Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-4, the puncture-resistant degradable medical garbage bag of the present invention has the structural features: the puncture-resistant degradable medical garbage bag is characterized in that: the puncture-resistant degradable medical garbage bag comprises a buffer layer 11, a puncture-resistant layer 12 connected below the buffer layer, a barrier layer 13 connected below the puncture-resistant layer 12, and a protective layer 14 connected below the barrier layer 13, so that a garbage bag body 1 of the puncture-resistant degradable medical garbage bag is formed, and the method is implemented by the following steps:

first, the buffer layer 11 is a biodegradable foam material. The biodegradable foam material can be prepared by the person skilled in the art according to the biodegradable foam material with the publication number CN108559234A or the biodegradable foam material with the publication number CN 109096525A.
