Shenhua Printing Plate Knife Pad: Upgrade to biodegradable material, creating a full life cycle green and environmentally friendly solution

With increasingly strict global green environmental policies, the printing and packaging industry has upgraded its requirements for consumables from "recycling" to "originally degradable". Traditional non-degradable rubber pads are difficult to naturally degrade after being discarded and their long-term accumulation can cause environmental pollution, becoming an obstacle to enterprises' green transformation. Shenzhou Printing Materials closely follows the environmental protection trend and has launched degradable knife plate pads. Through the research and optimization of bio-based materials, it achieves "efficient use and environmentally friendly disposal", helping enterprises complete their green transformation.

In the research of degradable materials, Shenzhou Printing Materials abandoned traditional synthetic rubber and selected bio-based degradable elastic materials. Using corn starch and natural rubber as core raw materials and adding degradable accelerators, the pads can be completely degraded in the natural environment (at a temperature of 25℃ and a humidity of 60%). The degradation rate is over 90%, and the degradation cycle is controlled within 180-270 days. After degradation, there are no harmful residues and they can be converted into organic fertilizers, truly achieving "originating from nature and returning to nature". At the same time, through formula optimization, the core performance of the degradable pads is not inferior to that of conventional pads. The rebound rate is ≥ 92%, the compression permanent deformation rate is ≤ 6%, and the service life can reach over 80% of that of conventional pads, fully meeting the requirements of common cutting scenarios.

In terms of environmental compliance, the degradable pads have passed the EU OK compost degradable certification and the US ASTM D6400 degradable standard certification, meeting the requirements of green packaging consumables at home and abroad. They can be directly used in scenarios with strict environmental protection requirements such as food, medicine, and environmental protection packaging. According to different cutting needs, a degradable pad classification scheme has been launched: high-end precision cutting is suitable for degradable precision grade pads, common cutting is suitable for degradable general grade pads, and low-cost requirements are suitable for degradable economic grade pads, meeting the green transformation needs of different customers.

After an environmental packaging enterprise applied this degradable pad, it successfully passed the green packaging certification, significantly improving its export competitiveness. At the same time, the used pads do not require special environmental protection treatment, and it saves nearly 10,000 yuan in environmental protection costs annually, achieving a win-win situation of economic benefits and environmental benefits. Shenzhou Printing Materials' degradable pads not only respond to the call for green development but also help enterprises seize the initiative in the environmental protection consumables market.
