Abstract

The invention discloses a high-strength environment-friendly carton and a preparation method thereof. The high-strength environment-friendly carton is finally obtained through pulping, papermaking and hot press molding. The paper base is reinforced through the synergistic effect of the two kinds of environment-friendly fibers, the mechanical strength of the carton is enhanced, the adopted polylactic acid / polycaprolactone composite fibers have biodegradability, polylactic acid and polycaprolactone are mixed, so that the brittleness of polylactic acid is reduced, the toughness is enhanced; and the coconut shell fibers modified through magnesium oxide act together, therefore, the high-strength environment-friendly carton has excellent mechanical strength.

Description

technical field [0001] The invention belongs to the technical field of carton processing, and in particular relates to a high-strength environment-friendly carton and a preparation method thereof. Background technique [0002] With the rapid development of the Internet economy, more and more people choose online shopping as a channel for purchasing items. These online products are sent to consumers by express delivery, and these products need to be packaged during the delivery process. , Cartons are often used in the packaging process of commodities. A high-strength, wear-resistant carton can well protect these commodities from damage due to various factors during transportation. In addition, after these cartons are used, they will more or less cause unnecessary pollution to the environment during the recycling process due to the recycling process. Contents of the invention [0003] In order to deal with the problems mentioned in the background above, the present inventio...
