提高纸塑复合袋剥离力的有效途径

VALID APPROACH OF INCREASING PEEL STRENGTH OF COMPOSITE PAPER & PLASTIC SACK

针对纸塑复合袋剥离力对产品质量的影响,从原料、生产工艺等方面分析了影响纸塑复合袋剥离力的因素,如树脂的氧化程度不够、涂覆树脂不合适、基材粗糙度不够等,进而指出了提高剥离力的有效途径,即让树脂得到充分氧化、对涂覆树脂进行改性、对编织布和牛皮纸进行电晕处理等。

Owing to effect of peel strength on quality of composite paper & plastic sack, influence factors of peel strength such as lack oxidation of resin, improper coated resin, and inadequate rough degree of the bag surface etc were analyzed. They are some valid approaches of increasing peel strength that resin is oxidated sufficiently,and resin is modified, and woven cloth and kraft paper is submitted to a corona treament etc.
