Description

一种新塑包装箱盒用彩印复合纸板及其制作方法 技术领域 本发明涉及一种包装箱盒用复合纸板。 背景技术 传统的纸类包装箱盒成型纸板分为非彩色印刷和彩色印刷两种。 前者 材料基本以黄色牛皮纸为面材， 经过复合机与普通箱板纸 （包括茶板纸、 灰板纸、 白板纸等） 复合而成。 后者材料选用成本较高和很高的木浆类白 板纸、 白卡纸、 铜板纸等实施单张平版彩色印刷后再与以黄色牛皮纸为面 材的普通单片箱板纸进行再贴合， 制成彩印纸板， 之后再与瓦楞纸板贴合 做成纸箱； 或直接与已经制成的普通纸箱和纸盒进行再贴合。 非彩色印刷 的纸板制造成本较低， 属中低档包装材料。 传统的彩色印刷的纸板制造方 法不能解决连续的成卷彩色印刷和与普通箱板纸连片复合这两个关键环 节问题。 由于上述原因， 彩印纸箱盒的制造成本很高， 也导致高档包装品 价格较高。
随着新材料的发展， 有一种利用双向拉伸聚丙烯膜作为外层， 经过凹 轮机画面印刷的包装箱纸板， 它虽然具有防水和彩印效果， 但是仍存在着 缺点如下： 1双向拉伸聚丙烯膜（简称 OPP膜） 既便复合在白板纸上， 也 无法显现纸张的书写特点。 2在凹印机上印刷只能背印（又称底印）， 不能 正面印刷 （又称表印）， 在背印之后， 其薄膜本身只留印记， 不能单独显 现成像效果， 因此复合只能选择白板纸反衬。 3只能先印后复合， 而不能 先复合后印刷。 4在与白板纸复压时， 使用的是溶剂型胶 （又称水性胶）， 因此， 在湿式复合成型时， 很容易出现一些小的汽泡， 并影响 OPP膜的印 记显像。 5由于 OPP膜不是纸， 其背印效果因薄膜自身的横向与纵向延伸 性，会不断出现印像叠色或飘移现象。 6由于选用 OPP膜和水性胶， 因此， 它无法具备实施自动化制箱流水线作业的条件。 发明内容 本发明的目的是提供一种成本低、 性能好、 环保、 美观和适合工业化 连续生产的新型包装箱盒用彩印复合纸板及制作方法。
本发明所述一种新型包装箱盒用彩印复合纸板， 实现上述目的关键在 于： 该复合纸板由作为外表面层的具有正面印刷层的非透明聚丙烯合成纸 层和单层或多层箱板纸， 通过粘胶层复合后构成。
如上所述一种新型包装箱盒用彩印复合纸板， 所述非透明聚丙烯合成 纸与箱板纸之间为加热型聚脂胶层。
如上所述一种新型包装箱盒用彩印复合纸板， 所述单层箱板纸层是茶 板纸、 灰板纸或白板纸中的一种。
如上所述的一种新型包装箱盒用彩印复合纸板， 所述多层箱板纸层是 由第一层的茶板纸、 灰板纸或白板纸中的一种、 第二层非加热型胶、 第三 层瓦楞纸板形成的复合层构成。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法： 将作为纸 板面材的非透明聚丙烯合成纸在凹印机上进行成卷的连续彩色印刷， 再与 普通箱板纸连片复合、 或将上述作为纸板面材的非透明聚丙烯合成纸与普 通箱板纸连片复合后， 再在凹印机上进行成卷的连续彩色印刷， 制成卷装 单层彩印复合纸。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法： 将卷装单 层彩印复合纸按设定好的纸板应用规格裁切， 再多重复合后， 制成多层彩 印复合纸。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法: 所述彩色 印刷工序是在四至八色或八色以上凹版印刷机上成卷彩印完成; 所述连片 复合工序是在涂布淋膜复合机上完成的； 所述裁切工序是在经纬同步切刀 裁纸机上完成； 所述多重复合是利用箱面贴合机完成再贴合。