Referring to fig. 1 in combination, an embodiment of the present invention provides an environmentally friendly packaging sheet 10, and the present application will be further described with reference to these drawings.
The environment-friendly packaging sheet 10 comprises a wiping layer 11 and a bottom layer 12 which are stacked.
The wiping layer 11 comprises a seaweed nonwoven fabric, and in a specific embodiment, the seaweed nonwoven fabric is a nonwoven fabric prepared from sodium alginate fibers, specifically, the seaweed nonwoven fabric is formed by using hot air, spunbond or melt blown technology to form the sodium alginate fibers, wherein the content of the sodium alginate fibers in the seaweed nonwoven fabric is greater than or equal to 65%.
In a preferred embodiment, the seaweed nonwoven fabric is prepared as follows:
s1: providing a mixed fiber of sodium alginate fibers and PP fibers, wherein the ratio of the sodium alginate fibers to the PP fibers is 2-4:1;
s2: carding the mixed fibers by using a carding machine;
s3: and (3) carrying out penetration bonding by adopting hot air at 160-200 ℃ to obtain the hot air seaweed non-woven fabric.
The bottom layer 12 is a water repellent film, which may be a PE film or the like, and is not limited thereto.
Further, the environment-friendly packaging sheet 10 is formed as follows:
s21: corona polarization treatment is adopted to the water repellent film, so that the surface of the water repellent film has charges opposite to those of the seaweed non-woven fabric.
In a specific embodiment, corona treatment can be performed on the surface of the water repellent film by using a corona machine, specifically, the output power range of the corona machine is 5-50kW, the frequency adjustment range is 10-25kHz, the treatment voltage range is 5-18KV, and the treatment time is 1-2min. The corona oxidizes and polarizes molecules on the surface of the water repellent film and activates the surface so as to increase the adhesion ability of the surface of the water repellent film, and it is understood that, generally, the seaweed nonwoven fabric has a positive polarity, and the surface of the water repellent film is negatively charged when the water repellent film is corona-treated.
S22: and paving seaweed non-woven fabrics on the surface of the water repellent film subjected to corona polarization treatment, wherein the seaweed non-woven fabrics are combined with the water repellent film through positive and negative ionic bonds.
Further, the seaweed nonwoven fabric may be electrostatically treated before being laid and the seaweed nonwoven fabric may be made to have a charge opposite to that of the water repellent film, it being understood that in this case the seaweed nonwoven fabric may be positively charged or negatively charged, but the water repellent film must be made to have a charge opposite to that of the seaweed nonwoven fabric.
It can be appreciated that in the present application, the seaweed nonwoven fabric and the water repellent film are combined by positive and negative ionic bonds, and the wiping layer 11 and the bottom layer 12 are not bonded by an adhesive, and meanwhile, the seaweed nonwoven fabric and the water repellent film are tightly attached, and can be easily separated from the water repellent film, that is, when in use, a user can use the seaweed nonwoven fabric and the water repellent film together, and can also peel the seaweed nonwoven fabric from the water repellent film for single use, so that the use flexibility is increased.
Meanwhile, the wiping layer 11 further comprises a microcapsule 13, the microcapsule 13 comprises a wall material and a core material, wherein the wall material is sodium alginate, the core material can be a cleaning agent, a bacteriostatic agent or a humectant, and specifically, the cleaning agent can be selected from alkylaryl sulfonate, secondary alkyl fatty hydrocarbon sulfonate, alkyl sulfate, sodium dodecyl polyoxyethylene ether sulfate, sodium dodecyl sulfate, aminopropionate, iminopropionate, polyoxyethylene ether, alkyl glycoside and derivatives thereof, fatty alcohol polyoxyethylene ethers, alcohol amides and the like.
The humectant mainly comprises polyhydric alcohols such as glycerol, diglycerol, polyethylene glycol, propylene glycol, hexylene glycol, polypropylene glycol and the like; sugars such as sorbitol, glucose, xylitol, maltitol, mannitol;

The microcapsules 13 may be formed by coagulation, complex coagulation, freeze-drying, freeze-spraying, or the like.
Further, the microcapsules 13 are disposed inside the wiping layer 11, more specifically, the microcapsules 13 are fixed on the fibers forming the seaweed nonwoven fabric, and in a specific embodiment, the microcapsules 13 may be added in the mixed fibers in the step S1, the microcapsules 13 are fixed on the fibers during carding and web forming, and the microcapsules 13 are formed inside the seaweed nonwoven fabric after drying.
Further, the microcapsule 13 has a particle size of 1 to 20 μm, and when the particle size is too large, it is easily broken during formation of the seaweed nonwoven fabric, and when the particle size is too small, it is difficult to break during use, releasing the core material.
It will be appreciated that the environment-friendly packaging sheet 10 of the present invention uses the seaweed nonwoven fabric as the wiping layer 11, and the seaweed nonwoven fabric itself has antibacterial property, and is a surfactant, which has self-cleaning property, and can easily clean the predetermined position, and the wiping layer 11 contains the microcapsules 13, so that the microcapsules 13 are broken to release the core material during the wiping process, or the microcapsules 13 are broken to release the core material by rubbing before use, so as to increase the cleaning and cleaning effects.

More preferably, the top sheet 31 is the same as the seaweed nonwoven fabric used for the wipe layer 11, and the same refers to the same material and basis weight.
The absorbent body 32 is disposed between the top sheet 31 and the bottom sheet 33, and specifically, the absorbent body 32 is suitably connected by entanglement of a plurality of fibers to form a three-dimensional network structure, a plurality of pores are distributed between the three-dimensional network structure, a polymer absorbent material (SAP) is contained between the three-dimensional network structure, and the pores can absorb and diffuse liquid, and the polymer absorbent material can absorb and retain liquid, and the fibers can be fluff pulp.
In some embodiments, the absorber 32 further includes a coating layer for coating the three-dimensional network structure, and the typical coating layer is disposed on the upper side and the lower side of the three-dimensional network structure, for preventing the polymer absorbent material between the three-dimensional network structure from precipitating to the surface of the absorber 32 through the pores and preventing the polymer absorbent material from decreasing the absorption effect of the absorber 32 due to the dissipation of the air flow under the negative pressure during the manufacturing process of the absorber 32.
The backsheet 33 is disposed on a side away from the skin of the user, and in order to prevent the liquid from soiling the clothing of the user through the wipe layer 1111, the backsheet 33 is typically a water-repellent material, specifically, a PE film, SMS nonwoven fabric, or the like, and preferably the backsheet 33 is capable of passing a gas such as water vapor while the liquid is not passed, so that it is not smoky during use.
It will be appreciated that for the self-cleaning pad of the present application, the core material of the first microcapsule 13 may be released by squeezing the first microcapsule 13 of the packaging sheet material before use, so that the wiping layer 11 is provided with a bactericide or a cleaning agent to clean and clean a predetermined skin area, thereby avoiding embarrassment of not having cleaning articles on the one hand, and achieving comprehensive utilization of the pad packaging and the pad body 30 on the other hand.
The foregoing description is only of embodiments of the present invention, and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
