摘要
随着人们环保意识的逐渐提高,环保友好、节能减排已成为全球人们关注的重点,在限塑令、禁塑令背景下,以纸代塑是实现环境保护和可持续发展的主要方式.但由于纸基材料表面疏松多孔的结构,小分子的水和气体很容易通过孔隙渗透和润湿纤维,不能满足包装材料的阻隔功能要求,同时纸张没有热封性能,无法通过加热自粘制袋的方式达到工业化生产的要求,且其在机械强度方面难以与塑料相媲美.本文主要从防潮性、阻气性、热封性和机械强度四个角度综述了生物基涂层改性纸基包装材料的研究.
Abstract
With the growing environmental consciousness among people worldwide,eco-friendliness and energy conservation have emerged as key global concerns.Amidst policies of plastic restriction and prohibition,substituting paper for plastic stands out as a principal approach to environmental protection and sustainable development.However,the loose and porous surface structure of paper-based materials allows for easy permeation and wetting of fibers by small molecules of water and gases,which does not satisfy the barrier functionality required for packaging materials.Additionally,paper lacks the heat-sealable properties necessary for self-adhesion through heat in industrial production processes,and its mechanical strength is hard to match that of plastics.This review primarily synthesizes research on the bio-based coating modification of paper-based packaging materials,focusing on four aspects:moisture resistance,gas barrier properties,heat sealability,and mechanical strength.
