Shenhua Printing Plate and Die Pad: The Core Guarantee for Large-scale Cutting in Medical and Pharmaceutical Packaging

Medical pharmaceutical packaging is the most stringent sub-segment in the printing packaging industry. Drug blister packaging, sterile medical device packaging, in vitro diagnostic reagent packaging, and medical labels are the core barriers that safeguard the safety of drugs and medical devices and prevent external contamination. They directly affect the life and health of patients. Therefore, the entire production process of medical pharmaceutical packaging must strictly follow GMP standards and the ISO 13485 medical device quality management system. The cleanliness, precision, batch stability, and compliance of the die-cutting process all have nearly extreme requirements. Any minor defect could lead to the failure of the packaging's sterile barrier, causing drug contamination, device failure, and even serious medical safety accidents.

In the die-cutting process of medical pharmaceutical packaging, the die-cutting pad, as a core consumable, its performance and compliance directly determine the compliance and quality of the packaging production. After 22 years of deep research in die-cutting consumables, Shenhua Printing Materials has created a matrix of medical-grade dedicated die-cutting pad products, built a cleanroom with a thousand-level cleanliness, and achieved full-process compliance control and traceability from raw materials to finished products. It has become a designated compliant supplier for dozens of leading pharmaceutical companies and medical device manufacturers in China, safeguarding the safety bottom line of medical pharmaceutical packaging with ultra-precise and rigorous products.

The die-cut production of medical pharmaceutical packaging has four non-negotiable core requirements for die-cutting pads, and traditional universal die-cutting pads completely cannot meet these strict requirements, becoming the compliance bottleneck for many medical packaging production enterprises. Firstly, the cleanliness and particle control requirements. Medical packaging production must be completed in a clean workshop. Traditional die-cutting pads are mostly made of ordinary rubber materials, which are prone to dust during production and powder shedding during use. This not only pollutes the clean production environment but also adheres to the packaging surface, bringing risks of drug and device contamination. It completely fails to meet the GMP clean production requirements.

Secondly, low leaching and environmental compliance requirements. Medical pharmaceutical packaging has zero tolerance for harmful substances. Traditional pads contain a large amount of plasticizers and fillers, which release VOCs and small molecule harmful substances, not only polluting drugs and medical devices but also failing to pass ISO 10993 biocompatibility testing and FDA food and drug contact certification, preventing enterprises from passing medical industry compliance reviews.

Thirdly, extreme precision and batch stability requirements. For die-cutting of drug blister packaging and sterile Tyvek packaging, the die-cutting pad needs to maintain stable rebound performance in tens of thousands of consecutive die-cutting processes, ensuring uniform and consistent die-cut depth, while completely cutting the substrate without puncturing the sterile sealing layer. Traditional die-cutting pad production processes are rough, with large deviations in thickness and hardness between batches, prone to permanent deformation due to compression, resulting in uneven die-cut depth, either failing to penetrate the packaging material or puncturing the sterile sealing layer, causing the entire batch of products to be scrapped, resulting in huge economic losses.

Fourthly, disinfection resistance requirements. The tools and auxiliary materials used in medical packaging production need to be disinfected regularly. After being disinfected with ethylene oxide or gamma radiation, traditional die-cutting pads are prone to aging, rebound failure, and material degradation, unable to meet the disinfection requirements of medical production, resulting in unstable pad performance and affecting die-cut quality.

In response to the core pain points and compliance requirements of the medical pharmaceutical industry, Shenhua Printing Materials has created dedicated die-cutting pad products fully compatible with medical pharmaceutical packaging production from four dimensions: production environment, formula research, forming process, and quality control management. It has achieved full-dimensional compliance adaptation. In production control, Shenhua Printing Materials has built a thousand-level clean workshop. Medical-grade die-cutting pads are completed from raw material input, production processing to vacuum packaging throughout the clean environment, eliminating secondary pollution during the production process. At the same time, a strict clean control system was established. Before each batch of products leaves the factory, they undergo strict particle size and cleanliness tests to ensure that there is no dust or shedding during production and use, fully meeting the GMP clean production requirements.

In terms of formula development, Shenhua Imprint Materials has launched a medical-grade ultra-high purity low-release special formula. It uses high-purity medical-grade polyurethane base materials, without plasticizers, fillers, or volatile substances. The VOC release is far below the limit of the medical industry standard, with an extractable ion content of less than 1 ppm, completely eliminating dust shedding and small molecule release. It has passed ISO 10993 biocompatibility testing and FDA food and drug contact certification, fully meeting the GMP production norms and compliance requirements for medical packaging. This eliminates the pollution risks of drugs and medical devices from the source. At the same time, Shenhua Imprint Materials has optimized the disinfection-resistant special formula.
