Shenhua Printing Plate and Die Pad: A Precisely Tailored Solution for the Trend of Lightweight E-commerce Packaging

With the rapid development of the e-commerce industry, lightweight packaging has become a core trend in the sector - ultra-thin cartons, lightweight labels, foldable cushioning packaging, and other new lightweight materials are widely used. These materials are thin in thickness, have high strength, and have a low tolerance for die-cutting errors. The accuracy of the cutting die plates and the buffering performance are challenged by these materials. Shenhua Printing Materials closely follows the trend of lightweight packaging and has launched targeted solutions to address the cutting problems of lightweight materials.

For the cutting requirements of ultra-thin e-commerce cartons (thickness 0.3-0.5mm), conventional elastic pads are prone to causing the cartons to collapse and the edges to deform due to excessive pressure. Shenhua Printing Materials has customized ultra-thin and highly precise elastic pads (thickness 0.8-1.2mm), using nano-level elastic materials, with a thickness error controlled within ±0.03mm, ensuring uniform pressure transmission; at the same time, the hardness of the elastic pads is adjusted to邵氏 A 45-50， achieving a "precise cutting， no collapse deformation" cutting effect. After being applied by a certain express delivery carton enterprise， the defective rate of ultra-thin cartons for cutting decreased from 8% to 0.8%， fully meeting the packaging standards for e-commerce logistics.

For the cutting requirements of lightweight self-adhesive labels (film thickness < 0.1mm)， the labels are prone to problems such as waste rejection sticking， edge burrs. Shenhua Printing Materials has developed anti-adhesion high-rebound ultra-thin elastic pads， with the surface treated by anti-adhesion coating to reduce the adhesion to the label film； at the same time， through material formula adjustment， a 98% high rebound rate is achieved at a thickness of 0.5mm， ensuring that the labels quickly detach from the elastic pads after cutting， and the waste rejection efficiency is increased by 30%. This product has been widely used in the cutting production of e-commerce express labels and product labels.

For the cutting requirements of foldable cushioning packaging (honeycomb paper core， corrugated core paper)， these materials have weak interlayer bonding force， and are prone to layer separation and tearing problems. Shenhua Printing Materials has launched gradient rebound elastic pads， through the design of elastic pad thickness gradient， to achieve progressive transmission of cutting pressure， to disperse the interlayer stress of the materials， and avoid layer separation and tearing； at the same time， the anti-slip patterns on the surface of the elastic pads enhance the adhesion to the cutting die plate， ensuring precise folding line cutting and improving the folding forming efficiency of the cushioning packaging.
