Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a high-barrier packaging bag that prevents sticking. Background Technology

[0002] In the food, pharmaceutical, and chemical industries, packaging bags generally need to have both good barrier and anti-stick properties. Therefore, the packaging bags currently used usually adopt a multi-layer composite structure. For example, the multi-layer composite structure includes an outer layer that provides mechanical strength, a barrier layer that prevents water vapor and other substances from penetrating, and an inner layer that forms a cavity that contacts the contents. The inner layer usually has discrete raised dots or intermittent textures designed on its surface to reduce the contact area and prevent adhesion between the inner layers of the bag, thus ensuring the freshness, stability, and ease of use of the contents.

[0003] However, existing packaging bags rely solely on discrete raised dots or intermittent patterns for anti-sticking design. Due to the discontinuous nature of the raised dots, the contents tend to accumulate in the gaps, leading to localized adhesion. Furthermore, the raised dots are prone to collapsing under pressure, thus losing their anti-sticking function. In addition, the anti-sticking structure and the barrier structure are mostly designed independently, lacking functional synergy.

[0004] Therefore, based on the above situation, it is necessary to design a high-barrier packaging bag that prevents sticking to solve the above problems. Utility Model Content

[0005] This invention provides a high-barrier packaging bag that prevents sticking, thereby solving the problems in the prior art.

[0006] The technical problem solved by this utility model is achieved by the following technical solution: A high-barrier packaging bag that prevents sticking includes a bag body composed of an outer layer, a barrier layer, and an inner layer. The opening end of the bag body is provided with a self-sealing structure for sealing the bag body. The inner surface of the inner layer is provided with anti-sticking ribs that are spaced apart along the length of the bag body. The anti-sticking ribs are continuous protrusions, and a guide groove is formed between two adjacent anti-sticking ribs. The barrier layer has a pleated structure, and the extension direction of the pleats is intersected with the extension direction of the anti-sticking ribs. The barrier layer is connected to the outer layer and the inner layer through spaced connecting parts.

[0007] Preferably, the inner layer includes a first inner surface and a second inner surface disposed opposite to each other, wherein the anti-stick ribs on the first inner surface and the anti-stick ribs on the second inner surface are staggered in the width direction of the bag.

[0008] Preferably, the fold extension direction of the barrier layer is perpendicular to the extension direction of the anti-stick ribs.

[0009] Preferably, the connecting portion has a dotted structure and is distributed along the undulations of the barrier layer.

[0010] Preferably, the depth of the undulations in the barrier layer is the same.

[0011] Preferably, the opening edge of the bag body is provided with an elastic support member, which enables the opening to remain open in a natural state.

[0012] The beneficial effects of this utility model are: by setting continuous raised anti-stick ribs inside the bag, the problem of contents accumulating and sticking due to the continuous raised parts in the prior art is reduced. At the same time, the design of the pleated barrier layer with the outer and inner layers is connected at intervals. Combined with the pleated direction that intersects with the anti-stick ribs, the deformation resistance and barrier durability of the barrier layer are improved, and the overall structural stability of the bag is enhanced.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] Reference Figures 1-5As shown, a high-barrier packaging bag with anti-adhesion features a bag body 1 composed of an outer layer 11, a barrier layer 12, and an inner layer 13. The outer layer 11 acts as a barrier to the interior of the bag body 1, and the bag body 1 is sealed by a self-sealing structure 2 at its opening. This self-sealing structure 2 can be a snap-lock type, which is existing technology and will not be elaborated upon here. On the inner surface of the inner layer 13, anti-adhesion ribs 3 are spaced apart along the length of the bag body 1. These anti-adhesion ribs 3 are continuous raised structures, reducing the possibility of gaps due to discontinuous protrusions, which could cause the contents to accumulate and stick together, leading to adhesion between the inner walls of the bag body 1. A flow guide groove is formed between two adjacent anti-adhesion ribs 3. This continuous channel allows the contents inside the bag 1 to flow slowly and gradually detach from the guide groove when taken out or squeezed, avoiding the accumulation of contents in the same position for a long time, which is common with traditional dot-shaped protrusions. At the same time, in order to achieve efficient barrier against items inside the bag 1, the barrier layer 12 has a pleated structure. The extension direction of the pleats is intersected with the extension direction of the anti-stick ribs 3. The pleat direction and the anti-stick ribs 3 form a grid-like structure that complements each other, improving the tear resistance and tensile strength of the bag 1, thereby maintaining the integrity of the bag 1 and ensuring the barrier effect against oxygen, water vapor, etc. The two functions work together to further improve the high barrier performance of the bag 1 and the anti-stick performance between the inner walls of the bag 1.

[0018] Reference Figures 2-5 As shown, the inner layer 13 further includes a first inner surface and a second inner surface disposed opposite to each other. The anti-adhesion ribs 3 on the first inner surface and the anti-adhesion ribs 3 on the second inner surface are staggered in the width direction of the bag body 1. The staggered distribution makes the anti-adhesion ribs 3 on both sides form staggered support points in the width direction of the bag body 1, avoiding the inner wall from sticking due to lack of support in some areas, thereby reducing the possibility of the contents being stuck in the sticking area and forming adhesion.

[0019] Reference Figure 2 , Figure 3 As shown, further, the pleats of the barrier layer 12 extend in a direction perpendicular to the extension direction of the anti-adhesive ribs 3. The anti-adhesive ribs 3 extend along the length of the bag body 1, while the pleats in the vertical direction can provide cushioning in the width direction of the bag body 1. Together with the support of the anti-adhesive ribs 3 in the length direction, they form a vertical force network. The pleats themselves are elastic. When the bag body 1 is squeezed, the pleats deform first to absorb the external force, reducing the pressure transmitted to the inner layer 13 and preventing the anti-adhesive ribs 3 from being over-squeezed and failing. Because the pleat direction is perpendicular to the anti-adhesive ribs 3, it can also disperse external forces in different directions, forming a two-way buffer.

[0020] Reference Figure 3As shown, the connecting part 4 is a dotted structure and is distributed on the undulations of the barrier layer 12. If the folded barrier layer 12 is fully attached to the inner layer 13 and the outer layer 11, the folds are fixed and cannot deform, and the buffering function fails. By setting the connecting part 4, the deformation space of the folds can be preserved, and the unconnected areas can be freely stretched and contracted, ensuring that the elastic buffering function of the folds is not lost and the barrier enhancement effect of the folds is not weakened.

[0021] Among them, the undulation depth of the barrier layer 12 is the same. The uniform undulation depth can form a more coordinated spatial structure with the anti-stick ribs 3 and the flow guide groove, avoiding irregular gaps between it and the anti-stick ribs 3 due to excessive local undulation depth, or affecting the flow guide groove's drainage function due to excessive shallowness. This ensures that the anti-sticking and flow guide functions are consistent in all areas of the bag body 1, improving the overall usage effect.

[0022] Reference Figure 4 , Figure 5 As shown, furthermore, an elastic support 5 is provided at the edge of the opening of the bag body 1. The elastic support 5 can keep the opening open in a natural state, such as a "U" shape or an "O" shape. The elastic support 5 can be made of food-grade elastic plastic, elastic rubber, or other materials, so that the opening of the bag body 1 remains open in a natural state, without the need to manually open the bag opening. This facilitates one-handed operation or retrieval of non-flowing contents, reducing spillage. At the same time, the continuous opening can reduce the probability of fingers or external impurities coming into contact with the remaining contents inside the bag during retrieval, thus reducing the risk of contamination to a certain extent.
