Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of packaging film design simulation, and in particular to a packaging film design simulation analysis method based on simulation data. Background Art
[0002] In the packaging industry, packaging film is an important material for protecting goods, facilitating transportation and storage, and its performance is directly related to the quality and safety of the product. Traditional packaging design methods mostly rely on experimental testing and experience accumulation, which has problems such as long design cycle, high cost, and difficulty in comprehensively evaluating the performance of packaging film in various environments. Therefore, it is particularly important to develop a packaging film design simulation analysis method based on simulation data.
[0003] For example, the Chinese patent publication number CN102096731B discloses an expert system for designing modified atmosphere packaging for fruits and vegetables, including: an information input module, the information input module is connected to a microprocessor system, the microprocessor system is connected to a display; the information input module inputs the size parameters of the film bag; the microprocessor system calculates the volume of the film bag, and then determines the maximum inflation volume of the film bag; the information input module inputs the packaging weight and the initial gas volume; when the microprocessor system determines that the sum of the volume of the fruit and vegetable body and the initial gas volume is not greater than the maximum inflation volume, the packaging weight and the initial gas volume are determined. Due to the adoption of the above technical solution, the present invention overcomes the defects of large experimental workload, high time consumption, and high cost, and the user independently inputs known packaging parameters, simulates the packaging effect, judges the modified atmosphere packaging of fruits and vegetables, and determines the appropriate packaging weight and initial gas volume.
[0004] The above existing technologies still have the following problems: 1. In terms of moisture-proof performance evaluation, the analysis dimension is relatively single, and the moisture-proof performance of the moisture-proof packaging film is not comprehensively analyzed from the perspective of water vapor permeability and humidity distribution. The moisture-proof performance of the moisture-proof packaging film cannot be fully demonstrated, which reduces the accuracy of the moisture-proof performance evaluation.
[0005] 2. In the humidity distribution, only the abnormal distribution of humidity on both sides of the membrane is paid attention to, and the fluctuation of humidity on both sides of the membrane is not analyzed. It is impossible to accurately predict the probability and severity of the risk, and thus it is impossible to take effective countermeasures in time to reduce the risk.
[0006] 3. When there are problems with the moisture-proof performance of the moisture-proof packaging film, the thickness of the moisture-proof packaging film is not reset and the simulation operation is continued; when there are no problems with the moisture-proof performance of the moisture-proof packaging film, the moisture-proof performance of the moisture-proof packaging film in each simulated humidity is not simulated, and the applicable humidity range of the moisture-proof packaging film is not obtained, and it is impossible to ensure that the packaging film can effectively isolate moisture under specific humidity conditions, which causes the packaging to become damp and deteriorate, and the shelf life of the product cannot be extended, increasing the losses and waste caused by moisture. Summary of the invention
[0007] In view of this, in order to solve the problems raised in the above background technology, a packaging film design simulation analysis method based on simulation data is proposed.

