为什么黄牛皮纸袋更容易出现色差?
在包装行业中,黄牛皮纸(zhi)袋以其(qi)天然、环(huan)保、耐用等特点备受青睐。然而,色差(cha)问题却常(chang)常(chang)困扰着生产厂家和客户。色差(cha)不(bu)仅影响黄牛皮纸(zhi)袋的(de)外(wai)观(guan)质量,还(hai)可能对琐谓品牌形象产生负面影响。今(jin)天咱们来聊(liao)聊(liao)黄牛皮纸(zhi)袋那些让人(ren)有点小烦恼的(de)色差(cha)问题。
一、黄(huang)牛(niu)皮纸(zhi)袋色差产生的(de)原因(yin)
1.牛皮纸原材料
不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)厂(chang)家(jia)原料(liao)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)差异(yi)显著(zhu)。不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)厂(chang)家(jia)在(zai)选择木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)来源(yuan)时各不(bu)(bu)(bu)相(xiang)同(tong)(tong)(tong)(tong),有的(de)(de)(de)采(cai)用进口木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang),有的(de)(de)(de)则选用国产(chan)(chan)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)。不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)产(chan)(chan)地(di)的(de)(de)(de)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)在(zai)纤维(wei)特(te)性和(he)颜(yan)(yan)(yan)色(se)(se)上(shang)存(cun)在(zai)一(yi)(yi)(yi)(yi)定差异(yi)。例如,进口木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)可(ke)(ke)能较(jiao)为均匀,而(er)(er)国产(chan)(chan)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)可(ke)(ke)能会(hui)有细微变(bian)化(hua)。此外(wai),不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)厂(chang)家(jia)对(dui)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)的(de)(de)(de)处理(li)工(gong)艺也有所不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)。一(yi)(yi)(yi)(yi)些(xie)厂(chang)家(jia)在(zai)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)的(de)(de)(de)漂白(bai)、净化(hua)等(deng)环节(jie)采(cai)用先进技(ji)术,使木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)更(geng)加纯净一(yi)(yi)(yi)(yi)致;而(er)(er)另(ling)一(yi)(yi)(yi)(yi)些(xie)厂(chang)家(jia)的(de)(de)(de)处理(li)相(xiang)对(dui)简单,导(dao)致木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)存(cun)在(zai)波动(dong)。同(tong)(tong)(tong)(tong)一(yi)(yi)(yi)(yi)厂(chang)家(jia)不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)批次原料(liao)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)也不(bu)(bu)(bu)完全一(yi)(yi)(yi)(yi)致。季(ji)节(jie)对(dui)木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)有影(ying)响,喷鸽夏季(ji)树木(mu)(mu)(mu)(mu)(mu)(mu)生(sheng)长旺盛,木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)可(ke)(ke)能相(xiang)对(dui)较(jiao)浅(qian);冬季(ji)树木(mu)(mu)(mu)(mu)(mu)(mu)生(sheng)长缓慢(man),木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)稍深。温(wen)度和(he)湿(shi)度也会(hui)影(ying)响木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se),高(gao)温(wen)高(gao)湿(shi)环境(jing)可(ke)(ke)能使木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)变(bian)深,低温(wen)干燥环境(jing)则可(ke)(ke)能使木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)颜(yan)(yan)(yan)色(se)(se)变(bian)浅(qian)。同(tong)(tong)(tong)(tong)时,原料(liao)配比(bi)的(de)(de)(de)调整也会(hui)导(dao)致颜(yan)(yan)(yan)色(se)(se)变(bian)化(hua)。即使是(shi)同(tong)(tong)(tong)(tong)一(yi)(yi)(yi)(yi)厂(chang)家(jia),在(zai)不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)批次的(de)(de)(de)生(sheng)产(chan)(chan)中,为控(kong)制成本或满足(zu)不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)客户需求,可(ke)(ke)能会(hui)调整不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)种类木(mu)(mu)(mu)(mu)(mu)(mu)浆(jiang)的(de)(de)(de)比(bi)例,从而(er)(er)引起颜(yan)(yan)(yan)色(se)(se)变(bian)化(hua)。2.生(sheng)产(chan)(chan)过(guo)程方面
