With the development of science and technology, various wallpaper is proposed in the market, such as: glass fiber printed wallpaper, cotton wallpaper, plastic wallpaper, fabric wallpaper, etc. Among them, plastic wallpaper is one of the plastic wallpaper that is developed rapidly and widely used at present, and PET-based wallpaper is one of the plastic wallpaper. The PET-based wallpaper generally comprises a release paper layer, a glue layer, a PET substrate layer, a pattern printing layer and the like; during production, the PET paster consisting of the release paper layer, the glue layer and the PET substrate layer is prepared, and then the pattern is printed on the PET paster to form the wallpaper. However, the existing PET sticker can have a serious glue overflow phenomenon during slitting and printing, so that a plurality of PET stickers are adhered together, and finally, the PET sticker cannot smoothly enter a printing process, so that the rejection rate is high. For this reason, the conventional solutions are: and talcum powder is coated on the edge of the sticker to seal the glue and prevent the glue from overflowing. However, although the method can effectively prevent the glue of the sticker from overflowing, the production cost of the wallpaper is increased, the production process of the wallpaper becomes more complicated, and the talcum powder can cause abrasion to equipment such as printing machines and the like.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the shortcoming and not enough that exist among the above-mentioned prior art, provide a PET sticker is glued to anti-overflow. The glue layer of the PET sticker is provided with an anti-overflow glue layer for prolonging the overflow distance of glue, so that the glue can be effectively prevented from overflowing, the PET sticker is prevented from being adhered in the printing process, and the edge of the sticker made into a finished product can not overflow the glue.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the utility model provides a PET sticker is glued to anti-overflow, its includes PET substrate layer, glue layer and the release paper layer that stacks gradually the setting, the glue layer comprises main glue film and anti-overflow glue film, the anti-overflow glue film is located main glue film's periphery, main glue film's thickness is 30 ~ 45 mu m, the thickness of anti-overflow glue film is 5 ~ 8 mu m, the horizontal width on anti-overflow glue film is 3 ~ 5 mm.

When the thickness of the main adhesive layer reaches 30-45 mu m, a good adhesion effect can be achieved, so that the sticker has good viscosity after being made into a finished product (namely wallpaper), and is not easy to fall off in use. Based on the main glue layer with the thickness, the thickness of the anti-overflow glue layer is designed to be 5-8 microns, the horizontal width is designed to be 3-5 mm, glue of the main glue layer can be effectively prevented from overflowing, the overflowing distance of the glue is prolonged, the sticker is guaranteed not to be adhered in the printing process, and glue cannot overflow at the edge of the wallpaper after being made into a finished product.

Because the thickness of the anti-overflow glue layer is smaller, the glue overflow phenomenon can not occur. If the thickness and the horizontal width of anti-overflow glue film surpass the scope of this application injectd, can lead to the rubber roll of printing machine to glue and lead to the sticker to scrap, perhaps can lead to the bite position inaccurate and lead to the fact the needle position to differ.

In the wallpaper production process, a plurality of stickers are generally produced at one time by using materials with large areas, and then are cut according to the designed specification (namely, the stickers are cut according to units) to form an independent sticker, and then the sticker is printed. The utility model discloses a sticker is the sticker of 1 unit, because the existence on anti-overflow glue layer, consequently, when cutting the sticker according to the unit, the excessive phenomenon of gluing can not appear, and the sticker after cutting can not take place gluing even yet, can the feeding smoothly to get into the printing process.

Preferably, the main glue layer and the anti-overflow glue layer are in seamless connection. At this time, the main glue layer and the anti-overflow glue layer can be connected integrally. When the glue layer is prepared, the thickness of the main glue layer and the thickness and the width of the anti-overflow glue layer can be preset through the existing gluing equipment, and then the main glue layer and the anti-overflow glue layer are formed through one-time gluing.

Preferably, the thickness of the main glue layer is 30 μm, the thickness of the anti-overflow glue layer is 5 μm, and the horizontal width of the anti-overflow glue layer is 3 mm. The thickness of the main glue layer is 30 mu m, so that the sticker has good viscosity, and the thickness of the anti-overflow glue layer is 5 mu m, the horizontal width is 3mm, so that the anti-overflow requirement of the main glue layer with the thickness can be met.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses the structure to the PET sticker is improved, ensure that the sticker has under better viscous prerequisite, the thickness to its main glue film has been injectd, and set up the excessive anti-overflow glue film of glue that can effectively prevent main glue film on the glue layer, avoid the PET sticker to take place to glue at the printing with the in-process of cutting even, make the PET sticker can cut smoothly and print, the production efficiency of wall paper has been improved, and the rejection rate has been reduced, also make the sticker not have glue to spill over at the back edge of finished wall paper finished product, the product quality is promoted.
