Embodiment Construction
[0012] The specific implementation of the present invention will be further described below in conjunction with examples.
[0013] Such as figure 1 As shown, a packaging film that can reconcile a variety of food / cosmetics includes an upper film and a lower film. The upper film is a flat film. The upper film and the lower film are heat-sealed along the heat-sealing path to form a plurality of independent voids. The heat-sealing path includes a heat-sealed section belonging to one cavity alone and a barrier section shared between two adjacent cavities. The bonding strength of the upper and lower films at the barrier section is much smaller than that of the upper and lower films at the heat-sealed section. The bonding strength of the lower membrane.
[0014] The ratio of the bonding strength of the upper film and the lower film at the barrier section to the bonding strength of the upper film and the lower film at the heat-sealing section is 1:10.
[0015] The binding force of the uppe...
