Description

Portable easy-to-open adhesive tape

Technical Field

The utility model relates to a non-setting adhesive tape (adhesive tape) field, in particular to portable easy-open sticky tape.

Background

The self-adhesive paper (tape) is made up by using white paperboard (or PVC) with higher strength as base material and coating self-adhesive paper, and is mainly used for printing trademark and label or as packaging material. The structure of the device comprises from top to bottom: 1) coating: corona treatment or printing treatment (printing treatment); 2) the surface paper is divided into coated paper, PET/PVC and the like according to the material, and the back of the surface paper is coated with an adhesive; 3) gluing: the types are permanent sticking (strong sticking), removable (weak sticking) and re-sticking; 4) the base paper comprises common base paper and glassine base paper, and the surface of the base paper is coated with a silicon oil layer which has a barrier effect on the adhesive.

The prior adhesive tape has the problems that the tape head is difficult to identify and open in the using process, and the unsealing is difficult after the adhesive tape is packaged.

The utility model discloses a chinese utility model patent application number is 201721829253.5 discloses a non-setting adhesive tape convenient to tear off, including substrate layer and plastics rete, the middle part of the downside of plastics rete forms convex thickening portion, and the substrate layer sets up the both sides at the thickening portion of the downside of plastics rete, and the bottom surface of substrate layer flushes with the bottom surface of thickening portion, and the coating has the non-setting adhesive on the substrate layer, and the centre of thickening portion sets up one and peels off the groove, and the both sides of thickening portion form the recess of indent respectively. Is characterized by easy tearing off.

The utility model discloses a chinese utility model patent of application number 200520067530.4 is novel adhesive tape, including a basic unit, be provided with the fixed cover of a plurality of exclusive use adhesive on the basic unit in succession, this fixed cover of adhesive has half confined accommodation portion. During the use process, the adhesive fixing sleeve can be taken down by using the mode that the adhered object is inserted into the adhesive fixing sleeve, and the adhesive fixing sleeve cannot be contacted with the adhesive layer when being taken down.

Therefore, the adhesive sticker in the prior art is improved to improve the service performance, and the adhesive sticker has wide market demands.

Disclosure of Invention

The utility model aims at providing a portable easy-open sticky tape overcomes prior art's is not enough, adopts to set up on the face of gluing and does not have to glue or subtract the gluey strip to bright color mark, convenient discernment sticky tape head position, it is convenient to open during the use, and the unsealing discernment is obvious after the packing is used, thereby conveniently unseals.

In order to achieve the above object, the solution of the present invention is that:

the portable easy-to-open adhesive tape comprises a base material layer and an adhesive layer, wherein a strip is arranged in the length direction of the adhesive layer and is a non-adhesive area or a low-viscosity adhesive area, a color coating is sprayed or electroplated on the strip, and the width of the strip is 3-8 mm.

Preferably, the strip is located on the middle, one side or both sides of the tape.

Preferably, the substrate layer is any one of OPP, BOPP, PE, PET or PVC.

Preferably, the low-viscosity glue area is an area coated with a glue layer in a grid shape or a lattice shape.

Preferably, the adhesive layer is a natural rubber layer and a polymethyl methacrylate adhesive layer with the thickness of 20-100 micrometers.

Preferably, a corona treatment layer is arranged between the base material layer and the adhesive layer.

Compared with the prior art, the beneficial effects of the utility model are that: through adopting partly not having glue or subtracting gluey technology, can be in the same place with current sticky tape manufacturing process integration, furthest has promoted the practicality of this section product in the coiling process, and is simple high-efficient, does not increase manufacturing cost, and convenience of customers uses sticky tape in-process discernment sticky tape head position, opens easily, reachs through the practice, and the back head discernment of packing is obvious, and very convenient the unsealing, and the whole cohesive force of sticky tape also can satisfy the operation requirement.

Detailed Description

The structure of the present invention will be further described with reference to the following embodiments:

in the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

See fig. 1-fig. 3, is the utility model discloses portable sticky tape of easily opening embodiment structure schematic diagram, including substrate layer 1 and viscose layer 2, be equipped with strip 3 in low viscosity glue district along the length direction on viscose layer, the spraying or the electroplating have colored coating 4 on the strip 3, and the color is bright-colored, 3 width 3~8mm in strip, and the preferred value is 5 mm.

In the embodiment, the strip 3 is located in the central position of the tape. The substrate layer 1 is transparent PVC. The position of the adhesive layer 2 outside the strip is coated with a 60 micron polymethyl methacrylate adhesive layer. The colored coating 4 of the strip 3 is provided with an adhesive layer 2 which is coated with a polymethyl methacrylate adhesive layer with the thickness of 30 microns in a lattice shape. The lattice distribution is that the glue spreading area accounts for 25% -30% in each square centimeter, and the function of reducing the viscosity is achieved. The strip 3 areas may also be left without glue.

In order to obtain the matte effect, a corona treatment layer 5 can be arranged between the base material layer 1 and the adhesive layer 2, and the transparency of the base material layer subjected to corona treatment is reduced, so that the color coating at the end part of the adhesive tape is easier to identify, and the tape head is convenient to find or unseal.

In the embodiment, the substrate layer 1 may also be any one of OPP, BOPP, PE, and PET. The adhesive layer 2 can be a natural rubber layer. The strip 3 may also be provided on one or both sides of the tape as desired. The low-viscosity glue area on the strip 3 can also be a grid-shaped glue coating area coated with a 20-100 micron natural rubber layer and a polymethyl methacrylate glue layer.

The utility model discloses the sticky tape can be rolled up according to current technology and is made and use, satisfies the user demand of various packagings.

The above embodiments are merely specific examples selected for the purpose of illustrating the objects, technical solutions and advantages of the present invention in detail, and all modifications, equivalents and improvements made without departing from the spirit and principles of the present invention should fall within the protection scope of the present invention.
