Description

Technical Field

[0001] The present application relates to the technical field of packaging detection, and in particular to a packaging accelerated deterioration test method. Background Art

[0002] In today's transportation field, especially in the process of transporting pole rolls, there is a key technical challenge, that is, how to accurately predict the life of pole rolls. The life here refers to the duration of time that the pole roll can maintain its performance unaffected during transportation, such as the life of sea transportation. As an extremely important industrial material, the prediction of the life of pole rolls during transportation is of great significance to ensure the stability and reliability of the entire supply chain.

[0003] During the transportation of pole rolls, an indirect method is usually used to predict their marine transportation life, that is, to predict by calculating the water seepage of the pole roll packaging. This method is based on the assumption that the water seepage of the packaging can reflect the environmental impact that the pole roll may suffer during transportation to a certain extent, thereby indirectly inferring its transportation life.

[0004] However, the transportation process often takes a long time, which requires long-term environmental simulation prediction to ensure that the performance of the packaging can meet the standards. Such simulation prediction usually requires complex calculations and a large amount of data support to ensure the accuracy of the prediction results. Summary of the invention

[0005] The present application provides a packaging accelerated deterioration test method, which can effectively simulate various environmental conditions that packaging materials may encounter during actual use, and equivalently shorten the test time, thereby evaluating its aging and deterioration in a shorter time.

[0006] In a first aspect, the present application provides a packaging accelerated deterioration test method for equivalently shortening the deterioration time of the packaging, the method comprising the following steps:

[0007] Based on the selected materials, determine the target temperature, target humidity, target transportation days and target moisture content;

[0008] Taking the target moisture content as a quantitative value, the equivalent test temperature, test humidity and test transportation days are calculated; wherein the test transportation days are less than the target transportation days;

[0009] Setting at least one of the test temperature and the test humidity as a variable, and determining the value of the other parameter by a corresponding formula or a limited number of tests;

[0010] The test transportation days are set to test days that are less than the preset days, and the corresponding test temperature and test humidity are calculated based on the test days.

[0011] The above method demonstrates a test method for accelerating the aging process of packaging materials, aiming to equivalently shorten the deterioration time of packaging materials by simulating environmental conditions.

[0012] Through the above steps, various environmental conditions that packaging materials may encounter during actual use can be effectively simulated, and the test time can be shortened equivalently, so that their aging and deterioration can be evaluated in a shorter period of time, providing a scientific basis for product packaging design and material selection.

[0013] In some examples, the test humidity is set to a quantitative value, the corresponding test temperature is t and the test transportation days is T1, and T1 = At B , A and B are constants corresponding to packaging related materials, and the values ​​of A and B corresponding to different packaging are different;

[0014] Among them, B<0, T1 is negatively correlated with t, and the higher the test temperature, the lower the test transportation days.

[0015] Based on the above example, the test humidity can be set to a fixed value, and then the corresponding test temperature and test transportation days are determined according to this humidity value. Specifically, the test temperature is set to t, and the test transportation days are set to T1. According to this setting, T1 = At B Such a formula, where A and B are constants related to the packaging material. Different packaging materials will have different A and B values, which are predetermined based on the characteristics of the material. In this formula, the value of B is less than 0, which means that there is a negative correlation between the test transportation days T1 and the test humidity t. That is, when the test temperature t is higher, the required test transportation days T1 is shorter.

[0016] By applying the above formula, the specific values ​​of other relevant parameters except the test temperature can be determined. This method can effectively simulate various environmental conditions that packaging materials may encounter during actual use, and shorten the test time equivalently, so as to evaluate their aging and deterioration in a shorter time. In this way, the performance of packaging materials in different environments can be quickly understood, and the selection and use of materials can be optimized to ensure the safety and quality of products.

[0017] In some examples, the test temperature is set to a certain value, the corresponding test humidity is W and the test transportation days is T2, and T2 = AW B , A and B are constants corresponding to packaging related materials, and the values ​​of A and B corresponding to different packaging are different;

[0018] Among them, B<0, T2 is negatively correlated with W, and the higher the test humidity is, the lower the test transportation days are.

