Packaging performance test is an important means to evaluate the performance of packaging materials, and its results have an important impact on the selection of packaging materials. This article will detail the content, methodology, and how the results affect the choice of packaging materials.
First, the content of the packaging performance test.
The packaging performance test mainly includes the following aspects:
1.Mechanical property test: It mainly tests the mechanical properties of packaging materials such as compression, tensile and impact resistance to evaluate their resistance during transportation and storage.
2.Barrier performance test: It mainly tests the barrier performance of packaging materials, such as air tightness, water vapor transmission rate, etc., to evaluate its ability to protect the contents.
3.Weather resistance test: It mainly tests the weather resistance of packaging materials under various environmental conditions, such as ultraviolet resistance, high and low temperature resistance, etc., to evaluate its stability under various environmental conditions.
4.Hygienic performance test: It mainly tests the hygienic performance of packaging materials, such as sterility, non-toxicity, etc., to ensure its safety to the contents.
Second, the method of packaging performance test.
There are several main methods of packaging performance testing:
1.Experimental method: Through simulation experiments in the laboratory, various performance tests are carried out on packaging materials.
2.Practical application method: The packaging material is applied to the actual product and its performance is evaluated through actual use.
3.Data analysis method: Evaluate the performance of packaging materials through statistical analysis of a large amount of data.
3. The impact of the results of the packaging performance test on the packaging materials.
1.Mechanical properties test results: If the mechanical properties of the packaging material are poor, it is easy to be damaged or deformed during transportation and storage, so it is necessary to choose a packaging material with high mechanical properties.
2.Barrier performance test results: If the barrier performance of the packaging material is poor, the contents are easily affected by the external environment and deteriorate or damage, so it is necessary to choose a packaging material with good barrier performance.
3.Weather resistance test results: If the weather resistance of the packaging material is poor, it is easy to age or deteriorate under various environmental conditions, so it is necessary to choose a packaging material with good weather resistance.
4.Hygienic performance test results: If the hygienic performance of the packaging material is not up to standard, it will cause pollution or endanger human health to the contents, so it is necessary to choose packaging materials with good hygienic performance.
In summary, the results of packaging performance tests have an important impact on the selection of packaging materials. When choosing packaging materials, it is necessary to consider comprehensively according to the characteristics and actual needs of the product, and choose packaging materials with good mechanical properties, barrier properties, weather resistance and hygienic properties to ensure the safety and stability of the product.
