Description

A wet wipes packaging bag

Technical Field

The utility model relates to the technical field of packaging bags, in particular to a wet wipes packaging bag.

Background Art

At present, Chinese patent application number: CN201820544601.2 discloses a wet tissue packaging body, including a first packaging body, one side of the first packaging body is provided with an incision, the incision is covered with a first structure for opening or sealing the incision, a plurality of second packaging bodies are stacked in the first packaging body, and the second packaging body is used to seal and contain wet tissues, and discloses a packaging bag of an existing general structure;

In order to facilitate consumers to extract and use the existing multi-piece wet wipes, an extraction port is opened on the packaging film (packaging bag), and a reusable opening adhesive sticker is affixed to ensure the hygiene of the wet wipes after opening. The conventional wet wipe opening adhesive sticker is made of PP composite paper, and a removable adhesive is coated on the adhesive surface of the packaging film. The material thickness is 12 to 15 filaments. In order to prevent the wet wipes product from leaking at the extraction port during transportation and handling, the peeling force of the adhesive sticker is relatively high, generally designed to be 700 to 900gf (standard steel plate). When consumers open it for the first time, it is sometimes difficult to tear it open. In order to facilitate the tearing and use of the adhesive sticker, an easy-to-tear virtual tangent line is generally made on both sides of the adhesive sticker close to the box cover. Reference can be made to Chinese patent application number: CN201621176404.7, which discloses a new type of anti-leakage wet wipes box, which discloses easy tearing through two dotted perforated lines;

However, in order to prevent the liquid from the wet wipes from seeping out from the tear line, the tear line must be at least 5mm away from the edge of the opening, which means that the tear line must be close to the hollow edge of the box lid. Due to the accuracy of the lid-sticking machine, the box lid often presses against the tear line of the opening adhesive, resulting in a poor user experience for consumers.

Utility Model Content

Therefore, in view of the above problems, the utility model proposes a wet wipes packaging bag, which solves the technical problem that the existing tear line is close to the hollow edge of the box cover, and the box cover often presses the tear line of the opening adhesive, resulting in a poor user experience for consumers.

DETAILED DESCRIPTION

The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

1 to 7 , the present embodiment provides a wet wipes packaging bag, comprising a bag body 1, an opening 2 provided on the top surface of the bag body 1, a sticker 3 adhered to the opening 2, and a covering mechanism for covering the position of the sticker 3, wherein one side of the sticker 3 is provided with a tearing portion 3a that is not adhered to the bag body 1, and the sticker 3 is provided with two transversely arranged reserved cuts 3b near the tearing portion 3a, and the sticker 3 comprises a plurality of PE layers 30a and a plurality of PP layers 30b, wherein at least two of the PP layers 30b are arranged between the PE layers 30a.

The adhesive label is made of a blend of PE layer and PP layer using a multi-layer co-extrusion process as the material of the wet wipe opening adhesive label, and is coated with removable glue at the same time; the material has a greatly improved softness compared to the existing conventional PP adhesive paper, and at the same time has good adherence to the wet wipe packaging material, so the peeling force of the adhesive label is adjusted to 500-600gf to meet the anti-leakage problem of the wet wipes, and at the same time, the material has good tearability, and only needs to open the front end knife edge to tear it continuously, smoothly and parallel, without the need for continuous point-break tear lines, which effectively improves the consumer's opening experience. Please refer to Figures 2 and 3, Figure 2 is the existing continuous point-break tear line, and Figure 3 is the wet wipes packaging bag of this application. The adhesive label has a reserved knife edge near the tearing portion, and it can be torn continuously and smoothly by tearing back along the tearing portion.

The PE layer and PP layer of the utility model adhesive tape preferably adopt a seven-layer co-extrusion process as the material of the wet wipes opening adhesive tape, and the material thickness is 900-1000μ, of which the PP layer 30b is respectively in the third and fifth layers, and the thickness of each PP layer and PE layer is 100-200μ, of which at least two PP layers 30b are located between the PE layers 30a. The removable adhesive is coated on the contact surface with the wet wipes film. The softness of this material is greatly improved compared with the conventional PP adhesive tape. At the same time, it has good adhesion similar to the wet wipes packaging material. The peeling force of the adhesive tape is adjusted to 500-600gf to meet the anti-leakage problem of wet wipes, effectively improving the consumer's experience;

At the same time, the PE layer and PP layer multi-layer co-blended co-extruded process adhesive tape has good tearability. It can be torn continuously and smoothly by just opening the reserved knife edge at the front end. There is no need to continuously break the tear line, which effectively improves the consumer's opening experience.

The adhesive material used in this utility model is much softer than conventional PP-layer adhesive. The labeling mechanism of the equipment is separated from the peeling plate and reinforced with a brush after labeling. The label is prone to wrinkles, channels, and even bristles in the label. After research, the silicone guide wheel was chosen to improve it. After the improvement, the silicone guide wheel can apply the label separated from the base paper more evenly and flatly to the surface of the wet wipes packaging material. The label is accurately pasted in the position without wrinkles, channels, etc.

