Description

Technical Field

[0001] This utility model relates to a multifunctional oil-absorbing paper for snacks. Background Technology

[0002] With the popularization of casual snack culture, high-fat snacks such as potato chips, fried chicken, and hand-pulled pancakes are very popular among consumers. However, excessive oil intake is detrimental to health, and consumers often need to absorb surface oil when eating them. Currently, the common practice is to use ordinary napkins or kitchen paper for absorption, but these papers have obvious drawbacks: First, their wet strength is low, and they are easily damaged after absorbing oil, producing paper scraps that contaminate food; second, the paper fibers are not tightly bonded, easily sticking to the food surface, affecting the eating experience; third, their function is limited, only absorbing oil, and they cannot insulate against heat when handling freshly cooked hot food, and there is a lack of guidance on how to use them. Although there are products with good oil absorption performance, such as coffee filters, their shape, appearance, and functional design are not optimized for the immediate, small-portion, and portable consumption scenarios of snacks. Therefore, there is an urgent need for a special oil-absorbing paper designed specifically for snack scenarios, integrating efficient oil absorption, non-stick properties, and heat insulation to improve the user's health experience and eating pleasure. Summary of the Invention

[0003] This invention provides a multifunctional oil-absorbing paper for snacks to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are as follows: A multifunctional oil-absorbing paper for snacks includes an oil-absorbing paper body, which is a multi-layer composite structure, stacked and fixedly bonded together from top to bottom along the thickness direction: The soft-light matte surface layer is a micro-matte structure formed by calendering food-grade wood pulp. Additive geometry layers; The core oil-absorbing layer is a pulp layer made by uniformly mixing and forming food-grade wood pulp and food-grade porous adsorbent material. Micro-trapezoidal deepened heat-insulating and oil-absorbing core layer; the micro-trapezoidal deepened heat-insulating and oil-absorbing core layer is a biodegradable polylactic acid foam material layer with a honeycomb porous structure.

[0005] Furthermore, the augmented geometric layer is a food-grade wood pulp layer and has radial grooves with three-dimensional embossing.

[0006] Furthermore, the oil-absorbing paper body is divided in the plane into a central high-oil-absorbing area and a heat-insulating hand-held area surrounding the high-oil-absorbing area. The high-oil-absorbing area and the heat-insulating hand-held area are visually separated by color or texture differences.

[0007] Furthermore, the outer surface of the powerful oil-absorbing zone is provided with a wave-shaped, gear-shaped, or dot-matrix anti-stick pattern.

[0008] Furthermore, the food-grade porous adsorbent material in the core oil-absorbing layer is porous starch or diatomaceous earth, and the amount added is 5% to 10% of the dry weight of the pulp.

[0009] Furthermore, the average pore size of the honeycomb porous structure of the microtrapezoidal deepened heat insulation and oil absorption core layer is 50 μm to 200 μm.

[0010] This utility model has the following beneficial effects: (1) One sheet of oil-absorbing paper achieves three core functions: efficient oil absorption, non-sticking, and heat insulation, meeting the complex needs of snack scenarios.

[0011] (2) Through functional partitioning and visual guidance, it intuitively tells users how to hold the food and where to touch it, thus lowering the barrier to entry. The unique surface treatment and edge design ensure a smooth and unembarrassing user experience.

[0012] (3) It adopts a multi-layer composite structure, with each layer performing its own function. Through the synergistic effect of materials and structure, it achieves the effect of "1+1>2", with high oil absorption efficiency and strong physical properties.

[0013] (4) Not only is it suitable for various bagged and takeaway snacks, its exquisite appearance and independent packaging also make it a fashionable consumer product with social sharing attributes. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the exploded structure of the oil-absorbing paper in this embodiment.

[0015] Figure 2 This is a schematic diagram of the planar structure of this embodiment. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] The following is in conjunction with the appendix Figure 1 and Figure 2 This invention provides a detailed description of a multifunctional oil-absorbing paper for absorbing grease from the surface of snacks.

[0018] The multifunctional oil-absorbing paper for snacks provided in this embodiment is round in shape (it can also be designed as square, fan-shaped, etc. according to actual needs). It is suitable for flip-top use scenarios and can be used to absorb oil from the surface of high-oil snacks such as potato chips, fried chicken, and hand-pulled pancakes. At the same time, it solves the problems of traditional oil-absorbing paper being easily damaged, sticky, and lacking heat insulation.

[0019] The oil-absorbing paper body in this embodiment has a four-layer composite structure. Each layer is stacked sequentially from top to bottom along the thickness direction and fixed together with a food-grade adhesive. The materials, processes, and functions of each layer are as follows: Soft-light velvet matte surface 1.

[0020] Material selection: Food-grade high-strength wood pulp is used as the base material, and the wood pulp fiber length is controlled at 1.5-2mm (to ensure wet strength and avoid damage after oil absorption).

[0021] Processing technology: The surface is finely calendered using a three-roll calender at a temperature of 60-70℃ and a pressure of 0.3-0.5MPa, resulting in a uniform micro-textured structure (the height of the raised surface is about 5-10μm), giving it an overall matte texture.

[0022] Functionality: The micro-fine velvet structure reduces the contact area with the snack surface, preventing it from sticking to potato chips, fried chicken skin, etc. after absorbing oil. At the same time, the matte surface is not reflective, enhancing the appearance and texture. This layer can also be completely peeled off from the snack surface without any fiber residue.

[0023] Additive geometry layer 2.

