Description

Adhesive tape capable of being marked during writing

The technical field is as follows:

the invention relates to the technical field of adhesive tapes, in particular to a composite adhesive tape capable of being used as a mark for writing.

Background art:

as a common product, an adhesive tape has been used in various fields of national economy, and among them, a transparent adhesive tape using BOPP (biaxially oriented polypropylene) as a raw film is most commonly used. The adhesive tape is economical and practical, easily available in materials and very wide in use and application.

People often encounter the use of tape for labeling articles, such as the use of tape for packing certain articles, the use of marks on the packages of cosmetics and the like, and the like. But it is very inconvenient because writing cannot be directly performed on most tapes. Sometimes, a sticker of self-adhesive paper is used instead, but the written logo is easily worn and discolored.

The invention content is as follows:

technical problem to be solved

Aiming at the defects of the prior art, the invention provides the composite adhesive tape which can be used as a mark in a writing process, and the mark is not easy to wear.

(II) technical scheme

In order to achieve the technical effects, the invention adopts the following technical scheme:

the adhesive tape is a composite adhesive tape and is divided into two layers, namely an outer layer and an inner layer. The lining substrate is made of textured paper or similar materials, one surface of the lining coated with the viscose faces inwards, one surface of the lining coated with the anti-sticking materials faces outwards, and the width of the lining is narrow. The outer layer is transparent, typically a transparent substrate with a biaxially oriented polypropylene film as the original film, and the inward side is coated with a pressure sensitive adhesive layer and has a width wider than that of the inner layer.

The adhesive force of the outer layer of the pressure-sensitive adhesive layer is stronger than that of the inner layer of the pressure-sensitive adhesive layer, the outer layer of the pressure-sensitive adhesive layer is typically made of acrylate pressure-sensitive adhesive, the inner layer of the pressure-sensitive adhesive layer is made of masking tape with an adhesive layer, and therefore when the composite adhesive tape is directly torn off from the adhesive tape roll, the composite adhesive tape can keep the whole adhesion state.

When the mark is needed to be used, the transparent part of the outer layer is uncovered, the transparent part and the inner layer are in a partially separated state, then the outer side of the inner layer is written and marked, and the like, and finally the outer layer is recovered to be covered and stuck on the inner layer. If the label is not needed, the composite adhesive tape can be used as a common adhesive tape.

(III) the beneficial effects are as follows:

compared with the prior art, the composite adhesive tape has the following beneficial effects:

a, because the lining substrate uses the beautiful line paper or similar materials, and the antisticking surface is suitable for most writing tools such as ball pens, water pens and the like to write, and then the transparent material of the outer layer is used for covering, the protective action is achieved, and the mark can not fade and wear for a long time.

And B, because the anti-sticking surface of the beautiful line paper of the inner layer substrate is contacted with the outer layer transparent adhesive tape, the composite adhesive tape can be torn and pasted for many times, and the outer layer transparent adhesive tape is wider than the beautiful line paper of the inner layer substrate, so that the whole adhesive function of the composite adhesive tape cannot be influenced.

And C, because the two layers of composite materials are adopted, the width of the inner layer is narrow, so that the end opening of the adhesive tape can be easily found no matter the adhesive tape roll is taken off for use or needs to be taken off again after use.

The adhesive tape capable of being written on the upper surface of the label solves the problem that the adhesive tape is difficult to be marked.

In order to solve the technical problems, the embodiment of the application has the following general structure:

the invention adopts composite materials which are divided into an inner layer and an outer layer, wherein the base material of the inner layer is made of textured paper or similar materials, the outer layer is made of a common BOPP (biaxially oriented polypropylene) original film, the inner side of the outer layer is coated with a pressure-sensitive adhesive layer, and the width of the outer layer is wider than that of the inner layer.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

A tape capable of being used as a mark in upper writing is shown in figure 1, and figure 1 is a cross-sectional view, and the tape comprises an inner layer adhesive layer 1, an inner layer substrate 2, an outer layer pressure sensitive adhesive layer 3 and an outer layer substrate 4, wherein the outer layer is wider than the inner layer in width. When the adhesive tape is used, the inner layer adhesive layer 1 is adhered to the surface of an object to be adhered, then the outer layer of the adhesive tape is uncovered, a pen is used for writing or marking on the outer side surface of the inner layer of the adhesive tape, and then the outer layer is covered.

In one embodiment, the lining glue layer 1 and the lining base material 2 are made of masking tape.

In one embodiment, the outer pressure-sensitive adhesive layer 3 is made of rubber-type solvent-free pressure-sensitive adhesive or modified acrylic resin. Specifically, the rubber type solvent-free pressure-sensitive adhesive layer comprises the following raw materials in parts by weight: 85-100 parts of butyl rubber, 60-95 parts of terpene resin, 35-60 parts of PIB, 0.3-0.5 part of stabilizer and 0.3-0.6 part of antioxidant. The modified acrylic resin pressure-sensitive adhesive layer comprises the following raw materials in parts by weight: 65-80 parts of isooctyl acrylate, 5-25 parts of methyl acrylate, 10-25 parts of methacrylic acid, 0.1-1.2 parts of GMA, 0.1-1 part of TAIC, 0.1-2 parts of polyvinyl alcohol, 0.1-0.55 part of BPO and 0.1-2 parts of ammonia water.
