食品包裝材料：環保与安全双重升级

【CPP114】訊：目前，国家食品安全风险评估中心就《食品安全国家标准 食品接触材料及制品用添加劑使用标准（行业征求意见稿）》征求意见。新国标通过删除含氟化合物、邻苯类物质等，推动纸包裝向无氟化、生物基材料转型。在此过程中，中小型纸包裝企业及相关单位或因替代技術成本承压，但头部企业和具备技術转型的包裝企业将凭借研发优势抢占新的市场。从产业链角度看，需要建立从原料到成品的全链条监控体系，以应对新标准的合规挑战。
新標准強化質量與安全
与2016年发布的《食品安全国家标准 食品接触材料及制品用添加劑使用标准》相比，新国标中与纸包裝相关的修订变化主要集中在以下几个方面。
一是删除高风险物质。含氟化合物全面禁止，修订后明确删除所有含氟聚合物，理由为高风险且行业已淘汰。这将直接影响纸包裝的防油技術，迫使包裝企业转向硅酮、丙烯酸酯等替代涂层发展。传统含氟防油剂因成本低、效果优被广泛用于食品纸盒，如快餐包裝等。禁用后需采用天然生物阻隔材料或者硅酮涂层、丙烯酸涂层技術。中小纸包裝企业短期内面临技術转型阵痛，头部企业将加速布局水性環保涂层技術。
同时，邻苯二甲酸二丁酯等从黏合剂、涂料、油墨名单中删除。这些因迁移风险被禁，纸包裝复合工艺中的黏合剂需替换为环氧大豆油、柠檬酸酯类等生物基增塑剂。成本方面，替代增塑剂价格将高出20%—40%，且可能降低黏结强度，还需调整工艺参数。
二是再生纤维素材料新增管控。新国标首次明确再生纤维素如玻璃纸等允许使用的添加劑，包括白矿物油、十二烷基苯磺酸钠等。这为再生纸包裝提供合法合规的助剂选项，推动環保包裝发展。但同时也存在风险点，需严格控制洗涤剂残留，否则易迁移至食品。
三是着色剂纯度升级。纸包裝生产使用的油墨中，炭黑需深度提纯，增加生产成本。所有着色剂的重金属杂质要求更严，影响纸包裝彩色印刷的安全性。纸包裝中铝箔复合层、金属颜料油墨需检测铝迁移量，可能限制高铝含量设计。锌、锰等元素限量同 步约束镀锌纸罐、彩色油墨的使用。

"A list of the things you are going to buy," Mary remarked. To regain the highroad we had turned into a northerly fork, and were in as lovely a spot as we had seen all day. Before us and close on our right were the dense woods of magnolia, water-oak, tupelo and a hundred other affluent things that towered and spread or clambered and hung. On the left lay the old field, tawny with bending sedge and teeming with the yellow rays of the sun's last hour. This field we overlooked through a fence-row of persimmon and wild plum. Among these bushes, half fallen into a rain-gully, a catalpa, of belated bloom, was loaded with blossoms and bees, and I was directing Camille's glance to it when the shots came. Another outcry or two followed, and then a weird silence. Ferry led Kendall and me into the woods, the other two remaining. We found rising ground, and had ridden but a few minutes when from its crest we looked upon a startling sight. In front of us was a stretch of specially well farmed land. Our woods swept round it on both sides, crossed a highway, and gradually closed in again so as to terminate the opening about half a mile away. Always the same crops, bottom cause of the war: from us to the road an admirable planting of cotton, and from there to the farther woods as goodly a show of thick corn. The whole acreage swept downward to that terminus, at the same time sinking inward from the two sides. On the highway shone the lighted rear window of a roadside "store," and down the two sides of the whole tract stretched the hundred tent-fires of two brigade camps of the enemy's cavalry. Their new, white canvases were pitched in long, even alleys following the borders of the wood, from which the brush had been cut away far enough for half of them to stand under the trees. The men had quieted down to sleep, but at one tent very near us a group of regimental officers sat in the light of a torch-basket, and by them were planted their colors. A quartet of capital voices were singing, and one who joined the chorus, standing by the flag, absently yet caressingly spread it at such breadth that we easily read on it the name of the command. Let me leave that out. "Quite so. The man was all twisted from his hip, and he had a crooked nose." They were all flying from the plague, which was spreading, and emptying the bazaars and workshops. The Exchange being closed, trade was at a standstill, and the poor creatures who were spared by the pestilence were in danger of dying of hunger. “But she knew them,” objected Dick. “She wouldn’t throw over the wrong ones and she couldn’t get the right ones.” “That’s what we thought.” "Well, if I had sich a name as that I wouldn't expect people to git it right. There's no sense in havin' a Dutch name that makes your tongue crack like a whip. Well, this Mr. McFillemgoody is Si's boss, and he writes a nice letter, and says Si done so well at Chickamaugy that some other boss—a Colonel or Corporal—" "It is not good to be free," he said at last, in a reasonable, weary tone. "In the cold there is a bad thing. In the rain there is a bad thing. To be free is to go to these bad things." "To London!" HoME免费看一级a视频ENTER NUMBET 003www.huwaifood.com.cn
