Shenhua Printing Plate and Die Pad for Bulletproofing: Special Sterile and Non-Migration Solution for Medication Blister Packaging Die Cutting

Medicine blister packaging (such as capsule and tablet blister packaging) has extremely strict requirements for the asepticity, non-migration, and precision of die-cutting consumables. It is necessary to ensure that the spring pads have no harmful residues, no odors, and no small molecule migrations. At the same time, the die-cutting precision needs to reach ±0.03mm, avoiding blister damage and drug leakage. Conventional spring pads have problems such as non-compliance with aseptic standards, easy migration, and insufficient precision, making it difficult to meet the GMP compliance requirements of the pharmaceutical industry. Shenhua Printing Materials focuses on the pain points of medicine blister packaging and creates special knife plate spring pads for aseptic and non-migration. The entire process ensures the safety and compliance of medicine packaging.

In terms of aseptic and compliance control, the selected elastic material is of pharmaceutical grade, free of heavy metals, harmful plasticizers, and odorous additives. It has passed multiple pharmaceutical industry certifications such as GB 4806, FDA, and GMP, with no small molecule migrations, no harmful residues, and can directly contact medicine blister packaging. The production process is completed in a 10,000-level clean workshop, with the entire process following aseptic operation procedures. Production equipment is regularly disinfected, and operators wear sterile work clothes to avoid dust and bacterial contamination. The finished products are packaged aseptically, with each batch attached to an aseptic test report and batch traceability code, ensuring product traceability and verifiability.

In terms of precision and performance, the spring pad uses a high-density homogeneous base material, with an elasticity rate of over 98%, a compression permanent deformation rate of ≤2%, and a thickness error controlled within ±0.02mm, meeting the precise knife lines and special die-cutting requirements of medicine blister packaging. The surface adopts a low-friction anti-sticking coating to reduce friction with the blister film, avoiding blister damage and scratches, and improving waste removal efficiency. The back adhesive is selected as a pharmaceutical-grade low-release adhesive, with no residual glue or fogging volatilization after application, and will not contaminate the medicine inside the blister. After applying this solution, a pharmaceutical packaging enterprise successfully passed the GMP compliance review. The defective rate of medicine blister die-cutting from 5% dropped to 0.1%, and there was not a single case of drug contamination caused by the spring pad.
