技术领域Technical Field
本发明涉及包装膜设计仿真技术领域，具体而言，涉及一种基于模拟数据的包装膜设计仿真分析方法。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.
背景技术Background Art
在包装行业中，包装膜作为保护商品、方便运输和存储的重要材料，其性能直接关系到产品的质量和安全性。传统包装设计方法多依赖于实验测试和经验积累，存在设计周期长、成本高、难以全面评估包装膜在各种环境下的性能等问题。因此，开发一种基于模拟数据的包装膜设计仿真分析方法显得尤为重要。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.
如中国专利公开号为CN102096731B的专利公开了果蔬气调包装设计专家系统，包括：信息输入模块，信息输入模块连接微型处理器系统，微型处理器系统连接显示器；信息输入模块输入薄膜袋的尺寸参数；微型处理器系统计算薄膜袋的容积，进而确定薄膜袋的最大充气体积；信息输入模块输入包装重量和初始气体体积；微型处理器系统判断出果蔬主体的体积与初始气体体积之和不大于最大充气体积时，确定包装重量和初始气体体积。由于采用上述技术方案，本发明本克服了实验工作量大、耗时多、费用大的缺陷，通过用户自主输入已知包装参数，模拟包装效果，对果蔬气调包装进行判断，确定适合的包装重量和初始气体体积。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.
以上现有技术中还存在以下问题：1、在防潮性能评估层面，分析维度较为单一，未同时从水蒸气透过情况和湿度分布情况出发对防潮包装膜的防潮性能进行综合分析，无法全面地展示防潮包装膜的防潮性能，降低了防潮性能评估的准确性。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.
2、在湿度分布情况中，仅关注膜两侧湿度的分布异常情况，未对膜两侧湿度的波动情况进行分析，无法准确预测风险的发生概率和严重程度，从而无法及时采取有效的应对措施来降低风险。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.
3、当防潮包装膜的防潮性能存在问题时，未重新设定防潮包装膜的厚度，并继续进行仿真操作，当防潮包装膜的防潮性能未存在问题时，未对防潮包装膜在各仿真湿度中的防潮性能进行仿真，未获取防潮包装膜的可适用湿度范围，无法确保包装膜在特定湿度条件下有效隔绝湿气，从而导致包装物受潮变质，无法延长产品的保质期，增加了因受潮导致的损失和浪费。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.
