Description
Technical Field
[0001] The present application relates to the field of packaging bags, and in particular to a packaging bag with a middle sealed edge and an easy-tear opening. Background Art
[0002] With the development of diversified commodity packaging, the practicality and aesthetics of packaging bags are increasingly valued. Existing packaging bags are usually sealed by sealing edges, but when opening, tools such as scissors or knives are often needed, which is inconvenient to operate and poses safety hazards.
[0003] In addition, the existing packaging bags usually have easy-tear openings at both ends of the packaging bags, and the easy-tear openings of the middle-sealed bags are also set at both ends of the bag body. When the packaging bag is torn open through the easy-tear opening, the packaging bag will be torn into two parts. This easy-tear opening design has two problems: on the one hand, it will increase the difficulty of recycling; on the other hand, the torn edge of the packaging bag needs to be discarded before the items in the bag can be taken out and used normally, which brings inconvenience to consumers. Therefore, the development of a packaging bag that is easy to open and maintains sealing has become an urgent need in the market.
[0004] Chinese Patent ZL202022481807.5 A tear-away packaging bag provides an tear-away packaging bag, and an tear line is arranged on the outer surface of the bag body. On the one hand, the bag body can be easily torn at the tear line and the tearing edge can be kept neat and beautiful; on the other hand, when tearing, it will only be torn along the direction of the tear line to prevent the objects in the bag from scattering. In order to facilitate the resealing of the packaging bag, the utility model also arranges a seal on the surface of the bag body to facilitate the secondary sealing of unused products. It can be opened repeatedly, and the operation is simple, which increases the practicality of the packaging bag. However, this patent still has the problem that the tear line falls off and becomes waste, affecting environmental hygiene.
[0005] Chinese patent ZL201520160350.4 discloses a tear-free bag that can be opened as a whole without tear strips. By adopting the tear-line structure and cooperating with the sealing edge and the folding edge to open the tear line, the bag opening process becomes easy and simple, and the bag will not produce waste such as tear strips after opening, making it more convenient to use. However, this utility model patent has problems such as complex structure and high production cost. Utility Model Content
[0006] In order to solve the problem that packaging bags in the background technology generate tear strip waste and have high production costs, the present application provides a middle-sealed edge easy-tear packaging bag, which is a whole after opening and does not generate bag material waste.
[0007] The present application provides a middle-sealed edge easy-tear packaging bag, which adopts the following technical solution:
[0008] A packaging bag with a middle sealed edge and an easy tear opening comprises a bag body, a bag opening sealing edge, a middle sealed edge, an easy tear opening, and a side sealed edge. The bag opening sealing edges are arranged at the upper and lower ends of the bag body, and are used to seal the bag opening and maintain the sealing of the bag body. The middle sealed edge is located on the back of the packaging bag and in the middle of the back, and the length of the middle sealed edge is the same as the length of the bag body.
[0009] Furthermore, at least one easy-tear notch is provided on the middle sealing edge, and a sawtooth is provided at the easy-tear notch with an inclination angle of 30-60 degrees with the middle sealing edge. The sawtooth tearing design improves the efficiency of opening the packaging bag, allowing the user to easily tear the packaging bag while ensuring the integrity of the packaging bag. The distance between the easy-tear notch and the sealing edge of the bag opening is greater than 1 cm to avoid accidental touching or tearing.
[0010] Furthermore, the edge of the bag body corresponding to the easy-tear opening is provided with a side sealing edge; the side sealing edge and the bag opening sealing edge are in a concave shape or are independently distributed; when the bag body is relatively wide, the side sealing edge may not be provided. The side sealing edge improves the overall firmness of the packaging bag after it is torn open, avoids disintegration, enhances the practicality of the packaging bag, and improves the aesthetics of the packaging bag.
[0011] Furthermore, the tear-off opening is located near the bag opening on the middle sealing edge, or in the middle of the middle sealing edge, or in the upper part of the middle sealing edge. The distribution position of the tear-off opening on the middle sealing edge of the packaging bag is determined according to the items in the packaging bag. For three-dimensional items, the tear-off opening is close to the opening of the packaging bag; for granular items, the tear-off opening is close to the middle of the packaging bag; for sheet items, the tear-off opening is close to the upper part of the items. When the packaging bag is opened, a part of the sheet item can be partially exposed for easy removal. This design allows the packaging bag to be customized according to different usage scenarios to meet the needs of different users.
[0012] Furthermore, the bag body of the packaging bag is a sealed packaging bag, which can be in an inflated form or a vacuum form to extend the shelf life of the contents of the packaging bag.
[0013] Furthermore, the bag body is a small-sized packaging bag, with a length of 3 cm to 50 cm and a width of 2 cm to 30 cm. This structure is more suitable for use on small packaging bags.
[0014] In summary, the present application includes at least the following beneficial technical effects:
[0015] By setting an easy-tear notch on the middle seal edge of the middle-sealed packaging bag, the bag can remain intact after opening, which is conducive to the recycling of the packaging bag. After opening the bag, the items in the bag can be taken out directly, eliminating the traditional step of opening the packaging bag and discarding the torn part of the packaging bag. It is more in line with user consumption habits, easy to use, and more conducive to maintaining environmental hygiene.
[0016] The design of the side sealing edge further enhances the practicality and aesthetics of the packaging bag. The packaging bag is suitable for sealing packaging needs of various sizes and shapes, especially for small packaging bags, such as small packaging products such as food and cosmetics.
