With the increasing global environmental protection voice, the application of recycled paper in the packaging industry will become more and more extensive. And the paper dust generated by die-cutting in recycled paper is much more than that of virgin paper. Especially in food packaging, hygiene product packaging, and medical product packaging, paper dust must be controlled within certain limits. Under the premise that the paper has been selected, the use of a suitable die cutter and rebound sponge can effectively reduce die cutting dust. Even on the blades of general high-end die cutters, if observed with a magnifying glass, there are still many pores and rough surfaces, that is, they are not smooth, which is one of the reasons for the generation of paper dust. Austrian Bohler (Bohler) company provides a "Supreme Supreme Knife", using a special metal coating, like the wall, fill the air holes and rough surface layer to achieve an excellent smoothness, so as to effectively reduce Paper dust. Due to the reduced friction between the blade and the edge of the paper, the knife itself is more durable and lasts longer.
"Silking" is also a phenomenon that occurs frequently during die cutting. One of the reasons is that the die cutting blade cannot withstand a large die cutting pressure. The blade becomes dull at the beginning of the die cutting, and the subsequent die cutting is actually "Crushed" instead of "cut off", the blunt side of the blade pressed silk on the paper. This phenomenon is more likely to occur when the surface of the paper is coated with varnish. The improvement method is to scientifically adjust the die-cutting pressure to prevent the pressure from being too large, and then adopt a die-cutting knife with special blade hardening and hardening, such as Universal series. If it still does not work, it is recommended to use a higher grade "Super Supreme Stabilo Tibetan Blade". This blade is treated with more elaborate blades to make it more restrained, and its blade pressure resistance is several times higher than other blades. Can effectively prevent the occurrence of silking phenomenon.
