A type of packaging bag that allows for easy ventilation. Technical Field

[0001] This utility model relates to the field of packaging bag technology, and more specifically, it relates to a packaging bag that allows for easy air venting. Background Technology

[0002] Packaging bags are materials used to cover products, and their design helps prevent packaged items from falling apart.

[0003] Existing packaging bags for clothing products generally have ventilation holes for air to enter and exit. However, when the goods are squeezed, the ventilation holes are easily blocked, making it difficult for the packaging bag to release air and causing the packaging bag to crack.

[0004] Therefore, a new solution is needed to supplement the existing packaging bag categories. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a packaging bag that allows for easy air venting.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an easily venting packaging bag, comprising a bag body, wherein the bag body has multiple vent holes and two covering strips are provided, the two covering strips are X-shaped and form a covering of the vent holes, the covering strips are bonded to the bag body through their two long sides, a channel is formed between the bag body and the covering strips, and the vent strips are fitted into the channel area.

[0007] The present invention is further configured such that: the cross-section of the breathable strip is formed in the shape of a cashew nut, one side of the inner arc surface of the breathable strip faces the bag body, and the breathable hole and the inner arc surface area of ​​the breathable strip are interconnected.

[0008] The present invention is further configured such that: one end of the covering strip is provided with a slit, the slit allowing a breathable strip to be inserted between the covering strip and the bag body.

[0009] The present invention is further configured such that: a connecting strip is provided at the end of the covering strip away from the tear, and the connecting strip forms an adhesive connection to the bag body.

[0010] The present invention is further configured such that: both the bag body and the covering strip are made of polyethylene material, and the breathable strip is made of polypropylene material.

[0011] The present invention is further configured such that: an adhesive strip is provided at the bag opening area of ​​the bag body.

[0012] In summary, this utility model has the following beneficial effects: compared with ordinary packaging bags, this bag can form a structure that prevents the air vents from being blocked, so that when the bag contains soft items and is squeezed, air can be discharged in time, and the bag will not burst due to swelling.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A type of easily ventilated packaging bag, as shown in Figures 1-3, includes a bag body 1. The bag body 1 has multiple ventilation holes 2 and two covering strips 3 arranged in an X-shape, covering the ventilation holes 2. The covering strips 3 are adhesively connected to the bag body 1 via their two long sides. A channel is formed between the bag body 1 and the covering strips 3, and a ventilation strip 4 is fitted into the channel area. The covering strips 3 on the bag body 1 are designed to allow the ventilation strip 4 to be inserted, enabling the ventilation strip 4 to... The ventilation hole 2 area of ​​the bag body 1 forms a space. When the bag body 1 is filled with something and needs to be vented when it is stacked, the air can be discharged to the outside of the bag body 1 through the ventilation hole 2 and the ventilation strip 4. The cross-section of the ventilation strip 4 is formed in the shape of a cashew nut, and the inner arc side of the ventilation strip 4 faces the direction of the bag body 1. The ventilation hole 2 and the inner arc side area of ​​the ventilation strip 4 are interconnected. The cashew nut-shaped cross-section of the ventilation strip 4 allows air to pass between the bag body 1 and the ventilation strip 4 so as to facilitate the discharge of air.

[0019] One end of the covering strip 3 has a slit 5, which allows the breathable strip 4 to be inserted between the covering strip 3 and the bag body 1. The slit 5 allows the breathable strip 4 to be inserted and removed. Users can freely choose whether to install the breathable strip 4 between the bag body 1 and the covering strip 3 so that other items can be placed in the packaging bag. After the breathable strip 4 is inserted between the covering strip 3 and the bag body 1, the end of the covering strip 3 away from the vent hole 2 can form a fit with one end of the breathable strip 4, preventing the breathable strip 4 from protruding from the slit 5. The end of the covering strip 3 away from the slit 5 is provided with a connecting strap 6, which forms an adhesive connection with the bag body 1. The other end of the breathable strip 4 is restricted by the connecting strap 6, achieving the positioning effect of the breathable strip 4.

[0020] Both the bag body 1 and the covering strip 3 are made of polyethylene material. Polyethylene material is non-toxic and widely used in the manufacture of plastic bags. The breathable strip 4 is made of polypropylene material. The breathable strip 4 made of polypropylene material is elastic and can adapt to the deformation of the bag body 1. The bag body 1 has an adhesive tape 7 at the bag opening area. The adhesive tape 7 is used to seal the bag opening area of ​​the bag body 1.
