Problems solved by technology

This kind of inkjet advertising cloth has poor adhesion fastness, and the production process is relatively complicated, resulting in low yield
Usually this kind of inkjet advertising cloth is also equipped with carbon black slurry or shading ink layer between the PVC surface layer and the PET film layer and between the PVC bottom layer and the PET film layer. Although it can enhance the light-shielding performance of the product, it also has the problem of complex production process.

Embodiment Construction

[0014] Below in conjunction with specific embodiment, further illustrate the present invention.

[0015] Such as figure 1 The shown non-net inkjet advertising cloth includes a PVC surface layer 3 and a PVC bottom layer 1, a PET film 4 is arranged between the PVC surface layer 3 and the PVC bottom layer 1, and a glue layer 2 is pre-laid on the surface of the PVC surface layer 3 and the PVC bottom layer 1, The PVC surface layer 3 and the PVC bottom layer 1 of the glue layer 2 are laid and hot-melt bonded with the PET film 4 again, and another layer of PVC black film 5 is also set between the PVC surface layer 3 and the PVC bottom layer 1 . The components of the glue layer 3 are 100 parts by weight of DINP and 10 parts by weight of adhesive. A layer of release paper is also arranged on the back of the PVC bottom layer 1, and the release paper is coated with removable glue, preferably removable acrylic glue. An air guide groove is arranged on the glue layer coated on the PVC sur...

Abstract

The invention relates to a screenless printing advertising cloth. The existing printing advertising cloth is poor in bonding fastness, and the production process of the existing printing advertising cloth is also complex, which results in relatively low yield. The screenless printing advertising cloth comprises a PVC surface layer and a PVC bottom layer; the screenless printing advertising cloth is characterized in that a PET film is arranged between the PVC surface layer and the PVC bottom layer, the PVC surface layer and the PVC bottom layer are pre-coated with a glue layer, and then the PVC surface layer and the PVC bottom layer both coated with the glue layer are fitted with the PET film by virtue of hot melting, and moreover, a PVC black film is additionally arranged between the PVC surface layer and the PVC bottom layer. The screenless printing advertising cloth has the advantages that the production process of the PET advertising material is effectively shortened and the processing steps for the PET film are reduced. The PET film is always kept flat without wrinkling during production and the rate of finished products is effectively increased.

Description

technical field [0001] The invention relates to a netless inkjet advertising cloth. Background technique [0002] Existing inkjet advertising cloth comprises a PVC surface layer, a PVC bottom layer and a PET film layer, and usually the PU glue is first applied to the PET film, and then the PVC surface layer and the PVC bottom layer are connected through the PU glue. The bonding fastness of this kind of inkjet advertising cloth is relatively poor, and the production process is relatively complicated, resulting in a low yield. Usually this kind of inkjet advertising cloth is also equipped with carbon black slurry or shading ink layer between the PVC surface layer and the PET film layer and between the PVC bottom layer and the PET film layer. Although it can enhance the light-shielding performance of the product, it also has the problem of complex production process. . Contents of the invention [0003] Aiming at the above-mentioned defects, the present invention provides a...
