[0001] This utility model relates to the field of packaging technology, and more specifically, to a wet wipe opening sticker with tear-resistant effect. Background Technology

[0002] A wet wipes opener's seal is a security seal specifically designed for wet wipes packaging to prevent damage and drying of the wipes before opening. It is typically made of high-strength self-adhesive material with excellent toughness and tear resistance, effectively protecting the integrity of the wet wipes.

[0003] In terms of usage, consumers can easily remove the wipes by simply tearing off the opening sticker. These opening stickers are typically designed with easy-to-use features such as zippers or snaps in mind, ensuring a smooth and convenient opening process and enhancing the user experience.

[0004] Wet wipe opening stickers are widely used in various fields such as medical care, baby care, and cleaning products, providing consumers with a safe and convenient way to use them. However, in daily sales, traditional wet wipe opening stickers may be torn open on the shelf, and consumers removing or putting the wipes back often affects the resale of the product. This issue urgently needs attention and solutions to maintain the product's market value and the consumer's purchasing experience.

[0005] Based on this, the present invention designs a wet wipe opening sticker with tear-resistant effect to solve the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this invention is to provide a wet wipe opening sticker with tear-resistant effect to solve the problems mentioned in the background art.

[0008] 2. Technical Solution

[0009] A tear-resistant wet wipe opening sticker includes a wet wipe bag, with an opening sticker on the top of the wet wipe bag, an adhesive removal area on the right side of the opening sticker, and a damage prevention area connected to the right side of the adhesive removal area by a dotted break line.

[0010] Preferably, the left edge of the opening sticker is fixedly bonded to the left edge of the top of the wet wipes bag, and the bonding length between the opening sticker and the wet wipes bag accounts for 1 / 3 of the total length of the top of the wet wipes bag.

[0011] Preferably, the adhesive removal area is an adhesive-free structure, the width of the adhesive removal area is 1-2cm, and the upper surface of the adhesive removal area is printed with markings to indicate the tearing position.

[0016] Preferably, the width of the damage prevention area is 0.8-1 times the width of the adhesive removal area, and the lower surface of the damage prevention area is not provided with an adhesive layer.

[0017] 3. Beneficial effects

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1) In this utility model, the newly designed opening sticker is an integral structure when it leaves the factory. The tearing position is limited by the dot break line, and the breaking tensile value of the dot break line is controlled at 5-8N. This can effectively prevent users from accidentally tearing the opening sticker before purchasing, avoiding premature damage to the packaging and causing the wipes to become damp and contaminated. At the same time, it is lower than the normal tearing force of an adult, so it does not affect normal opening after purchase. Structurally, it ensures the integrity of the product from leaving the factory to before use.

[0020] 2) In this utility model, the combination design of the adhesive removal area and the anti-damage area greatly improves the ease of use and durability of the opening patch. The adhesive removal area is a 1-2cm wide adhesive-free structure and is printed with tear marks, allowing users to accurately locate the tearing position and avoid hand slippage or deformation of the opening patch due to adhesive layer adhesion. On the other hand, the thickness of the anti-damage area is 1.2-1.5 times that of the main body of the opening patch, and the right edge is a rounded transition structure, which not only enhances the strength of the force when tearing and prevents the opening patch from breaking due to excessive local force, but also avoids sharp edges from scratching the hands. At the same time, the lower surface of the anti-damage area has no adhesive layer, so it can be repeatedly folded and stored without affecting the subsequent sealing function of the opening patch.

[0021] 3) In summary, without adding new complex structures, this utility model solves the problems of easy accidental tearing, easy breakage, and poor sealing after repeated use of existing wet wipe opening stickers through the coordinated design of point breakage line to prevent accidental tearing, easy positioning of adhesive removal area, anti-breakage area and weather resistance of PET material. It also takes into account the convenience of production, has a wide range of applications, and can be adapted to the packaging needs of different scenarios such as baby wipes, medical wipes, and industrial cleaning wipes.