Compared with the traditional PP layer adhesive tape, since the PP layer adhesive tape needs to open a dotted perforation line between the opening and the capping mechanism, the dotted perforation line needs to be kept at a greater distance from the opening to avoid being squeezed during logistics transportation and the bag body leaking from the dotted perforation line position.

The length of the reserved blade 3b can be set according to actual usage. The length of the reserved blade is usually the length distance between the tearing part and the opening. The length range of the reserved blade is 1mm to 100mm. The optimal length distance is 1mm to 10mm. The actual size of the reserved blade of the product is about 2mm. It can be adjusted according to the actual product size and is not limited to the above size.

Refer to Figure 2. The dotted perforated line 3' needs to be horizontally covered with adhesive tape and requires perforated breakpoints. Refer to Figure 3, only a 1mm to 10mm incision is required to be torn off. The adhesive tape can be made of Denison SR106 model flexible film, or existing adhesive tapes with the same function, leaving a 1mm to 10mm incision for horizontal smooth tearing.

The tearing portion 3a is pulled to the right. Since the reserved knife edge 3b is short, the adhesive sticker 3 can be torn apart horizontally through the reserved knife edge 3b. Compared with the traditional method of making a long horizontal reserved knife edge 3b, the sealing is better and it is easier to tear. Compared with part of the adhesive sticker 3 directly adhered to the top surface of the bag body 1 and pressed by the covering mechanism, when the adhesive sticker 3 is pulled hard, the two sides of the adhesive sticker 3 are blocked by the covering mechanism and pulled apart, which is more labor-saving and easy.

The adhesive tape 3 is provided with seven layers, the PP layer 30b is in the third and fifth layers, the PE layer 30a is in the first, second, fourth, sixth and seventh layers, and a co-extruded film is obtained. The adhesive tape formed by the co-extrusion of the PP layer and the PE layer has good versatility and is easy to tear when used. In actual use, it is not limited to seven layers, and only the PP layer and the PE layer in the middle layer need to be adjacent to each other. The material layers other than the first and seventh layers can be adjusted according to actual use conditions.

The thickness of the PP layer 30b is 100-200μ, the thickness of the PE layer 30a is 100-200μ, the peeling force of the adhesive tape is 500-600gf, and the thickness of the adhesive tape material after multi-layer co-extrusion is 6.6-8.6C. At the same time, the total thickness after coating with removable glue is 9-10C. The material is much softer than conventional PP adhesive paper and has good tearability. At the same time, it has good adhesion similar to the wet wipes packaging material. During the test, the PP composite paper is glued to the opening position of the top surface of the bag body, and the adhesive tape blended with the PE layer and the PP layer is glued to the opening position of the top surface of the bag body, and is torn from the same tearing portion. Therefore, the peeling force of the adhesive tape is adjusted to 500-600gf to meet the anti-leakage problem of the wet wipes, and the tearing is more parallel and smooth.

The forming process of the bag body is as follows: in the first step, a multi-layer PE layer and a multi-layer PP layer are co-extruded by an extruder to obtain a co-extruded film, and then one side of the co-extruded film is coated with glue and a backing paper is pasted, and then the co-extruded film is provided with reserved cutting edges at intervals according to the length of the capping mechanism to obtain a sticker;

The second step is to input the envelope and open an opening in the envelope;

In the third step, the adhesive label is input, flattened and laminated at the opening position of the film through the silicone guide wheel 1a, and the base paper is recovered through the output roller 1b.

The fourth step is to cut the film into pieces and transport them in small packages.

The fifth step is to input the capping mechanism, transfer the capping mechanism to the gluing position on the small package, and output it.

The multi-layer co-extrusion technology and the extruder are conventional technologies in the art and will not be described in detail here.

The adhesive material used in this utility model is much softer than conventional PP glued paper. The labeling mechanism of the equipment is separated from the peeling plate and reinforced with a brush after labeling. The label is prone to wrinkles, channels, and even bristles in the label. After research, the silicone guide wheel was chosen to improve it. After the improvement, the silicone guide wheel can apply the label separated from the base paper more evenly and flatly to the surface of the wet wipes packaging material. The label is accurately pasted in the position without wrinkles, channels, etc.

