包裝紙箱廠家是怎么分類標準?

包裝紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)廠(chang)家(jia)按紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)質不(bu)同(tong),有(you)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)、單層紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)箱(xiang)(xiang)(xiang)等(deng)。紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)常用的(de)(de)(de)有(you)三層、五層,七層使(shi)用較(jiao)少,各層分(fen)為里(li)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、芯(xin)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)有(you)茶板(ban)(ban)(ban)(ban)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、牛皮紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),芯(xin)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)用瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),各種紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)顏色和手感(gan)都不(bu)一(yi)(yi)樣,不(bu)同(tong)廠(chang)家(jia)生產(chan)的(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(顏色、手感(gan))也不(bu)一(yi)(yi)樣。不(bu)同(tong)波紋形狀(zhuang)的(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng),粘結成的(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)功能(neng)也有(you)所不(bu)同(tong)。即(ji)使(shi)使(shi)用同(tong)樣質量(liang)的(de)(de)(de)面(mian)(mian)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)和里(li)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi),由于楞(leng)(leng)(leng)(leng)(leng)形的(de)(de)(de)差異,構成的(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)性能(neng)也有(you)一(yi)(yi)定(ding)區(qu)別。它們的(de)(de)(de)技術指標和要求見表一(yi)(yi)。A型楞(leng)(leng)(leng)(leng)(leng)制成的(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)具有(you)較(jiao)好的(de)(de)(de)緩沖性,富有(you)一(yi)(yi)定(ding)的(de)(de)(de)彈性,C型楞(leng)(leng)(leng)(leng)(leng)較(jiao)A型楞(leng)(leng)(leng)(leng)(leng)次之。但(dan)挺度(du)和抗沖擊性優(you)于A型楞(leng)(leng)(leng)(leng)(leng);B型楞(leng)(leng)(leng)(leng)(leng)排列密度(du)大,制成的(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)表面(mian)(mian)平整,承壓力高,適(shi)于印刷;E型楞(leng)(leng)(leng)(leng)(leng)由于薄而密,更呈(cheng)現(xian)了它的(de)(de)(de)剛強度(du)。包裝紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)廠(chang)家(jia)在生產(chan)和制造瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)時(shi),一(yi)(yi)般按紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)箱(xiang)(xiang)(xiang)的(de)(de)(de)箱(xiang)(xiang)(xiang)型來(lai)進(jin)行(xing)區(qu)分(fen)。

包裝紙箱廠(chang)家的箱型結構,在國際(ji)(ji)上普(pu)遍(bian)采用由歐洲(zhou)瓦楞紙箱制(zhi)造(zao)商聯(lian)合會(hui)(FEFCO)和瑞(rui)士紙板協會(hui)(ASSCO)聯(lian)合制(zhi)定的國際(ji)(ji)紙箱箱型標準(zhun)。這一標準(zhun)經國際(ji)(ji)瓦楞紙板協會(hui)批準(zhun)在國際(ji)(ji)間通(tong)用。按照國際(ji)(ji)紙箱箱型標準(zhun),紙箱結構可分為基(ji)礎型和組(zu)合型兩(liang)大類(lei)。
