Shenhua Printing Plate Knife Pad: Dust-free Paper Die-cutting Special Sterile Anti-Scraping Solution

Non-film paper (such as medical non-film paper and electronic non-film wiping paper) is widely used in scenarios such as medical dressings, precise electronic wiping, and cleanroom cleaning. Its core requirements are sterility, no dust shedding, and neat edges. During die-cutting, problems such as debris falling off, rough edges, and contamination from sterility may occur. Conventional elastic pads are prone to debris falling off, fail to meet the strict die-cutting requirements of non-film paper. Deephua Printing Materials focuses on the pain points of non-film paper die-cutting and has developed a special elastic pad for sterility and debris prevention. The entire process ensures the quality of non-film paper die-cutting.

In terms of sterility and debris prevention control, medical-grade sterile elastic materials are selected, which do not contain heavy metals or harmful residues. They have passed multiple certifications such as GB 4806, FDA, and GMP, and do not shed dust or have an unpleasant odor. The production process is completed in a 10,000-level cleanroom, with all operations carried out under aseptic conditions.生产设备 is regularly disinfected， and operators wear sterile work clothes to avoid dust and bacterial contamination. The elastic pad uses a non-filled and non-powdered formula to prevent dust shedding during use. The cutting process adopts a low-temperature precision cutting method to avoid micro-shavings caused by high temperatures. The edges are treated with a blunting and sealing process to completely eliminate debris and fraying. In terms of performance and precision， the elastic pad uses a high-density homogeneous base material with a rebound rate of over 96%， a compression permanent deformation rate of ≤3%， and a thickness error controlled within ±0.02mm. This ensures that the die-cut edges are neat and without burrs， preventing the non-film paper from tearing. The surface is coated with a low-friction anti-adhesion layer， with a friction coefficient reduced to below 0.06， reducing the adhesion between the non-film paper and the elastic pad， improving the waste removal efficiency， and avoiding coating migration and contamination of the non-film paper. We have launched multiple thickness specifications ranging from 0.6 to 1.2mm， suitable for the die-cutting needs of different thickness non-film papers， without the need for repeated adjustments. After a medical dressing enterprise applied this solution， the debris fall-off rate of non-film paper die-cutting dropped to below 0.05%， the sterility test pass rate reached 100%， the edge roughness rate dropped to 0.1%， and it fully met the sterile requirements of medical and electronic fields.
