Zusammenfassung:The invention relates to the field of packaging materials, in particular to application of lignin in preparation of degradable foaming packaging materials. The lignin is applied to the degradable foaming packaging material and can effectively replace degradable resin, so that the cost is reduced; and the modified esterified lignin can act on PBAT or PBST and other aromatic polyesters, so that thebonding strength between the degradable resins is further enhanced, the properties of the material are improved, the lignin consumption is further increased, and cost is further lowered. 本发明涉及包装材料领域,具体涉及木质素在制备可降解发泡包装材料中的应用。本发明将木质素应用到可降解发泡包装材料中,能够有效替代可降解树脂,从而降低成本;且改性后的酯化木质素能够作用于PBAT或PBST等其他的芳香类聚酯,从而进一步提高可降解树脂之间的结合强度,提高材料的性能,也能进一步提高木质素的用量,进一步降低成本。
