It is the world's popular environmentally friendly packaging paper. Its paper is soft, has a cortical feel, and the surface layer is wear-resistant and folding-resistant. It uses environmentally friendly water-based inks. It has a variety of colors and patterns. The combination of different colors, lines and gloss makes the paper kaleidoscopic, Quaint or fashionable, the product is suitable for all kinds of high-end packaging such as gift boxes, jewelry boxes, jewelry boxes, books, albums, high-end gift boxes, wine boxes, tea boxes, notebooks, bags, collectibles, etc.
Leather filling paper is roughly divided by material, and can be divided into: PVC filling leather paper, PU filling leather paper, raw wood pulp dip filling leather paper, domestic filling leather paper, etc .:
1. PVC filling paper
It is made of PVC (polyvinyl chloride) film on the paper base and pressed with various imitation leather textures. This product was first produced in South Korea. At first, it did have a heavy plastic smell, which is not environmentally friendly, but it also Can pass the ordinary SGS environmental protection eight requirements, but can not pass the more stringent EU countries REACH and ROSH environmental testing, its environmental protection is mainly concentrated in odor and non-degradable aspects, even developed countries can also export, but There is a need to pay heavier tariffs than normal environmentally friendly products. Generally, developed countries have the principle of who uses who recycles, so heavier taxes will be levied as a modulation. Inspection method, the film with PVC film or PU paper peeled off with a film on the surface by hand, but the paper peeled off is not necessarily the real environmental protection paper, which is related to the chemical composition and filler used in the paper itself It has a lot to do with the use of environmentally friendly and degradable chemical materials as additives and fillers, and it shows that the use of environmentally friendly water-based inks can basically be regarded as environmentally friendly paper. The use of non-environmentally friendly materials for that ingredient can not be regarded as environmental protection paper. At best, it can only be regarded as paper, and it is not allowed to be used on food packaging.
At present, there are already foreign PVC filling paper manufacturers producing no pungent odor filling paper, and most of the non-toxic materials are used. The current PVC filling paper has improved a lot compared with a few years ago, but due to its use The non-degradability of the material determines that it is never an environmentally friendly product.
2. PU filling paper
Its characteristics and production process are basically the same as PVC filling paper, but the surface material is not PVC, and it is replaced by PU film material, which is a new product that has only become popular in the past two years. Similarly, there are manufacturers who label their products as environmentally friendly products, but they are also non-degradable and not really environmentally friendly.
3. Dip-fill paper
Long fiber paper made of pure wood pulp is processed by special chemical materials and special dip dyeing process. It is a non-woven woven cellulose paper with polymer film. It is based on long tough fibers and is color coated. Cloth and embossing, a kind of paper with artificial skin made of water-soluble coating. It was first developed and produced by Switzerland and the United States. Up to now, domestic manufacturers have produced leather-filled paper using it as a sample, which is copied and improved. The quality is still the best imported from the United States.
Its characteristic is that the color is saturated and bright, it is not easy to fade, the paper is soft, good toughness, tear resistance, tensile resistance, scratch resistance, easy to glue, easy to fit, and it has the noble and texture of leather, and the price is comparable to leather and PU low. The paper is completely translucent, which can prevent it from being mounted on the zygote and showing the edges. The box looks strong and the lines are regular and beautiful.
Subsequent processing techniques can include: bronzing, silk printing, bumping, UV, die cutting, etc.
Uses: Widely used in packaging materials such as gift boxes, notebooks, book bindings, etc.
4. Domestic paper filling
The paper is made of ordinary paddle paper, which is color coated and embossed on the surface, and the surface is coated with a water-soluble coating. The paper is a kind of artificial leather. The surface is the same as the dip-filled paper paper. There is no big difference. The largest The difference lies in the paper quality. Dip-filled leather paper is soft, good in toughness, tear-resistant, tensile, scratch-resistant, easy to glue and easy to fit. The domestic paper is similar to ordinary black cards because of its base paper The paper is processed, and the paper has not been subjected to special dip dyeing treatment, so the paper is hard, the tear resistance is poor, and it is easy to have creases, it is not easy to glue and eat glue, and it is easy to roll up after glue. Mounted on the box is easy to foam and so on. Although it has many shortcomings, the price is lower than that of dip-filled paper, and it is easier for everyone to accept.