[0019] Based on the above example, the test temperature can be set as a quantitative value to facilitate more accurate testing. At the same time, the corresponding test humidity needs to be set as W, and the test transportation days need to be set as T2. According to a specific formula, the value of T2 can be calculated as AW B , where A and B are constants related to the packaging material. The values ​​of these constants vary depending on the packaging material. It is worth noting that the value of B is less than 0, which means that there is a negative correlation between T2 and W. In other words, when the value of the test humidity W is higher, the value of the test transportation days T2 will decrease accordingly.

[0020] By applying the above formula, the specific values ​​of other relevant parameters except the test temperature can be determined. This method can effectively simulate various environmental conditions that packaging materials may encounter during actual use. In this way, the aging and deterioration of packaging materials can be evaluated in a shorter period of time, thus providing a scientific basis for product packaging design and material selection. In this way, it can be ensured that the packaging materials can achieve the expected protection effect during actual use, extend the shelf life of the product, and improve the market competitiveness of the product.

[0021] In some examples, the test humidity and the test temperature are both set as variables, and the value of the test transportation days is reduced by increasing the value of at least one of the test humidity and the test temperature.

[0022] Based on the above example, both the test humidity and the test temperature can be set as variable variables. By increasing the value of at least one of the two variables, it can be observed that the value of the test transportation days will be reduced accordingly. For example, if the value of the test humidity is increased, or the value of the test temperature is increased, or the values ​​of these two parameters are increased at the same time, the value of the test transportation days will be reduced accordingly. This phenomenon shows that the increase of the test humidity and the test temperature will have a direct impact on the test transportation days, resulting in a reduction in the test transportation days.

[0023] In some examples, after the test temperature and the test humidity are determined, multiple preliminary tests are performed to verify the accuracy of the selected parameters.

[0024] Based on the above example, in order to ensure the accuracy and reliability of the test, after determining the temperature and humidity parameters of the test, multiple pre-tests are carried out to verify the rationality of these selected parameters. The main purpose of these pre-tests is to ensure that the selected test conditions can truly reflect the various environmental factors that may be encountered during actual transportation.

[0025] Specifically, the pre-test process involves placing the packaged samples under pre-set test temperature and humidity conditions. Observe and record in detail the physical and chemical changes of the samples at different time points. In this way, it can be evaluated whether the test conditions can effectively simulate the temperature and humidity changes that may be encountered during actual transportation, thereby ensuring that the samples can maintain their stability and effectiveness during actual transportation.

[0026] In some examples, the test temperature, the test humidity, the preset number of days and the qualified moisture content corresponding to the test target are determined by the pre-test;

[0027] Based on the test temperature, the test humidity and the preset number of days, a formal accelerated deterioration test is performed by comparing the qualified moisture content.

[0028] Based on the above example, preliminary tests are conducted to determine the equivalent test temperature, test humidity, preset number of days, and qualified moisture content corresponding to the test objectives. The purpose of these preliminary tests is to better set the parameters of the formal accelerated deterioration test. Based on the data obtained from these preliminary tests, researchers can set a suitable test temperature, test humidity, and preset number of days, and then compare the set qualified moisture content on this basis to conduct a formal accelerated deterioration test.

[0029] In some examples, performing a performance test on the qualified packages that pass the accelerated deterioration test;

[0030] Performance tests include compressive strength test, drop test, vibration test and sealing performance test.

[0031] Based on the above examples, a series of performance tests can be conducted on the packages that have passed the accelerated deterioration test. These performance tests mainly include compressive strength test, drop test, vibration test and sealing performance test.

[0032] Through these comprehensive performance tests, the comprehensive performance of packaging under harsh conditions can be fully evaluated to ensure its reliability during actual transportation. These tests can not only help discover potential problems in packaging design, but also provide strong data support for improving packaging materials and structures, ultimately achieving the goal of improving packaging quality and protection effects.

[0033] In some examples, packaging design is optimized based on test results, and the optimization methods include:

[0034] Adjust packaging materials, structures or production processes;

[0035] Repeat the accelerated deterioration test until the predetermined performance requirements are met.

[0036] Based on the above examples, the product packaging design can be carefully optimized according to the test results. This optimization method usually includes the following aspects:

[0037] The materials used for packaging can be adjusted by choosing more durable or more protective materials to ensure that the product is better protected during transportation and storage.

