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(jué)整潔，沒(méi)有明顯漏洞或包角等缺陷，同時(shí)也有明確的紙箱種類(lèi)、代號(hào)、生產(chǎn)日期、制造廠(chǎng)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(lèi)重型瓦楞紙箱檢測(cè)

Detection of type I heavy corrugated box

Ⅰ類(lèi)紙箱的物理性能檢測(cè)項(xiàng)目主要有內(nèi)裝物質(zhì)量、綜合尺寸、瓦楞板更小綜合定量、更小耐破強(qiáng)度、更小戳穿強(qiáng)度、更小邊壓強(qiáng)度。瓦楞紙芯定量不應(yīng)該小于127g/㎡。雙瓦楞紙箱，楞型應(yīng)該為A-A型，三瓦楞紙箱楞型應(yīng)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(yīng)該涂有防水樹(shù)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.

Detection of class II heavy corrugated box

Ⅱ類(lèi)紙箱物理性能檢測(cè)要求符合GB/T6544 規(guī)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(lèi)紙箱檢測(cè)要求比較多，如紙箱的加強(qiáng)材料、尺寸與公差、壓痕、開(kāi)槽與裁切刀口質(zhì)量、手挽孔或提手質(zhì)量、搖蓋質(zhì)量、釘合質(zhì)量、粘合質(zhì)量、抗壓能力、機(jī)械沖擊能能、防潮、防火性能等等都需要滿(mǎn)足其規(guī)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.
