摘要:为提升卷烟包装盒的成型能效以及闭合性能的问题,抽选20种卷烟包装小盒为测试样品,在温度(23±2)℃,相对湿度(50±10)%的条件下对其定量、厚度、弯曲挺度三项物理指标进行测试,同时建立提升卷烟包装盒闭合性能的一元模型。测试结果表明,纸张定量大的,厚度和弯曲挺度也大,包装盒成型越好。特别是当纵向弯曲挺度≥8 mN·m,且横向弯曲挺度≥4.5mN·m时,能有效解决和提升包装盒闭合性能问题。

Abstract: In order to improve the forming energy efficiency and closing performance of cigarette packaging boxes, 20 kinds of cigarette packaging boxes were selected as test samples, and they were quantified under the conditions of temperature (23±2) ℃ and relative humidity (50±10) %. Three physical index of quantitative thickness and bending stiffness were tested, and a unitary model was established to improve the closing performance of cigarette packages. The test results show that the larger the basis weight of the paper, the larger thickness and bending stiffness, the better shape of the packaging box. When the machine direction bending stiffness is ≥8 mN·m, and the cross direction bending stiffness is ≥4.5mN·m, closing performance of the packaging box can be effectively solved and improved.

当前,消费市场竞争日益激烈,对产品的内在品质和外在包装质量的控制和提升都提出了更高要求。在卷烟产品领域,卷烟包装盒大多采用折叠硬质纸张作为包装材质,其主要作用是将烟支储置于相对稳定的空间内,防止烟支受外力挤压变形。同时,起到一定密闭效果,避免烟支受潮、干燥、氧化或串味,以此来确保吸味品质的相对稳定性。目前,在消费者开启包装的过程中,由于反复开启使得许多包装盒在后续使用中出现关闭不严密的问题。为改善部分产品包装盒挺度和闭合性能不佳的问题,研究对包装纸的定量、厚度、弯曲挺度三项指标进行了实验和对比分析[1-2],在充分掌握云产卷烟在行业盒与条包装纸定量、厚度、弯曲挺度指标方面的基础上[3],有针对性的提出改进建议和方法,从而增强消费者的消费体验感、满意度,以及产品的市场竞争力。……
