[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] The present application embodiment discloses a drawstring type plastic packaging bag, referring to Figure 1 and Figure 2 The plastic packaging bag includes a bag body 1, the bag opening of the bag body 1 is folded from the inside to the outside to form a flange 2, and a rope outlet 21 is opened on the flange 2. There are four rope outlets 21 and every two rope outlets 21 form a group. The two groups of rope outlets 21 are respectively located on one side of the two ends of the flange 2 in the length direction. The rope outlet 21 is connected with the inside of the flange 2. A rope 3 is passed through the flange 2, and the two ends of the rope 3 extend out of the two rope outlets 21 at one end of the flange 2 in the length direction. A section of the rope 3 away from its two ends is located at the two rope outlets 21 at the other end of the flange 2 in the length direction. The two ends of the rope 3 are jointly connected with a tightening component 4, and a compression hole 22 is opened on the side of the flange 2 facing the inside of the bag body 1. A plurality of compression holes 22 are spaced apart along the length direction of the flange 2.

[0034] Reference Figure 3 The clamping assembly 4 includes a base 41, and a clamping block 42 is clamped on the side of the base 41 facing the rope 3. The base 41 and the clamping block 42 are processed to form protrusions 43 on the opposite sides. The side walls on both sides of the length direction of the base 41 are processed to form clamping joints, and the side walls on both sides of the length direction of the clamping block 42 are processed to form clamping seats that match the clamping joints. The rope 3 is clamped and fixed between the base 41 and the clamping block 42.

[0035] When using the plastic packaging bag, put the items into the bag body 1, lift the rope 3 extending from the rope outlet 21, and pull the rope 3 out of the rope outlet 21. At the same time, the bag opening of the bag body 1 is pushed and tightened by the rope 3. The compression hole 22 can reduce the accumulation of the inner wall of the bag opening and improve the sealing of the bag opening of the plastic packaging bag. The base 41 and the clamping block 42 are clamped together to press the two ends of the rope 3. The protrusion 43 can increase the friction between the pressing component 4 and the rope 3. When the rope 3 is damaged and needs to be replaced, Open the base 41 and the block 42 and pull the rope 3 out of the flange 2, and respectively insert the two ends of the new rope 3 into the two rope outlets 21 at one end of the flange 2 in the length direction, and then pass the two ends of the rope 3 through the flange 2 and out from the two rope outlets 21 at the other end of the flange 2 in the length direction. Use the clamping component 4 to press and fix the two ends of the rope 3. The compression hole 22 makes it easy to pass the rope 3 through the flange 2. The clamping component 4 makes it easy to press and fix the two ends of the rope 3, which facilitates the reuse of the drawstring plastic packaging bag.

[0036] Reference Figure 1 The base 41 and the clamping block 42 are both curved in an arc shape. A handle block 5 is provided on a portion of the circumference of the drawstring 3 away from its end. The handle block 5 is made of a strip of plastic and is curved in an arc shape. When using this plastic packaging bag, the user lifts the drawstring 3 by lifting the pressing assembly 4 and the handle block 5. The curved base 41, clamping block 42, and handle block 5 increase the user's comfort when lifting the drawstring 3, while also reducing the risk of damage to the drawstring 3 when the plastic packaging bag is hung, facilitating the reuse of the drawstring plastic packaging bag.

[0037] Reference Figure 1 A reinforcement strip 23 is formed on the side of the cuff 2 facing the interior of the bag body 1. Multiple reinforcement strips 23 are provided at intervals along the length of the cuff 2. When using this plastic packaging bag, the reinforcement strips 23 can increase the structural strength of the cuff 2, reduce the deformation of the cuff 2 when the user lifts the strap 3, and reduce the risk of damage to the cuff 2 when the user lifts the strap 3, thereby facilitating the reuse of the drawstring plastic packaging bag.

[0038] Reference Figure 2 The opening of the rope outlet 21 is processed into an elliptical shape. When the plastic packaging bag is used, the elliptical rope outlet 21 can increase the structural strength of the rope outlet 21, reduce the deformation of the rope outlet 21 when the user lifts the rope 3, and facilitate the reuse of the drawstring plastic packaging bag.

[0039] Reference Figure 2 The hole of the rope outlet 21 is processed to form a protruding ring. When using the plastic packaging bag, the protruding ring 211 can increase the structural strength of the rope outlet 21, reduce the deformation of the rope outlet 21 when the user lifts the rope 3, and facilitate the reuse of the drawstring plastic packaging bag.

[0040] Reference Figure 2 An elastic strip 24 is bonded to the side of the cuff 2 facing away from the interior of the bag body 1. In this embodiment, the elastic strip 24 is made of elastic plastic. When the plastic packaging bag is used, the elastic strip 24 can prop the bag opening open when the user opens the plastic packaging bag. At the same time, it can increase the structural strength of the cuff 2, reduce the deformation of the cuff 2 when the user lifts the rope 3, and reduce the risk of damage to the cuff 2 when the user lifts the rope 3, making it easier for the user to open the bag opening.

[0041] Reference Figure 1 The outer wall of the bag body 1 is formed with reinforcing ribs 6, which are spaced apart along the length of the flap 2. One end of the reinforcing rib 6 is connected to the flap 2 on one side of the bag body 1, and the other end is connected to the flap 2 on the other side of the bag body 1. When the plastic packaging bag is used, the reinforcing ribs 6 can increase the overall structural strength of the bag body 1, facilitating the reuse of the drawstring plastic packaging bag.

[0042] Reference Figure 1 The side walls of the bag body 1 on both sides in the length direction are processed to form folds 7. When using the plastic packaging bag, the user can fold the bag body 1 along the folds 7 to reduce the space occupied by the plastic packaging bag, making it easier for the user to store the plastic packaging bag and facilitate the reuse of the drawstring plastic packaging bag.

[0043] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
