一种全回收环保包装结构及其制作方法 技术领域
本发明涉及包装领域,尤其应用于快递、邮政以及物流领域,具体地说,涉及一种全部采用环保材料制造的全回收环保包装结构及其该包装结构的制作方法。
背景技术
如图1,在物流,快递,邮政业的包装领域,特别是具有缓冲结构的包装结构中,其中的缓冲材料A一般采用塑料板、塑胶泡A1,而塑料板和塑胶泡A1又无法直接与纸质包装结构内壁粘连,需要借助热塑的方式首先在内壁上热塑塑料覆膜B,然后再将塑料板,塑胶泡A1粘连在塑料覆膜B上。在回收再利用时,又需要撕下塑料板,塑胶泡A1以及从内壁上分离塑料覆膜B,然而塑料覆膜B极薄,难以分离,从而导致无法回收。例如:现有市场上普遍使用的一种牛皮纸气泡袋,其袋体是牛皮纸,在牛皮纸的一侧具有塑料覆膜B,在塑料覆膜B上设置了塑胶泡A1,而塑胶泡作为缓冲材料A。其中的塑料覆膜B无法分离,塑胶泡A1也无法分离,所以就会导致牛皮纸气泡袋无法回收,无法自然降解,从而污染环境。
如图2,在另外一些情况下,缓冲材料也有采用将其他可收回的材料研磨、切割形成粉末状、颗粒状的松软结构C,在包装结构生产时,将这些的粉末状、颗粒状材料填充,作为缓冲。但是这样的生产过程和工艺,会导致生产环境所在的空气中粉末严重超标,设备要求高,给工作人员健康带来潜在伤害。

第一面以及重叠于所述第一面上的保护层;
所述保护层包括至少一层衬垫,所述衬垫是纸质材质经模切后拉伸形成的网状结构。
本发明公开的全回收环保包装结构的保护层起到保护缓冲作用的保护层,其中保护层包括至少一层衬垫,通过设置模切拉伸成网状的衬垫作为缓冲。整个平面结构均采用纸质材料制成,克服了现有技术中在回收时还需要分离的问题。
再有模切纸与第一面的材质均是纸质材质,可以混用,备料简单;当纸质材质模切后形成模切纸,该模切纸还可以以纸质卷材收卷备用,仅在制作平面结构是,才需要放卷拉伸等操作,从而可以最大可能降低模切纸的物料储存成本。
另外,保护层采用衬垫,而衬垫是模切纸模切后拉伸形成,相对于填充粉末、颗粒等,对环境污染小,减小工作人员健康带来潜在伤害。
本发明同时提供了上述全回收环保包装结构的制作方法,该制作方法包括:
步骤S1:准备至少两卷纸质原纸卷;步骤S2:选取至少一卷原纸卷,放卷处理形成模切纸,并将模切纸收卷备用;步骤S3:选至少一卷原纸卷以及至少一卷模切纸卷材同向放卷,并对所述模切纸卷材拉伸形成衬垫带,将衬垫带与放卷的原材带贴合,从而形成平面结构带。
本发明公开的制作方法中衬垫以及原纸卷均采用纸质材料制成,回收时不需要分离,克服了现有技术中缓冲材料无法分离,无法回收污染环境的问题。同时,将衬垫作为缓冲克服了现有技术中采用粉末状、颗粒状的松软结构作为缓冲材料,所造成的环境污染,空气质量差的技术问题。同时采用衬垫作为缓冲材料,能够达到现有的塑料板、塑胶泡作为缓冲材料的缓冲效果,保证内部物品不损坏的目的。另外,采用本发明制作包装结构时,整个原材制作,包括衬垫带的制作均是在送卷的过程中实现,在拉伸、贴合、模切的过程中,传送带一直处于送给状态,生产的效率较高。

具体实施方式
下面结合具体实施例和说明书附图对本发明做进一步阐述和说明:
请参考图3,本发明公开一种全回收环保包装结构100,该全回收环保包装结构100应用于快递、邮政以及物流领域,由纸质的平面结构10构成,其中该平面结构10包括:第一面11以及保护层12,其中所述保护层12重叠于第一面11上,该保护层12起到减震保护的目的,所述第一面11起到了支撑保护层12的作用,由第一面11和所述保护层12共同作用形成的平面结构10可以包裹于物品,快递件的外部,能够防止快递以及邮政包裹的损坏。
参考图4,具体的,该保护层12包括一层衬垫13,所述衬垫13是纸质材质经模切纸14拉伸形成的网状结构。