不(bu)同(tong)厂(chang)家设备(bei)不(bu)同(tong),对(dui)色(se)差影响较(jiao)大。造纸(zhi)(zhi)设备(bei)的(de)先进程(cheng)度(du)和性能(neng)差异会反映在(zai)(zai)牛皮纸(zhi)(zhi)的(de)颜(yan)(yan)(yan)色(se)上(shang)。先进设备(bei)能(neng)够更(geng)地控(kong)制(zhi)生(sheng)产(chan)过程(cheng)中的(de)各项参数,如(ru)温度(du)压力(li)、车速等,从而(er)生(sheng)产(chan)出颜(yan)(yan)(yan)色(se)更(geng)加稳定一致的(de)牛皮纸(zhi)(zhi)。而(er)老(lao)旧设备(bei)在(zai)(zai)参数控(kong)制(zhi)上(shang)不(bu)够精准,容易导致不(bu)同(tong)批,次产(chan)品颜(yan)(yan)(yan)色(se)存在(zai)(zai)差异。此外,不(bu)同(tong)厂(chang)家的(de)设备(bei)在(zai)(zai)涂(tu)布、染色(se)等环(huan)节的(de)工艺(yi),也(ye)可(ke)能(neng)不(bu)同(tong)。例如(ru),有的(de)厂(chang)家采用的(de)涂(tu)布技术能(neng)使颜(yan)(yan)(去柿yan)色(se)更(geng)均匀地分布在(zai)(zai)纸(zhi)(zhi)张表(biao)面,而(er)有的(de)厂(chang)家的(de)涂(tu)布效果相对(dui)较(jiao)差,导致颜(yan)(yan)(yan)色(se)不(bu)均匀。3.生(sheng)产(chan)厂(chang)家
不(bu)同厂家生(sheng)产工(gong)(gong)艺(yi)不(bu)同也是色(se)差产生(sheng)的重要原因(yin)。制(zhi)(zhi)浆(jiang)工(gong)(gong)艺(yi)差异明显,化(hua)学制(zhi)(zhi)浆(jiang)、机械制(zhi)(zhi)浆(jiang)、半(ban)化(hua)学制(zhi)(zhi)浆(jiang)等不(bu)同的制(zhi)(zhi)浆(jiang)方法(fa)会影响(xiang)木浆(jiang)的纤维(wei)结构和(he)颜(yan)色(se)。化(hua)学制(zhi)(zhi)浆(jiang)可(ke)(ke)(ke)能(neng)(neng)使木浆(jiang)颜(yan吨苫)色(se)更(geng)加洁白,但会降低纤维(wei)强(qiang)度(du)(du);机械制(zhi)(zhi)浆(jiang)可(ke)(ke)(ke)能(neng)(neng)保留更梆奈(geng)多木纤维(wei)原色(se),但纤维(wei)长度(du)(du)和(he)强(qiang)度(du)(du)可(ke)(ke)(ke)能(neng)(neng)不(bu)同。干(gan)燥工(gong)(gong)艺(yi)差异也会影响(xiang)颜(yan)色(se),干(gan)燥温度(du)(du)过高或(huo)时间过长可(ke)(ke)(ke)能(neng)(neng)使纸(zhi)张颜(yan)色(se)变黄,而干(gan)燥不(bu)充分则可(ke)(ke)(ke)能(neng)(neng)导致纸(zhi)张颜(yan)色(se)不(bu)均。
二、避免色差的建议
1.选择可(ke)靠的(de)供应商
应(ying)(ying)尽(jin)量选择信誉良好、生产工艺先(xian)进(jin)、质(zhi)量稳定的(de)牛皮(pi)纸供应(ying)(ying)商。可以通过查看供应(ying)(ying)商的(de)资质(zhi)证书、客户评(ping)价、生产设备等方面来(lai)评(ping)估其可靠(kao)性(xing)。与供应(yi醒擦ng)(ying)商建(jian)立长期(qi)稳定的(de)合作关(guan)系,这样供应(ying)(ying)商能更(geng)好地了(le)解客户需求,在生产过程(cheng)中更(geng)加注重(zhong)颜色的(de)稳定性(xing)。2.明确颜色标准
在采购牛皮纸时,要(yao)(yao)(yao)明确规定颜(yan)(yan)色标(biao)准(zhun)。可(ke)以(yi)提供色卡或(huo)样品给供应商,要(yao饮茬)(yao)(yao)求其(qi)按照(zhao)指定的颜(yan)(yan)色进(jin)行(xing)生产(chan)。同时,明确允许的颜(yan)(yan)色偏差范(fan)围,以(yi)便(bian)在验收时进(jin)行(xing)检测(ce)。对于对颜(yan)(yan)色要(yao)(yao)(ya鹊奖o)求非常严格的客户,可(ke)以(yi)考虑使(shi)用专业的色差仪进(jin)行(xing)颜(yan)(yan)色检测(ce),确保颜(yan)(yan)色符合要(yao)(yao)(yao)求。
3.加(jia)强质(zhi)量(liang)控(kong)制(zhi)在生产黄牛皮菠渴(pi)纸(zhi)袋(dai)之(zhi)前,对采购的牛皮(pi)纸(zhi)进行抽样检测,检查颜色是否符合要求。若发现(xian)(xian)颜色偏差(cha)较大,及时与供(gong)应商沟通协(xie)商解决(jue)办(ban)法。在生产过程拖馍中,加(jia)强对各个环节的质(zhi)量(liang)控(kong)制(zhi),如印刷、涂(tu)布(bu)、贴合等,确保(bao)每一个环节的颜色都能(neng)保(bao)持稳定(ding)一致。建(jian)立完善的质(zhi)量(liang)追溯体系,一旦出现(xian)(xian)色差(cha)问题,可及时追溯到(dao)具体
的生(sheng)产环节(jie)和(he)原材料沥潭批次,以便(bian)采取有效的措施进(jin)(jin)行(xing)改淹莺进(jin)(jin)
4.合(he)理安(an)排(pai)生产计(ji)划
尽(jin)量避(bi)免频繁(fan闲徐)更(geng)换牛皮纸供应(ying)商或不同批次(ci)的原材(cai)料。若必(bi)须更(g卷胯eng)换,提前(qian)进(jin)行(xing)小样测试,确(que)保颜色符合要(yao)求后再进(jin)行(xing)大规模(mo)生(sheng)产。根(gen)据订单(dan)量和生(sheng)产周期,合理安排(pai)原材(cai)料的采购和库(ku)存管理,避(bi)免因库(ku)存积压时间过长导致(zhi)原材(cai)料颜色发(fa)生(sheng)变化(hua)。
总之,黄(huang)牛(niu)皮纸袋的(de)色(se)差问题是由(you)多种因素共同作用的(de)结果。通过(guo)对原(yuan)材料和生产过(guo)程的(de)严格(ge)控制,选择可靠的(de)供应商,明确(que)颜色(se)标准,加强质量控制以及合理安排生产计划等措施,尽量减(jian)少庄幸黄(huang)牛(niu)皮纸袋的(de)色(se)差问题,让咱们(men)的(de)包装既漂(piao)亮又稳(wen)定。快(kuai)来试试这(zhei)些(xie)方法吧!
