[0022] The technical solution of the present application is further described in detail below through specific embodiments and in combination with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0023] Example 1
[0024] like Figures 1 to 3 As shown, in the present embodiment, a food packaging bag 10 is provided, comprising: two films 100 and an easy-tear guide strip 200 which are arranged overlappingly in the front and back; the left and right edges of the two films 100 are sealed and connected, the bottom ends of the two films 100 are opened to form a feed port 120, the top ends of the two films 100 are arranged as a positioning area 110 corresponding to the width of the food, the easy-tear guide strip 200 is connected to the inner surface of the front film 100, and the easy-tear guide strip 200 is at least partially arranged to overlap with the positioning area 110, a sealing line 300 is arranged on the easy-tear guide strip 200 and the positioning area 110, a tear notch 400 for guiding the unsealing along the direction of the easy-tear guide strip 200 is opened on the positioning area 110 of the front film 100, and the ratio of the width of the easy-tear guide strip 200 to the width of the positioning area 110 is 3:5 to 4:5.
[0025] Specifically, the material of the two films 100 is set to be plastic, such as polyethylene, and the two films 100 are arranged front and back to face each other, and the edges on the left and right sides are heat-sealed and connected by fusion. The tops of the two films 100 are positioning areas 110. The shapes of the two films 100 can be: the positioning area 110 is square, the middle part is a trapezoid with narrow top and wide bottom, and the bottom is square. The width of the positioning area 110 is slightly larger than the width of the food to package the food. In this embodiment, the food can be a sandwich, and it can also be other food packaged in a packaging bag. The easy-tear guide strip 200 is used to guide the tearing of the front film 100. The top of the easy-tear guide strip 200 is overlapped with the positioning area 110, and the top of the easy-tear guide strip 200 is fused and heat-sealed with the positioning areas 110 of the two films 100 to form a strip-shaped sealing line 300 to seal the positioning areas 110 of the two films 100, ensure the integrity of the food packaging bag 10 and effectively protect the food, and the top surface of the easy-tear guide strip 200 is protruding from the sealing line 300. The tearing opening 400 is opened on the front film 100 as the opening starting point. The width of the easy-tear guide strip 200 and the width of the positioning area 110 are produced in a ratio of 3:5 to 4:5 according to actual production needs. For example, the width of the easy-tear guide strip 200 and the width of the positioning area 110 are produced in a ratio of 3:5; for another example, the width of the easy-tear guide strip 200 and the width of the positioning area 110 are produced in a ratio of 3.5:5; for another example, the width of the easy-tear guide strip 200 and the width of the positioning area 110 are produced in a ratio of 4:5. For example, when the width of the food packaging bag 10 is 50MM, the width of the easy-tear guide strip 200 is 30MM, 35MM or 40MM.
[0026] Thus, when in use, the sandwich is put in through the feed port 120, and then the bottom ends of the two films are folded and pasted to seal the feed port 120, so that the sandwich is completely sealed in the food packaging bag 10. When the consumer opens the package, a pulling force is applied to the tearing opening 400, so that the easy-tear guide strip 200 can be torn off through the tearing opening 400, and at the same time, the easy-tear guide strip 200 can tear the film 100 in front, so that the sandwich can be almost completely exposed. Among them, by producing the width of the easy-tear guide strip 200 and the width of the positioning area 110 in a ratio of 3:5 to 4:5, the width of the easy-tear guide strip 200 is widened, avoiding the need to tear the packaging film to both sides again, and the easy-tear effect can be better, which is very convenient to take out the sandwich for consumption.
[0027] In order to achieve a better tearing effect when the food packaging bag 10 is torn, in one embodiment, an easy-tear coating is provided at a position of the easy-tear guide strip 200 close to the sealing line 300 .
[0028] Specifically, the top of the easy-tear guide strip 200 is provided with an easy-tear coating, and the easy-tear coating is connected to the front and rear films 100. In this way, while ensuring the sealing performance, the easy-tear guide strip 200 can be completely peeled off from the sealing line 300 to avoid tearing the food packaging bag 10, thereby maintaining the integrity of the food packaging bag 10, so that the food packaging bag 10 has a better effect when being torn.
[0029] In order to facilitate tearing the food packaging bag 10 along the direction of the easy-tear guide strip 200, as shown in FIG. Figure 2 and Figure 3 As shown, in one embodiment, the width of the tear notch 400 is greater than the width of the easy-tear guide strip 200 .
[0030] Specifically, by setting the width of the tear 400 to be larger, the tear 400 is not easily damaged when the food packaging bag 10 is torn open, and the food packaging bag 10 is easily torn open along the direction of the easy-tear guide strip 200, thereby achieving a better tearing effect.
[0031] In order to facilitate tearing the food packaging bag 10 along the direction of the easy-tear guide strip 200, as shown in FIG. Figure 2 and Figure 3 As shown, in one embodiment, the bottom end of the tear notch 400 is concavely arranged so that the tearing direction is toward the easy-tear guide strip 200 .
