[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] A type of packaging bag that can be opened multiple times, such as Figure 1 , Figure 2 as well as Figure 3 As shown, the bag includes a bag body 1, one side of which is folded to form an opening, and a sealing structure that can be opened and closed multiple times is provided between the folded part 2 and the bag body 1.
[0017] Specifically, the sealing structure mainly includes the dotted tear 3, the adhesive strip 4, and the easy-to-stick part 5.
[0018] The dotted tear line 3 is located at the connection between the folded part 2 and the bag body 1 to form an opening. When opening the packaging for the first time, the user needs to tear along this dotted tear line 3 to form the initial opening for taking out items.
[0019] The adhesive strip 4 is folded and disposed inside the folded part 2. The adhesive strip 4 is a strip structure with one side coated with pressure-sensitive adhesive. The pressure-sensitive adhesive surface is covered with an anti-adhesive strip 6 to prevent the adhesive strip 4 from losing its adhesiveness accidentally during transportation and storage. The two ends of the anti-adhesive strip 6 extend outward from the adhesive strip 4 to form a handle part 61 that is easy for the user to pinch and tear off.
[0020] The easy-to-adhesive part 5 is fixedly set on the outer surface of the bag body 1 and located near the dotted tear opening 3. The easy-to-adhesive part 5 is a smooth area, specifically made of BOPP material. Its surface is extremely smooth and flat, and it has good affinity with pressure-sensitive adhesive, providing excellent initial tack and repeated bonding performance, making it easy to connect. This area cooperates with the pressure-sensitive adhesive surface on the adhesive strip 4 to provide a good adhesion effect.
[0021] To ensure that the adhesive strip 4 can be accurately folded and attached to the easy-to-stick part 5, a pre-compression crease is provided at the connection between the adhesive strip 4 and the folding part 2. This pre-compression crease makes the folding action smoother and the position more accurate.
[0022] In addition, a labeling area 7 is provided on the outer surface of the bag body 1. This labeling area 7 clearly indicates to the user how to operate the sealing structure by printing text or graphics, so as to improve the user experience.
[0023] In this embodiment, the bag body 1 and the folding part 2 are integrally formed from composite packaging material. Specifically, the composite packaging material is composed of BOPP and CPP. CPP has high heat-sealing strength and transparency. When combined with BOPP, it is suitable for packaging scenarios that require high-temperature sterilization and is a common material used to make sanitary napkin packaging.
[0024] Practical effect: When used for the first time, the product is opened through the dotted tear 3, which ensures the initial sealing of the product. After opening, the adhesive strip 4 and the easy-to-stick part 5 can be used to achieve repeated sealing of the packaging bag, effectively isolating air, moisture and contaminants, and ensuring the cleanliness and dryness of the remaining sanitary napkins in the bag.
