Care products articles Post Opened a Post Stamp book is actually a disturbance, and is subject to external factors into harmful. To protect postal articles is the impact of external adverse factors reduce to a minimum. Germany has always been known for rigorous, little care is the German postal supplies products for advanced. China 1999 World Philatelic Exhibition in the Old Post, fans have heard the two talk about "If your stamp accompanied by lighthouse stamp books on Qi," and can see the lighthouse stamp books to the people of the Post. The author describes various types of care in this 11 Post articles, and more domestic products and the German Lighthouse (Leuchtturm), linda (Lindner) and the American security company (Safe) companies and other foreign products difference between the performance indicators, and realistically look the gap between domestic supplies protection-mail. Illustration of some of these products from brochures, to thank in this together. Protection pouch (Wheel) Perfectly preserved ancient collectors of stamps is hard to pursue. But because technology constraints, the effect of previous forms of protection are not satisfactory. Bit by bit from the nursing-mail technology advances can see the previous efforts and the heavy price. Early in the book will be posted directly on the stamp, and later invented the glue on paper??? One side with a thin plastic strip: half of stamps affixed to the back half of the book posted on the Post, as required bonding dampened with water, and many early stamps back were so damaged. Then and later retaining pouch, stamps into the bag, but the glue coating on the back of the bag in nursing: a slight improvement, it may be a revolutionary advancement. Even though the invention of protection pouch, improve and not stagnate: start using the cellophane, place with adhesive stamps are still easy. Protect the quality of postal articles is the core of good or bad contact with the transparent plastic films of stamps, stamp it determines the stability of the long-term well-preserved, but often ignored. Not all films are safe, as not all of the plastic film can be installed as food. Philatelic films are generally used specially developed, requiring non-acidic, non-softener, non-stick stamps loss, high stability, while anti-mildew, dust-proof, breathable, moisture-proof, antistatic. The films surface should be smooth to reduce the appearance of visible mold, the outside should be slightly rough, to prevent reflection; transparency should be appropriate to facilitate the stamps. Permeability to prevent moisture do not emit. Antistatic properties, not of dust. Friction to ensure proper email book upside down and the stamp is not falling. These characteristics made little mention of protection pouch, which is the soft underbelly of domestic care products Post. No research in this area, there is no specific protection pouch film, China can not really protect postal supplies raise the level to create an international brand image. Our care bags generally used in conjunction with the insert pages, but more of a marshalling foreign exhibition, and is not used for long-term preservation of stamps. Foreign protection pouch is a long strip, the width of a certain, highly varied, as necessary the use of special cutting blade. Back coated with special glue, is designed specifically for the exhibition. The other is cut to a fixed size, retaining pouch is made this style, adapted to the single pieces of my stamp vote. Because of the lack of statistical proportion of all varieties, often have run out of common specifications, Other The left many people no choice. Later, a specification of a package, finally solved the problem. The most popular black / transparent protection pouch sealed on three sides, airtight, moisture or absorb moisture stamps can not be distributed in time to go out and put it into a period of time will form a white mark near the perforations, can be determined is the mold, but also Slow growth is almost inevitable. It is not because the production of stamps, post office to get a new email into the bag, not even used the bag, only a suitable distance, mold-prints will be generated there. According to sampling conditions and long observation, there a few years later when the prints, stamps will lose luster. Protection of such material is not suitable for bags used to hold stamps, stamp is invisible killer, because the material, water vapor permeability, absorption of the. Unfortunately, the domestic most collectors still use the bag. We can remove the packed in such bags of stamps, checks are not white retaining pouch perforation prints and stamps are not lost its luster. There are also a bag with another material, relatively thick, relatively smooth surface, put the stamp does not appear visible mold, but found that adhesion to each other between protecting bag.
