Y310 2.0 Oxygen Transmission Rate Tester Precautions The laboratory temperature affects the experimental results and should be controlled at (23±2)℃. Only one person should be allowed to conduct experiments in every 20㎡ laboratory. Too many people will cause the laboratory temperature to rise, which will affect the experimental data. At the same time, the temperature control and experimental process should not be frequently entered and exited to reduce the impact of changes in the test environment on the experimental data.The sample should not have creases, pinholes, or gaps.It is forbidden to wipe the instrument housing with alcohol cleaners (such as isopropyl alcohol, anhydrous alcohol, alcohol), otherwise it will cause the housing to crack or scratch.It is recommended to clean the sealing grease remaining in the cavity before loading the sample, and then apply a layer of sealing grease to ensure that there is no leakage.   Maintenance The voltage of the power supply during operation must meet the value allowed by the equipment, otherwise a voltage regulator greater than 1/3 of the actual power should be set. The current allowable value of the power supply line should be greater than 1/3 of the actual current.The instrument must be well grounded when installed.Keep the instrument test environment temperature at 23℃±2℃ and the humidity at 50±10%.The instrument must be installed on a horizontal, solid, stable, and vibration-free table. There is no airflow interference and no strong electromagnetic interference.99.999% high-purity nitrogen must be used for experiments, otherwise the sensor will be damaged.When the gas interface on the back of the instrument is empty, it must be sealed with a blind plug, otherwise it will affect the performance of the gas filter.The cavity seal will age after long-term use and affect the sealing effect, and must be replaced in time.After each experiment, you need to wipe the cavity with pure cotton paper or a clean rag to avoid dirt.When the instrument is not in use, keep it clean and dry and cut off the power supply.If the instrument is not used for a long time, it is recommended to rinse it once a week for 8 hours, and place an aluminum film before rinsing.When cleaning the instrument on a daily basis, it is recommended to use a soft cloth dipped in water or a mild detergent to clean the outside of the instrument regularly. Do not allow dust to enter the test chamber, otherwise it may damage the internal circuit or sensor of the instrument, resulting in unstable readings or no readings.

Abstract Pet food is specialized in providing food for pets and small animals, and is a high-grade animal food between human food and traditional livestock and poultry feed. Its main nutrients are proteins and fats, which are easy to absorb moisture and agglomerate or be oxidized and decomposed by microorganisms under the action of certain temperature, oxygen and moisture, resulting in the loss of nutrients and even deterioration, so it is required that the barrier performance of the pet food packaging should be good. This paper utilizes GBPI's self-developed N530 2.0 Gas Transmission Rate Tester to test the oxygen transmission rate of dog food bags sent by customers, and introduces the testing instrument, testing principle, testing process, etc., which provides an effective solution for monitoring the oxygen barrier performance of pet food packaging bags. With the development of the economy and the improvement of people's living standards, more and more people have pets. People use pets as a support for their feelings and to meet our emotional needs, corresponding to the rapid development of the pet food industry, the market competition is gradually fierce, the importance of pet food packaging has gradually come to the fore. Cat food / dog food packaging bags selected plastic material should have a barrier, heat resistance, sealing, able to prevent food deterioration. General selection of multi-layer plastic composite, common materials include PET/AL/PE, PET/NY/PE, PET/MPET/PE, PET/AL/PET/PE, PET/NY/AL/PE, PET/NY/AL/RCPP, high-temperature dry distillation bags for wet food, soft canned food packaging. Like other foods, pet food has a shelf life. During the shelf life, pet food needs to ensure that no spoilage or loss of nutrients occurs. Pet food nutrients can meet the needs of pet growth, but also is a good natural medium for microbial growth. If the packaging material has poor barrier properties, the oxygen and moisture that passes through the packaging can lead to the growth of microorganisms. Under the action of microorganisms, the nutrients (proteins, fats, etc.) in the pet food will be decomposed, which not only affects the sensory of the pet food, but also loses the nutritional value of proteins, fats and other original substances. The growth of microorganisms is mainly due to three factors: temperature, oxygen, moisture, oxygen is the main external cause of rancidity, so the pet food packaging must have a good barrier performance to the outside world of oxygen, in order to effectively ensure the quality of pet food in the shelf period. This paper utilizes GBPI's self-developed N530 2.0 differential pressure gas permeability tester to test the oxygen barrier performance of dog food packaging bags sent by customers to provide technical references for relevant pet food package production and use of enterprises to select the oxygen barrier performance test equipment and test methods.   Test Principle: N530 2.0 Gas Transmission Rate Test...

Abstract: Peeling force is to evaluate the composite film peeling performance indicators, the size of the value reflects the composition of the composite film monolayer membrane composite fastness. Low peeling force of composite film materials, after making the contents of the bag packaging is prone to delamination phenomenon, resulting in composite film impact resistance, puncture resistance and other physical and mechanical properties and barrier properties decline, affecting the appearance and quality of the product. In this paper, we use the GBH-2 electronic tensile testing machine independently developed by Guangzhou Standard International to carry out the peeling test of composite film for pickles packaging, introduce the test standard, test equipment, test process, etc., and effectively evaluate the anti-interlayer peeling performance of composite film for pickles packaging. Pickled vegetables is a general term for a variety of vegetable products made from vegetables as the main raw materials and using different pickling techniques. According to the process and auxiliary materials, pickles can be divided into soy sauce, salt pickles, soy sauce pickles, sugar pickles, vinegar pickles, sweet and sour pickles, shrimp oil pickles, brine pickles, bad pickles and so on. Due to the unique aroma of sweet and crispy pickles, or salty and spicy pickles, and their nutritional value, they have won the favour of the masses and have become one of the most popular foodstuffs to accompany meals.   Bagging is a common packaging form of pickles, the bag material is mainly plastic composite film, aluminium composite film, etc., generally using vacuum packaging form to prevent pickles rancidity. In the actual use of the process, some pickles finished packaging will appear composite film delamination phenomenon. If the adhesive used in the composite film and the ink used in the external printing of the package is of poor quality and not resistant to high temperature or acid or alkali, it is easy to cause the composite film to reduce the composite fastness of each single layer of the film and the composite film is prone to delamination after high-temperature sterilisation or contact with the acid or alkali components in pickles. On the other hand, if the composite film using the adhesive coating amount is too low or too thick, or uneven coating, will also cause the composite film between the layers of film composite fastness is poor, easy to occur delamination. Once the phenomenon of delamination occurs, the bag composite film impact resistance, puncture resistance and other physical and mechanical properties will decline, resulting in easy rupture of the bag, leakage; at the same time will also affect the composite film on the outside world of oxygen barrier properties, resulting in an increase in the amount of oxygen through the packaging contents are prone to deterioration, flavour, and seriously affect the appearance of the product and product quality....
