The performance of Zongzi packaging bag is an important factor that affects whether Zongzi can be preserved well in the storage process. The soft plastic composite film packaging of Zongzi is generally divided into inner packaging and outer packaging. This paper analyzes the testing points of these two packaging performance respectively, and introduces the testing methods of each performance, providing a reference for enterprises to monitor the quality of soft plastic composite film materials used to package Zongzi.

1. Meaning

Zongzi is a traditional festival food in China. With the extension of storage time, its packaging form has gradually evolved from the traditional single zongzi leaf packaging to the double packaging form of zongzi leaf plus soft plastic composite film. Most of the common soft plastic composite film materials used for packaging Zongzi are plastic composite films. These plastic composite films can be divided into inner packaging and outer packaging according to whether they are in direct contact with Zongzi. Each kind of packaging plays a different role. The inner packaging focuses on the protection of Zongzi ingredients to prevent Zongzi from deterioration, while the outer packaging focuses on the protection of packaging integrity to prevent bag breakage. Therefore, the focus on the performance of inner and outer packaging should be different. This paper analyzes the key points of the inspection of the inner and outer packaging of Zongzi packaging.

2. Barrier performance

There are many varieties of Zongzi, such as meat zongzi, bean paste zongzi, jujube zongzi, ham zongzi, eight treasure zongzi, egg yolk zongzi, etc. The composition of Zongzi determines that it is easy to be oxidized, deteriorated and mildewed. Therefore, high oxygen barrier performance is the basic requirement for Zongzi packaging. From the completion of packaging to consumption, the inner packaging should always ensure that Zongzi is in a closed environment, so the composite film materials used in the inner packaging have good oxygen resistance performance, which will have a good quality assurance effect on Zongzi.

3. Physical and mechanical properties

The good physical and mechanical properties of the flexible plastic packaging materials can make it work well with the packaging equipment, successfully complete the packaging process, and ensure that the Zongzi packaging bags will not break, leak or delaminate during storage and sales, and have a good appearance.

3.1 Flexibility

The inner packaging of Zongzi is usually vacuum packaging, and good flexibility can make the packaging materials stick well on the surface of Zongzi, which is convenient to remove the air in the packaging bag; The good flexibility of the outer packaging bag can prevent it from breaking when dropped or impacted by foreign objects.

3.2 Puncture resistance

The bulges formed on the inner packaging surface of Zongzi are generally hard, which will have a greater puncture force on the contacting packaging materials. Therefore, both the inner packaging and the outer packaging should have a strong puncture resistance to ensure that the packaging bag will not be broken due to the puncture effect of sharp corners.

3.3 Heat sealing strength

The heat sealing strength is a performance index that represents the sealing fastness of the packaging bag. If the heat sealing strength of the packaging bag is poor, the sealing is not firm or the heat sealing is excessive, then slow air leakage will occur during the storage and sales of Zongzi, and problems such as bag swelling, mildew, deterioration will occur, or the bag will break at the seal when falling or being impacted by foreign objects. Whether the heat sealing strength of Zongzi packaging bag is good or not is related to the factors such as the heat sealing layer of inner packaging and outer packaging materials, heat sealing temperature, pressure, time, etc.