[0038] The structure of the packaging can be improved, such as adding cushioning materials, improving the sealing method, or adjusting the packaging size to increase its impact and moisture resistance.

[0039] The production process can also be optimized, such as improving the degree of automation in the packaging process, increasing production efficiency or reducing material waste, thereby improving the overall quality and performance of the packaging.

[0040] In order to verify the optimization effect, the accelerated deterioration test can be repeated. This test accelerates the aging process of the packaging material by simulating more severe environmental conditions, such as high temperature, high humidity, vibration, etc., so as to evaluate its performance in a shorter time. By repeating this test process many times, the packaging design can be continuously adjusted and improved until its performance under accelerated conditions meets the predetermined standards and requirements.

[0041] In some examples, samples of the optimized packaging are subjected to accelerated deterioration tests multiple times to verify the effectiveness of the optimized packaging performance.

[0042] Based on the above examples, the optimized packaging samples can be subjected to multiple accelerated aging tests. The purpose of these tests is to further verify the performance of the improved packaging in harsh environments and ensure that it can withstand various adverse factors during long-term transportation and storage.

[0043] In some examples, the test methods are applied to different types of packaging materials and structures to evaluate the adaptability and stability of different packages under the same environmental conditions.

[0044] Based on the above examples, the test method can be applied to various types of packaging materials and structures to evaluate the adaptability and stability of these packages under the same environmental conditions. These environmental conditions may include changes in factors such as temperature, humidity, and pressure. Through this comprehensive test, we can fully understand the performance of different packaging materials and structures in actual applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0066] To solve the above technical problems, please refer to Figure 1-Figure 2 As shown, the first aspect of the present application proposes a packaging accelerated deterioration test method, which can effectively simulate various environmental conditions that packaging materials may encounter during actual use, and shorten the test time equivalently, thereby evaluating its aging and deterioration in a shorter time.

[0067] In some examples, a package accelerated deterioration test method is shown, which is used to equivalently shorten the deterioration time of the package, and the steps of the method include:

[0068] Step S100: Based on the selected material, determine the target temperature, target humidity, target transportation days and target moisture content; the target transportation days in this application can be sea transportation days or land transportation days, which can be selected according to actual needs.

[0069] This step can clarify and determine the target temperature, target humidity, target transportation days, and target moisture content. These parameters are key factors in simulating the aging process and need to be set according to actual application scenarios and requirements.

[0070] Step S200: taking the target moisture content as a quantitative value, calculating the equivalent test temperature, test humidity and test transportation days; wherein the test transportation days are less than the target transportation days;

[0071] This step uses the target moisture content as a quantitative benchmark, and uses scientific calculations and related formulas to deduce the equivalent test temperature, test humidity, and test transportation days. In this process, the test transportation days should be less than the actual target transportation days to achieve the purpose of accelerated aging.

[0072] Step S300: setting at least one of the test temperature and the test humidity as a variable, and determining the value of the other parameter by a corresponding formula or a limited number of tests;

[0073] This step sets at least one of the test temperature and test humidity as a variable. Through a series of tests or by applying corresponding formulas, the specific values ​​of other related parameters are determined. This process requires repeated verification to ensure the accuracy and reliability of the test results.

[0074] Step S400: setting the test transportation days to a test day number that is less than a preset number of days, and calculating the corresponding test temperature and test humidity based on the test days.

[0075] This step sets the test transportation days to a test day number that is less than the preset days. Based on the test days, the corresponding test temperature and test humidity are further calculated. In this way, by adjusting these environmental parameters, the deterioration of packaging materials during long-term transportation and storage can be simulated in a shorter time.

[0076] The above method demonstrates a test method for accelerating the aging process of packaging materials, aiming to equivalently shorten the deterioration time of packaging materials by simulating environmental conditions.

[0077] Through the above steps, various environmental conditions that packaging materials may encounter during actual use can be effectively simulated, and the test time can be shortened equivalently, so that their aging and deterioration can be evaluated in a shorter period of time, providing a scientific basis for product packaging design and material selection.

