中文摘要:
      目的 用水溶PVA薄膜代替不可降解BOPP薄膜作为胶带基材。方法 试验分别测试PVA和BOPP薄膜(未涂布)的拉伸强度和断裂伸长率,涂布水性压敏胶的PVA和BOPP薄膜以及涂布热熔胶的PVA薄膜的拉伸强度、断裂伸长率、初粘性和180°剥离强度。结果 BOPP薄膜的拉伸强度为34.32 N/cm,略高于PVA薄膜,但是BOPP薄膜的断裂伸长率低于PVA薄膜;BOPP胶带、PVA热熔胶带、PVA水性胶带的拉伸强度分别为48.38,63.68,32.94 N/cm,BOPP胶带的断裂伸长率同时低于PVA热熔胶带和PVA水性胶带;BOPP胶带的初粘性略高于PVA水性胶带;BOPP胶带、PVA热熔胶带、PVA水性胶带的180°剥离强度分别为1.58,6.48,2.63 N/cm。结论 与BOPP胶带相比,PVA胶带的拉伸强度、断裂伸长率、初粘性和180°剥离强度均可满足封箱胶带对力学性能的要求。
英文摘要:
      The work aims to substitute the non-degradable BOPP film with water-soluble PVA film as a tape substrate. Tensile strength and elongation at break of PVA film and BOPP film were respectively tested. Tensile strength, elongation at break, initial stickiness and 180° peel strength of PVA and BOPP films applied with water-based pressure sensitive adhesive and of PVA film applied with hot-melt adhesive were tested. The tensile strength of BOPP film was 34.32 N/cm, slightly higher than that of PVA film, but the elongation at break of BOPP film was lower than that of PVA film. The tensile strengths of BOPP tape, PVA hot-melt tape and PVA water-based tape were 48.38, 63.68 and 32.94 N/cm, respectively. The elongation at break of BOPP tape was lower than that of PVA hot-melt and water-based tapes. The initial stickiness of BOPP tape was slightly higher than that of PVA water-based tape. The 180° peel strength of BOPP tape, PVA hot-melt tape and PVA water-based tape were 1.58, 6.48 and 2.63 N/cm, respectively. Compared with BOPP tape, the tensile strength, elongation at break, initial stickiness and 180° peel strength of PVA tape can meet the requirement for mechanical properties of packaging tape.