[0010] S3. Determine whether there is a problem with moisture-proof performance of the target moisture-proof packaging film model in the initial simulation environment. If there is no problem, execute step S5; if there is a problem, execute step S4.
[0011] S4, resetting the packaging film thickness: resetting the thickness of the target moisture-proof packaging film model, and repeating steps S1 to S3.
[0012] S5. Simulation humidity transformation: keep the initial simulation temperature input in the target simulation software unchanged, extract the simulation loading results corresponding to each monitoring time point of the target moisture-proof packaging film model under each simulation humidity, and evaluate the moisture-proof performance index of the target moisture-proof packaging film model in each simulation humidity in the same way as the moisture-proof performance index of the target moisture-proof packaging film model in the initial simulation environment.
[0013] S6. Confirmation of applicable humidity range: Determine whether the moisture-proof performance of the target moisture-proof packaging film model in each simulated humidity meets the standard. If not, confirm the applicable humidity range corresponding to the target moisture-proof packaging film model and provide feedback.
[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention calculates the water vapor permeability anomaly index and the humidity anomaly index on both sides of the film of the target moisture-proof packaging film model in the initial simulation environment, thereby evaluating the moisture-proof performance of the target moisture-proof packaging film model in the initial simulation environment. The analysis dimensions are relatively rich, which can comprehensively demonstrate the moisture-proof performance of the moisture-proof packaging film and improve the accuracy of the moisture-proof performance evaluation.
[0015] (2) The present invention calculates the humidity fluctuation coefficient on both sides of the film and the humidity distribution anomaly index on both sides of the film of the target moisture-proof packaging film model in the initial simulation environment, thereby evaluating the humidity anomaly on both sides of the film of the target moisture-proof packaging film model in the initial simulation environment, helping to accurately predict the probability and severity of risk occurrence, so that effective countermeasures can be taken in time to reduce the risk.
[0016] (3) When there is a problem with the moisture-proof performance of the moisture-proof packaging film, the present invention resets the thickness of the moisture-proof packaging film and continues the simulation operation. When there is no problem with the moisture-proof performance of the moisture-proof packaging film, the moisture-proof performance of the moisture-proof packaging film in each simulated humidity is simulated to obtain the applicable humidity range of the moisture-proof packaging film. This can ensure that the packaging film can effectively isolate moisture under specific humidity conditions to prevent the packaged objects from being affected by moisture and deteriorating. By controlling the humidity in the package, the shelf life of the product can be extended and the loss and waste caused by moisture can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] It should be noted that the humidity distribution diagram of both sides of the film of the target moisture-proof packaging film model in the initial simulation environment is drawn using the built-in drawing function in the target simulation software.
[0035] In a specific embodiment of the present invention, the specific process of calculating the abnormal index of humidity distribution on both sides of the film of the target moisture-proof packaging film model under the initial simulation environment is as follows: D1. The humidity corresponding to each humidity distribution area is located from the humidity distribution diagram on both sides of the film of the target moisture-proof packaging film model under the initial simulation environment, and the humidity is compared with the humidity of the humidity distribution area of the set reference. If the humidity corresponding to a humidity distribution area is greater than the humidity of the humidity distribution area of the set reference, the humidity distribution area is recorded as an abnormal area, and the number of abnormal areas on both sides of the film of the target moisture-proof packaging film model under the initial simulation environment is counted and recorded as .

[0039] In a specific embodiment of the present invention, The setting value of is 0.5. The setting value of is 0.5. Abnormal humidity fluctuation may indicate that the packaging film lacks sufficient stability in dealing with changes in the external environment. For humidity-sensitive products (such as electronic products, medicines, and foods), drastic fluctuations in humidity may cause the product to become damp, moldy, or have performance degradation. Abnormal humidity distribution may indicate that the packaging film has problems in isolating external moisture or maintaining internal humidity uniformity. In practical applications, abnormal humidity fluctuations and abnormal humidity distribution on both sides of the film are often not isolated problems, but are interrelated. Therefore, comprehensive consideration is required when evaluating the humidity anomaly index of the packaging film model in the initial simulation environment.

[0042] In a specific embodiment of the present invention, The setting value of is 0.5. The set value is 0.5. Water vapor permeability is a direct indicator to measure the moisture-proof performance of packaging films. It reflects the barrier ability of packaging films to water vapor. High water vapor permeability means that the packaging film is difficult to effectively isolate external moisture, which may cause the humidity inside the package to rise, thereby affecting product quality. The humidity anomaly index on both sides of the film not only considers the barrier performance of the packaging film itself, but also pays attention to the changes in humidity inside the package. This helps to comprehensively evaluate the moisture-proof effect of the packaging film in actual use, including its adaptability and stability to changes in the external environment. When actually calculating the moisture-proof performance index, it is usually necessary to comprehensively consider the water vapor permeability anomaly index and the humidity anomaly index on both sides of the film.