在本实施方式中,模切纸14与第一面11采用的纸质材料相同,此时,在制造该包装结构100而备料时,更加方便快捷,第一面11的纸质材料和模切纸14的纸质材料可以混用,减小备料成本。当然,根据实际的需要以及所包裹的物品和快递件的特性,在其他实施方式中也可以采用不同的纸质材质,例如第一面11采用更为结实的牛皮纸,而模切纸14采用普通书写纸。
其中,所述模切纸14模切后会形成多排模切线141,每排模切线141包括模切后彼此间隔设置的多个模切刀线142。在同一张模切纸14上模切后会形成多排彼此平行的模切线141,每相邻的两个模切线141之间的间隔距离相同。这种等间距模切的方式,能够降低模切工艺难度,且成本也会降低。
如图5,模切刀线142是指通过模切刀模切后,在预设定的模切纸14的位置形成的压痕,或者将模切纸14分离开的刀口。模切刀线142位于模切线141上,间隔设置,即,模切刀线142和未模切部分间隔,穿插设置,在模切纸14上,形成类似断续线,模切刀线142为断续线中的断离部分。该模切刀线142经过拉伸后形成模切口143,模切口143就是断续部分的边缘向模切口143两侧移动后形成得,模切口143为菱形,在拉伸后的模切纸14形成了多排菱形开口排布的网状结构,该网状结构为松软组织结构,当重叠在第一面11上起到保护的作用。
如图6,在另外一种实施方式中,相邻两个模切线141的模切间距也可以不同,此时根据所要保护的强度情况区别对待,例如,当该平面结构10用于包裹玻璃等易碎品时,需要一圈圈的环绕在易碎品上,环绕易碎品的内层平面结构10中的模切线141间隔小于环绕在外层的平面结构10的模切线141的间隔,这样的话能够在不降低保护强度的前提条件下,尽可能的减小模切次数,降低成本。
如图7,在本发明的其他实施方式中,该模切线141为直线,在另外一种实施方式中,这些模切线141也可以是弧线。无论模切线141的形状,仅需要保证模切线之间彼此平行,在拉伸时,能够拉伸形成网状结构即可。
如图8,其中,在本发明的其他实施方式中,该保护层12还可以包括多层衬垫13,即两层以上的衬垫13,此时每层衬垫13都是由模切纸14拉伸形成 的松软的网状结构,多层衬垫13叠加后形成保护层12,保护作用相较于仅一层衬垫13进一步增强。
如图9及图10,在本实施方式中,多层衬垫13叠加后形成保护层12时,多层衬垫13具有多种叠加方式,例如:横竖叠加,即一层衬垫13的一列模切口143的排布方式与另一层衬垫13的模切口143的排布方式彼此之间垂直;交叉叠加,即一层衬垫13的一列模切口143的排布方式与另一层衬垫13的模切口143的排布方式彼此之间呈夹角设置;错位叠加,即一层衬垫13的一列模切口143排布的位置位于另一层衬垫13的相邻的两排模切口143之间的位置;总之,叠加后的多层所述衬垫13的模切口143位置不完全重合。不完全重合的多层衬垫13能够使得保护层12为更加松软的组织,进一步增强保护性能。
参阅图11,其中,在本发明的另一种实施方式中,该平面结构10包括第二面15,所述第二面15与所述第一面11之间夹持所述保护层12。
在本实施方式中,第一面11与第二面15材质相同所起到的作用也相同,将保护层12设置在第一面11与第二面15之间,能够防止松软的保护层12在使用的过程中与包裹的物品,快递件干涉,导致脱落;同时还能够增加平面结构10的结构强度,防止平面结构10的撕裂等问题的出现。
参阅图12及图13,其中,本发明的另一种包装结构100由上述的平面结构10折叠后封边形成,该包装结构100为的一种袋体。此时该平面结构10包括具有第一面11和保护层12的一种实施方式,同时也包括具有第一面11、保护层12以及第二面15的另一种实施方式。具体的,包装结构100在平面结构10折叠后,将垂直于折叠线的两侧边缘粘固,并在平行于折叠线另一端的位置上预留一个开口,至此包装袋的袋体已经形成,待包裹的物品或者邮政快递件通过该开口放入袋体中,该物品放入袋体中后,被保护层12包围,起到保护的作用。
