Abstract

The invention discloses a full-biodegradable material capable of being applied to paper laminating and a manufacturing method thereof. The full-biodegradable material is prepared from, by weight, polylactic acid, PBAT, a compatibilizer, a coupling agent, paraffin, glycerinum and sorbitol. The manufacturing method of the full-biodegradable material comprises the following steps of 1, weighing the polylactic acid, the PBAT, the compatibilizer, the coupling agent, the paraffin, the glycerinum and the sorbitol for uniform mixing and stirring; 2, putting the raw materials which are uniformly mixedinto a pelletizer for mixing, melting, extrusion, and grain-sized dicing after cooling to prepare full-biodegradable plastic particles. The price of the full-biodegradable material is nearly the sameas that of common plastic thin film, and the material is a green material capable of being completely degraded; the material is processed into the thin film through equipment and then applied to paperlaminating.

Description

technical field [0001] The invention relates to packaging materials, in particular to a fully biodegradable material applicable to paper coating and a manufacturing method thereof. Background technique [0002] Disposable paper cups, paper bowls and other disposable tableware are essential supplies in people's daily life, especially in the catering industry, where the usage of disposable paper cups and paper bowls is very large, but the plastic on many disposable tableware currently used Membranes are almost always non-degradable materials. Due to their unique properties, non-degradable plastic materials are not easy to degrade and disappear in the natural environment after use and disposal, and they will not degrade for hundreds of years, causing visual pollution and destroying ecological balance. [0003] With the requirements of technological and social development, people research and develop new thermoplastic degradable materials to replace the use of traditional plast...