[0078] In some examples, the test temperature is set to a certain value, the corresponding test humidity is W and the test transportation days is T2, and T2 = AW B , A and B are constants corresponding to packaging related materials, and the values ​​of A and B corresponding to different packaging are different;

[0079] Among them, B<0, T2 is negatively correlated with W, and the higher the test humidity is, the lower the test transportation days are.

[0080] Based on the above example, the test temperature can be set as a quantitative value to facilitate more accurate testing. At the same time, the corresponding test humidity needs to be set as W, and the test transportation days need to be set as T2. According to a specific formula, the value of T2 can be calculated as AW B , where A and B are constants related to the packaging material. The values ​​of these constants vary depending on the packaging material. It is worth noting that the value of B is less than 0, which means that there is a negative correlation between T2 and W. In other words, when the value of the test humidity W is higher, the value of the test transportation days T2 will decrease accordingly.

[0081] By applying the above formula, the specific values ​​of other relevant parameters except the test temperature can be determined. This method can effectively simulate various environmental conditions that packaging materials may encounter during actual use. In this way, the aging and deterioration of packaging materials can be evaluated in a shorter period of time, thus providing a scientific basis for product packaging design and material selection. In this way, it can be ensured that the packaging materials can achieve the expected protection effect during actual use, extend the shelf life of the product, and improve the market competitiveness of the product.

[0082] After setting the test temperature to a quantitative value, the test time is shortened by changing the test humidity. Nine embodiments are described in detail using three materials and three target data for each material.

[0083] Embodiment 1

[0084] Reference Figure 2 As shown in the figure, the horizontal axis (x-axis) is humidity, and the vertical axis (y-axis) is time. The corresponding formula can be based on the x-axis and y-axis using y=Ax B Indicates that R in the figure 2 is the correlation, which can also be considered as the acceleration deviation, R 2 The closer the value is to 1, the more accurate the accelerated deterioration test is. Figures 3 to 10 ) have similar meanings and will not be described in detail later.

[0085] First target data based on the first material:

[0086]

[0087]

[0088] Among them, based on the selection of the first material, the first target data is determined, and the target data may specifically include: target humidity is 60%, target temperature is 45°C, target transportation days is 60 days, and target moisture content is increased by about 74. The target moisture content may be the water permeability of the package. The package that meets the above target data is a qualified package, and the value of the increase in the target moisture content may have a certain error.

[0089] Test data using humidity as a variable to accelerate deterioration and shorten test time:

[0090] humidity temperature time Increased moisture 60％ 60 8 69 70％ 60 6 84 80％ 60 4 79 90％ 60 3 81

[0091] It can be seen from the above test data that when the test temperature is set to 60°C and the humidity is used as a variable, in the above four groups of tests, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 60%, the test time is shortened to 8 days; when the humidity is 70%, the test time is shortened to 6 days; when the humidity is 80%, the test time is shortened to 4 days; when the humidity is 90%, the test time is shortened to 3 days.

[0092] That is to say, the increase in humidity can accelerate the deterioration of the package, thereby achieving the effect of shortening the test time. For example, when the humidity reaches 90%, the test time will be shortened to three days, so that the package test can be completed in about three days, achieving the beneficial effect of accelerating the deterioration and quickly testing the qualified rate of the package. The third group of data with the smallest error in the increase of the target moisture content in the above test data with a humidity of 80% is the data. At this time, the number of test days is 4 days. When higher test accuracy is required, the third test data can be used for formal testing.

[0093] When the humidity is a variable in the present application, it is not limited to the above integer humidity variable, and the humidity can also be adjusted to a humidity range of 65%, 78.8% and other numerical values ​​according to needs. The above four sets of data are only exemplary. Figure 2 , the correlation in this embodiment is 0.991, and the test data has certain validity.

[0094] Embodiment 2

[0095] Reference Figure 3 As shown in the figure, the horizontal axis (x-axis) is humidity, and the vertical axis (y-axis) is time. The second target data based on the first material is:

[0096] humidity temperature time Increased moisture 60％ 60 60 292

[0097] Among them, based on the selection of the first material, the second target data is determined, and the target data may specifically include: target humidity is 60%, target temperature is 60°C, target transportation days is 60 days, and the target moisture content increases by about 292. The packaging that meets the above target data is qualified packaging, and the value of the target moisture content increase may have a certain error.