如图14,在本发明的一种实施方式中,所述保护层12完全重叠于整个所述第一面11,或者第一面11和第二面15。如图12及图13,此时,经折叠,边缘粘固后的袋体的内壁均布置有保护层12,该袋体开口位置没有设置用于封 口的封盖。
如图15及图16,在本发明的另外一种实施方式中,所述保护层12并未完全重叠于整个所述第一面11,或者第一面11和第二面15,在第一面11,或第一面11和第二面15上预留有裸露区域101。此时,在折叠时,该裸露区域101位于所需要折叠的区域的外部,折叠后,该裸露区域101作为新形成的袋体的封盖,用于封闭所述袋体的开口。
本发明以上的实施方式中,第一面11和第二面15以及保护层12均为可回收的环保材料制成。
参阅图17及图19,本发明同时还提供了一种全回收环保包装结构100的制作方法,该制作方法包括:步骤S1:准备至少两卷纸质原纸卷。
在该步骤中,准备的原材包括至少两卷原纸卷,即准备的原材均是卷材。其中选用的原纸卷的材料可以相同,也可以根据不同的需要不完全相同。不过,所选用的原纸卷均应是可回收的环保材料,例如可回收、可降解的环保纸质材料。
步骤S2:选取一卷原纸卷,放卷处理后形成模切纸,并将模切纸收卷备用。
在本步骤中,从备料纸质原纸卷中选取一卷原纸卷,该被选取的原纸卷与所有的原纸卷纸质材质完全相同,所以随机选取即可,此时在制造该包装结构而备料时,更加方便快捷,所备的纸质原纸卷可以混用,减小备料成本。
当然,在本步骤中,根据实际的需要以及所包裹的物品和快递件的特性,也可以备不同的纸质材质的两种原纸卷,将两种原纸卷彼此区分,将普通的原纸卷与作为模切纸的特殊原纸卷区分。这样,在本步骤中选择原纸卷时也只能从做出标记的特殊原纸卷中选取。
本步骤S2具体的,还包括:
步骤S21:原纸卷放卷;在本步骤中,放卷采用转动辊放卷,此时放卷的原纸卷随转动辊的转动而放卷。
步骤S22:对原纸卷放卷部分模切,形成多排模切线,每排模切线包括模切后彼此间隔设置的多个模切刀线。
在本步骤中,用模切刀模切时,原纸卷步进放卷,每次放卷为至少一个模 切刀的长度,放卷后通过模切刀,对原纸卷切割;再次放卷后再次切割,直至纸质原纸卷全部放卷及切割完成形成模切纸,并对模切纸收卷备用。
其中模切后,多个模切线彼此之间平行设置,相邻两条模切线之间的间距相同。这种等间距模切的方式,能够降低模切工艺难度,且成本也会降低。
在另外一种实施方式中,相邻两个模切线的模切间距也可以不同,此时根据所要提供保护的强度情况区别对待,例如,当该平面结构用于包裹玻璃等易碎品时,需要一圈圈的环绕在易碎品上,环绕易碎品的内层平面结构中的模切线间隔小于环绕在外层的平面结构的模切线的间隔,这样的话能够在不降低保护强度的前提条件下,尽可能的减小模切次数,降低成本。
模切线是指通过模切刀或者用于模切的模切刀模切后,在预设定的模切纸的位置形成的压痕,或者将模切纸分离开的模切导线。模切刀线位于模切线上并间隔设置,即,模切刀线和未模切部分间隔,穿插设置,在模切纸上,形成类似断续线,模切刀线为断续线中的断离部分。
步骤S3:选一卷原纸卷以及一卷模切纸卷材同向放卷,并对所述模切纸卷材拉伸形成衬垫带,将衬垫带与放卷的原材带重叠,从而形成平面结构带。
具体的,该模切纸卷材拉伸时,首先模切纸卷放卷,放卷后在放卷端与远离放卷端的一侧的放卷速度不同,放卷端的放卷速度小于远离放卷端的一侧,此时,远离放卷一端对模切纸拉伸,此时,该模切刀线经过拉伸后形成模切口,模切口就是断续部分的边缘向模切口两侧移动后形成得,模切口为菱形,在拉伸后的模切纸形成了多排菱形开口排布的网状结构,该网状结构为松软组织结构,起到保护的作用,该网状结构就形成了衬垫带。
在本步骤中,在本步骤中衬垫带与放卷的原纸卷重叠,包括几种情形:
