Abstract
The utility model discloses double-sided hot sealing filter paper, comprising a wood pulp base layer, wherein the upper surface of the wood pulp base layer is covered with an upper tomato fiber layer with hot-pressing viscidity; a lower tomato fiber layer which is formed by the upper tomato fiber layer infiltrating to the lower surface of the wood pulp base layer from the wood pulp base layer is arranged on the lower surface of the wood pulp base layer. The double-sided hot sealing filter paper is reasonable and simple in structure, doubled-sided hot sealing bag making can be achieved in the packing process, and hot-pressing setting can be implemented regardless of the orientation of the filter paper in the machining process, so that the bag making efficiency is improved, the rework cost of an enterprise is saved, and the returned and repackaged tea is not polluted for the second time. In addition, the wet strength and the filtering speed of the filter paper are improved by the upper and lower tomato fiber layers and the tomato fibers infiltrating into the wood pulp base layer, and the tomato fibers are safe, healthy and non-toxic, and resistant to soaking in boiling water. Thus, the double-sided hot sealing filter paper is applicable to packaging and using of various tea, and easy to popularize and utilize.
Description
Technical field
The utility model relates to a kind of filter paper, especially a kind of for sealing the two-sided heat-sealing filter paper of tealeaves.
Background technology
Along with the quickening day by day of the modern life, the product of simple and fast is more and more subject to liking of people, a small amount of tealeaves is put into filter paper bag and seal into tea bag, filter for tealeaves, can solve people in the time of daily having tea, be tired of in tealeaves floating and the slag of serving the tea, owing to there being above-mentioned advantage, the first-selection that increasing people selects tea bag to have tea as oneself; In tea bag manufacturing company, what use is that one side heat-sealing filter paper is used for filtering envelope tealeaves, because only having one side, filter paper has heat-sealable fiber material, so in the time sending into machine heat-sealing, often do anti-heat cover towards, the phenomenon that causes tea bag not seal, causes and does over again, thereby affect production efficiency, also can cause the tealeaves of being refunded again packaging to be subject to the risk of secondary pollution.In addition, the tea filter paper overwhelming majority is on the market manufactured paper with pulp and is formed by multiple industrial chemicals mixing, has the risk of composite pollution and increase poisonous and harmful substance.
Utility model content
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of filter paper healthy and safe, can two-sided heat-sealing is provided, and system bag adds man-hour, no matter filter paper is towards which face, can heat-sealing filter paper, and effectively reduce system bag processing cost, enhance productivity.
The utility model solves the technical scheme that its technical problem adopts: this two-sided heat-sealing filter paper, comprise wood pulp basic unit, wood pulp basic unit upper surface is coated with the upper tomato fibre layer with hot pressing viscosity, and wood pulp basic unit lower surface is provided with by upper tomato fibre layer and is penetrated into from wood pulp based layer main body the lower tomato fibre layer forming wood pulp basic unit lower surface.Like this, in the time that filter paper is hot-forming, when upper tomato fibre layer is through heating, pressurization, tomato fibre layer segment is melted, under the effect of pressure, upper tomato fibre layer is penetrated on the lower surface of wood pulp basic unit, overstocks and forms lower tomato fibre layer, thereby make the upper and lower surface of wood pulp basic unit all form tomato fibre layer; Upper and lower tomato fibre layer all has hot pressing viscosity, and be applied to the heat-sealing of tealeaves bag processed and add man-hour, no matter filter paper is towards which face, can heat-sealing filter paper, can greatly reduce production costs, save the resources of production; And tomato fibre safety and Health is nontoxic, resistance to boiling water bubble, uses safe, healthy.
Further, the thickness of upper tomato fibre layer is greater than the thickness of lower tomato fibre layer.Arrange like this, can promote the speed of filter paper hot pressing processing, and, filter paper heat-sealing effect and wet strength can be ensured.
Further, wood pulp basic unit is the whole wood pulp basic unit that manufactures paper with pulp.The existing filter paper overwhelming majority adopts plurality of raw materials to mix and manufactures paper with pulp and form, and have the hidden danger of composite pollution and increase the risk of poisonous and harmful substance, and whole wood pulp is manufactured paper with pulp and can be guaranteed that filter paper is not contaminated, and safety non-toxic, promotes the quality of filter paper.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, simple, in package processing process, can realize two-sided heat-sealing bag, add man-hour no matter filter paper towards any face, can seal moulding, improve the efficiency of system bag production and processing, save enterprise's cost of doing over again, also can not cause and be refunded the tealeaves of packaging again and be subject to secondary pollution; In addition, the setting of upper and lower tomato fibre layer and the tomato fibre of infiltration in wood pulp basic unit, all gets a promotion the wet strength of filter paper, the rate of filtration, and tomato fibre safety and Health is nontoxic, resistance to boiling water bubble, be suitable for all kinds of tea packagings and use, be easy to utilization and extention.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: wood pulp basic unit 1, upper tomato fibre layer 2, lower tomato fibre layer 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing: this two-sided heat-sealing filter paper, comprise wood pulp basic unit 1, wood pulp basic unit 1 upper surface is coated with the upper tomato fibre layer 2 with hot pressing viscosity, wood pulp basic unit 1 lower surface be provided be penetrated into from wood pulp basic unit 1 main body that wood pulp basic unit 1 lower surface forms by upper tomato fibre layer 2 tomato fibre layer 3.
The thickness of upper tomato fibre layer 2 is greater than the thickness of lower tomato fibre layer 3.
Wood pulp basic unit 1 is the whole wood pulp basic unit that manufactures paper with pulp.
In the time that filter paper is hot-forming, when upper tomato fibre layer 2 is through heating, pressurization, make tomato fibre layer 2 partial melting, under the effect of pressure, upper tomato fibre layer 2 is penetrated on the lower surface of wood pulp basic unit 1, overstock and form lower tomato fibre layer 3, thereby make the upper and lower surface of wood pulp basic unit 1 all form tomato fibre layer.In the time that tealeaves is packaged into tea bag, first a little tealeaves is placed on two-sided heat-sealing filter paper, now without consider filter paper towards, again that two-sided heat-sealing filter paper is folding, put into heat sealing machine, heating sealing part material, make it reach viscosity flow state after pressurization make it seal, tealeaves is just encapsulated in filter paper and has suffered like this.
Although the utility model illustrates and describes by reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation in form and details.
