Heavy corrugated box detection is an important link in the production and trade sales of enterprises. Especially in the online mall, trading platform, need to provide heavy corrugated box qualified test report. And the heavy corrugated box inspection report usually needs to entrust the third party inspection organization to carry out.

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。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 corrugated box is divided into class I carton and class II carton. Type I cartons are divided into slotted type A, sleeve type B and semi slotted box with cover C. Class II carton refers to other heavy-duty corrugated box products except class I carton. Such as wooden frame carton, wrapping carton and so on. Heavy duty corrugated boxes are required to have clear printed pictures and texts. The surface of the boxes should be clean and tidy. There should be no obvious defects such as loopholes or corners. At the same time, there should be clear information about the types, codes, production dates and manufacturers of the cartons.

Ⅰ類重型瓦楞紙箱檢測

Class I heavy corrugated box inspection

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 weight of the contents, the maximum comprehensive size, the minimum comprehensive weight of corrugated board, the minimum burst strength, the minimum puncture strength and the minimum edge pressure strength. The weight of corrugated paper core should not be less than 127g / m2. Double corrugated box, corrugated type should be A-A type, three corrugated box 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

Class II heavy corrugated box inspection

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 cartons shall meet the requirements of double corrugated board with d-1.5 or triple corrugated board with t-1.2 specified in GB / t6544. There are many inspection requirements for class II carton, such as reinforcement material, dimension and tolerance, indentation, quality of slotting and cutting knife edge, quality of hand hole or handle, quality of shaking cover, nailing quality, bonding quality, compressive capacity, mechanical impact energy, moisture-proof and fireproof performance of the carton need to meet the requirements.

所以總結來講，重型瓦楞紙箱的關鍵檢測項目主要有耐破強度、戳穿強度、變壓強度、空箱抗壓能力、抗沖擊能力。其中抗沖擊能力檢測主要包括了跌落沖擊試驗、水平沖進試驗、可控水平沖擊試驗等項目。業(例如：壓片機，糖衣鍋，混合機，粉碎機，篩粉機等工藝設備)的粉去除。

Therefore, in summary, the key inspection items of heavy-duty corrugated box mainly include bursting strength, puncture strength, variable pressure strength, compressive capacity of empty box and impact resistance. The impact resistance test mainly includes drop impact test, horizontal impact test and controllable horizontal impact test. Industry (such as: tablet press, sugar coating pot, mixer, grinder, sifter and other process equipment) powder removal.
