The air holes are distributed in the two sides of the packaging bag, the situation that the air holes are blocked by the upper packaging bag and the lower packaging bag during stacking is avoided, the overall strength of the bag body is affected due to the fact that the air holes are formed in the upper end and the lower end of the packaging bag, and the bag body is easily blocked by content; by optimizing the size, the spacing and the arrangement mode of the pore diameters of the air holes, control over the exhaust effect is achieved, and packaging bags are not prone to toppling over in the stacking process and after stacking.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of packing bag, especially relates to a breathable sealing packing bag. BACKGROUND

[0002] The packing bag can realize the packaging of various products, makes goods convenient to transport in the production flow process, is easy to store and is widely applied to the packaging of various articles, especially dried food. In order to facilitate shelf display and the requirement of consumer immediate unpacking and eating, the size range of food packing bag is usually between 5-30cm, but the packaging cost and transportation cost of this smaller size packing bag are higher. Generally, the larger the size of the packing bag, the larger the packaging volume and the lower the cost, but the requirement of the packing bag in anti-falling and anti-puncture is higher. In addition to this, during transportation and shelf display, the packing bag with large weight is generally stacked, and the previous food packing bag is prone to sliding after stacking due to various reasons.

[0003] The existing packing bag is prone to sliding during stacking, which is usually due to the following reasons: in order to meet the packaging requirement, the sealing property of the packing bag is required to be high, if there are more gases in the packing bag during the packaging process, the gases cannot be discharged after sealing, so that the packing bag cannot be completely attached to each other, and a stable stacking structure cannot be formed. SUMMARY

[0004] The utility model provides a breathable sealing packing bag, which can effectively solve the above problems.

[0005] The utility model is implemented as follows:

[0006] A breathable sealing packing bag, comprising a bag body, wherein both sides of the bag body are provided with air holes.

[0028] Referring to Figures 1-4 As shown in the drawings, a breathable sealing packaging bag comprises a bag body 1, and air holes 2 are arranged on both sides of the bag body 1.

[0029] Through experimental tests, it is found that the air holes 2 arranged on the surface or upper and lower end positions of the bag body 1 are easy to be blocked, which affects the exhaust effect and the overall strength of the bag body 1.

[0030] Further, the diameter of the air hole 2 is 1-5mm.

[0031] Further, 10-50 air holes 2 are arranged on one side of the bag body 1, and the spacing between adjacent air holes 2 is 5-25mm. More preferably, 30-40 are arranged on one side.

[0032] The above diameter, number and spacing design can ensure the exhaust effect of the packaging bag and meet the strength requirement of the packaging bag.

[0033] Further, the number of air holes 2 on one side is an integer 40-50 times the reciprocal of the diameter value, and the spacing of the air holes 2 is 4-5 times the diameter.

[0034] The size of the air holes 2 affects the exhaust effect. If the air holes 2 are too small, the exhaust is not conducive, and problems such as blockage are prone to occur. If the air holes 2 are too large, the strength of the bag body 1 is affected, and the contents are also prone to leakage. The number of air holes 2 on one side is an integer of 40-50 times the reciprocal of the diameter of the air holes 2, and the spacing of the air holes 2 is 4-5 times the diameter of the air holes 2. The exhaust effect of the air holes 2 and the strength of the packaging bag are comprehensively considered. The air holes 2 are arranged in an orderly manner, and preferably, the adjacent air holes 2 are staggered or arranged in a curved manner.

[0035] Further, the air holes 2 are arranged in the middle of the two sides of the bag body 1.

[0036] Further, the density of the air holes 2 in the middle region is greater than that on the two sides and at the two ends.

[0037] Further, the pore size of the air holes 2 in the middle region is greater than that on the two sides and at the two ends.

[0038] Further, the pore size of the air holes 2 gradually decreases from the middle to the two sides and the two ends.

[0039] Further, the air holes 2 are arranged in an arc shape.

[0040] Further, the air holes 2 are arranged in an arc shape from the two ends to the center of the bag body 1.

[0041] The air holes 2 are arranged in the middle position, which can quickly exhaust the gas in the bag and ensure that the gas in the middle position of the bag body 1 is preferentially exhausted, while the upper and lower end positions and the four corners of the bag body 1 remain inflated, thereby ensuring that the packaging bag stack can be kept stable during the early exhaust process. Further, the density of the air holes 2 in the middle region is greater than that on the two sides and at the two ends, or the pore size of the middle region is greater than that on the two sides and at the two ends, or the pore size gradually decreases from the middle to the two sides and the two ends, so that the exhaust speed in the middle is greater than that on the two sides and at the two ends, thereby ensuring that the center of gravity of the packaging bag is located at the center position during the exhaust process, and the four corners are relatively in a state of inflation due to the slow exhaust speed, thereby playing a supporting role and avoiding tilting.

[0042] Further, the air holes 2 are arranged on at least the back of the bag body 1. Arranging the air holes 2 only on the back of the bag body 1 has better aesthetics.

[0043] Further, at least one surface of the bag body is provided with an anti-slip layer, and the anti-slip layer is composed of a plurality of anti-slip blocks.

[0044] The anti-slip blocks are rectangular, square or other regular polygons, and circular or elliptical.

[0045] The anti-slip blocks are arranged in an orderly and spaced manner on the surface of the bag body.

[0046] The anti-skid blocks are arranged in concentric intervals on the surface of the bag body.

[0047] The distribution density of the anti-skid blocks in the middle region and the periphery is greater than that in other positions.

[0048] The area of the central region of the anti-skid blocks accounts for 20-30% of the total area of the anti-skid layer, and the distribution area of the periphery of the anti-skid blocks accounts for 30-40% of the total area of the anti-skid layer.

[0049] The anti-skid blocks are in cross distribution.

[0050] The anti-skid blocks are in four-corner and central distribution.

[0051] By arranging the anti-skid blocks on the surface of the bag body, the ventilation effect of the packaging bag can be effectively improved, the packaging bag can be prevented from tilting during the ventilation process, the center of gravity of the packaging bag stack can be maintained, and the packaging bag after ventilation is more flat, has a large stress area, and is more stable.

[0052] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
