Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a honeycomb paper packaging bag. Background Technology

[0002] Most paper packaging bags currently on the market (such as document bags and express delivery bags) use the following structure, which has significant defects:

[0003] First, the cushioning structure is simple: traditional solutions rely on a single layer of corrugated paper or foam filling, which limits the compressive strength to one direction and is insufficient to cushion impacts from multiple angles (such as drops and squeezing), easily leading to damage to fragile items inside.

[0004] Secondly, it cannot be reused multiple times: ordinary adhesive seals can only be used once and cannot meet the needs of users to open and close them multiple times (such as document bags that need to be repeatedly stored and retrieved), resulting in a significant decrease in the sealing performance after resealing.

[0005] Finally, there is a conflict between logistics tracking and protection: existing RFID tags are usually affixed to the surface of the bag, which makes them prone to wear and tear and detachment. Utility Model Content

[0006] This invention provides a honeycomb paper packaging bag that can solve the problems mentioned in the background art.

[0007] This utility model provides a honeycomb paper packaging bag, comprising:

[0008] A bag that creates storage space;

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Example:

[0033] like Figures 1 to 6 As shown, this application provides a honeycomb paper packaging bag, including: a bag body 10 forming a storage space; a connecting area 20 located at the top of the bag body 10, with two sets of adhesive layers 30 disposed on one side of the connecting area 20, and release paper 40 attached to the outer side of the adhesive layers 30; the bag body 10 includes an outer layer 11 and an inner layer 12, and a honeycomb paper 50 is disposed in the middle of the inner layer 12 and the outer layer 11; an RFID tag 70 is placed in the middle of the honeycomb paper 50;

[0034] The length of the honeycomb paper 50 can be adaptively adjusted according to the lengths of the outer layer 11 and the inner layer 12;

[0035] The connecting area 20 forms an integral structure with one side of the bag opening of the bag body 10, and the connecting area 20 is a rectangular structure, which facilitates sealing the bag opening.

[0036] By adopting the above technical solutions, through the setting of honeycomb paper 50, bag body 10, adhesive layer 30, release paper 40 and RFID tag 70, the existing packaging bags can solve the problems of relying on single-layer corrugated paper or foam filling during use. The pressure resistance is limited to one direction, and the cushioning effect is insufficient for multi-angle impacts (such as drops and squeezing), which can easily lead to damage to fragile items inside. Ordinary adhesive seals can only be used once and cannot meet the needs of users to open and close them repeatedly (such as document bags that need to be repeatedly stored and retrieved), resulting in a significant decrease in sealing performance after secondary sealing. Existing RFID tags are usually attached to the surface of the bag body, which has the problem of easy wear and tear and detachment of the tags.

[0037] It should be noted that during the use of the bag body 10, the honeycomb paper 50 absorbs the impact force when the bag body 10 is impacted, protecting the documents and items inside the bag body 10. At the same time, when the RFID tag 70 is installed, the identification area 60 can be aligned or aligned with the detection equipment when the bag body 10 is identified and detected, so as to facilitate quick identification.

[0038] By using two sets of adhesive layers 30 and release paper 40, when the connecting area 20 is used for a single sealing purpose, one set of release paper 40 is torn off to bring the adhesive layer 30 into contact with the bag body 10 and seal the bag body 10. When the bag body 10 needs to be reused, the other set of release paper 40 is torn off along the outside of the adhesive layer 30, thereby ensuring that the connecting area 20 and the bag body 10 can be sealed again, thus completing the reuse of the bag body 10, avoiding disposal after a single use, and saving resources.

[0039] In this embodiment, in the practical application of the bag body 10, the honeycomb paper 50, as the core buffer layer, has the characteristic of being replaceable. Specifically:

[0040] First, alternative materials:

[0041] The honeycomb paper 50 can be replaced with any of the following fillers before assembly:

[0042] Environmentally friendly materials: compressed waste paper (such as recycled pulp blocks), biodegradable foam (such as PLA foam granules);

[0043] High-performance cushioning materials: corrugated cardboard (flute height 3-5mm), EVA foam (density 0.03-0.1g / cm³). 3 ), air column bag array;

[0044] Functional fillers: phase change material capsules (for constant temperature transport), activated carbon fiber layer (for moisture and mildew protection).

