Do you use pp paper or coated paper? I can only tell you the difference between them. PP paper is a kind of synthetic paper, which is made by mixing and pressing polypropylene resin, polyethylene resin and natural stone powder. Synthetic paper and pearl paper not only have waterproof, durable and unbreakable plastic properties that natural paper can't achieve, but also have excellent printing adaptability of natural paper, which can be widely used in letterpress printing, lithography, gravure printing and screen printing. PP paper can be used as photo adhesive, that is, "adhesive-backed PP synthetic paper", which can be used in advertising, printing and so on, and has a wide range of uses. In addition to PP substrate, there are also base papers, such as coated paper or matt paper. These papers are mainly offset printing technology, suitable for mass production. Of course, some base paper has now been processed for photography. Simply put, the poster covers part of PP paper. What is the poster material you want to adopt? Poster material recommendation 1. The poster material is made of PP paper. 2. The material of 2.PP paper is similar to the photographic paper developed in the photo studio. The material is slightly thinner and covered with a waterproof film, which is suitable for advertising posters and commercial posters. 3. The commonly used materials for posters are: non-woven fabrics, spun silk fabrics, PP paper (commonly known as stickers) and photographic paper. 4. Non-woven fabrics are thick, granular, three-dimensional, not afraid of folding and curling, and can recover quickly. Silk cloth is smooth, light, soft and vertical, which is suitable for wedding ceremony posters. 5. The material of photo paper is similar to that of photo studio, but it is thicker and covered with a waterproof film, which is suitable for making animation posters, high-precision digital life photos and so on. Is the poster made of photographic paper or PP glue? Photographic paper and PP glue have their own characteristics, mainly depending on where the poster is hung. Photographic paper is brighter than pp, such as coated paper, which is more durable but thinner than photographic paper. PP glue and photographic paper are indoor photographic materials. These two materials are waterproof, sunscreen and brightly colored, and both need a film to prevent fading. Then the difference between these two materials is that PP paper is a kind of synthetic paper, which is a common printing material for photo machines and is also very common in advertising materials. PP paper is made of polypropylene resin, polyethylene resin, natural stone powder and other main raw materials by mixing and pressing. Its product is characterized by being made of plastic material imitating paper, without using any forest resources, and replacing natural paper with functionality. Synthetic paper not only has waterproof, durable and unbreakable plastic properties that natural paper cannot achieve, but also has excellent printability of natural paper. Can be widely used in relief printing, lithography, gravure printing, screen printing and other post-processing fields such as bronzing, embossing, cutting, drilling and origami. PP paper can be used as photo adhesive, that is, "adhesive-backed PP synthetic paper", which can be used in advertising, printing and so on, and has a wide range of uses. Photographic paper is often used in advertising materials and photography, and it is also a printing material commonly used in photo machines. All kinds of photographic paper coated with photosensitizer. Quantitative120 ~ 200 g/m. The paper is smooth and white, with high smoothness and good dimensional stability. Made of cotton pulp or high-purity bleached chemical wood pulp. Thick paper with certain wet strength and acid and alkali resistance. Photographic paper can produce brighter and brighter images than ordinary adhesive-backed PP synthetic paper, because it has higher gloss, brighter colors, higher image resolution, stronger anti-aging performance and better overall effect than PP paper.
