Study on release coating process and coated surface properties of domestic high-breathability medical cover paper
摘要
Abstract
To achieve domestic substitution of medical high-breathability cover paper sub-strates and develop high-strength,high-permeability medical packaging materials,this study comparatively analyzed the coatability of domestic and imported base papers.A single-layer release coating process with pore-forming agent hybrid primer was adopted,investigating air permeability,surface properties,wettability,and interlayer adhesion evolution between the base paper and composite release layer under varying formulation ratios.Results indicate that at 3.0 g·m-2 coating weight with 3%pore-former ratio,the composite release-coated paper exhibits excellent coatability:air permeability 733 mL·min-1,uniformity index 88.43,smoothness 3.85 s,roughness 8.14 μm,Cobb60 21.3 g·m-2,contact angle 123 °,interlayer adhesion(MD/CD:0.156 N.m/0.148 N.m).After applying 6.0 g·m-2 hot-melt adhesive,permeability remains at 275 mL·min-1,and heat-sealing with PET achieves peel strength of 5.13~5.90 N·15 mm-1 with clean delamination.This study overcomes the air permeability control limitations of imported base paper,providing key technological support for industrial-scale production of high-performance domestic medical cover paper.关键词
