    Abstract: the fried products are very nutritious and contain a lot of vitamins, proteins and oil components, so it is necessary to strengthen the monitoring of packaging moisture resistance This paper uses Labthink blue light W3 / 031 water vapor transmittance tester to test the external water vapor barrier performance of the paper aluminum plastic packaging of the fry products, and introduces the basic process of the test, the principle of the test and the applicable scope of the test equipment, etc., which can be used as a reference for enterprises in selecting the test equipment and test methods of the water vapor performance Key words: fried products, high barrier, moisture resistance, weighing method, water vapor transmission rate, water vapor transmission rate test system 1 Meaning fried products refer to a kind of leisure food for people to eat in their spare time, such as melon seeds, broad beans, peanuts, walnuts, chestnuts, beans, etc., which are made of plant fruits through processing methods such as drying, drying, frying, etc Generally, the packaging of fry products uses plastic composite film, aluminum-plated composite film, aluminum-plastic composite film, paper aluminum-plastic composite film, plastic can and other packaging, and the packaging should have good moisture-proof performance Because the fry products are easy to absorb the water vapor components in the environment under the high humidity environment, resulting in the phenomenon of mildew and harrass, increasing the risk of product deterioration and taste change, and shortening Quality guarantee period Therefore, it is necessary to strictly control the barrier of packaging materials to water vapor to ensure the sealing of the finished product packaging Figure 1 Paper aluminum plastic packaging of fry products 2 The water vapor barrier test methods of domestic reference standards for composite film and sheet packaging are weighing method (cup method), electrolysis method, infrared method and humidity method The reference method standards are respectively GB / T 1037 test methods for water vapor permeability of plastic film and sheet cup method and GB / T 21529 The standard of this paper is GB / T 1037-1988 test method for water vapor permeability of plastic film and sheet Cup method 3 Three kinds of paper aluminum plastic packaging used in a food enterprise were tested 4 Test equipment: W3 / 031 water vapor transmittance tester independently developed and designed by Jinan Languang Electromechanical Technology Co., Ltd Fig 2 test principle of W3 / 031 water vapor transmissivity tester 4.2 scope of application (1) this equipment is applicable to the water vapor transmission test of plastic film, sheet, paper, paperboard, textile, non-woven fabric and other packaging Film materials: suitable for testing the water vapor permeability of various plastic film, plastic composite film, paper plastic composite film, geomembrane, coextrusion film, aluminized film, aluminum foil, aluminum foil composite film, waterproof and breathable film and other film materials; Sheet materials: suitable for the water vapor transmission test of various engineering plastics, Rubbers, building materials (waterproof materials for construction), thermal insulation materials and other sheet materials, such as PP sheet, PVC sheet, PVDC sheet, nylon sheet, etc.; textiles, non-woven fabrics are suitable for the water vapor transmission test of textiles, non-woven fabrics and other materials; In addition, it is also suitable for testing vapor permeability of materials such as LCD panels, solar backboards, aseptic protective films and facial mask (2) the equipment can meet many national and international standards, such as GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, ISO 2528, DIN 53122-1, JIS Z0208, and "00092003" 4.3 test range of equipment parameters: 0.1 ~ 10, 000G / M 2 · 24h sample quantity: 1 ~ 3 pieces (data are independent) resolution: 0.0001 g test temperature range: 15 ℃ ~ 55 ℃, temperature control accuracy ± 0.1 ℃ test humidity range: 10% RH ~ 98% RH (standard 90% RH), temperature control accuracy ± 1% RH by matching Lystem TM Laboratory data sharing system, test data and equipment information can be reported simply by setting and operation, and it is easy to realize centralized and systematic management of laboratory test data 5 Test process (1) use samplers to cut three samples with diameter of 74 mm (2) Install the sample on the moisture permeable cup and close the glass sealing door (3) Set the sample name, sample thickness, test temperature, test humidity and other parameters (4) Start the air source and click the "start test" option (5) After the test, the instrument automatically calculates and displays the test results 6 The results showed that the transmittance of water vapor was 3.5612 g / (M 2.24 h), 5.1637 g / (m2.24 h) and 0.8231 g / (m2.24 h), respectively 7 Conclusion W3 / 031 water vapor transmittance test system is a professional instrument for measuring the water vapor transmittance of film The equipment is simple in operation, high in accuracy and repeatability, and can accurately reflect the moisture resistance of packaging By comparing the test results of three samples, we can see that the third sample has good moisture resistance Zui The packaging of fried products also needs to pay attention to oxygen resistance, sealing performance, heat sealing strength and other properties to prevent oxidation and deterioration of products and extend the shelf life of products To learn about the relevant testing equipment and testing services, you can log in Jinan Languang company to check the specific information or call for consultation The more you understand, the more you trust!
