Precautions for the use of adhesive PP synthetic paper

Normal advertising companies will be coated with a layer of transparent PVC protective film, which is divided into three types: light film, sub-film, and fog film, one is to play a protective role, and the other is to enhance the texture of the picture.

The adhesive-backed PP synthetic paper is greatly affected by temperature, and is not resistant to high temperature, and deformation will occur at high temperature; It is also not resistant to low temperatures, which can shrink slightly and cause curling. Therefore, the general adhesive-backed PP synthetic paper is used in the KT board for short-term use. It is not suitable for long-term outdoor display of display shelves.

The market can be the best specification width is generally ,,, four conventional width, at present, Shanghai Lichuan has been able to **2 meters width of adhesive and pp paper, mainly affected by the machine. There are -1 and -2 of these sizes, please pay attention to the distinction when purchasing.

The surface of the self-adhesive label must be smooth and dense, uniform density, consistent color and luster, and good light transmittance, so as to ensure that the film absorbs ink evenly and the color difference of the same batch of printed products is small.

The thickness of the self-adhesive label should be uniform, and the strength index should be qualified. The printing pressure applied during the printing process is related to the thickness of the self-adhesive, if the thickness is uneven, the printing pressure is not uniform, which will lead to the depth and light color of the handwriting or ink on the label print. If the strength of the film is too poor, the tension of the film during the printing process will be difficult to control, which will have a great impact on die-cutting and waste discharge.

Removable adhesive PP paper has been widely used as advertising materials. Waterproof PP adhesive can be seen everywhere in life, has a strong adhesive effect, can be pasted on the wall, can also be used many times, can maintain the beauty of the poster, as well as the intact display of information. The excellent colorability, soft paper, stable physical properties and low cost of removable adhesive PP paper all meet the requirements of stickers for raw materials.

PP synthetic paper products refer to materials that can be inkjet printed on the surface of PP (polypropylene) synthetic paper as the base material through coating, adhesive, slitting, packaging and other production processes.

With its mature production process, fast production speed, continuous cost reduction, popularization of screen production technology, and numerous inkjet printing equipment, PP synthetic paper products are mainly used in advertising display boards, back panels, background walls, hanging flags, X display racks, roll-up banners, portrait stands, guide signs, partitions, POP advertising, various products and promotion models, three-dimensional structural parts, etc.

The adhesive PP synthetic paper is divided into four components, the first is the coating, which has been introduced above; the second is PP substrate, with thicknesses ranging from 65 microns to 240 microns; The third is glue, which is divided into two kinds on the market, one is water glue and the other is oil glue; Frye sells water gelatin, which has a small smell, but the viscosity is not very good; Shanfu and Lichuan sell oil glue, the glue has a pungent smell, but the viscosity is good, and the current market is dominated by oil glue; The fourth is release PET, which is to tear off the unused layer of transparent film, ranging from 12 microns to 50 microns.

This is generally called PP synthetic paper self-adhesive, which is generally composed of PP synthetic paper, adhesive and backing paper, which is visible to the naked eye.

Adhesives: water glue, hot glue, oil glue, etc., bottom paper: glassine, white background, etc.

It can be matched according to the object to be attached.
