Description

Technical Field

[0001] The present application relates to the field of packaging bags, and in particular to an environmentally friendly plastic packaging bag. Background Art

[0002] Plastic bags, primarily made from nitrocellulose, are essential for daily life and are often used to store other items. They are widely used in production and daily life due to their low cost, extremely light weight, large capacity, and easy storage. While they offer convenience to consumers, plastic bags, often made from polypropylene, polyester, nylon, and other materials, are associated with long degradation cycles, difficult disposal, and environmental pollution. For these reasons, an increasing number of countries and regions have implemented restrictions on their production, sale, and use.

[0003] Most existing plastic packaging bags are vest-type packaging bags, which include a packaging bag body with a bag opening on the upper part. Two handles are formed at the edge of the bag opening and are symmetrically distributed on the packaging bag body.

[0004] The above-mentioned existing technical solutions have the following defects: after using the packaging bag to hold items, in order to prevent the items in the packaging bag from spilling, the user often crosses the two handles and then ties them tightly to seal the bag opening. The handles will be deformed after being tied tightly, and under the action of the gravity of the items inside the packaging bag, the handles and the packaging bag body are likely to break, which is not conducive to people's use, and will also cause waste of packaging bags, and does not meet environmental protection requirements. Utility Model Content

[0005] In order to facilitate people to use packaging bags, reduce packaging bag waste and meet environmental protection requirements, the present application provides an environmentally friendly plastic packaging bag.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] An environmentally friendly plastic packaging bag comprises a packaging bag body, a fixing layer sleeved and fixedly arranged on the outer wall of the packaging bag body, and a drawstring located between the packaging bag body and the fixing layer. The drawstring is annular, and two annular openings of the fixing layer are both fixedly connected to the packaging bag body. A cavity for placing the drawstring is formed inside the packaging bag body and the fixing layer. The fixing layer has two openings for extending the drawstring symmetrically and spaced apart on one side close to the bag opening of the packaging bag body.

[0008] By adopting the above technical solution, when the environmentally friendly plastic packaging bag contains items and the drawstring is extended through the two openings and tied together, the user will not easily damage the bag opening of the environmentally friendly packaging bag during the process of tightening the drawstring. Compared with crossing the two handles and then tightening them, the drawstring can reduce the possibility of damage to the packaging bag, thereby improving the durability of the environmentally friendly plastic packaging bag and reducing its waste, thereby achieving the purpose of environmental protection.

[0009] Optionally, a reinforcing rib is formed on one side of the fixing layer close to the annular opening of the bag opening.

[0010] By adopting the above technical solution, the reinforcing ribs can improve the connection stability between the fixing layer and the bagging body.

[0011] Optionally, the edge of the fixing layer close to the bag opening is flush with the bag opening.

[0012] By adopting the above technical solution, the reinforcing ribs not only strengthen the packaging bag body and the fixed layer, but also reinforce the bag opening, so that the bag opening of the environmentally friendly packaging bag will not be easily damaged during the process of tightening the drawstring.

[0013] Optionally, another reinforcing rib is formed on the side of the fixing layer away from the annular opening of the bag opening.

[0014] By adopting the above technical solution, the connection stability between the packaging bag body and the fixing layer is further enhanced.

[0015] Optionally, the fixing layer is made of flexible material.

[0016] By adopting the above technical solution, it is convenient to form reinforcing ribs at the hot pressing position between the fixing layer and the bagging body.

[0017] Optionally, a hanging portion is integrally formed on the packaging bag body, a hanging hole is formed between the hanging portion and the packaging bag body, and an easy-tear line is formed on the hanging portion.

[0018] By adopting the above technical solution, a user can insert a rope into the hanging hole, or set the hanging hole on a nail fixed to the wall, thereby facilitating the storage of a large number of stacked environmentally friendly plastic packaging bags. When the user pulls the environmentally friendly plastic packaging bag, the rope or nail in the hanging hole separates the hanging part into two parts at the tear line, making it easier for the user to take it out.

[0019] Optionally, the hanging portion is located at the bag opening of the packaging bag body, the hanging portion is connected to the reinforcing rib, and the easy tear line is located on the side of the hanging portion away from the bag opening.

[0020] Optionally, two first fold lines and one second fold line are formed on one surface of the packaging bag body when it is laid flat, the length direction of the first fold line is perpendicular to the direction of the bag opening, and the two first fold lines are arranged at intervals and are respectively located on both sides of the packaging bag body, the length direction of the second fold line is perpendicular to the length direction of the first fold line, and the second fold line is close to the bottom of the packaging bag and is spaced apart from the bottom.

[0021] Optionally, the packaging bag body has the same outer wall and is located between two first fold lines to form a main body wall, a side wall is formed between the two main body walls, a third fold line is formed on the side wall, and three third fold lines are formed on the same side wall, and the three fold lines are radially distributed.

[0022] In summary, this application has the following technical effects:

[0023] 1. By arranging the packaging bag body, the fixing layer, the drawstring, and the opening, when the environmentally friendly plastic packaging bag is filled with articles and the drawstring is extended through the two openings and tied together, the user will not easily damage the bag opening when tightening the drawstring. The drawstring can reduce the possibility of damage to the packaging bag, thereby improving the durability of the environmentally friendly plastic packaging bag and reducing waste, thereby achieving the purpose of environmental protection;

[0024] 2. By setting up reinforcing ribs, the connection stability between the fixed layer and the bagging body can be improved;

[0025] 3. The fixing layer is made of flexible material, so that reinforcing ribs can be formed at the hot pressing position between the fixing layer and the bagging body. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present application is further described in detail below with reference to the accompanying drawings.