In conventional wet wipes packaging, the tear line is required to be more than 5mm away from the edge of the opening. However, due to the volume of the bag, the size of the capping mechanism cannot be enlarged. After 5mm away from the edge of the opening, the dotted perforated line will be close to the edge of the inner side of the capping mechanism that is not laminated with the top surface of the bag. In high-speed production lines, due to the accuracy of the capping machine equipment, the capping mechanism often presses the position of the dotted perforated line of the adhesive label, making it difficult to tear off the adhesive label. Compared with the traditional dotted perforated line, the adhesive label of this material has a reserved knife edge, which does not require two long dotted perforated lines. It only needs to be pre-cut in the tearing part. A reserved blade is provided, which can be torn parallel and smoothly. Since there is no dotted line punching, the reserved blade can be close to the opening on the top surface of the bag body, and better sealing performance can be achieved for the opening position. Since the reserved blade is close to the opening on the top surface of the bag body, the reserved blade can be set at a far distance from the covering mechanism to avoid the covering mechanism pressing the reserved blade, thereby improving the sealing of the wet wipes during logistics transportation and improving the tearability of the adhesive label. The covering accuracy of the covering machine and the bag body is reduced during the production process, and the covering machine is prevented from pressing the covering mechanism to the tear line position of the opening adhesive label.

The covering mechanism includes an outer ring 41, an inner concave ring 42 arranged in the middle of the outer ring 41, a raised portion 43 arranged on the inner edge of the inner concave ring 42, a cover body 44 for covering the inner concave position, an outer buckle portion 45 arranged on the outer side of the raised portion 43, an inner ring portion 46 extending to the bottom of the cover body 44, and an outer convex portion 47 arranged on the inner ring portion 46 and buckled with the outer buckle portion 45. A pull plate 48 is provided on the side of the outer ring 41 close to the outer buckle portion 45. The cover body 44 is provided on one side of the outer ring 41. The outer ring 41 is provided on the top surface of the bag body 1, and the outer ring 41 surrounds the adhesive tape 3.

Through the setting of the covering mechanism, when it is necessary to open the cover body, pull upwards from the pull plate position with your fingers, the cover body will be separated from the outer ring, the cover body leaves the inner concave ring position, and the inner ring part and the raised part are pulled upwards a distance, after the cover body is opened, the adhesive label can be directly torn off from the inner circle position of the raised part for use, and when it is necessary to buckle, the cover body is covered on the inner concave of the outer ring, and then the outer convex part on the inner ring part will buckle on the outside of the outer buckle part on the raised part, the raised part and the inner ring part can form a first sealing space through buckling, and the cover body is covered on the inner concave ring position, the inner concave ring position can be sealed and covered to form an internal space with good sealing performance, so as to prevent the problem of pressure leakage of the packaging bag, and the height of the outer ring is greater than the height when the cover body is covered on the inner concave ring position, the covering mechanism is subjected to pressure, the outer ring will withstand the external pressure, so as to avoid the problem of easy cracking of the cover body under pressure.

One side of the adhesive tape 3 is provided with a tearing portion 3a which is not adhered to the bag body 1, and the adhesive tape 3 is provided with two transverse reserved cuts 3b near the tearing portion 3a. The cut length is 1mm to 100mm, and the optimal length is 1mm to 10mm.

Refer to Figure 4. The dotted perforated line 3' needs to be horizontally covered with a reserved incision that covers the horizontal length of the adhesive tape. Refer to Figure 5. Only a reserved incision of 1mm to 10mm is required to be torn off. The adhesive tape is made of Denison SR106 model flexible film, a satin matte white polyolefin film, and a reserved incision of 1mm to 10mm is required to be torn off horizontally and smoothly.

The tear portion 3a is pulled to the right. Since the length of the reserved incision 3b is 1mm to 10mm, and the reserved incision 3b does not occupy more than one-third of the length of the tear portion 3a, the adhesive sticker 3 can be torn apart horizontally through the reserved incision 3b. Compared with the traditional method of making a long horizontal reserved incision 3b, the sealing is better. Part of the adhesive sticker 3 is directly adhered to the top surface of the bag body 1 through the outer ring 41. When the adhesive sticker 3 is pulled hard, the two sides of the adhesive sticker 3 are blocked by the raised portion 43 and pulled apart. This method is laborious.

A sealing strip 51 is provided on the outer side of the inner ring portion 46, and a raised portion 52 is provided in the middle of the sealing strip 51. The setting of the sealing strip, wherein the sealing strip is surrounded and arranged on the outer side of the inner ring portion, can reduce the gap between the inner ring portion and the raised portion and improve the sealing performance of the covering mechanism. The setting of the raised portion, wherein the sealing strip is located in the raised portion and has an O-shaped hollow portion 5a. Under the action of the O-shaped hollow portion, the sealing strip bulges at the position of the raised portion. When the covering mechanism is covered, the raised portion can be compressed and flattened due to the O-shaped hollow portion inside. When the cover body is buckled, the raised portion will expand outwards under the action of elasticity to fill the gap between the inner ring portion and the raised portion, thereby improving the problem that the cover body is difficult to cover. A convex ridge 5b that can be inserted into the O-shaped hollow portion is provided on the inner ring portion to facilitate the fixing of the sealing strip and prevent the sealing strip from falling off easily during the process of opening and closing the cover.

The raised portion 52 and the sealing strip 51 have a smooth transition, and a plurality of grooves 53 are provided on the raised portion 52. The grooves on the raised portion can increase the anti-slip performance of the sealing strip and further prevent the sealing strip from falling off easily.