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法： 彩色印刷 要求聚丙烯合成纸的厚度控制在 20-180 μ的范围内， 上机的油墨釆用合成 油墨， 用量应控制在平时彩色套印木浆类纸制品用量的一半至三分之一范 围内。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法： 在连片复 合时， 卷装箱板纸的厚度应控制在 60-800 μ的范围内， 在上层的聚丙烯彩 印合成纸与下层的各种普通箱板纸中的一种箱板纸之间为加热型聚脂胶。
如上所述的一种新型包装箱盒用彩印复合纸板的生产方法: 多重复合 时， 选用瓦楞纸板， 其厚度应控制在 0.2-1.2厘米的范围内； 贴合时 使用 非加热型胶。
本发明与传统的复合纸板相比， 具有如下优点和积极效果：
1 . 由于非透明聚丙烯合成纸本身不含木浆， 不含植物纤维， 无毒无 味， 可以多次回收使用， 属无二次公害的绿色产品， 因此， 以非透明聚丙 烯合成纸为面材的包装箱盒用彩印复合纸板同样具有多次回收使用的特 性， 是符合环保要求的绿色包装新品种。
2. 由于能形成连续工业化生产的成卷彩印 +连片复合式或连片复合 + 成卷彩印式的彩印纸板成型工艺流程， 从而改善了原有生产方式因非工业 流水线作业流程所造成的设备使用率和劳动功效低下及生产成本居高不 下的弊端。 '
3. 本发明成功解决了现阶段包装纸材受限于幅宽和损耗浪费严重的 现象。 凹印机的彩印幅宽本就远大于平版印刷的幅宽， 而成卷连续彩印又 使得纵向图案可以合理延长， 这就为超纸面规格的大型彩色包装箱用制品 的生产奠定了基础。 同时， 非透明聚丙烯合成纸的宽窄规格可先行依产品 订单生产， 从而会大大减少正度或大度卡纸在平版彩印时经常出现的大面 积损耗浪费现象。
4. 使用牛皮纸或白板纸做包装箱盒的纸板面纸时， 均有厚度及强度 的要求， 否则难以被压模折制 （会破裂） 成箱。 而使用本发明的方式， 不 但仅需原有纸板面纸的六分之一厚度即可承受制箱过程压折的要求。 而且 还大幅度提高了箱盒的耐压和耐戳穿性， 并节约大量的纸制品成本。
5. 由于非透明聚丙烯合成纸本身所具有的亚光特性， 使其有比高档 木浆纸张更优越的印刷性能和更亮丽的彩印效果， 从而使应用本发明制作 出的彩箱和彩盒真正具有了物美价廉的品质。
6. 经多重复合后产出的彩印复合箱板 , 不但拓宽了原有包装材料的 应用领域， 而且等于给制作彩箱和彩盒用的瓦楞纸板穿上了一层既防水、 防潮又耐酸碱、 耐压、 耐戳穿的保护外衣。
7. 由于本发明在制作方法上， 采用了与以往复合工艺不同的干式复 合法， 即选用加热型聚脂胶通过涂布淋膜复合机进行同步干式复合， 其复 合平整度、 均勾度、 牢固度均远胜于以往的湿式复合法， 是一项典型的纸 板复合技术进步。 附图概述 图 1是本发明所述一种新型包装箱盒用彩印复合纸板的一个实施例结 构示意图。
图 2是本发明所述一种新型包装箱盒用彩印复合纸板的另一个实施例 结构示意图。 本发明的实施例 本发明的层结构关系参见附图。 本发明所选用的材料均为市场所售 的， 其中最外层为卷装非透明聚丙烯合成纸， 在非透明聚丙烯合成纸表面 可通过凹版印刷机成卷彩色印刷上图形、 文字， 彩色印刷用普通的彩色合 成油墨。 非透明聚丙烯合成纸层 1与箱板纸层 3是通过加热型聚脂胶层 2 贴合在一起， 见图 1。 其中箱板纸层 3可以选用茶板纸、 灰板纸或白板纸。 图 1所示的复合纸板适合于做较小体积的彩盒。