[0032] Specifically, by guiding the bottom end of the tear 400 inward, that is, toward the direction of the easy-tear guide strip 200, it is possible to effectively avoid tearing the food packaging bag 10 due to the bottom end of the tear 400 facing outward, thereby increasing the practicality of the food packaging bag 10.
[0033] In order to facilitate tearing the food packaging bag 10 along the direction of the easy-tear guide strip 200, as shown in FIG. Figure 2and Figure 3 As shown, in one embodiment, the bottom end of the tear notch 400 is inclined inwardly by 30° to 45°.
[0034] Specifically, by tilting the bottom end of the tear notch 400 inward by 30° to 45°, the tearing direction can be effectively ensured to be inward, thereby effectively preventing the tear line from tilting outward and tearing the bag. The angle is set according to actual production needs, for example, the bottom end of the tear notch 400 tilts inward by 30°; for another example, the bottom end of the tear notch 400 tilts inward by 37.5°; for another example, the bottom end of the tear notch 400 tilts inward by 45°.
[0035] To facilitate the removal of sandwiches, Figure 1 and Figure 2 As shown, in one embodiment, two overlapping films 100 form a bag body 500 for containing food, and the easy-tear guide strip 200 is arranged on the long side of the food.
[0036] Specifically, the easy-tear guide strip 200 is configured as a rectangular strip, and the easy-tear guide strip 200 is connected to the middle of the front film 100. By configuring the easy-tear guide strip 200 on the long side of the sandwich, it is very convenient to take out or eat the sandwich directly after tearing the tear opening 400.
[0037] To facilitate the removal of sandwiches, Figure 1 and Figure 2 As shown, in one embodiment, the length of the easy-tear guide strip 200 is the same as the length of the long side of the food.
[0038] Specifically, by making the length of the easy-tear guide strip 200 the same as the length of the long side of the sandwich, the easy-tear guide strip 200 can pass through the entire sandwich after packaging the sandwich, thereby ensuring the opening length of the food packaging bag 10, that is, after tearing the tear notch 400, the entire sandwich can be exposed, which is very convenient to take out and eat. For example, when the food packaging bag 10 is a 50MM model, the length of the easy-tear strip is 165MM.
[0039] In order to facilitate the use of the tear 400, as Figures 1 to 3 As shown, in one embodiment, the top of the tear 400 is configured as an arc-shaped edge or a straight edge.
[0040] Specifically, a tear 400 is formed in the middle of the top of the front film 100 as the opening starting point. The shape of the tear 400 is set according to actual production requirements, so as to achieve tearing of the tear 400 in the direction from the sealing line 300 to the easy-tear guide strip 200. For example, the top of the tear 400 is set as an arc edge. In this way, it is more beautiful and has a larger contact area for human hands, such as the top of the tear 400 is set as an arc shape; for another example, the top of the tear 400 is set as a straight edge. For example, the top of the tear 400 is an inverted V shape.
[0041] In order to facilitate the connection between the easy-tear guide strip 200 and the front film 100, as Figure 2 As shown, in one embodiment, a connection line 600 is provided between the easy-tear guide strip 200 and the front film 100 .
[0042] Specifically, the easy-tear guide strip 200 is connected to the film 100 via the connection line 600 , so that the easy-tear guide strip 200 can be fixed on the inner surface of the front film 100 .
[0043] In order to facilitate the connection between the easy-tear guide strip 200 and the front film 100, as Figure 2 As shown, in one embodiment, the connection line 600 is configured as two adhesive layers disposed at intervals.
[0044] Specifically, the easy-tear guide strip 200 and the film 100 are connected via two adhesive layers, so that the connection between the easy-tear guide strip 200 and the front film 100 is more stable.
[0045] Example 2
[0046] This embodiment is a further preferred embodiment of Embodiment 1. In this embodiment, an anti-fouling film is provided inside the bag body 500 .
[0047] Specifically, the side of the easy-tear guide strip 200 facing away from the front film 100 is covered with a square anti-fouling film, so that when a sandwich is placed in the food packaging bag 10 , a small amount of oil stains from the sandwich will not contaminate the food packaging bag 10 .
[0048] In order to facilitate taking the food packaging bag 10 , in one embodiment, an anti-slip layer is provided on the positioning area 110 .
[0049] Specifically, the anti-skid layer is configured as anti-skid patterns, which increase the friction of the positioning area 110 and prevent slipping when the food packaging bag 10 is opened.
[0050] Example 3
[0051] This embodiment is a further preferred embodiment of the embodiment 1. In this embodiment, a guide strip for guiding the tearing of the tearing edge 400 is provided on the positioning area 110 of the front film 100 .
[0052] Specifically, the guide strip is used to guide the tear 400 to leave the positioning area 110 , and the guide strip is bonded to the front film 100 . The guide strip is provided to facilitate tearing the tear 400 , thereby effectively increasing the practicality of the food packaging bag 10 .
[0053] In one embodiment, the positioning area 110 is fused and sealed all around.
[0054] Specifically, to further ensure the sealing performance.