[0024] Material selection: Food-grade wood pulp layer consistent with the soft velvet matte surface layer 1 to ensure interlayer bonding; Processing technology: The process involves pressing invisible radial grooves into a three-dimensional embossing pattern using a three-dimensional embossing machine. The groove width is 1-2mm, the depth is 0.5-1mm, and the included angle between adjacent grooves is 30° (forming a uniform radial distribution). No additional additives are used in the embossing process; the embossing is achieved solely through mechanical pressure shaping.

[0025] Functionality: On the one hand, the three-dimensional embossing can increase the fluffiness of the paper (increasing fluffiness by 20%-30%), enhance the overall toughness, and prevent damage after folding after absorbing oil; on the other hand, the radial grooves can guide the oil on the surface of the snack to spread from the center to the surrounding area, preventing the oil from accumulating in the central area and improving the uniformity of oil absorption.

[0026] Core oil-absorbing layer 3.

[0027] Material formulation: Food-grade wood pulp is used as the base material, and food-grade porous adsorbent material is uniformly mixed (porous starch is used in this embodiment, but diatomaceous earth can also be used instead), wherein the amount of porous adsorbent material added is 8% of the dry weight of the pulp.

[0028] Processing technology: The paper is mixed and formed using a paper machine at a speed of 80-100 m / min and a paper basis weight of 30-40 g / m², to ensure that the porous adsorbent material is evenly distributed in the pulp without agglomeration. Functionality: Porous starch has a specific surface area of ​​50-100㎡ / g, which can quickly absorb oil (2-3 times faster than ordinary napkins) and lock the oil firmly to prevent it from seeping back onto the surface of the snack. A single sheet of oil-absorbing paper can absorb 1.2-1.5g of oil (3 times that of ordinary napkins).

[0029] Micro-trapezoidal deepened heat insulation and oil absorption core layer 4.

[0030] Material selection: Biodegradable polylactic acid (PLA) foam material is used, with PLA resin purity ≥99%, which meets the safety standards for food contact materials.

[0031] Processing technology: It is prepared by micro-foaming molding process, with foaming temperature of 160-170℃ and foaming pressure of 0.8-1.0MPa, forming a honeycomb microcapsule structure (microcapsule diameter of 0.1-0.3mm), and the edge of this layer is slightly raised to the outside to form a "micro-trapezoidal" structure (trapezoidal height difference of 0.5-1mm).

[0032] Functionality: Internal honeycomb porous structure with an average pore size of 50 μm to 200 μm.

[0033] This embodiment achieves planar functional zoning through "visual identification + structural adaptation," and the specific design is as follows: Functional partitioning, Strong oil-absorbing zone 8: Located in the center of the oil-absorbing paper, it is circular (6-8cm in diameter). Its planar position corresponds exactly to the central area of ​​the core oil-absorbing layer 3 and the micro-trapezoidal deepened heat-insulating oil-absorbing core layer 4, ensuring concentrated oil absorption function. The outer surface of this area (i.e. the corresponding area of ​​the soft velvet matte surface layer 1) is provided with a wavy anti-stick pattern 9, with a pattern height of 0.3-0.5mm and a wavelength of 2-3mm, further reducing the contact area with snacks and enhancing the anti-stick effect.

[0034] Heat-insulated handheld area 12: It is arranged in a ring shape (2-3cm wide) around the strong oil-absorbing area 8. Its planar position corresponds to the outer area of ​​the micro-trapezoidal deepened heat-insulating and oil-absorbing core layer (4), and it mainly undertakes the functions of heat insulation and handheld use. Visual demarcation 10: A clear demarcation is formed between the powerful oil-absorbing area 8 and the heat-insulating handheld area 12 through color difference - the powerful oil-absorbing area 8 is light yellow (food-grade yellow pigment, added amount ≤0.1%), and the heat-insulating handheld area 12 is dark gray (food-grade gray pigment, added amount ≤0.1%). No additional markings are needed to intuitively guide users to hold the dark gray area, reducing the usage threshold.

[0035] Edge design: The edge of the blotting paper body adopts a gear edge design with a gear pitch of 1-1.5mm and a gear height of 0.5mm, which not only enhances the aesthetics and fun, but also makes it easier for users to peel the blotting paper off the surface of the snack (avoiding edge jamming). LOGO icon area 5: The brand logo is printed at any gear tooth position in the heat-insulated handheld area 12 using flexographic printing technology (the printing ink is food-grade water-based ink with no odor), which does not affect the use function and can also achieve brand communication.

[0036] To meet the needs of portability and hygiene, the oil-absorbing paper in this embodiment is individually packaged: The packaging carrier is a playing card-style portable box (the box body is made of food-grade cardboard with a thickness of 0.3-0.5mm). Each portable box can hold 10-15 sheets of oil-absorbing paper. The box body has a flip-top opening (with a buckle structure at the opening to prevent the oil-absorbing paper from falling out). Each blotting paper is individually wrapped in food-grade polyethylene film (0.02-0.03mm thick) before being placed into the portable box to ensure that there is no dust or moisture contamination during storage, and that taking out a single sheet does not affect the hygiene of the other blotting papers.

[0037] The usage process of this utility model is as follows: Open the flip-top of the playing card-shaped portable case, take out an individually wrapped oil-absorbing sheet, and tear off the polyethylene film; Based on the color division 10, hold the dark gray heat-insulating hand area 12, and avoid finger contact with the light yellow strong oil-absorbing area 8. Place the snacks that need oil absorption (such as potato chips and fried chicken nuggets) on the surface of the strong oil absorption zone 8 and press lightly for 3-5 seconds (to ensure that the oil is fully absorbed). Snacks can be eaten immediately after removing them, and oil-absorbing paper can be discarded directly (because the micro-trapezoidal deep heat-insulating and oil-absorbing core layer 4 is made of biodegradable PLA material, the whole can be naturally degraded and there is no pollution).

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
