在“双碳”目标驱动下，传统高耗能、高污染的造纸行业正面临前所未有的转型压力。与此同时，一种以“石头”为原料的新型纸张——PE石头纸，正悄然崛起，成为包装、印刷、装饰等领域的新宠。
Driven by carbon neutrality goals, the traditional paper industry – known for high energy consumption and pollution – is under unprecedented pressure. Meanwhile, a new type of paper made from “stone” – PE Stone Paper – is quietly rising as a star in packaging, printing, and decoration.
不砍树、不耗水、零排放，还能防水防蛀、耐撕耐用——这到底是什么黑科技？
No trees cut, zero water discharge, waterproof, insect-proof, tear-resistant – what is this black technology?生产工艺：从石头到纸张的“绿色炼金术”
Production Process: The “Green Alchemy” from Stone to Paper
PE石头纸的核心原料很简单：PE（聚乙烯）+ 碳酸钙石粉（通常为方解石、大理石等）。但要把石头变成可以书写、印刷、折叠的纸张，背后是一整套高度自动化的生产线。
The core raw materials for PE stone paper are simple: PE (polyethylene) + calcium carbonate stone powder (usually calcite, marble, etc.). However, turning stone into paper that can be written on, printed on, and folded requires a fully automated production line.
苏州金纬提供的PE石头纸成套设备，覆盖了完整工艺流程：
Suzhou JWELL provides complete PE stone paper production equipment covering the entire process:
混合造粒：将PE树脂与超细钙石粉按特定比例混合，通过高温挤出造粒，形成均匀的“石头纸母粒”。
Mixed granulation: PE resin and ultrafine calcium stone powder are mixed in a specific ratio and granulated by high-temperature extrusion to form a uniform "stone paper masterbatch".
挤出流延：母粒经熔融、挤出、流延成薄片，这是纸张成形的关键一步。
Production line overview: pelletizer → casting unit → stretching unit, which is a key step in paper forming.
收卷 & 分切：PLC电脑集成控制整线运行，速度快、精度高，成品表面光滑、厚度均匀。
Rewinding & Slitting: The entire line is controlled by a PLC computer, which is fast, precise, and produces finished products with smooth surfaces and uniform thickness.
对比传统造纸：不制浆、不漂白、不排水，每生产1吨石头纸，可拯救20棵大树，节省约10吨水。
Comparison with traditional papermaking: No pulping, no bleaching, no wastewater – every 1 ton of stone paper saves 20 trees and about 10 tons of water.
应用领域：不止是纸，更是功能性新材料
Application Fields: More Than Paper – A Functional New Material
尤其值得一提的是，石头纸在户外广告、冷藏包装、潮湿环境用纸等传统纸品“禁区”表现优异，正打开大量增量市场。