[0023] Figure 2 This is a schematic diagram of the opening sticker structure of this utility model.

[0024] The labels in the diagram are as follows: 1. Wet wipe bag; 2. Opening sticker; 3. Dotted line; 4. Damage prevention area; 5. Adhesive removal area. Detailed Implementation

[0025] Example: Please refer to Figure 1-2 A tear-resistant wet wipe opening sticker includes a wet wipe bag 1, an opening sticker 2 at the top of the wet wipe bag 1, and an adhesive removal area 5 on the right side of the opening sticker 2. A damage prevention area 4 is connected to the right side of the adhesive removal area 5 via a dotted break line 3. The left edge of the opening sticker 2 is fixedly adhered to the left edge of the top of the wet wipe bag 1, and the adhesive length between the opening sticker 2 and the wet wipe bag 1 accounts for 1 / 3 of the total length of the top of the wet wipe bag 1. The adhesive removal area 5 is a non-adhesive structure, with a width of 1-2 cm, and its upper surface is printed with markings indicating the tear position. The dotted break line 3 extends horizontally along the connection between the adhesive removal area 5 and the damage prevention area 4, and its breaking tensile strength is 5-8 N. The thickness of the damage prevention area 4 is 1.2-1.5 times the thickness of the main body of the opening sticker 2, and the right edge of the damage prevention area 4 has a rounded transition structure. The main body of the opening sticker 2 is made of PET polyester film, and the lower surface of the opening sticker 2 has removable pressure-sensitive adhesive only in the areas other than the adhesive removal area 5 and the non-damage prevention area 4. The adhesive removal area 5 and the main body of the opening sticker 2 are integrally molded, and the length of the adhesive removal area 5 is the same as the width of the main body of the opening sticker 2. The width of the damage prevention area 4 is 0.8-1 times the width of the adhesive removal area 5, and the lower surface of the damage prevention area 4 has no adhesive layer.

[0026] Adhesive Fixation: The left edge of the opening sticker 2 is fixed to the top left edge of the wet wipe bag 1 by heat pressing. The adhesive width is 1 / 6-1 / 8 of the total width of the opening sticker 2 (for example, when the opening sticker is 3cm wide, the adhesive width is 0.5cm). The width ratio is controlled to ensure a firm connection. The adhesive length between the opening sticker 2 and the wet wipe bag 1 is 1 / 3 of the total top length of the wet wipe bag 1 (for example, when the total top length of the wet wipe bag is 9cm, the adhesive length is 3cm). This avoids the opening sticker from falling off due to the adhesive area being too small, and also leaves an opening space of 2 / 3 of the total top length of the wet wipe bag 1 for taking out the wet wipes after opening. This ratio is suitable for the operation habit of adults to take out the wipes with one finger, ensuring that hand movement is not restricted when taking out the wipes.

[0027] Adhesive Removal Area Design: Adhesive removal area 5 is an adhesive-free structure, with a width of 1 / 2 to 2 / 5 of the total width of the opening sticker 2 (for example, when the opening sticker is 3cm wide, the adhesive removal area is 1.2-1.5cm wide). This proportional extension, within the preferred range of 1-2cm, adapts to the design requirements of opening stickers of different widths. The upper surface is screen-printed with the words "Tear Area" in red and an arrow mark in Song typeface, which is highly recognizable against the white PET substrate and can quickly guide users to locate the tear position. At the same time, the thickness of adhesive removal area 5 is consistent with the thickness of the main body of opening sticker 2 (ratio of 1:1), ensuring a flat overall structure and avoiding bulges due to thickness differences, thus preventing structural damage caused by snagging during transportation.

