Abstract
The utility model provides a sealing adhesive tape with a hierarchical structure. The sealing adhesive tape comprises a base body, wherein an adhesive area and a non-adhesive area are arranged on the upper surface of the base body; the adhesive area comprises an upper part and a lower part, which are in a stepped shape; and the non-adhesive area is arranged adjacent to the lower part of the adhesive area. Adhesive with unequal gram weights (thicknesses) is arranged on the sealing adhesive tape, so that the sealing adhesive tape is easy to be torn off from a packing bag body and is firmly adhered to a sealing tongue all the while.
Description
Technical field
The utility model relates to a kind of sealing tape, is meant a kind of sealing tape with hierarchical structure especially.
Background technology
Use for convenient, existing small package bag (as Packing bag for facial tissue or sanitary towel package etc.) mostly is provided with one in order to the easily openable mouth with content taking-up use, and at easily openable mouth place one sealing tape is set.For instance, commercially available Packing bag for facial tissue is generally the packaging bag of nonrigid plastic cuboid, one side of cuboid packaging bag is provided with one and comprises easily broken tooth trace and the easily openable mouth that seals tongue, owing to often be placed with plurality of sheets of paper towel in the existing Packing bag for facial tissue, therefore, when in packaging bag, also having the paper handkerchief residue, also need to use a sealing tape so that the easily openable mouth is sealed once more, existing sealing tape is mostly by a matrix, and be arranged at the hot melt adhesive layer of this matrix one side surface and do not glue district's composition, during use, the hot melt adhesive layer of sealing tape bond simultaneously the packaging bag body and the envelope tongue, and the adhesive surface of hot melt adhesive layer and envelope tongue is greater than the adhesive surface of hot melt adhesive layer and packaging bag body, make the cohesive force of hot melt adhesive layer and envelope tongue greater than the cohesive force of itself and packaging bag body, by above-mentioned structure, make that sealing tape both had been easy to tear off from the packaging bag body, and secure bond is being sealed on the tongue all the time.
Yet, in above-mentioned mode, what adopt with the bonded assembly hot melt adhesive layer of packaging bag with the bonded assembly hot melt adhesive layer of envelope tongue is same kind, the hot melt adhesive of same grammes per square metre, therefore, it is identical with packaging bag body or the bonded assembly unit of envelope tongue bond strength, like this, when glue viscosity is too big, sealing tape will be difficult to tear off from the packaging bag body, in case and the user is firmly excessive, then can cause packaging bag body or envelope tongue breakage, otherwise, when glue viscosity was not enough, the user one firmly will make sealing tape break away from packaging bag body and envelope tongue simultaneously slightly, is difficult to play the leak free effect.
The utility model content
The utility model provides a kind of sealing tape with hierarchical structure, in order to solve the above-mentioned problems in the prior art.This sealing tape is provided with the viscose glue that grammes per square metre (thickness) does not wait, thereby makes that sealing tape both had been easy to tear off from the packaging bag body, and secure bond is being sealed on the tongue all the time.
The technical solution of the utility model is as follows:
Sealing tape with hierarchical structure comprises a matrix, it is characterized in that: the upper surface of this matrix is provided with the not sticking district of an adhesive area and, and this adhesive area comprises the upper and lower that is stairstepping, and described not sticking district is provided with in abutting connection with the bottom.
As further improvement of the utility model, the lower surface silicon-coating oil reservoir of this matrix, like this, in process of production, a large amount of sealing tapes of producing directly can be curled stores, and need not to worry that viscose glue can be transferred on the lower surface of matrix.
As further improvement of the utility model, the grammes per square metre on this adhesive area top is than the many 1～15g/m of grammes per square metre of adhesive area
2
As further improvement of the utility model, the grammes per square metre on this adhesive area top is 15～25g/m
2, the grammes per square metre of this adhesive area bottom is 10～22g/m
2
As further improvement of the utility model, described adhesive area top and adhesive area bottom are provided with continuously.
As further improvement of the utility model, between described adhesive area top and the adhesive area bottom spacer region is set.
As further improvement of the utility model, described matrix is made up of a nonwoven layer and a plastics leaching membrane layer, this nonwoven layer is captiveed joint with this plastics leaching membrane layer, the lower surface of this nonwoven layer applies described silicon layer, and the upper surface of this plastics leaching membrane layer then is disposed with described adhesive area top, adhesive area bottom and not sticking district.In above-mentioned structure, nonwoven layer provides the soft-surface of sealing tape, promote whole feel and class, the plastics leaching membrane layer then plays the effect that connects nonwoven layer and adhesive area, and can prevent that viscose glue from infiltrating into nonwoven layer, be arranged within the nonwoven layer because plastics drench film, do not influence the feel and the outward appearance of matrix.
As further improvement of the utility model, described matrix is a plastic sheeting, and described plastic sheeting can be PP film or PE film or PVC film etc.
As further improvement of the utility model, described matrix, adhesive area and the not sticking shape of distinguishing are not limit, and can adjust voluntarily according to the shape of packaging bag, easily openable mouth.
Compare with prior art to description of the present utility model as can be known by above-mentioned, the utlity model has following characteristics:
1) by adhesive area top and the adhesive area bottom that grammes per square metre does not wait is set, make the viscosity on adhesive area top greater than the viscosity of adhesive area bottom, thereby make that sealing tape both had been easy to tear off from packaging bag body (with adhesive area bottom bonding), and secure bond is being sealed on the tongue (with adhesive area top bonding) all the time;
2) the utility model adopts a nonwoven layer and a plastics leaching membrane layer to form matrix jointly, and it provides soft-surface by nonwoven layer, promotes whole feel and class.
