The invention discloses a degradable polylactic-acid-based composite material used for a recyclable plastic express box. The polylactic-acid-based composite material is prepared by using polylactic acid as a base material and jute fibers as a reinforcing material for enhancing, toughening and modification; and the polylactic-acid-based composite material comprises the following raw materials in parts by weight: 65-85 parts of the polylactic acid, 10-20 parts of chopped jute fibers, 5-10 parts of polyethylene glycol, 1-5 parts of nano titanium dioxide, and 1-3 parts of polycarbodiimide. The degradable polylactic-acid-based composite material used for the recyclable plastic express box provided by the invention adopts the green environment-friendly and degradable polylactic acid as the basematerial, and a certain amount of the treated jute fibers are added, so that the strength and toughness of the composite material are enhanced, the production costs are reduced, and processing is easier. 本发明公开了循环利用塑料快递盒用可降解聚乳