[0098] Test data using humidity as a variable to accelerate deterioration and shorten test time:

[0099]

[0100]

[0101] It can be seen from the above test data that the test temperature is set to 60°C and the humidity is used as a variable. In the above four groups of tests, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 60%, the test time is maintained at 60 days (the first group of data is the same as the target data); when the humidity is 70%, the test time is shortened to 40 days; when the humidity is 80%, the test time is shortened to 25 days; when the humidity is 90%, the test time is shortened to 20 days.

[0102] In other words, the increase in humidity can accelerate the deterioration of the package, thereby shortening the test time. For example, when the humidity reaches 90%, the test time will be shortened to 20 days, so that the package test can be completed in about 20 days, achieving the beneficial effect of accelerating the deterioration and quickly testing the qualified rate of the package. Among the above test data, the fourth group of data with a humidity of 90% has the smallest error in the increase of the target moisture content and the least number of test days. At this time, the number of test days is 20 days, which is reduced to one-third of the original number of test days.

[0103] When the humidity is a variable in the present application, it is not limited to the above integer humidity variable, and the humidity can also be adjusted to a humidity range of 65%, 78.8% and other numerical values ​​according to needs. The above four sets of data are only exemplary. Figure 3 , the correlation in this embodiment is 0.9904, and the test data has certain validity.

[0104] Embodiment 3

[0105] Reference Figure 4 As shown in the figure, the horizontal axis (x-axis) is humidity, and the vertical axis (y-axis) is time, based on the third target data of the first material:

[0106] humidity temperature time Increased moisture 80％ 60 60 603

[0107] Among them, based on the selection of the first material, the third target data is determined, and the target data may specifically include: target humidity is 80%, target temperature is 60°C, target transportation days is 60 days, and the target moisture content increases by about 603. The packaging that meets the above target data is qualified packaging, and the value of the target moisture content increase may have a certain error.

[0108] Test data using humidity as a variable to accelerate deterioration and shorten test time:

[0109] humidity temperature time Increased moisture 80％ 60 60 603 90％ 60 40 578

[0110] It can be seen from the above test data that the test temperature is set to 60°C and the humidity is used as a variable. In the above test, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 80%, the test time is maintained to 60 days (the first set of data is the same as the target data); when the humidity is 90%, the test time is shortened to 40 days.

[0111] When the humidity reaches 90%, the test time will be shortened to 40 days, so that the packaging test can be completed in about 40 days, achieving the beneficial effect of accelerating the deterioration and quickly testing the packaging qualification rate.

[0112] When the humidity is a variable in the present application, it is not limited to the integer humidity variable. The humidity can also be adjusted to a humidity range of 85%, 88.8% and other numerical values ​​according to needs. The above two sets of data are only exemplary. Figure 4 , the correlation in this embodiment is 1, and the test data has certain validity.

[0113] Embodiment 4:

[0114] Reference Figure 5 As shown in the figure, the horizontal axis (x-axis) is humidity, and the vertical axis (y-axis) is time, based on the first target data of the second material:

[0115] humidity temperature time Increased moisture 60％ 45 60 68

[0116] Among them, based on the selection of the second material, the first target data is determined, and the target data may specifically include: target humidity is 60%, target temperature is 45°C, target transportation days is 60 days, and the target moisture content increases by about 68. The packaging that meets the above target data is qualified packaging, and the value of the target moisture content increase may have a certain error.

[0117] Test data using humidity as a variable to accelerate deterioration and shorten test time:

[0118] humidity temperature time Increased moisture 60％ 60 10 73 70％ 60 8 71 80％ 60 6 67 90％ 60 4 65

[0119] It can be seen from the above test data that when the test temperature is set to 60°C and the humidity is used as a variable, in the above four groups of tests, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 60%, the test time is shortened to 10 days; when the humidity is 70%, the test time is shortened to 8 days; when the humidity is 80%, the test time is shortened to 6 days; when the humidity is 90%, the test time is shortened to 4 days.

[0120] When the humidity reaches 90%, the test time will be shortened to 4 days, so that the packaging test can be completed in about 4 days, achieving the beneficial effect of accelerating the deterioration and quickly testing the packaging qualification rate.

