Shenhua Printing Plate and Die Pad: Development and Application for Adapting to New Packaging Materials

As the packaging industry transitions towards greening, lightweighting and functionalization, emerging packaging materials such as degradable plastics, composite eco-friendly paper, and ultra-thin electronic packaging films have gradually become the mainstream in the market. These materials present significant challenges in die-cutting, demanding new requirements for the hardness, rebound performance, and surface characteristics of the cutting tool cushions. Shenhua Printing Materials closely follows market trends and conducts specialized adaptation research, launching customized cutting tool cushions specifically for these emerging packaging materials to address industry application challenges.

For the die-cutting needs of degradable plastic packaging materials, these materials are highly resilient and prone to adhesion. Conventional cushions often encounter problems such as material accumulation and incomplete die-cutting. Shenhua Printing Materials has developed low-adhesion and anti-adhesion cutting tool cushions, which reduce the adhesion between the material and the cushion by adding special anti-adhesion coatings on the cushion surface. They also optimize the cushion hardness to邵氏 A 45-50， ensuring sufficient cushioning during die-cutting while preventing the material from adhering to the cushion surface. A biodegradable plastic packaging company that applied this product saw a 80% reduction in die-cutting material accumulation rate and a 25% increase in production efficiency.

For the high-precision die-cutting requirements of ultra-thin electronic packaging films (thickness < 0.05mm)， these materials are highly stretchable and prone to damage， demanding extremely high uniformity in cushioning. Shenhua Printing Materials has launched ultra-thin high-rebound cushions (thickness 0.3-0.5mm)， using nanoscale elastic materials with a rebound rate of 98%， and ensuring uniform pressure transmission. This effectively avoids stretching deformation or damage to the ultra-thin film due to uneven force distribution， with die-cutting accuracy errors controlled within ±0.03mm， meeting the strict standards for electronic component packaging.

For the die-cutting needs of composite eco-friendly paper (multi-layer composite structure)， these materials have weak interlayer bonding strength and are prone to delamination. Shenhua Printing Materials has customized progressive hardness-rebound cushions， using a gradient rebound design to disperse die-cutting impact forces， reducing the risk of material delamination. At the same time， it improves the neatness of the die-cut edges. This product has been successfully applied in several high-end gift box packaging enterprises， with the delamination rate of composite paper die-cutting reduced from 5% to below 0.5%.