第一种,衬垫的边缘必然是锯齿状,无法保证和作为平面结构第一面和第二面的原材带的边缘完全平齐,不宜采用涂胶的方式。涂胶的方式难以保证所涂胶水的均匀。
在本步骤中,采用喷涂的方式涂覆胶水,将衬垫与卷带的两侧均匀喷上胶水,还需要说明的是,胶水为树脂胶水,压合时需要向原材带加热,以使所述树脂胶水达到粘固所需要的温度;在未热压合之前,树脂胶水不具有粘贴特性, 从而可以在产线工作,折叠之前就喷涂胶水,而不用担心胶水的后期粘贴使粘结特性的改变无法粘固。
在本实施方式中,采用喷涂树脂胶水的方式能够保证衬垫与卷带两侧胶水均匀,有利于提高固定强度。同时,加热压合的方式压紧卷带与衬垫有利于树脂胶水的固定,提高固定强度。
另一种,衬垫的任意位置间隔喷涂胶水,并不需要沿着边缘部分喷涂,仅需要保证衬垫和放原纸卷之间不脱落即可。采用这种任意喷涂胶水的方式,除过喷涂胶水的位置,其他衬垫都处于松软的状态,保护效果更强。
在本发明的其他实施方式中,所述步骤S3还可以是:选择一卷原纸卷以及至少两卷模切纸卷材,并对所有模切纸卷材拉伸形成多个衬垫带,将多个衬垫带与放卷的原纸卷重叠,从而形成平面结构带。
在本实施方式中,多卷模切纸卷放卷后均位于一卷原纸卷放卷后的同一侧,多个衬垫带彼此叠加一起,并一同重叠与原纸卷上。本实施方式增加了衬垫带的数量,在制作成平面结构后,具有更好的保护作用,同时在制作过程中,仅需要增加放卷的模切纸卷即可,成本低,效率高。
在本发明的其他实施方式中,所述步骤S3还可以是:选择两卷原纸卷以及至少一卷模切纸卷材,并对所有模切纸卷材拉伸形成多个衬垫带,多个衬垫带均位于两卷原纸卷放卷后的卷材之间,将多个衬垫带与两个原纸卷重叠,形成平面结构带。
在本步骤中,形成的平面结构带具有第一面以及第二面,夹持于第一面和第二面之间的至少一层衬垫的保护层,更加结实牢固,减震效果更好,增加另一层原纸卷的工艺成本较低。当然此时,第一面和第二面之间保护层也可以包括多层的衬垫。
参阅图18及图19,其中,本发明的制作方法还包括平面结构形成袋体的方法,即步骤S4:
步骤S4:沿垂直于平面结构带进给方向间隔施胶;沿进给方向折叠,使施胶位置相重合,对施胶位置压合,使胶水凝固;在施胶位置裁切,形成袋体。
在本步骤中,平面结构带一遍进给,同时对垂直进给方向间隔施胶,施胶 的位置在裁切后,就是折叠压合的位置,裁切后的平面结构两侧即是相邻的两施胶位置。折叠压合后,施胶位置粘固,此时袋体形成。
在本发明的一种实施方式中,衬垫带完全重叠于所述原纸卷带上,折叠时,折叠线位于衬垫带长度方向的中心线上,此时折叠后的袋体内壁上布满所述衬垫带,且该袋体在开口位置不设置用于封口的结构。
在本发明的另外一种实施方式中,所述衬垫带未完全重叠于所述原纸卷带上,在所述原纸卷带在沿长度延伸的边缘上预留有裸露区域101;所述平面结构带在折叠时沿所述衬垫带长度方向折叠;折叠后,所述裸露区域101用于封盖所述袋体的袋口。
其中,在所述封盖的内侧上涂覆封口胶,并用离型纸覆盖,在使用时,撕去离型纸就可以直接将封盖折叠封于所述袋体的袋口位置。
本发明公开的制作方法中保护层采用的衬垫带以及原纸卷均采用可回收环保材料制成,经衬垫作为缓冲的保护层,克服了现有技术中采用粉末状、颗粒状的松软结构作为缓冲材料,所造成的环境污染,空气质量差的技术问题,同时采用多层衬垫作为缓冲材料,能够达到现有的塑料板、塑胶泡作为缓冲材料的缓冲效果,保证内部物品不损坏的目的。另外,采用本发明制作包装结构时,整个原材制作,包括衬垫带的制作均是在传送带上实现,在多层重叠、折叠、粘固、模切的过程中,传送带一直处于送给状态,生产的效率较高。
最后应当说明的是,以上实施例仅用以说明本发明的技术方案,而非对本发明保护范围的限制,尽管参照较佳实施例对本发明作了详细地说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或者等同替换,而不脱离本发明技术方案的实质和范围。
