  我們都知道,不(bu)(bu)(bu)同(tong)結構、不(bu)(bu)(bu)同(tong)材質(zhi)的(de)(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang),其紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)價格也截然不(bu)(bu)(bu)同(tong),并且紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)價格與原紙(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)品(pin)(pin)種(zhong)、質(zhi)量等(deng)級關系較大。制(zhi)作(zuo)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)就是要(yao)根據(ju)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)的(de)(de)(de)(de)使用特點和(he)(he)(he)運輸條件確定(ding)用紙(zhi)(zhi)(zhi)(zhi)(zhi)品(pin)(pin)種(zhong)和(he)(he)(he)質(zhi)量,這是保持適度包裝,控制(zhi)生產成本所值得(de)重視的(de)(de)(de)(de)環節(jie)。制(zhi)作(zuo)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)的(de)(de)(de)(de)原紙(zhi)(zhi)(zhi)(zhi)(zhi)主要(yao)包括(kuo)白紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)、瓦(wa)楞(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)、茶(cha)板(ban)紙(zhi)(zhi)(zhi)(zhi)(zhi)、普通箱(xiang)紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)和(he)(he)(he)牛皮掛(gua)面箱(xiang)紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)等(deng),這些原紙(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)制(zhi)作(zuo)工(gong)藝和(he)(he)(he)材料上的(de)(de)(de)(de)不(bu)(bu)(bu)同(tong),標準也有(you)所差異。涂(tu)布(bu)白紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)有(you)白底和(he)(he)(he)灰(hui)底兩種(zhong),質(zhi)量等(deng)級也有(you)分(fen)優(you)等(deng)品(pin)(pin)、一等(deng)品(pin)(pin)和(he)(he)(he)合格品(pin)(pin)三種(zhong),檢(jian)測(ce)的(de)(de)(de)(de)項目有(you):水分(fen)、定(ding)量、定(ding)量偏差、橫幅定(ding)量差、緊度、亮度(白度)、印(yin)刷(shua)表面粗(cu)糙(cao)度、平滑度、印(yin)刷(shua)光(guang)澤(ze)度、油墨吸收性(xing)、印(yin)刷(shua)表面強度、吸水性(xing)、橫向挺度和(he)(he)(he)塵埃度等(deng)。白紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)是預印(yin)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)面紙(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)采用材料,白紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)的(de)(de)(de)(de)質(zhi)量對紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)的(de)(de)(de)(de)印(yin)刷(shua)和(he)(he)(he)強度都有(you)較大的(de)(de)(de)(de)影響。

  白(bai)紙(zhi)(zhi)板(ban)的(de)(de)水(shui)分、印(yin)刷(shua)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)粗(cu)糙度(du)(du)(du)(du)(du)、平滑(hua)度(du)(du)(du)(du)(du)和表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)強度(du)(du)(du)(du)(du)等,對(dui)印(yin)刷(shua)質量的(de)(de)影響(xiang)比較敏感,水(shui)分對(dui)印(yin)刷(shua)版面(mian)(mian)(mian)(mian)的(de)(de)套準(zhun)會(hui)有一(yi)(yi)定的(de)(de)影響(xiang),而印(yin)刷(shua)表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)粗(cu)糙度(du)(du)(du)(du)(du)、平滑(hua)度(du)(du)(du)(du)(du)和表(biao)(biao)(biao)面(mian)(mian)(mian)(mian)強度(du)(du)(du)(du)(du)指標對(dui)印(yin)刷(shua)質量影響(xiang)較大(da),如印(yin)刷(shua)油墨(mo)層(ceng)能否飽和、紙(zhi)(zhi)面(mian)(mian)(mian)(mian)印(yin)刷(shua)后能否出現脫層(ceng)和起泡問(wen)題。白(bai)紙(zhi)(zhi)板(ban)的(de)(de)橫向挺度(du)(du)(du)(du)(du)則影響(xiang)到紙(zhi)(zhi)箱(xiang)的(de)(de)抗壓強度(du)(du)(du)(du)(du);白(bai)紙(zhi)(zhi)板(ban)的(de)(de)緊度(du)(du)(du)(du)(du)不是越(yue)(yue)高(gao)(gao)越(yue)(yue)好,而是規定不大(da)于一(yi)(yi)個標準(zhun)值,如優等品(定量≤300克)不大(da)于0.88g/cm3。因為如果(guo)白(bai)紙(zhi)(zhi)板(ban)的(de)(de)緊度(du)(du)(du)(du)(du)過高(gao)(gao),紙(zhi)(zhi)箱(xiang)搖(yao)蓋的(de)(de)耐(nai)折度(du)(du)(du)(du)(du)就會(hui)明(ming)顯下(xia)降,使用過程中搖(yao)蓋就容易出現斷裂現象(xiang)。

  瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)多用于紙(zhi)(zhi)箱(xiang)的(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)層(ceng),也(ye)有(you)用于瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)板(ban)夾芯層(ceng)或(huo)里(li)層(ceng)。用于瓦(wa)(wa)(wa)楞(leng)(leng)(leng)層(ceng)的(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi),它的(de)質(zhi)(zhi)量(liang)(liang)(liang)如(ru)何直接影(ying)(ying)響(xiang)到(dao)紙(zhi)(zhi)箱(xiang)的(de)抗(kang)壓(ya)(ya)(ya)強度(du)(du)(du)。瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)的(de)標準分(fen)A、B、C和(he)D四個等(deng)級,A等(deng)質(zhi)(zhi)量(liang)(liang)(liang)指(zhi)(zhi)標最高,其常規(gui)檢驗的(de)項(xiang)目有(you)水(shui)分(fen)、定(ding)(ding)量(liang)(liang)(liang)、緊(jin)度(du)(du)(du)、橫(heng)(heng)(heng)向(xiang)環壓(ya)(ya)(ya)指(zhi)(zhi)數和(he)裂斷長等(deng),其中橫(heng)(heng)(heng)向(xiang)環壓(ya)(ya)(ya)指(zhi)(zhi)數、定(ding)(ding)量(liang)(liang)(liang)和(he)緊(jin)度(du)(du)(du)指(zhi)(zhi)標,對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)板(ban)的(de)邊(bian)壓(ya)(ya)(ya)強度(du)(du)(du)影(ying)(ying)響(xiang)較大。箱(xiang)板(ban)紙(zhi)(zhi)一(yi)般用于紙(zhi)(zhi)箱(xiang)面(mian)紙(zhi)(zhi)或(huo)里(li)紙(zhi)(zhi),其質(zhi)(zhi)量(liang)(liang)(liang)對紙(zhi)(zhi)箱(xiang)的(de)強度(du)(du)(du)影(ying)(ying)響(xiang)較大。普(pu)通箱(xiang)板(ban)紙(zhi)(zhi)和(he)牛皮掛面(mian)箱(xiang)紙(zhi)(zhi)板(ban)分(fen)為(wei)(wei)優(you)等(deng)品、一(yi)等(deng)品和(he)合格品三種。它們的(de)標準有(you)水(shui)分(fen)、定(ding)(ding)量(liang)(liang)(liang)、緊(jin)度(du)(du)(du)、橫(heng)(heng)(heng)向(xiang)環壓(ya)(ya)(ya)指(zhi)(zhi)數、耐破指(zhi)(zhi)數、正反面(mian)吸水(shui)性(xing)、橫(heng)(heng)(heng)向(xiang)耐折度(du)(du)(du)等(deng),其中橫(heng)(heng)(heng)向(xiang)環壓(ya)(ya)(ya)指(zhi)(zhi)數、耐破指(zhi)(zhi)數和(he)定(ding)(ding)量(liang)(liang)(liang)對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)板(ban)的(de)耐破度(du)(du)(du)、戳(chuo)穿強度(du)(du)(du)和(he)邊(bian)壓(ya)(ya)(ya)強度(du)(du)(du)影(ying)(ying)響(xiang)明顯,這些(xie)都是為(wei)(wei)生產工藝實(shi)踐所(suo)證明的(de)客觀事實(shi)。

  因此,原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)作為(wei)(wei)紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)質量(liang)(liang)(liang)的(de)(de)(de)(de)(de)源頭環節,必須注重進行嚴密、有(you)效的(de)(de)(de)(de)(de)控制。主要做法有(you):采(cai)購(gou)(gou)時(shi)在(zai)合(he)同(tong)中要明確原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)采(cai)購(gou)(gou)的(de)(de)(de)(de)(de)品種(zhong)、質量(liang)(liang)(liang)等(deng)級(ji)和標(biao)(biao)準(zhun)(zhun)項(xiang)目(mu)的(de)(de)(de)(de)(de)要求,檢驗項(xiang)目(mu)、標(biao)(biao)準(zhun)(zhun)值可(ke)(ke)以(yi)參照相關(guan)的(de)(de)(de)(de)(de)國(guo)標(biao)(biao),也(ye)可(ke)(ke)以(yi)由供(gong)需雙方約(yue)定。應(ying)根據產品的(de)(de)(de)(de)(de)特點(dian)確定原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)標(biao)(biao)準(zhun)(zhun)和檢驗項(xiang)目(mu),如(ru)可(ke)(ke)對(dui)瓦楞紙(zhi)(zhi)(zhi)(zhi)(zhi)、箱(xiang)板(ban)紙(zhi)(zhi)(zhi)(zhi)(zhi)增加(jia)施膠(jiao)度(du)的(de)(de)(de)(de)(de)檢測項(xiang)目(mu),因為(wei)(wei)原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)表(biao)面如(ru)果施膠(jiao)度(du)好(hao),原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)就不易(yi)吸濕(shi),裱貼時(shi)粘合(he)劑吸收量(liang)(liang)(liang)相應(ying)也(ye)少(shao),有(you)利于紙(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)的(de)(de)(de)(de)(de)干燥和提高紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)強度(du)。此外,就是(shi)要對(dui)采(cai)購(gou)(gou)的(de)(de)(de)(de)(de)原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)進行驗收,按(an)(an)標(biao)(biao)準(zhun)(zhun)、按(an)(an)合(he)同(tong)規定的(de)(de)(de)(de)(de)規則進行檢驗,這是(shi)保證采(cai)購(gou)(gou)質量(liang)(liang)(liang)的(de)(de)(de)(de)(de)重要一環。因為(wei)(wei)買(mai)原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)不是(shi)簡單的(de)(de)(de)(de)(de)買(mai)品種(zhong)、買(mai)數量(liang)(liang)(liang),而是(shi)買(mai)原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)標(biao)(biao)準(zhun)(zhun)和質量(liang)(liang)(liang),可(ke)(ke)以(yi)說,買(mai)合(he)格(ge)的(de)(de)(de)(de)(de)原(yuan)紙(zhi)(zhi)(zhi)(zhi)(zhi),是(shi)降(jiang)低(di)生產成本(ben),提高紙(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)質量(liang)(liang)(liang)的(de)(de)(de)(de)(de)基礎。
