重型瓦楞紙箱分為Ⅰ類紙箱、Ⅱ類紙箱之分。Ⅰ類紙箱分為開槽型A型、套合型B型、半開槽型箱體加箱蓋C型。Ⅱ類紙箱是指除了Ⅰ類紙箱之外的其他重型瓦楞紙箱產品。如木框架紙箱、裹包式紙箱等等。
Heavy corrugated boxes are divided into class I and class II. Class I cartons are divided into slotted type A, sleeve type B and semi slotted type C with box cover. Class II carton refers to other heavy corrugated carton products except class I carton. Such as wooden frame carton, wrapping carton and so on.
重型瓦楞紙箱都要求有明顯清晰的印刷圖文，箱體表面感覺整潔，沒有明顯漏洞或包角等缺陷，同時也有明確的紙箱種類、代號、生產日期、制造廠商等信息。
Heavy duty corrugated boxes are required to have obvious and clear printed graphics, the surface of the box feels clean and tidy, and there are no obvious defects such as loopholes or corners. At the same time, there are also clear information about the type, code, production date and manufacturer of the box.
Ⅰ類重型瓦楞紙箱檢測
Detection of type I heavy corrugated box
Ⅰ類紙箱的物理性能檢測項目主要有內裝物質量、綜合尺寸、瓦楞板更小綜合定量、更小耐破強度、更小戳穿強度、更小邊壓強度。瓦楞紙芯定量不應該小于127g/㎡。雙瓦楞紙箱，楞型應該為A-A型，三瓦楞紙箱楞型應該為C-A-A型或A-A-A型。如果是防水紙箱，則紙板更外層應該涂有防水樹脂的防水紙板。
The physical performance test items of class I carton mainly include the maximum quality of the contents, the maximum comprehensive size, the minimum comprehensive quantity of corrugated board, the minimum bursting strength, the minimum puncture strength and the minimum edge pressure strength. The core weight of corrugated paper should not be less than 127g / m2. Double corrugated box, corrugated type should be A-A, three corrugated box corrugated type should be c-a-a or a-a-a. If it is a waterproof carton, the outermost layer of the cardboard should be coated with waterproof resin.
Ⅱ類重型瓦楞紙箱檢測
Detection of class II heavy corrugated box
Ⅱ類紙箱物理性能檢測要求符合GB/T6544 規定的D-1.5以上的雙瓦楞紙板或T-1.2以上的三瓦楞紙板。Ⅱ類紙箱檢測要求比較多，如紙箱的加強材料、尺寸與公差、壓痕、開槽與裁切刀口質量、手挽孔或提手質量、搖蓋質量、釘合質量、粘合質量、抗壓能力、機械沖擊能能、防潮、防火性能等等都需要滿足其規定。
The physical properties of class II carton shall meet the requirements of double corrugated board with d-1.5 or above or triple corrugated board with t-1.2 or above specified in GB / t6544. There are many inspection requirements for class II carton, such as the reinforcement material, dimension and tolerance, indentation, slotting and cutting edge quality, hand hole or handle quality, swing cover quality, nailing quality, bonding quality, compression resistance, mechanical impact energy, moisture resistance, fire resistance and so on.
