The difference between self-adhesive and back-adhesive, PP paper and PP back-adhesive paper

1. Self-adhesive:

The bottom of the sticker can be torn off, so long as the bottom paper is torn off, it can be attached to other items.

use:

1. Paper-type self-adhesive labels. Mainly used for medium and high-end daily chemical products.

Price tags, envelope address labels, medical labels for the pharmaceutical industry, and electronic and electrical labels for the electronic and electrical industries.

2. Film type self-adhesive labels. Commonly used PE, PP, PVC and some other synthetic materials, film materials are mainly white, matte, and transparent.

2. Adhesive:

Adhesive: In fact, it is an adhesive layer, a backing paper, no face material, (similar to self-adhesive, but lacks the face material)

The backing paper is generally coated with silicone oil on both sides, so the adhesive layer can be torn apart, but the self-adhesive adhesive layer cannot be torn. The back adhesive is mostly used as a viscose, usually in rolls.

The difference between self-adhesive and back adhesive:

To make an image metaphor, the self-adhesive is actually transparent glue, but the surface is printed with pictures and texts;

The self-adhesive can be used to print pictures. The back-adhesive is just a glue, similar to double-sided tape, the back-adhesive is generally used in conjunction with PP paper. It is used to bond two unbonded products together. The adhesive size is large, generally used for poster posting, and the sticker size is small, generally used for item labels.

3. PP paper:

PP paper is photo paper, photo paper is a piece of white paper that can be attached with pictures and texts, and does not have the posting function.

Sometimes used as a packaging bag for items.

4. PP adhesive paper:

What is pp adhesive paper: it is pp paper with glue on the back,

This is similar to a self-adhesive, so its alias is: self-adhesive. It is also called adhesive photo.

The PP adhesive paper looks like a sticker. It can be printed on the front and can be pasted after tearing off the transparent film on the back. The thickness is twice the thickness of the stickers on the general market.

The difference between the two:

Peel off a layer of transparent paper behind the PP adhesive paper and stick it directly, but PP paper does not have it, so you need to add the adhesive yourself.

It can also be said that photo-adhesive paper can be pasted directly, while photo paper cannot be pasted directly.

Common points:

Both of these are indoor materials, which are easy to fade under the sun.

1. The ink used for printing is the same: water-based inks are often used, which are not easy to fade, but will be water-soluble, so they have to be coated, bright film or sub-film.

2. Same purpose: photo and adhesive photo are usually used for indoor screen production, roll-up banner, X display stand, exhibition board, also can be used as wall background, poster, interior decoration painting, various banners, advertising .

It can also be used for overlays, KT boards or cold boards to produce pictures, and splicing is needed for larger surfaces.

Different paper

1. pp adhesive paper

According to the coating, it is suitable for three kinds of ink printing: eco-solvent ink, pigment ink and dye ink. Among them, the adhesive PP printed with eco-solvent ink is often called outdoor adhesive or oil-based adhesive, which can be used outdoors without laminating; for pigment ink printing, it is called waterproof adhesive on the market, and it can only be used indoors without laminating; Dye inks are printed with water-based adhesives and are not waterproof. The coating melts when it meets water, so it must be covered for indoor use.

2. pp synthetic paper

Synthetic paper is made of chemical raw materials such as olefins and added with some additives. It has soft texture, strong tensile strength, high water resistance, light resistance, cold and heat resistance, and resistance to chemical corrosion without environmental pollution. , Good air permeability, widely used in the printing of high-end artworks, maps, picture albums, high-end books, etc.