[0121] When the humidity is a variable in the present application, it is not limited to the above integer humidity variable, and the humidity can also be adjusted to a humidity range of 75%, 88.8% and other numerical values ​​according to needs. The above data is only an exemplary description. Figure 5 , the correlation in this embodiment is 0.9628, and the test data has certain validity.

[0122] Embodiment 5

[0123] Reference Figure 6 As shown, the horizontal axis (x-axis) in the figure is humidity, and the vertical axis (y-axis) is time. The second target data based on the second material is:

[0124] humidity temperature time Increased moisture 60％ 60 60 237

[0125] Among them, based on the selection of the second material, the second target data is determined, and the target data may specifically include: target humidity is 60%, target temperature is 60°C, target transportation days is 60 days, and the target moisture content increases by about 237. The packaging that meets the above target data is qualified packaging, and the value of the target moisture content increase may have a certain error.

[0126] Test data using humidity as a variable to accelerate deterioration and shorten test time:

[0127]

[0128]

[0129] It can be seen from the above test data that when the test temperature is set to 60°C and the humidity is used as a variable, in the above four groups of tests, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 60%, the test time is maintained at 60 days; when the humidity is 70%, the test time is shortened to 40 days; when the humidity is 80%, the test time is shortened to 25 days; when the humidity is 90%, the test time is shortened to 20 days.

[0164] humidity temperature time Increased moisture 80％ 60 60 1156 90％ 60 40 1033

[0165] It can be seen from the above test data that the test temperature is set to 60°C and the humidity is used as a variable. In the above test, as the humidity increases, the number of days to reach the error range of the target moisture content is shortened. When the humidity is 80%, the test time is maintained at 60 days (the first set of data is the same as the target data); when the humidity is 90%, the test time is shortened to 40 days.

[0166] When the humidity reaches 90%, the test time will be shortened to 40 days, so that the packaging test can be completed in about 40 days, achieving the beneficial effect of accelerating the deterioration and quickly testing the packaging qualification rate.

[0167] When the humidity is a variable in the present application, it is not limited to the integer humidity variable. The humidity can also be adjusted to a humidity range of 85%, 88.8% and other numerical values ​​according to needs. The above two sets of data are only exemplary. Fig.10 , the correlation in this embodiment is 1, and the test data has certain validity.

[0168] In some examples, the test humidity is set to a quantitative value, the corresponding test temperature is t and the test transportation days is T1, and T1 = At B , A and B are constants corresponding to packaging related materials, and the values ​​of A and B corresponding to different packaging are different;

[0169] Among them, B<0, T1 is negatively correlated with t, and the higher the test temperature, the lower the test transportation days.

[0170] Based on the above example, the test humidity can be set to a fixed value, and then the corresponding test temperature and test transportation days are determined according to this humidity value. Specifically, the test temperature is set to t, and the test transportation days are set to T1. According to this setting, T1 = At B Such a formula, where A and B are constants related to the packaging material. Different packaging materials will have different A and B values, which are predetermined based on the characteristics of the material. In this formula, the value of B is less than 0, which means that there is a negative correlation between the test transportation days T1 and the test humidity t. That is, when the test temperature t is higher, the required test transportation days T1 is shorter.

[0171] By applying the above formula, the specific values ​​of other relevant parameters except the test temperature can be determined. This method can effectively simulate various environmental conditions that packaging materials may encounter during actual use, and shorten the test time equivalently, so as to evaluate their aging and deterioration in a shorter time. In this way, the performance of packaging materials in different environments can be quickly understood, and the selection and use of materials can be optimized to ensure the safety and quality of products.

[0172] After setting the test humidity to quantitative, the test time is shortened by changing the test temperature. Nine embodiments are described in detail using three materials and three target data for each material.

[0251] Test data using temperature as a variable to accelerate deterioration and shorten test time:

[0252] humidity temperature time Increased moisture 60％ 70 30 1089 60％ 80 8 1176 60％ 90 2 1095

[0253] It can be seen from the above test data that the test humidity is set to 60% and the temperature is used as a variable. In the above four groups of tests, as the temperature increases, the number of days to reach the error range of the target moisture content is shortened. When the temperature is 70°C, the test time is shortened to 30 days; when the temperature is 80°C, the test time is shortened to 8 days; when the temperature is 90°C, the test time is shortened to 2 days.

