Description
Technical Field
[0001] The utility model relates to the technical field of coated paper, and more specifically to a coated paper with antibacterial effect. Background Art
[0002] Laminated paper is a composite material made by coating plastic particles on the surface of paper through a casting machine. The main features of this composite material are that it is oil-proof (relatively), waterproof (relatively), and heat-sealed. Different uses have different features: when used to package hamburgers, it is oil-proof. McDonald's uses edible vegetable oil at 80 degrees for ten minutes without oil leakage. When used for coated paper packaging, it is waterproof. When used for automatic packaging machines, it is heat-sealed.
[0003] However, the existing coated paper has the following problems when used:
[0004] (1) When using laminated paper, it is usually necessary to tear the laminated paper manually. When tearing the laminated paper, people usually pull the laminated paper roll by hand and tear it through the dotted lines set on the laminated paper. However, this will cause the torn laminated paper to be too uniform in size. For some large items, the paper roll needs to be rolled continuously to reach the required length. However, this length of laminated paper is composed of multiple tearable laminated papers, and there are still tearable dotted lines between them. When wrapping, the laminated papers are easily torn apart, which is not conducive to the wrapping and protection of large items;
[0005] (2) Secondly, when the existing laminated paper is in use, the internal structure is relatively simple, with only an inner laminated layer and a waterproof layer. When people's hands come into direct contact with the laminated paper, the bacteria on the hands are likely to remain on the laminated paper. In addition, the laminated paper is also exposed to the air for a long time, and the bacteria in the air will also remain on the laminated paper. The bacterial residue on the laminated paper can easily contaminate food, causing the food to spoil faster, which in turn affects health.
[0006] The utility model can freely adjust the length of the coated paper according to the demand when tearing it, can effectively inhibit the growth and reproduction of bacteria, prevent the food from being contaminated by microorganisms, and prolong the shelf life of the food.

[0012] A further preferred embodiment: the material of the antibacterial layer is any one of nanosilver particles, quaternary ammonium salt compounds, chitosan, natural plant extracts, organic metal complexes, and metal oxides.
[0013] A further preferred solution is that a foot is provided at one end of the chassis, a suction cup is fixedly installed at the end of the foot close to the wall, and a connecting strip is provided inside the chassis, and the connecting strip is fixedly connected to the rear end of the limiting strip.

When the laminated paper is torn, the laminated paper roll can be reversed by rotating the handle and rewound into the winding machine to be protected by the winding machine, so as to prevent the laminated paper roll from being exposed to the outside for a long time and being damaged by collision;

The rear end of the fixed plate 501 is fixedly connected to the connecting strip 402. When using coated paper, the winding shaft 2 inside the winding machine 1 is rotated by turning the winding handle 201, and the surface of the winding shaft 2 is rotated around the set coated paper roll. When the coated paper roll rotates outward, one end of the coated paper roll will extend outward from the paper outlet 101. At this time, the user can continue to output through the winding handle 201 to make the coated paper body 3 continue to extend outward. When the length is sufficient, the coated paper body 3 is pulled and moved upward to make the coated paper body 3 contact the cutting blade 102. The teeth at the bottom of the cutting blade 102 will pierce the coated paper body 3, making it easier to tear the coated paper body 3, and it can be cut according to the user's own needs. , comes from pulling the paper roll, and finally pierces and tears the coated paper body 3 through the teeth. After the coated paper body 3 is torn out, the coated paper body 3 is retracted into the inside of the winder 1 by reversing the winding handle 201, so that the coated paper body 3 is protected by the winder 1. When installing the winder 1, the suction cup 403 on the chassis 4 is adsorbed on the wall, which can make the winder 1 fixed on the wall more stably. At the same time, the limit strip 5 can clamp the surface of the winder 1 through the rotating shaft 502, so that the outer shell of the winder 1 and the chassis 4 are fixed more stably, and will not shake easily when the winding shaft 2 is rotated.

The upper end of the inner coating layer 301 is a reinforcement layer 302, the upper end of the reinforcement layer 302 is a waterproof layer 303, the upper end of the waterproof layer 303 and the bottom of the inner coating layer 301 are both antibacterial layers 304, the bottom of the antibacterial layer 304 at the bottom of the inner coating layer 301 is an aluminum foil layer 305, and the material of the antibacterial layer 304 is any one of nano silver particles, quaternary ammonium salt compounds, chitosan, natural plant extracts, organic metal complexes, and metal oxides. When the coated paper body 3 is used, The inner lining layer 301 is the innermost layer, which has the function of absorbing oil. It is generally made of polypropylene chemical fiber material, and its thickness is usually between 0.2-0.4mm. The reinforcement layer 302 is used to increase the strength and toughness of the lining paper to make it more durable. It is located on the upper end of the inner lining layer 301 and is usually made of glass fiber. On the upper end of the reinforcement layer 302 is the waterproof layer 303, which is usually made of pp synthetic paper and has the functions of waterproof and oil-proof. Its thickness is generally between 0.15-0.25mm. The antibacterial layer 304 is on the upper end of the waterproof layer 303 and the bottom of the inner lining layer 301. It has a good antibacterial effect and can inhibit the growth of bacteria and microorganisms to ensure The hygiene and safety of coated paper, the nano silver particles used have strong antibacterial properties; quaternary ammonium salt compounds can destroy the cell membrane of microorganisms; chitosan has natural antibacterial activity; natural plant extracts are environmentally friendly and have certain antibacterial effects; organic metal complexes and metal oxides can also play an antibacterial role. Different materials are selected according to the purpose to make the antibacterial layer 304, the bottom of the inner coating layer 301 and the bottom of the antibacterial layer 304 are aluminum foil layers 305, which have good barrier properties and can block the penetration of light, gas, etc. Secondly, the position of the antibacterial layer 304 is not fixed, and can be set at different positions according to different uses. When it is the outermost layer, it can directly contact the bacteria and microorganisms in the external environment and play an immediate antibacterial role. For example, in food packaging, the outside may be exposed to various pollution sources. Setting the antibacterial layer 304 in the outermost layer can effectively inhibit the growth and spread of bacteria on the packaging surface; when it is in the middle layer, the antibacterial components can be protected to a certain extent and the influence of external factors on the antibacterial effect can be reduced.

When the coated paper body 3 is extended to a sufficient length, the coated paper body 3 is pulled upward to make the coated paper body 3 contact the cutting blade 102. The teeth at the bottom of the cutting blade 102 will pierce the coated paper body 3, making it easier to tear the coated paper body 3. Then the coated paper body 3 is put into use, and the coated paper body 3 is The outermost layer is an antibacterial layer 304, which can effectively inhibit the growth and spread of bacteria on the packaging surface. At the same time, the inner side of the laminated paper body 3 that contacts the article is an aluminum foil layer 305, which has good barrier properties. When the article is wrapped, it can prevent the gas of the article from penetrating outward, and the oil on the surface of the article can be adsorbed through the inner laminated film layer 301. The waterproof layer 303 and the reinforcing layer 302 make the laminated paper body 3 have better strength and toughness, making it more durable. At the same time, it has waterproof and oil-proof functions, which can prevent external water and oil from entering the interior of the laminated paper body 3.
