纸箱检验作业指导书

一、主题内容与适用范围

1.1本标准规定了商品运输包装瓦楞纸箱的检验项目、检验方法、抽样数量及判定标准。

1.2本标准适用海运、陆运、空运等包装用单、双瓦楞的检验。

二、检验项目及方法

2.1外观检验之轻缺点项目

2.1.1印刷:箱面图案、文字正确,颜色深浅一致,位置准确。

2.1.2箱钉:不可有锈斑、剥层、龟裂,间距需均匀,单钉距≤55mm,钉距≤75mm,钉应钉牢、钉透。

2.1.3刀口:无明显毛刺,切口里面纸裂损距边≤8mm,长≤12mm,成箱的后叠角漏¢≤10mm

2.1.4结合

2.1.4.1钉合搭接舌宽为35-40mm,箱钉应沿搭接舌中线钉合,排列整齐,偏任斜不超过5mm

2.1.4.2纸箱两片接头应对齐,其剪刀差≤4mm,箱体方正。

2.2外观检验之重缺点

2.2.1内尺寸

2.2.1.1长、宽、高单项极限偏差为+3-2cm

2.2.1.2测量尺寸方法:纸箱支撑成型,相邻夹角成90度,用内径尺在搭舌上距箱口55mm处分别量取长和宽;以箱底与箱顶两面内摇盖间的距离量取箱高。

2.3抽样

2.3.1检验批:以同一原材料、同一结构普、同一工艺加工的瓦楞纸箱为一检验批,最大批量为25000个。

2.3.2抽样数量

外观抽样数量详见下表:

2.3.3.1重缺陷只要有一项不合格时,则该样箱为不合格,五个样箱中只要出现两个样箱不合格,则该批外观检验不合格。

2.3.3.2轻、重缺陷个数≤合格判定数,则该批外观检验合格,若大于合格判定数,则该批外观检验不合格。

Inspection operation instruction of carton

 

I. Subject content and applicable scope

1.1 this standard specifies the inspection items, inspection methods, sampling quantity and determination standards of corrugated cartons for commodity transportation packaging.

1.2 this standard is applicable to the inspection of single and double corrugated materials for packaging by sea, land and air.

Ii. Inspection items and methods

2.1 minor defects of appearance inspection

2.1.1 printing: the pattern and text on the box surface are correct, the color depth is consistent, and the position is accurate.

2.1.2 box nails: no rust spots, peeling and cracking, uniform spacing, single nail distance ≤55mm, nail distance ≤75mm, nail should be firmly nailed and thoroughly nailed.

2.1.3 cutting edge: no obvious burr, paper crack loss within the incision distance ≤8mm, length ≤12mm, and post lap Angle leakage ≤10mm in the box.

2.1.4 combination

2.1.4.1 the width of the tacking and lapping tongue is 35-40mm. The box nails should be tacked along the middle line of the tacking tongue and arranged in a neat manner, with deviation no more than 5mm.

2.1.4.2 the two joints of the carton shall be aligned, with the shear difference ≤4mm and the box body square.

2.2 heavy defects of appearance inspection

2.2.1 the size

2.2.1.1 the single limit deviation of length, width and height is +3 and -2cm.

2.2.1.2 measurement method: the carton is supported and formed, and the adjacent included Angle is 90 degrees. Measure the length and width of the carton at 55mm from the mouth of the carton on the lap tongue with the inner diameter ruler.Take the height of the case from the distance between the bottom and the two sides of the top.

2.3 sampling

2.3.1 inspection batch: corrugated cartons processed with the same raw material, the same structure and the same process are taken as one inspection batch, with a maximum quantity of 25,000.

2.3.2 sampling quantity
