[0036] By exerting external force, clamping plate 6 and clamping seat 7 are separated, and then self-sealing strip 5 connected with each other can be separated, top opening is realized, consumers can conveniently take dry fruits, after taking dry fruits, self-sealing strip 5 is accurately connected again, the sealing state of top is preliminarily restored, self-sealing strip 5 is fixed by connecting clamping plate 6 and clamping seat 7 again, the sealing effect of self-sealing strip 5 is strengthened, the top sealing effect is strengthened and the reliable guarantee of secondary sealing is realized, which helps to avoid the quality decline of dry fruits caused by improper sealing of bag body 1.
[0037] With reference to Figure 3 Side sealing assembly 9 includes sealing tear strip 10, sealing tear strip 10 is arranged on the outside of bag body 1, the middle part of mounting block 8 is provided with chain teeth 12, the side away from bag body 1 of chain teeth 12 is equipped with pull head 11, side sealing assembly 9 is connected together with bag body 1 through mounting block 8, the middle part of bag head 2 is provided with hanging hole 3.
[0038] By arranging sealing tear strip 10, pull head 11 and chain teeth 12 on the side of bag body 1, when opening for the first time, sealing tear strip 10 is opened, pull head 11 is pulled to drive chain teeth 12, so that the side of bag body 1 is opened, dry fruits are conveniently taken, after taking, pull head 11 is pulled reversely, chain teeth 12 is closed, the secondary sealing of the side of bag body 1 is realized, the design solves the problem of secondary sealing of traditional packaging bag, and provides the taking mode when the dry fruits in the packaging bag are less, and the user experience is improved.
[0039] Referring to Figure 1 and Figure 4 The composite assembly 13 comprises a heat-sealing layer 14 arranged on the inner wall of the bag body 1, and the material of the heat-sealing layer 14 is specifically polyethylene, which provides the heat-sealing layer 14 with heat-sealing property, sealing property and non-toxicity. The composite assembly 13 comprises a barrier layer 15 arranged on one side of the heat-sealing layer 14, and the material of the barrier layer 15 is specifically aluminum foil, which provides the barrier layer 15 with barrier property and protection property. The composite assembly 13 comprises a printing layer 16 arranged on the side of the barrier layer 15 away from the heat-sealing layer 14, and the material of the printing layer 16 is specifically biaxially oriented polypropylene, which provides the printing layer 16 with tensile resistance and smoothness.
[0040] By adopting polyethylene as the material of the heat-sealing layer 14, the heat-sealing layer 14 has good heat-sealing performance and non-toxicity, so that when the bag body 1 is manufactured, the reliable sealing of each side of the bag body 1 can be realized through the heat-sealing process, thereby forming a safe and closed space, effectively preventing external impurities from entering, and realizing the safe protection of the dried fruit package. By selecting aluminum foil as the material of the barrier layer 15, the barrier layer 15 has extremely low transmittance to oxygen, water vapor and light, so that during storage and transportation, the influence of external oxygen, water vapor and light on the dried fruit can be prevented in all directions, thereby preventing the oxidation, dampening and deterioration of the dried fruit due to light, and prolonging the shelf life of the dried fruit. By using biaxially oriented polypropylene to make the printing layer 16, the printing layer 16 has good tensile resistance and smooth surface, so that during use, the packaging bag is not easy to be damaged, and various printing processes can be easily implemented.
[0041] Working principle: when the bag body 1 is manufactured, the heat-sealing layer 14 adopts polyethylene to ensure the safety of the dried fruit package, the barrier layer 15 is aluminum foil to protect the dried fruit from the influence of external environmental factors in all directions, and the printing layer 16 is made of biaxially oriented polypropylene to facilitate the printing of various patterns and characters, thereby playing a role in product promotion and identification.
[0042] In daily use, when the consumer first opens the packaging bag, the operation is performed from the side. First, the sealing tear strip 10 is opened, and then the chain tooth 12 is pulled by the pull head 11 to open the side of the bag body 1, thereby facilitating the taking of the dried fruit. After taking, the chain tooth 12 is closed by the pull head 11 to realize the secondary sealing of the side.
[0043] If the dried fruit is taken from the top, a pair of self-sealing strips 5 that are clamped with each other play a role in the preliminary top sealing. When the self-sealing strips 5 need to be opened, the clamping plate 6 is separated from the clamping seat 7, and then the self-sealing strips 5 are separated. After taking, the self-sealing strips 5 are clamped again, and the clamping plate 6 and the clamping seat 7 are clamped and fixed again, thereby strengthening the top sealing effect and the secondary sealing effect.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
