瓦楞(leng)紙箱(xiang)(xiang)是一種應用廣泛的(de)包裝制品(pin)，用量多。其優(you)越的(de)使(shi)用性能(neng)和良好(hao)的(de)加工性能(neng)逐漸取代了(le)木箱(xiang)(xiang)等(deng)運輸(shu)包裝容器，成為運輸(shu)包裝的(de)主力軍。它除(chu)了(le)保護商(shang)品(pin)、便于倉儲(chu)、運輸(shu)之外(wai)，還起(qi)到美(mei)化(hua)商(shang)品(pin)，宣傳商(shang)品(pin)的(de)作用。瓦楞(leng)紙箱(xiang)(xiang)的(de)強(qiang)度也受到很多因素的(de)影響(xiang)，下面小(xiao)編給(gei)大(da)家介紹下。

1、箱(xiang)(xiang)體形(xing)(xing)狀。瓦楞紙箱(xiang)(xiang)的形(xing)(xing)狀不同(tong)，其抗壓(ya)強(qiang)度也截然(ran)不同(tong)。紙箱(xiang)(xiang)的支撐力大的是：箱(xiang)(xiang)體中(zhong)四個邊(bian)角和(he)緊鄰邊(bian)角的側邊(bian)，也就(jiu)是正(zheng)方形(xing)(xing)紙箱(xiang)(xiang)的支撐力相對就(jiu)比較大一些。此外，箱(xiang)(xiang)體周長越(yue)長，高度越(yue)高，其抗壓(ya)強(qiang)度相應就(jiu)越(yue)低;開(kai)孔(kong)面積越(yue)大，且越(yue)靠近邊(bian)角的，箱(xiang)(xiang)體的抗壓(ya)性能就(jiu)越(yue)下降。

2.瓦(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)箱(xiang)的(de)(de)波(bo)形(xing)(xing)(xing)(xing)。瓦(wa)楞(leng)(leng)(leng)的(de)(de)波(bo)形(xing)(xing)(xing)(xing)是指瓦(wa)楞(leng)(leng)(leng)上(shang)下兩(liang)個(ge)頂端(duan)及其相連線(xian)的(de)(de)形(xing)(xing)(xing)(xing)狀。瓦(wa)楞(leng)(leng)(leng)的(de)(de)波(bo)形(xing)(xing)(xing)(xing)有U形(xing)(xing)(xing)(xing)、V形(xing)(xing)(xing)(xing)和(he)UV形(xing)(xing)(xing)(xing)三種。U形(xing)(xing)(xing)(xing)楞(leng)(leng)(leng)呈圓弧形(xing)(xing)(xing)(xing)狀，這種瓦(wa)楞(leng)(leng)(leng)紙(zhi)(zhi)板(ban)(ban)緩沖性(xing)、彈性(xing)好，瓦(wa)楞(leng)(leng)(leng)輕微的(de)(de)變形(xing)(xing)(xing)(xing)可迅速復原，楞(leng)(leng)(leng)頂不(bu)易斷裂。但其所承受的(de)(de)壓(ya)力(li)，比V形(xing)(xing)(xing)(xing)楞(leng)(leng)(leng)的(de)(de)紙(zhi)(zhi)板(ban)(ban)差，且芯紙(zhi)(zhi)和(he)粘(zhan)合(he)劑(ji)的(de)(de)用量(liang)較(jiao)多(duo)。V形(xing)(xing)(xing)(xing)楞(leng)(leng)(leng)呈三角形(xing)(xing)(xing)(xing)狀，楞(leng)(leng)(leng)形(xing)(xing)(xing)(xing)由直線(xian)組(zu)成，V形(xing)(xing)(xing)(xing)楞(leng)(leng)(leng)紙(zhi)(zhi)箱(xiang)具有芯紙(zhi)(zhi)和(he)粘(zhan)合(he)劑(ji)的(de)(de)用量(liang)少，且有堅固(gu)耐用的(de)(de)良(liang)好特性(xing)，它的(de)(de)平(ping)面(mian)耐壓(ya)強度明顯高于U形(xing)(xing)(xing)(xing)楞(leng)(leng)(leng)的(de)(de)紙(zhi)(zhi)箱(xiang)，但是它的(de)(de)楞(leng)(leng)(leng)形(xing)(xing)(xing)(xing)一旦受壓(ya)變形(xing)(xing)(xing)(xing)，就難以恢復原狀。

3.瓦楞(leng)(leng)(leng)紙(zhi)(zhi)(zhi)箱(xiang)的(de)(de)類型(xing)(xing)。UV形瓦楞(leng)(leng)(leng)紙(zhi)(zhi)(zhi)板分(fen)為A、C、B和(he)(he)E型(xing)(xing)四種。A楞(leng)(leng)(leng)型(xing)(xing)的(de)(de)瓦楞(leng)(leng)(leng)高(gao)而寬，故(gu)(gu)有大楞(leng)(leng)(leng)型(xing)(xing)之稱。A楞(leng)(leng)(leng)型(xing)(xing)的(de)(de)紙(zhi)(zhi)(zhi)箱(xiang)承受平面壓(ya)力性(xing)(xing)能比B和(he)(he)C楞(leng)(leng)(leng)型(xing)(xing)差，但其承受垂直(zhi)壓(ya)力性(xing)(xing)能較(jiao)高(gao)，較(jiao)適(shi)合于(yu)(yu)制作盛裝(zhuang)不耐壓(ya)物品的(de)(de)紙(zhi)(zhi)(zhi)箱(xiang)。C楞(leng)(leng)(leng)型(xing)(xing)紙(zhi)(zhi)(zhi)箱(xiang)的(de)(de)楞(leng)(leng)(leng)高(gao)和(he)(he)單位長度(du)內的(de)(de)楞(leng)(leng)(leng)數，以及(ji)它(ta)的(de)(de)性(xing)(xing)能，介于(yu)(yu)A和(he)(he)B楞(leng)(leng)(leng)型(xing)(xing)之間，其又(you)(you)有細楞(leng)(leng)(leng)型(xing)(xing)之稱，適(shi)用于(yu)(yu)盛裝(zhuang)一般(ban)物品。B楞(leng)(leng)(leng)型(xing)(xing)的(de)(de)瓦楞(leng)(leng)(leng)低又(you)(you)密，故(gu)(gu)耐垂直(zhi)壓(ya)力性(xing)(xing)能較(jiao)差，但平面耐壓(ya)性(xing)(xing)能較(jiao)高(gao)，所以，用B楞(leng)(leng)(leng)型(xing)(xing)紙(zhi)(zhi)(zhi)板制作的(de)(de)紙(zhi)(zhi)(zhi)箱(xiang)，適(shi)用于(yu)(yu)盛裝(zhuang)瓶裝(zhuang)類的(de)(de)食品等。E楞(leng)(leng)(leng)型(xing)(xing)紙(zhi)(zhi)(zhi)板瓦楞(leng)(leng)(leng)低矮(ai)而又(you)(you)細密，故(gu)(gu)又(you)(you)稱為微型(xing)(xing)楞(leng)(leng)(leng)。E楞(leng)(leng)(leng)型(xing)(xing)的(de)(de)紙(zhi)(zhi)(zhi)板具有重量輕、緩沖性(xing)(xing)能好、平面抗壓(ya)強度(du)好等特點(dian)，利于(yu)(yu)于(yu)(yu)直(zhi)接進(jin)行印刷(shua)。
