欧盟委员会已与2025年11月27日正式发布战略指导《构建具竞争力与可持续性的欧盟生物经济战略框架（最终版）》。但这仅仅是风暴的序曲。在 其身后，是一套精密咬合的法律"组合拳"正在收网：《欧盟生物技术法案》（EU Biotech Act）正加速生物制造的市场准入与监管沙箱落地；《包装 与包装废弃物法规》（PPWR）划定了严苛的回收红线；《生态设计法规》（ESPR）强制推行数字产品护照；而《反洗绿指令》（Green Claims Directive）则开启了对环境数据的穿透式审计。特别是根据最新立法时间表，欧盟将于2026年期间实施针对生物基塑料的碳足迹核算细则 （Delegated Acts），并同步启动对食品接触材料"微塑料释放"的合规性立案审查。 第三，"减塑"红线难越。PE淋膜本质上并未脱离"塑料"范畴。随着欧盟PPWR等法规对包装中塑料含量的严格限制，这种"纸+塑"的过渡性方案正面 临政策红线的挤压，注定无法成为长期的合规解决方案。 定义 2.0 标准：生物基水性涂层的"降维打击" 在中国"十五五"即将开局的当下，这场源自欧洲的规则重构，引发了中国造纸与包装行业深刻的冷思考：如果用这把来自国际市场的" ...

本周要闻回顾：重视煤价四段轮推断，稳煤价依旧 动力煤方面：动力煤价格小跌，截至12月5日，秦港Q5500动力煤平仓价为785元/吨，环比下降31元/ 吨，广州港价格为825元/吨，目前已经完成我们提示的煤电盈利均分的750元价格目标。煤价虽有降低 趋势，但预计未来也将逐步恢复至我们预计的第四目标价格区间，即800-860区间。另外，虽然近期动 力煤价有所回调，但整体上涨趋势不变，价格仍主要受到供给持续收紧和需求继续放量的双重影响。其 中供给收缩是自7月严查超产行动的延续，叠加11月中央安全生产考核巡查推进，使得产能释放进一步 受限；而需求上升是由于近期能源进入需求旺季，北方多地由于新一轮寒潮来临而提前供暖，工业生产 也推进到了年底冲刺阶段，各种工厂的煤炭需求均有大幅增长态势。炼焦煤方面：截至12月5日，京唐 港主焦煤报价1630元/吨，从七月初的1230元的底部反弹；焦煤期货反弹更为明显，从6月初的719元反 弹至当前的1140元，累计涨幅达到58.6%；炼焦煤价格随着动力煤价格的波动而波动，在2.4倍比值有非 常明显的规律。 开源证券近日发布煤炭行业周报：动力煤价格小跌，截至12月5日，秦港Q5500动力煤 ...
