1. Determination of the thickness of flexible packaging bags
(1) Standard requirements: GB/T6672-2001 "Metal measurement method for plastic film and sheet thickness measurement" This non-equivalent use ISO4593: 1993 "Plastic - film and sheet - thickness measurement - mechanical measurement method".
(2) Experimental equipment: The CHY-U thickness gauge of Sanquan Zhongshi is suitable for the determination of the thickness of films and sheets.
Thickness gauge
(3) Experimental method: The mechanical method is used to measure the contact method, and the measurement result refers to the result measured between the two measurement planes. The load applied to the sample should be between 0.5 N and 1.0 N.
2. Flexible bag tensile properties
(1) Experimental purpose: The tensile properties of plastics include tests of tensile strength, tensile fracture stress, tensile yield stress, and elongation at break.
(2) Standard requirements: GB/T 1040-1992 "Test method for tensile properties of plastics", GB/T13022-1991 "Test method for tensile properties of plastic films", ISO1184-1983 "Determination of tensile properties of plastic films"
Intelligent electronic tensile testing machine
(3) Experimental equipment: The XLW (PC)-500N intelligent electronic tensile testing machine produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. can meet the different specifications of the tensile strength, tensile fracture stress, tensile yield stress and fracture of the above specifications. Elongation and other indicators.
3. Flexible packaging bag friction coefficient
(1) Standard requirements: GB/T10006-1988 "Determination of friction coefficient of plastic film and sheet", ISO 8295-1986 "Determination of plastic - film and sheet - friction coefficient"
Friction coefficient meter
(2) Friction coefficient meter MXS-05A is suitable for measuring the static friction coefficient and dynamic friction coefficient of plastic film and sheet. It can also be used for the determination of the slip performance of cosmetics, eye drops and other daily chemicals.
(3) The test passes by placing the two test surfaces flat together, and moving the two surfaces relative to each other under a certain contact pressure, and measuring the force when the sample starts to move relatively and the force when moving at a constant speed. The coefficient of friction of the sample is obtained by calculation.
4. Flexible bag heat sealing strength
(1) Experimental purpose: Plastic film is used as a packaging material, and the packaged material is often encapsulated by heat sealing method. Whether a good seal is achieved or not, the quality of heat sealing is very important.
Heat seal tester
(2) Experimental equipment: The instrument commonly used in the laboratory is RFY-03 heat seal tester, which is a heat sealing test equipment that can set different temperatures, pressures and times. It can be used to test a certain material under certain conditions. Zui good effect.
(3) Standard requirements: QB/T 2358-1998 "Test method for heat sealing strength of plastic film packaging bags"
(4) Experimental method: The test is to clamp the two ends of the strip sample on the two clamps of the tensile test, and to stretch and destroy the zui value of the sealing part of the sample, which is the force value of the heat sealing. The result must be The force value used for the sample of unit length is expressed as the heat sealing strength. The force used is expressed in N/m.
5. Flexible packaging bag sealing performance
(1) Standard requirements: "GBT 15171-94 Flexible Package Sealing Performance Test Method" specifies the experimental method for sealing the flexible package.
(2) Experimental equipment: The flexible packaging bag tightness tester is developed and produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd., which specializes in testing the sealing of plastic film bags and composite tapes for food, medicine, cosmetics, industrial products and component packaging.
Flexible bag tightness tester
(3) Experimental method: The internal and external pressure difference is generated by the sample immersed in the vacuum chamber water, and the gas escape condition in the sample is observed to determine the sealing performance of the sample; or the vacuum chamber can be vacuumed to make the sample The internal and external pressure difference is generated, and the shape recovery and liquid infiltration of the sample after the expansion of the sample and the release of the vacuum are observed to determine the sealing performance of the sample.
Packaging quality is also an important control indicator for product safety. Therefore, manufacturers should use professional testing equipment to complete product quality control in light of actual needs. Article source Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd.
