In the food market, jelly is a very popular dessert. It has a refreshing taste and bright colors, making it perfect for a casual snack or dessert.
Jelly is usually packaged in plastic or cardboard boxes, with a variety of cute patterns and colors on the exterior to attract children's attention. The firmness of the jelly cup lid film composite film refers to the adhesion between the jelly cup lid film and the composite film, that is, the adhesion between them. This firmness is one of the important indicators to evaluate the quality of the jelly cup, as it directly affects the sealing and durability of the jelly cup.
Instrument Recommendation:Ett-Am Jelly Cup Lid Film Firmness Tensile Tester
The test principle of tensile testing machine for the firmness of the film of the jelly cup lid
The fixture of the equipment is divided into upper and lower, the upper fixture can move according to the preset speed, and the lower fixture remains fixed. During the test, the two ends of the sample are clamped in the upper and lower fixtures respectively, with the movement of the upper fixture, the sample is peeled, stretched or torn and other damage, and the force value and displacement changes generated by the change of the sample are respectively monitored by the force value sensor and the displacement sensor on the dynamic chuck, and according to the monitoring results, the peel strength, tensile force, deformation rate and other properties of the sample are calculated.
Jelly cup lid film firmness tensile testing machine test process
1) Cut 5 specimen strips with a width of 15 mm and a length of 200 mm along the horizontal and longitudinal directions of the sample.
2) Each specimen strip is manually peeled 50 mm in advance.
3) The two ends of the stripping part of the specimen are clamped in the upper and lower fixtures of the equipment respectively, and the longitudinal axis of the stripping part of the specimen coincides with the centerline of the upper and lower fixtures.
4) Set the test speed, specimen width and other parameter information, click the test option, and the test starts.
5) The equipment automatically detects the change of force value during the test, and calculates and displays the final peel strength value of the sample according to the detected data.

Application scenario of tensile testing machine for the firmness of the film of the jelly cup lid.
The tensile testing machine for the firmness of the jelly cup lid film is mainly used to test the tensile performance and firmness of the jelly cup lid film. In the world of food packaging, jelly is a common snack, and jelly lid film is a key ingredient used to protect jelly and maintain its freshness. Therefore, it is essential for the quality control of jelly cup lid films.
First of all, the jelly cup lid film needs to have good tensile properties. This is because the jelly lidding film needs to be heat-sealed and stretched during the production process to ensure its tightness and integrity. By using a tensile testing machine for the firmness of the jelly lid, it is possible to test the performance of the jelly lidding film under different tensile conditions and thus evaluate the elasticity and plasticity of the material.
Secondly, the jelly lid film needs to be strong enough. This is because jelly cups may be subjected to external forces during transportation and sales, and if the jelly cup lid film is not strong enough, it may lead to seal failure or breakage. By using a tensile testing machine for the firmness of the jelly cup lid film, a tensile and tear test can be performed on the jelly cup lid film to evaluate its ability to withstand external forces.
In addition, the tensile testing machine for the firmness of the jelly cup lid film can also be used to test other materials related to food packaging, such as plastic film, cardboard, etc. Therefore, the device has a wide range of application prospects in the field of food packaging and materials science.
In a word, the tensile testing machine for the firmness of the jelly cup lid film is one of the important tools for the quality control of food packaging. By using this equipment, the quality and reliability of the jelly cup lid film can be ensured, so as to provide consumers with safer and healthier food packaging.
