PEPA 1. PEPA basic knowledge of the composition and structure of PEPA same plain white paper, that is, from the underlying fibers, fillers, and surface coating of three parts. Plain white paper with a surface coating of different particles form in pearl effect. Such particles are composed of titanium dioxide (or other metal oxides) and mica particles, mica particles are titanium dioxide (or other metal oxides) to form a pearlescent wrapping paper, the structure in a thin sheet. 2. PEPA ⑴ low surface energy characteristics, poor adsorption properties of the ink surface of the sheet structure due to the mica and titanium dioxide (or other metal oxide) is smooth, and the paper during the papermaking process require a relatively smooth (such pearlescent effect to better through the coating into the eye), resulting in pearl paper surface than ordinary white paper can be much smaller, easy attachment when printing ink absorption, is not easy to dry. ⑵ surface susceptible to damage 3. pearl pearlescent effect often have problems printing paper ⑴ ink adhesion and drying properties caused by bad low density printing field, a small dot loss, slow drying, easy to stick negative dirty, easy bruising and so on. ⑵ easily lost pearl effect, printing is easy to form white spots, blur, creases and other phenomena. 300 g and 250 g pearl paper art paper printed greeting cards, paper that good? Not necessarily. In fact, there are many kinds of printing paper 250g pearl paper, for example, coated matte paper recycled paper (categories) specialty (categories, sub-N under a variety of paper, pearl paper is one of them), and so the book paper. And the number of grams of each paper have different pearl paper company, also points pearl pearl imported and domestic pearl, pearl imported French and other places also points 300 pearl paper, also known as ice white pearl, gold and silver also divided, pearl paper company _ million Nobuhiro Paper (certified) _ pearl paper provided by the Dongguan City billion Nobuhiro Paper Limited.
