定做紙箱在選擇瓦楞原紙和箱紙板時(shí)，其選配應(yīng)以下兩個(gè)原則。
When selecting corrugated base paper and carton board for custom-made cartons, the selection and matching shall comply with the following two principles.
1質(zhì)量選配原則
(1) quality selection principle
一般應(yīng)盡量選用質(zhì)量等級(jí)接近的瓦楞原紙和箱紙板來(lái)生產(chǎn)瓦楞紙板。如高等級(jí)箱紙板應(yīng)盡量選用A級(jí)瓦楞原紙;較等級(jí)箱紙板則可選用C、D級(jí)瓦楞原紙。如果選用高等級(jí)的箱板紙與等級(jí)的瓦楞原紙，制成的瓦楞紙板平壓強(qiáng)度，非常容易塌楞，箱紙板的優(yōu)良性能無(wú)法體現(xiàn)。
Generally, corrugated base paper and carton board with similar quality grade shall be selected as far as possible to produce corrugated board. For example, grade a corrugated base paper shall be selected as far as possible for high-grade carton board; For lower grade carton board, grade C and D corrugated base paper can be selected. If high-grade box board paper and low-grade corrugated base paper are selected, the corrugated board produced has low flat pressing strength and is very easy to collapse, and the excellent performance of box board cannot be reflected.
2定量選配原則
(2) quantitative matching principle
如果瓦楞原紙定量過(guò)高，而箱紙板定量不能與其相匹配，則會(huì)使瓦楞紙板表面不平整，產(chǎn)生明顯的瓦楞條紋，影響外觀質(zhì)量和印刷效果;如果瓦楞原紙定量過(guò)，而箱紙板定量過(guò)高，二者貼合后會(huì)使瓦楞的齒形變形，影響瓦楞紙板的厚度、邊壓強(qiáng)度及緩沖性能。箱紙板與瓦楞原紙的定量之比一般維持在2∶1比較好。
If the quantity of corrugated base paper is too high and the quantity of carton board cannot match it, the surface of corrugated board will be uneven and obvious corrugated stripes will be produced, which will affect the appearance quality and printing effect; If the weight of the corrugated base paper is too low and the weight of the box board is too high, the tooth shape of the corrugated will be deformed after the two are bonded, and the thickness, edge pressure strength and cushioning performance of the corrugated board will be affected. The ration ratio of carton board to corrugated base paper is generally maintained at 2:1.