[0254] That is to say, the increase in temperature can accelerate the deterioration of the package, thereby shortening the test time. For example, when the temperature reaches 90°C, the test time will be shortened to 2 days, so that the package test can be completed in about 2 days, achieving the beneficial effect of accelerating the deterioration and quickly testing the package qualification rate.

[0255] When the temperature is a variable in the present application, it is not limited to the temperature variable of the integer, and the temperature can also be adjusted to a temperature range of 75°C, 85.5°C, etc. as needed. The above four sets of data are only exemplary. Combined with the accompanying drawings, the correlation in this embodiment is 0.9975, and the test data has certain validity.

[0256] In some examples, the test humidity and the test temperature are both set as variables, and the value of the test transportation days is reduced by increasing the value of at least one of the test humidity and the test temperature.

[0257] Based on the above example, both the test humidity and the test temperature can be set as variable variables. By increasing the value of at least one of the two variables, it can be observed that the value of the test transportation days will be reduced accordingly. For example, if the value of the test humidity is increased, or the value of the test temperature is increased, or the values ​​of these two parameters are increased at the same time, the value of the test transportation days will be reduced accordingly. This phenomenon shows that the increase of the test humidity and the test temperature will have a direct impact on the test transportation days, resulting in a reduction in the test transportation days.

[0258] In some examples, after the test temperature and the test humidity are determined, multiple preliminary tests are performed to verify the accuracy of the selected parameters.

[0259] Based on the above example, in order to ensure the accuracy and reliability of the test, after determining the temperature and humidity parameters of the test, multiple pre-tests are carried out to verify the rationality of these selected parameters. The main purpose of these pre-tests is to ensure that the selected test conditions can truly reflect the various environmental factors that may be encountered during actual transportation.

[0260] Specifically, the pre-test process involves placing the packaged samples under pre-set test temperature and humidity conditions. Observe and record in detail the physical and chemical changes of the samples at different time points. In this way, it can be evaluated whether the test conditions can effectively simulate the temperature and humidity changes that may be encountered during actual transportation, thereby ensuring that the samples can maintain their stability and effectiveness during actual transportation.

[0261] By repeating such preliminary tests many times, the test parameters can be further optimized and adjusted to ensure that the final test results are highly representative and accurate. Such preliminary tests not only help improve the scientificity and rigor of the test, but also provide important reference for subsequent actual transportation and storage.

[0262] In some examples, the test temperature, the test humidity, the preset number of days and the qualified moisture content corresponding to the test target are determined by the pre-test;

[0263] Based on the test temperature, the test humidity and the preset number of days, a formal accelerated deterioration test is performed by comparing the qualified moisture content.

[0264] Based on the above example, preliminary tests are conducted to determine the equivalent test temperature, test humidity, preset number of days, and qualified moisture content corresponding to the test objectives. The purpose of these preliminary tests is to better set the parameters of the formal accelerated deterioration test. Based on the data obtained from these preliminary tests, researchers can set a suitable test temperature, test humidity, and preset number of days, and then compare the set qualified moisture content on this basis to conduct a formal accelerated deterioration test.

[0265] Formal accelerated deterioration testing involves the following steps:

[0266] A certain number of packaged samples are selected and placed under pre-set test temperature and humidity conditions for a preset number of days.

[0267] After these treatments, the samples are subjected to a battery of performance tests to evaluate the deterioration and protective properties of the packaging under these accelerated conditions.

[0268] Through these performance tests, we can understand whether the protective performance of the packaging material can meet the requirements under the environmental conditions that it may encounter during actual use, thereby providing a scientific basis for product packaging design and material selection.

[0269] In some examples, performing a performance test on the qualified packages that pass the accelerated deterioration test;

[0270] Performance tests include compressive strength test, drop test, vibration test and sealing performance test.

[0271] Based on the above examples, a series of performance tests can be conducted on the packages that have passed the accelerated deterioration test. These performance tests mainly include compressive strength test, drop test, vibration test and sealing performance test.