[0031] The present application discloses an environmentally friendly plastic packaging bag. Figure 1 The plastic packaging bag comprises a packaging bag body 1, one end of which is sealed by heat pressing to form a bag bottom, and the other end of which forms a bag opening. The bag body 1 comprises two main body walls 11, two side walls 12 integrally formed with the two main body walls 11, and two handles 13 integrally formed with the main body walls 11. The two handles 13 are located at the edge of the bag opening and are symmetrically distributed on both sides of the bag opening along the length direction.

[0032] Combine Figure 1 and Figure 2 When the bagging body 1 is laid flat, two mutually parallel first fold lines 14 are symmetrically formed on the main wall 11. The length of the first fold lines 14 is parallel to the direction of the bag opening, thereby forming two oppositely disposed side walls 12 of the bagging body 1. When the bagging body 1 is laid flat, a second fold line 15 is formed on the main wall 11. The second fold line 15 is close to the bag bottom and away from the bag opening. The length of the second fold line 15 is perpendicular to the length of the first fold line 14. After the first fold line 14 and the second fold line 15 are bent, the bottom of the bagging body 1 can form a flat bottom surface. When the bag is used to hold relatively regular-shaped items, the internal storage space of the bag can be better utilized. Compared with bags with irregular bottom shapes, wrinkles on the bottom can be reduced, which can cause uneven stress on the bagging body 1 and deformation. This reduces the possibility of damage to the bagging body 1 due to uneven stress, improves the durability of the bagging body 1, and increases its utilization rate, reducing waste of the bagging body 1, thereby achieving environmental protection.

[0033] Combine Figure 1 and Figure 2 A third fold line 16 is formed on the side wall 12. Three third fold lines 16 are formed on the same side wall 12, and are radially distributed. The length of the third fold line 16, which is farther from the bottom of the bag, is parallel to the length of the first fold line 14 and is located at the midline of the side wall 12. When the environmentally friendly plastic packaging bag is not in use and is being stored, the side wall 12 can be folded in half along the third fold line 16, with the folded edge placed inside the bag. This prevents the side wall 12 from forming new folds, facilitating orderly storage of the environmentally friendly plastic packaging bag.

[0034] Combine Figure 2 and Figure 3 The environmentally friendly plastic packaging bag also includes two hanging parts 2 integrally formed with the main body wall 11. The two hanging parts 2 are symmetrically arranged on the two main body walls 11, and the hanging parts 2 are located at the edge of the bag opening.

[0035] Reference Figure 3The hanging portion 2 is U-shaped, with the U-shaped opening facing the bag opening. A hanging hole 21 is formed between the hanging portion 2 and the edge of the bag opening. The user inserts a rope into the hanging hole 21, or sets the hanging hole 21 on a nail fixed to the wall, thereby facilitating the storage of a large number of stacked environmentally friendly plastic packaging bags for future use. A tear line 22 is formed on the side of the hanging portion 2 away from the bag opening. The tear line 22 is located in the middle of the hanging portion 2, and the length direction of the tear line 22 is parallel to the direction of the bag opening. When the user pulls the environmentally friendly plastic packaging bag with force, the rope or nail in the hanging hole 21 separates the hanging portion 2 into two parts at the tear line 22, making it easier for the user to take it out.

[0036] The hanging part 2 is integrally formed with the bagging body 1. After the environmentally friendly plastic packaging bag is taken out, the hanging part 2 will not separate from the bagging body 1. Compared with the separate design of the hanging part 2 and the bagging body 1, it can effectively reduce the possibility of the hanging part 2 causing pollution to the environment, and further improve the environmental friendliness of the environmentally friendly plastic packaging bag.

[0037] Combine Figure 2 and Figure 3 The environmentally friendly plastic packaging bag also includes a fixing layer 3 fixedly mounted on the outside of the bagging body 1. The fixing layer 3 is annular and is sleeved onto the outer wall of the bagging body 1. The fixing layer 3 is positioned near the bag opening, and its edge near the bag opening is flush with the bag opening. The two annular edges of the fixing layer 3 are fixedly connected to the outer wall of the bagging body 1 through heat pressing, forming a cavity between the fixing layer 3 and the outer wall of the bagging body 1. A ring-shaped drawstring 4 is disposed within the cavity.

[0038] Combine Figure 2 and Figure 3 The fixing layer 3 is made of a flexible material such as rubber or thermoplastic plastic, so that a reinforcing rib 5 is formed at the hot pressing point between the fixing layer 3 and the bagging body 1, and the hanging part 2 is connected to the reinforcing rib 5. An opening 6 for the drawstring 4 to extend out is reserved at the edge of the fixing layer 3 flush with the bag opening. Two openings 6 are provided and the two openings 6 are symmetrically distributed on the bag opening. In this embodiment, the two openings 6 are respectively located in the two hanging holes 21. The reinforcing rib 5 can not only improve the connection stability between the fixing layer 3 and the bagging body 1, but also strengthen the bag opening. When the environmentally friendly plastic packaging bag contains items and the drawstring 4 is extended through the two openings 6 and tied together, the user will not easily damage the bag opening of the environmentally friendly packaging bag during the process of tightening the drawstring 4. Under the action of the weight of the items, the reinforcing rib 5 can also effectively reduce the stretching of the bag opening by gravity, reduce the possibility of damage to the packaging bag, thereby improving the durability of the environmentally friendly plastic packaging bag and reducing its waste, thereby achieving the purpose of environmental protection.

[0039] 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.
