食品包裝材料：環保与安全双重升级

推出替代技術刻不容缓
鉴于新国标的调整优化对食品纸包裝的影响较大，尤其是现有的食品级汉堡纸、纸浆模塑餐包等應用领域。这需要纸包裝企业和产业链尽快找到应对策略。在目前的食品级防油原纸和纸浆模塑餐包生产中，表面施胶和浆料配制中均会添加含氟防油剂以达到终端使用的功能要求。但根据目前的更新内容，已明确说明拟删除的物质包括“高风险物质或行业已淘汰品种”及“无添加剂功能的物质”。而含氟防油剂因高风险特性被归类为淘汰对象。根据新国标征询的时间节点，此次调整最快将于明年发布，过渡期应该也会设定，但对于相关纸包裝企业和上下游产业单位来说，推出无氟替代技術已刻不容缓。
汉堡纸或防油卡紙相关的生产企业，可考虑采用生物质防油材料，及采用水性丙烯酸乳液替代。如果采用机内涂布或施胶的方式，还需要解决损纸回抄和黏辊等抄造问题，确保回收打浆的顺利实现。具体的應用工艺技術参数，需要根据企业实际情况灵活确定，包括施胶方式和配方设定，都要从实验室到上机的多次验证中落地。未来重点在于如何通过配方和産品组合来优化成本和实现企业的顺利應用。
纸浆模塑领域主要以餐包为主，从传统浆内配料工艺看，防水剂已大量使用，而配套使用的浆内含氟防油剂，则在过去欧美禁氟的带动下，推出了许多替代方案。如目前已成熟使用的蜡基水性无氟防油剂，基本能够满足20℃—60℃防油温度的场景，但低温和高温依旧是目前行业较难实现的技術壁垒。新国标开始禁氟，将直接推进餐包行业迅速开展替氟材料的工作。无氟防油方案预计将在未来2到3年内成为市场最关注的話題，相关上下游企业将大力推进相关産品和技術方案的落地。
按照新国标要求及供應链合规审查的程序，未来食品纸无氟标准的推进和氟化合物检测方法的确认，将成为产业链发展的重中之重。相关检测单位也需要加强无氟测试能力，特别是需要开发出简单可行的检验方法。

"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 003zcep.com.cn