[0028] Point breakage line parameters: Point breakage line 3 extends horizontally along the connection between the glue removal area 5 and the damage prevention area 4. It is processed by rotary die-cutting process, and the ratio of hole spacing to hole diameter is 2:1 (for example, when the hole spacing is 2mm, the hole diameter is 1mm). After tensile testing, its breaking tensile force value is stable in the preferred range of 5-8N. Combined with ergonomic design, when an adult pinches the damage prevention area 4 with their thumb and forefinger, the applied tensile force is 1.2-1.5 times the breaking tensile force value (i.e., 6-12N) to break the point breakage line. This tensile force ratio ensures both ease of opening and no obvious feeling of effort, and is suitable for users with different strengths.

[0029] Characteristics of the damage-resistant area: The thickness of the damage-resistant area 4 is 1.4 times the thickness of the main body of the opening patch 2 (within the preferred range of 1.2-1.5 times). It is made of double-layer composite PET polyester film, and its tear resistance is 60% higher than that of the main body of the opening patch (strength ratio of 1.6:1), effectively preventing the opening patch from breaking due to localized force concentration when tearing. In addition, the right edge of the damage-resistant area 4 is rounded and chamfered, with a radius of 1 / 4 of the width of the damage-resistant area 4 (for example, when the width of the damage-resistant area is 1.2cm, the radius of the rounded corner is 0.3cm). The proportional chamfering eliminates sharp edges and prevents scratches on the skin of the hands during use, making it especially suitable for scenarios with high safety requirements such as baby wipes and medical wipes. At the same time, the width of the damage-resistant area 4 is 0.8 times the width of the adhesive removal area 5 (within the preferred range of 0.8-1 times). This size ratio is suitable for the grip span of an adult's thumb and forefinger, further improving the comfort of operation.

[0030] Material and Adhesive Layer Distribution: The main body of the sealing patch 2 is made of food-grade PET polyester film. This material has a light transmittance of ≥90%, a temperature resistance range of -20℃ to 60℃, and can adapt to different storage environments. Its longitudinal tear strength is ≥8N. The lower surface of the sealing patch 2 is coated only in the non-adhesive removal area 5 and the non-damage prevention area 4 (i.e., the left adhesive area and the middle sealing area) with a removable pressure-sensitive adhesive specifically for wet wipes. The adhesive layer thickness is half the thickness of the main body of the sealing patch 2 (for example, if the main body thickness is 0.1mm, the adhesive layer thickness is 0.05mm). The adhesive layer has the characteristics of "moderate initial adhesion and no residue after repeated application". It has been tested and can be repeatedly applied more than 30 times. After application, the humidity retention rate inside the wet wipe bag is ≥85%. The adhesive removal area 5 and the main body of the opening sticker 2 are integrally die-cut and formed. The length ratio of the adhesive removal area 5 to the width of the main body of the opening sticker 2 is 2.5-3:1 (for example, when the main body is 3cm wide, the adhesive removal area is 8-10cm long). The length ratio ensures the overall structural symmetry and avoids deformation of the opening sticker due to uneven force during use.

[0031] Working principle of this utility model:

[0032] When a user uses the product for the first time after purchase, they can quickly locate the tearing position by following the "tear zone" marking on the adhesive removal area 5. Since the adhesive removal area 5 is adhesive-free, the user's hand will not slip due to the adhesive layer when pinching the protective area 4 with their thumb and forefinger, allowing for precise force application. When the applied pulling force reaches 5-8N, the point break line 3 breaks along the preset hole, separating the protective area 4 from the adhesive removal area 5. At this point, the user can continue to lift the opening sticker 2 to open the opening of the wet wipe bag 1 and take out the wet wipes inside. During the tearing process, the protective area 4, made of double-layer PET composite material (1.2-1.5 times the thickness of the main body of the opening sticker), has a much higher tear resistance than the main body of the opening sticker, and can withstand the concentrated force during tearing, preventing the opening sticker 2 from breaking. At the same time, the rounded transition structure on the right side of the protective area 4 can prevent sharp edges from scratching the hand during tearing, improving the safety of use.
