在當今競爭激烈的重型瓦楞紙箱包裝市場中，從重瓦楞紙箱的出現到成為重包裝市場中不可或缺的包裝。越來越多的人知道重紙箱行業可以受到青睞，重紙箱工廠遍地都是，重紙箱多樣化。在與重型紙箱廠合作之前，除了對重型紙箱廠的檢驗外，對重型瓦楞紙箱的質量檢驗也是重中之重。很多紙箱生產、批發企業，為了獲取利潤出現偷工減料，所以造成了紙箱的一系列坍塌、斷裂、變形、軟化等現象。為了避免為劣質產品付出高昂的代價，
瓦楞紙箱廠家小編告訴大家，外觀厚重的瓦楞紙箱和內部質量檢測，不容忽視。
In today's highly competitive heavy-duty corrugated box packaging market, from the emergence of heavy corrugated box to become an indispensable packaging market. More and more people know that heavy carton industry can be favored, heavy carton factories are everywhere, heavy carton diversification. Before cooperating with the heavy-duty carton factory, in addition to the inspection of the heavy-duty carton factory, the quality inspection of the heavy-duty corrugated carton is also the top priority. Many carton production and wholesale enterprises, in order to obtain profits, have been cutting corners, which has resulted in a series of collapse, fracture, deformation, softening and other phenomena of cartons. In order to avoid paying a high price for inferior products, the small series of corrugated box manufacturers told us that the corrugated box with heavy appearance and internal quality inspection should not be ignored.
合格的重型紙箱，在外觀要求方面，是印刷文字和文字清晰準確，色彩飽和度一致，無斷線和遺漏，易掉線。印刷位置誤差一般控制在4mm-7mm。重型瓦楞紙箱表面光滑，無凹痕問題，對角線整齊，無破損，污漬少，箱體周圍間隙不大，無孔，箱體尺寸誤差應在3mm-5mm之內。含水率，瓦楞紙板或紙箱含水率過高或過低，都會影響紙箱的壓縮、耐磨性、抗穿刺、折疊性能。簡單地說，如果含水量過高，盒子就會軟化;如果含水量過低，盒子就會破裂。小編教你一種測試含水率的技巧，剪下一小塊紙板或紙箱的不同部位，烘干恒重。用(樣品原重量-烘干后重量)/原重量*100%=紙板/紙箱含水率。
The qualified heavy-duty cartons, in terms of appearance requirements, are printed with clear and accurate text, consistent color saturation, no broken lines and omissions, easy to drop lines. The printing position error is generally controlled at 4mm-7mm. The surface of heavy-duty corrugated box is smooth and free of dents. The diagonal is neat and free of damage. There is little stain. The gap around the box is not big and there is no hole. The size error of the box should be within 3mm-5mm. Moisture content, corrugated board or carton moisture content is too high or too low, will affect the compression, wear resistance, puncture resistance, folding performance of the carton. Simply put, if the water content is too high, the box will soften; if the water content is too low, the box will break. The editor teaches you a technique to test the moisture content. Cut out different parts of a small piece of cardboard or carton and dry it to constant weight. Use (original weight of sample - weight after drying) / original weight * 100% = moisture content of cardboard / carton.