图 2中，在箱板纸层 3上还通过非加热型胶 4贴合有一层瓦楞纸板 5。 图 2所示的复合纸板适合于做体积较大的彩箱。
本发明所述一种新型包装箱盒用彩印复合纸板的生产方法的工艺流 程分为先彩印后多重复合方式和先复合后彩印再复合方式。
―. 先彩印后多重复合方式
准备卷装非透明聚丙烯合成纸， 上八色凹版印刷机成卷彩色印刷， 上 涂布淋膜复合机与卷装箱板纸复合， 上经纬同步切刀裁纸机按所需纸板规 格裁切， 形成单层彩印复合纸板， 上箱面贴合机与瓦楞纸板再贴合形成多 层彩印复合箱板。
第一步，将某种规格的卷装非透明聚丙烯合成纸 (例如 120 μ厚、 1100 厘米宽的卷装合成纸) 装进八色凹版印刷机进料口前方的原料挂件上。 本 发明产品要求聚丙烯合成纸的厚度控制在 20- 180 μ的范围内； 宽度以不超 出凹版的印刷机的最大幅宽为限。 然后在车间常温条件下开动八色凹版印 刷机， 按已经制好的图形版样实施彩色印刷。 上机的油墨采用合成油墨， 但用量应控制在平时彩色套印木浆类纸制品用量的一半至三分之一范围 内。 同时应开启凹版印刷机上的烘干设备。
第二步， 将彩印过的成卷非透明聚丙烯合成纸装在涂布淋膜复合机的 进料通道口前的挂件上，并与挂在下侧的卷装箱板纸（例如 260 μ厚、 1100 厘米宽的茶板纸） 对齐。 本发明产品要求卷装箱板纸的厚度应控制在 60-800 μ的范围内； 宽度以不超出涂布淋膜复合机的最大幅宽为限。

第五步， 由于目前的瓦楞纸板都是片装的。 因此， 在用单层彩印复合 纸板贴合瓦楞纸板时， 应先将卷装单层彩印复合纸板按设定好的纸板应用 规格在经纬同步切刀裁纸机上裁切成片装， 然后再上箱面贴合机与片装的 瓦楞纸板进行贴合。瓦楞纸板的厚度应控制在 0.2-1.2厘米的范围内。贴合 时应使用非加热型胶。 至此， 就可以生产出多层箱用彩印复合箱板。
二. 先复合后彩印再复合方式
准备卷装非透明聚丙烯合成纸， 上涂布淋膜复合机与卷装箱板纸复 合， 上八色凹版印刷机成卷彩色印刷， 上经纬同步切刀裁纸机按所需纸板 规格裁切， 形成单层彩印复合纸板， 上箱面贴合机与瓦楞纸板再贴合， 形 成多层彩印复合箱板。
第一步，将某种规格的卷装非透明聚丙烯合成纸（例如 120 μ厚、 1100 厘米宽的卷装合成纸） 装在涂布淋膜复合机的进料通道口前的挂件上， 并 与挂 在下侧的卷装箱板纸 (例如 260 μ厚、 1100厘米宽的茶板纸) 对齐。 聚丙烯合成纸与箱板纸的厚度要求同前一种复合方式。
第二步， 在车间常温条件下开动涂布淋膜复合机， 让上层的聚丙烯合 成纸与下层的茶板纸在中间加热型聚脂胶的作用下一齐向前运动， 进而复 合成单层的复合纸板。
第三步， 将复合好的卷装单层复合纸板挂在八色凹版印刷进料口前方 的原料挂件上。 然后在车间常温条件下开动八色凹版印刷机， 按已经制好 的图形版样实施彩色印刷。 上机的油墨采用合成油墨， 但用量应控制在平 时彩色套印木浆类纸制品用量的一半以内。 同时应开启凹版印刷机上的烘 干设备。 第四步， 将彩印好的卷装单层彩印复合纸板挂在经纬同步切刀裁纸机 进料口后， 先核对裁纸机上的经纬刻度， 再按设定好的纸板应用规格开机 裁切。 裁切后的单层彩印复合纸板可以直接制做彩盒， 也可以经下一步骤 第五步， 将卷装单层彩印复合纸板按设定好的纸板应用规格在经纬同 步切刀裁纸机上裁切成片装， 然后再上箱面贴合机与片装的瓦楞纸板进行 贴合。瓦楞纸板的厚度应控制在 0.2-1.2厘米的范围内。贴合时应使用非加 热型胶。 至此， 就可以生产出多层箱用彩印复合箱板。
