd-r2Heat Seal Gradient Instrument: It can prepare plastic film, flexible packaging composite film and other materials at one time in the5Groups of specimens at independent temperatures, heat sealing five groups of specimens at a time, high efficiency.

    Third, cosmetic packaging sealing performance test
    The sealing performance test can ensure that the entire product packaging seal is intact, to prevent the product sealing performance is not good, and the leakage caused by the deterioration of the packaged goods.
    1
    ,?mfy-01Sealing Tester: It adopts vacuum chamber to extract vacuum, and is used for package sealing reliability performance test. Microcomputer control, panel operation, digital setting of test parameters, fully automatic test.
    2
    ,lssd-0Leakage and sealing strength tester: bags, plastic bottles, packaging containers, heat sealing strength and sealing integrity of the test, the test process is intelligent, liquid crystal display, statistical communication; positive pressure principle

    Fourth, cosmetic packaging headspace air body analysis
    hga-01
    Headspace gas analyzer is used for the determination of oxygen and carbon dioxide gas content and mixing ratio in sealed bags, bottles, cans and other packaging parts; it is suitable for making a quick and accurate evaluation of the content and ratio of the gas components in the packaging parts in production lines, warehouses, laboratories and other occasions, so as to guide the production and ensure that the shelf life of the products can be realized.

    V. Impact resistance test for cosmetic packaging
    The impact resistance of packaging materials is tested to ensure that the chosen packaging materials can effectively protect the products. There are two test methods for impact resistance testing: falling dart impact and pendulum impact.
    1
    ,?bmc-b1Falling Dart Impact Tester: Free falling dart test method to determine the impact mass and energy of a plastic film or sheet when the specimen breaks under the impact of a free falling dart at a given height.
    2
    ,?fit-01Film Impact Tester is used for the determination of the impact resistance of plastic film, sheet, composite film, aluminum foil, etc. The hemispherical punch of the Film Impact Tester impacts and passes through the film specimen at a certain speed, and the energy consumed by the punch is measured, so as to evaluate the film's resistance to pendulum impact.

    VI. Cosmetic packaging tearing performance test:
    Packaging may be torn during storage and transportation due to external forces, sufficient tear expansion can reduce tear transfer and avoid packaging leakage.
    sly-s1
    Tear Tester: Ellemendorf method for testing the tearing resistance of film, sheet, paper, cardboard, etc.

    VII. Coefficient of friction of cosmetic packaging (surface slipperiness)
    The inner and outer surfaces of the film should have the right slip to ensure good openings and smooth conveying and packaging on high-speed production lines.
    1
