The sterilization grade gauze pad packaging inspection items mainly include: barrier performance test (gas permeability test and water vapor transmission test), friction coefficient (material surface slip performance), tensile strength and elongation, peel strength, heat seal Strength (heat sealing strength), sealing and leak detection, tear resistance, print quality inspection, etc. Labthink (Jinan Languang Electromechanical Technology Co., Ltd.) combines the requirements of sterilized gauze pad packaging production enterprises. The sterilized gauze pad packaging and finishing information is as follows, in order to help the quality inspection of sterilized gauze pad packaging enterprises. . First, the sterilization grade gauze pad packaging barrier performance test Sterilization grade gauze pad packaging barrier property refers to the barrier effect of packaging materials on gas (such as oxygen), liquid (water vapor) and other permeate. Barrier performance is an important factor affecting the quality of a product during shelf life. The instrument information list is as follows: 1, PERME-DM2/330 double-detection gas permeability tester: differential pressure and equal pressure double test for plastic film, composite film and other film, sheet material and finished container gas permeability test. Three-chamber independent, automatic, temperature control, arbitrary temperature data fitting, support LAN data centralized management, patented products. 2, PERME-OX2/230 Oxygen Transmission Rate Test System: Coulomb principle, isobaric test of the oxygen permeability of film, sheet material and packaging containers such as bottles, bags, cans and boxes. Host and satellite mode, one host can be connected to nine satellites, and 30 samples can be tested simultaneously. 3, VAC-V series differential pressure gas permeation instrument is used for the measurement of the gas permeation amount of O2, N2 and CO2 in plastic film, sheet, composite film and other materials. The principle of differential pressure method. This series has VAC-V1, VAC-V2, VAC-V3 and other models. 4, PERME-W3/330 Water Vapor Transmission Rate Test System: For the determination of water vapor transmission rate of films, sheet materials and packaging containers such as bottles, bags, cans and boxes. Host and satellite mode, one host can be connected to nine satellites, and 30 samples can be tested simultaneously. 5, TSY-T series moisture permeability tester: test of water vapor transmission rate of various packaging materials and polymer products such as film and composite film; temperature control, automatic control; computer monitoring and weight method. This series has TSY-T1H, TSY-T1L, TSY-T3 and other models. Second, the sterilization level gauze pad packaging strength test The sterilization strength of the sterilized gauze pad includes the tensile strength of the packaging material, the peel strength of the composite film, the heat seal strength, the tear strength, and the puncture resistance. Tensile strength means that the material is subjected to a large stress value of zui before being broken. The detection can effectively solve the damage and breakage of the package caused by the external force due to insufficient mechanical strength of the selected packaging material. The peel strength is also referred to as composite strength, and is a joint strength between layers and layers in the composite film. If the adhesive strength is too low, problems such as leakage due to interlayer separation during packaging use are extremely likely to occur. The heat seal strength is the strength of the seal. During the storage and transportation of the product, once the heat seal strength is too low, the heat seal is cracked and the contents are leaked. Puncture resistance is an indicator of the ability of a package to resist the penetration of hard objects. The corresponding test instrument information is as follows: 1, XLW series intelligent electronic tensile testing machine: film, composite film, adhesive, adhesive tape and other peeling, tensile test, heat sealing strength test, professional test of tear performance. The series has XLW, XLW (B), XLW (M), XLW (PC), XLW (G) and other models. 2, BLD-200S electronic peeling test machine: peeling, tensile test, heat sealing strength test of film, composite film, adhesive, adhesive tape, etc.; standard specification 200N (100N, 50N, 30N), micro-play, computer communication interface. 3, HST-H3 heat seal tester: sample preparation for film heat seal strength test, pressure, temperature, time adjustable. It adopts single-chip control and intelligent operation; the temperature adopts PID high-precision components to ensure accurate and reliable temperature. 4, RTD-R2 heat sealing gradiometer: It can prepare samples of plastic film, flexible packaging composite film and other materials at 5 sets of independent temperature at one time, and heat-sealed five sets of samples at a time, high efficiency. Third, the sterilization grade gauze pad packaging sealing performance test The sealing performance test of the sterilized gauze pad package ensures that the seal of the entire product package is intact, preventing leakage due to poor sealing performance of the product. 1. MFY-01 Sealing Tester: Vacuum is used in the vacuum chamber for reliability testing of packaging seals. Microcomputer control, panel operation, digital setting test parameters, fully automatic test 2, LSSD-0 leakage and seal strength tester: packaging bag, plastic bottle, packaging container heat seal strength and seal integrity test, test process intelligent, liquid crystal display, statistical communication; positive pressure principle Fourth, the analysis of the top air body of the sterilized gauze pad package HGA-01 top air analyzer is used for the determination of oxygen, carbon dioxide gas content and mixing ratio in sealed packaging bags, bottles, cans, etc. It is suitable for fast and accurate in the packaging line in warehouses, warehouses, laboratories, etc. The content and proportion of the gas components are evaluated to guide production and ensure that the shelf life of the product is achieved. Five, sterilization grade gauze pad packaging impact resistance test Test the impact resistance of sterilized gauze pad packaging to ensure that the selected packaging material is effective in protecting the product. The impact resistance test has two test methods: dart impact and pendulum impact. BMC-B1 Dart Impact Tester: A free dart test method for determining the impact mass and energy of a damaged or damaged plastic film or sheet at a given height. FIT-01 film impact tester for the determination of impact resistance of plastic film, sheet, composite film, aluminum foil, etc. The hemispherical punch of the film impact tester impacts at a certain speed and passes through the film sample, measuring the punch The energy consumed is used to evaluate the anti-pendulum impact capability of the film. Sixth, sterilized gauze pad packaging tear performance test: The packaging of the sterilized gauze pad package may be torn by external force during storage and transportation. The sufficient tear propagation resistance can reduce the tear transmission and avoid the package leakage. SLY-S1 Tear Tester: Elemendorf method for tear resistance testing of films, sheets, paper, cardboard, etc. Seven, sterilization grade gauze pad packaging friction coefficient (surface slippery) The inner and outer surfaces of the sterilized gauze pad package should have suitable slip properties to ensure good openness and smooth transport and packaging on high speed production lines. 1.