[0045] Second, the replacement technology logic: the filler must meet the following conditions to ensure compatibility:

[0046] Size compatibility: The thickness range is controlled within 5-15mm, with a tolerance of ±0.5mm, to ensure matching with the label slot (depth 2-8mm) and the bonding surface of the outer kraft paper (11 / 12);

[0047] Mechanical properties: Static compressive strength ≥50kPa, dynamic impact absorption rate >70% (according to ASTM D1596 standard);

[0048] Process feasibility: It can withstand the hot-press sealing process (temperature ≤180℃, pressure ≤1.5MPa) without structural collapse or performance degradation.

[0049] Operating steps:

[0050] Taking waste paper as an example:

[0051] First, waste paper is crushed and molded into a honeycomb substrate (unit pore size 8-12mm), and then surface adhesive is applied (coating amount 8-12g / ㎡) to enhance the adhesion to kraft paper.

[0052] Secondly, an RFID tag groove (3mm deep) is pre-embedded in the middle of the substrate, and the groove is sealed by high-frequency heat sealing (frequency 27.12MHz) after the tag is embedded.

[0053] Finally, the original honeycomb paper 50 was replaced for bag assembly. Its cushioning performance test showed that when dropped from a height of 1.5m, the peak acceleration of the internal items was ≤60G (ISO 2248 standard).

[0054] In one embodiment, a rectangular groove-type label slot is formed in the middle of the honeycomb paper 50, with a depth of 1 / 2 to 2 / 3 of the honeycomb paper thickness, and a 0.1-0.3mm buffer gap is reserved at the bottom of the slot. After the RFID tag 70 is embedded, the slot wall shrinks inward by 3%-5% through a hot-pressing process, forming a four-point snap-fit ​​wrapping (each side produces a 0.5mm raised indentation) to prevent the tag from shifting. During assembly, the RFID tag 70 is first pre-fixed in the slot of the honeycomb paper 50 using ultrasonic welding, and then the outer kraft paper 11 and the inner kraft paper 12 are covered in sequence. The edge of the bag is then sealed by hot-pressing at 160-180℃, with the pressure controlled at 0.8-1.2MPa, for 3-5 seconds.

[0055] In one embodiment, it further includes: an identification area 60 provided on the outside of the bag body 10 and corresponding to the RFID tag 70, wherein a rectangular identification area 60 is provided on the outer surface of the bag body 10, and the area is composed of the following structure:

[0056] Positioning marking layer: Dark cross positioning lines are printed on semi-transparent PET film with a line width of 0.5mm and an error of ≤1mm with the center point of the RFID tag 70;

[0057] Signal penetration layer: A circular wave-transmitting hole with a diameter of 10mm is opened on the inner kraft paper 12 at the corresponding position of the identification area 60. The hole is filled with a silicone layer (thickness of 0.2mm) with a dielectric constant ≤2.5 to ensure that the RFID read and write signal attenuation is <3dB.

[0058] In one embodiment, the RFID tag 70 is a flexible structure. The RFID tag 70 uses a polyimide substrate (0.05mm thick), and the antenna portion is a serpentine copper foil (0.1mm line width, 0.3mm spacing). The chip is encapsulated with epoxy resin (Shore A 40-50 hardness). When the bag's 10-fold bending radius is ≥30mm, the tag's maximum strain is ≤0.8%, making it suitable for cold chain transportation (-20℃ to 50℃) or extrusion stacking scenarios.

[0059] In one embodiment, 3-5 parallel hot melt adhesive strips (2mm wide, 8-10mm spaced) are applied to the sides of the outer layer 11 and inner layer 12 near the honeycomb paper 50. After curing, the height of the adhesive strips is 0.1-0.15mm. After plasma treatment, the surface energy of the honeycomb paper 50 and the adhesive strip contact surface is ≥50mN / m, and the adhesive peel strength is ≥2.5N / cm. During pre-bonding, the bonding pressure between the adhesive strip and the honeycomb paper 50 is 0.3-0.5MPa, and the temperature is 80℃ for 2 seconds. After positioning, the process proceeds to the main hot pressing process.

[0060] In one embodiment, the width of the release paper 40 is greater than the width of the adhesive layer 30, specifically, the width of the release paper 40 is 2-3 mm wider than the adhesive layer 30, and the edges are chamfered at 30°. The substrate of the release paper 40 is silicone paper (60-80 g / m²), with a silicone coating of 3-5 g / m², and the peel force is controlled at 0.05-0.1 N / 25 mm. When the release paper 40 covers the adhesive layer 30, a 0.5-1 mm unbonded allowance is formed on each side to prevent dust from seeping in along the edges.