[0272] The compressive strength test is to examine the packaging's ability to withstand external pressure and ensure that it can withstand pressure from all directions without deformation or damage during actual transportation.

[0273] The drop test simulates the possible drop of the package during transportation. By dropping from different heights and angles, the integrity and protection capabilities of the package after impact are evaluated.

[0274] Vibration testing simulates the continuous vibration that may be encountered during transportation to verify the stability and protection effect of packaging under long-term vibration.

[0275] The sealing performance test focuses on the sealing of the packaging to ensure that it can effectively prevent the intrusion of external factors such as moisture and dust during transportation, keeping the internal items intact.

[0276] Through these comprehensive performance tests, the comprehensive performance of packaging under harsh conditions can be fully evaluated to ensure its reliability during actual transportation. These tests can not only help discover potential problems in packaging design, but also provide strong data support for improving packaging materials and structures, ultimately achieving the goal of improving packaging quality and protection effects.

[0277] In some examples, packaging design is optimized based on test results, and the optimization methods include:

[0278] Adjust packaging materials, structures or production processes;

[0279] Repeat the accelerated deterioration test until the predetermined performance requirements are met.

[0280] Based on the above examples, the product packaging design can be carefully optimized according to the test results. This optimization method usually includes the following aspects:

[0281] The materials used for packaging can be adjusted by choosing more durable or more protective materials to ensure that the product is better protected during transportation and storage.

[0282] The structure of the packaging can be improved, such as adding cushioning materials, improving the sealing method, or adjusting the packaging size to increase its impact and moisture resistance.

[0283] The production process can also be optimized, such as improving the degree of automation in the packaging process, increasing production efficiency or reducing material waste, thereby improving the overall quality and performance of the packaging.

[0284] In order to verify the optimization effect, the accelerated deterioration test can be repeated. This test accelerates the aging process of the packaging material by simulating more severe environmental conditions, such as high temperature, high humidity, vibration, etc., so as to evaluate its performance in a shorter time. By repeating this test process many times, the packaging design can be continuously adjusted and improved until its performance under accelerated conditions meets the predetermined standards and requirements.

[0285] If the test results show that the performance of the package under accelerated conditions does not meet the expected standards, then it is necessary to review and adjust the materials, structures or production processes used in the packaging. In this way, the root cause of the problem can be gradually found and targeted improvements can be made. Subsequently, the accelerated deterioration test can be carried out again to verify the effectiveness of the improvement measures. This process may be repeated many times until the performance of the package under accelerated conditions fully meets the predetermined requirements, ensuring its reliability and safety in actual use.

[0286] In some examples, samples of the optimized packaging are subjected to accelerated deterioration tests multiple times to verify the effectiveness of the optimized packaging performance.

[0287] Based on the above examples, the optimized packaging samples can be subjected to multiple accelerated aging tests. The purpose of these tests is to further verify the performance of the improved packaging in harsh environments and ensure that it can withstand various adverse factors during long-term transportation and storage.

[0288] By conducting a detailed comparative analysis of the test data before and after optimization, we can more accurately evaluate the specific improvement effect of the improvement measures on packaging performance. This evaluation includes not only the inspection of the durability and protection ability of the packaging material, but also the inspection of the overall structural stability of the packaging. Through these comprehensive tests, we can ensure that the final selected packaging design has a high degree of reliability and safety in actual application, thereby providing more comprehensive protection for the product.

[0289] In some examples, the test methods are applied to different types of packaging materials and structures to evaluate the adaptability and stability of different packages under the same environmental conditions.

[0290] Based on the above examples, the test method can be applied to various types of packaging materials and structures to evaluate the adaptability and stability of these packages under the same environmental conditions. These environmental conditions may include changes in factors such as temperature, humidity, and pressure. Through this comprehensive test, we can fully understand the performance of different packaging materials and structures in actual applications.

[0291] Through this method, the most suitable packaging solution can be selected for products of different types and needs. This not only ensures the safety and integrity of the product during transportation, but also improves the market competitiveness of the product. Selecting the most suitable packaging solution can reduce the damage rate during transportation, reduce logistics costs, and also improve consumer satisfaction. Therefore, this test method has important practical application value in packaging design and optimization.
