对同一规格、不同手孔形状的重型装饰灯具外包装瓦楞纸箱的抗压强度进行了试验,以探讨提手孔形状对纸箱抗压强度的影响。在提手孔形状满足舒适度的前提下,对5 种形状的提手孔进行了试验。试验结果表明,针对瓦楞纸箱抗压强度损失而言,弧形提手孔强度损失最少,梯形提手孔最大,跑道形、山形和半圆形提手孔对纸箱抗压强度的影响程度相差不大。

Compressive strength of corrugated boxes for heavy decorative lights packaging was tested. The corrugated boxes had different shape of handing hole. 5 kinds of shape of handing hole were tested on condition of meeting comfort level requirements. The results showed that corrugated box with arc-shaped handing hole has the minimum loss of compressive strength; trapezoidal-shaped handing hole causes the maximum loss; for the runway-shaped, hill-shaped, and half-round-shaped, their loss has little difference.
