With the improvement of living standards and lifestyle changes, people's leisure, consumption and emotional sustenance have also undergone major changes, and the pet industry has risen rapidly. Today, as pets become more and more important, the quality control requirements for pet foods are increasingly regulated. In addition to the quality and safety of pet food itself, the detection of barrier properties of pet food packaging has increasingly attracted the attention of pet food manufacturers. Labthink is followed by a differential pressure gas permeation tester, a moisture permeability tester, and a description of the oxygen barrier properties of pet food packaging bags.
Barrier performance refers to the barrier effect of vacuum packaging materials on permeates such as gases and liquids. Barrier performance tests include both gas (oxygen, nitrogen, carbon dioxide, etc.) and water vapor transmission properties. Barrier performance is an important factor affecting the quality of products during the shelf life, and is also an important reference for analyzing shelf life.
(1) Oxygen permeability of pet food packaging bags
Pet food ingredients contain a lot of fat. If the packaging material has poor oxygen barrier properties, the food will be too much contact with oxygen, and the fat will be easily oxidized, resulting in spoilage. On the other hand, for some scented foods, The entry of air and the overflow of the aroma in the package will reduce the pet's satisfaction with the food. To summarize the relevant standards, the oxygen permeation test is tested in accordance with GB/T 1038-2000 Plastic Film and Sheet Gas Transmission Rate Test Method Differential Pressure Method. Labthink's VAC series of differential pressure gas permeation instruments are excellent in selection, and all indicators are superior to national or international standards. The performance is stable and reliable. In addition to the gas permeability detection function, it also has a diffusion coefficient and penetration. The test function of coefficient and solubility coefficient meets the research needs of analysis and improvement of the barrier properties of materials by scientific research institutions and colleges.
(2) Water vapor permeation in pet food packaging bags
If the pet food package does not have a very high water repellency, the food in the package is likely to agglomerate due to moisture, which can also cause microbial growth and endanger the health of the pet. To summarize the relevant standards, the water vapor transmission test is tested according to GB/T 1037-1988 Plastic film and sheet water vapor permeability test method cup method. The test conditions are temperature 38±0.6°C, relative humidity 90±2%. . Labthink's moisture permeability tester uses a high-precision load cell to improve test accuracy and effectively shorten the judgment time of the permeation balance during the test, thereby effectively shortening the test time. Secondly, the temperature and humidity control technology and the weighing technology are combined with the computer control technology to achieve the test weighing in the test environment, without manual intervention, so that the test process is completely free from external influences, the test results are more accurate, and the aluminum foil is completely satisfied. Requirements for moisture permeability testing of high resistance materials. In addition, the equipment is also available in single, three, six and twelve chambers to meet the needs of different customers.
Of course, after ensuring that the pet food packaging has passed the oxygen and water vapor barrier performance indicators, other indicators need to be controlled to ensure the quality of the products during the shelf life. For more information about related instruments, check the specific information. Jinan Languang Electromechanical Technology Co., Ltd. is willing to enhance exchanges and cooperation with enterprises and institutions in the industry.
Pet food packages are designed to protect food, prevent food from deteriorating and dampness, prolong the life of food as far as possible, and to take into account the quality of food. It is light and easy to carry when you go out with a pet, you can feed your pet at any time. In addition, its appearance is beautiful, and the price of the bag is not very high, Sunway produce this kind of pet food bag , we used food-grade material 100% , so you can use it safely.
