FULLY-DEGRADABLE HEAT-INSULATING ENVIRONMENTALLY-FRIENDLY PACKAGING BAG FOR EXPRESS DELIVERY

摘要

The present invention relates to a fully-degradable heat-insulating environmentally-friendly packaging bag for express delivery, comprising a bag body, wherein the bag body has double fabric layers, including an inner layer of hot-rolled non-woven fabric, an outer layer of coated non-woven fabric, and a sandwich layer wherein the sandwich layer is filled with heat-insulating fibers. The bag body is using PLA biodegradable plastic material as base material, and the bag body is produced by spinning PLA, manufacturing thin non-woven fabrics, coating non-woven fabric, printing, forming a bag, and filling the fibers. The heat-insulating environmentally-friendly packaging bag for express delivery, in order to ensure high purity of degradable materials, free of adding any harmful chemicals in making process, which adopts a technique of hot fusion ultrasonic fusion, to avoid adding non-degradable auxiliary materials, achieve full degradation in real sense.
