触感型无底涂剂BOPP预涂基膜的研究
|
摘要
通过选择膜层材料及厚度并对制膜过程关键技术点进行控制,在四层共挤BOPP生产线研制出触感型无底涂剂BOPP预涂基膜。该薄膜收卷无折皱、粘连,平均厚度偏差低于2%,触感面触觉舒适度良好,复合功能面无需底涂剂可与EVA热熔胶直接复合,剥离强度达0.33 N/15 m。
The soft touch BOPP thermal laminating base film requiring no primer was prepared on four layer co-extrude BOPP production line by selecting out the optimum materials and thickness for each layer, as well as controlling the key technologies during the production process. The offline film roll has no defects like crease or conglutination, and the film thickness deviation is below 2%. The soft touch face of this film has a good touch sense comfort, and the EVA hot-melting adhesive can be coated on the composite function surface layer with a peeling strength of 0.33 N/15 mm in no need of primer.
