Abstract

The invention belongs to the technical field of plastic processing, and particularly discloses a plastic product for food packaging and a preparation process of the plastic product. The plastic product mainly comprises honey, thermoplastic resin, mica, graphite, dibutyl phthalate, stearate and foaming agents, and raw materials are processed to prepare the plastic product. The honey serves as one of main components for preparing the plastic product, usage amount of other chemical additives is decreased, the honey is added, so that the plastic product does not easily age and is stable in performance, degradation of the plastic product can be facilitated in soil, environmental pollution caused by the plastic product is reduced, and potential hazards of chemical reagents to human bodies are reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to a plastic product used for food packaging and a preparation process thereof. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers as raw materials through addition polymerization or polycondensation reactions. Existing plastic products are mainly prepared and processed by using resin as raw material and assisting other additives. The plastic products prepared by the prior art are non-degradable or difficult to degrade, causing serious white pollution to the environment; in addition, the use of a large number of chemical reagents will also cause potential harm to the human body, especially the plastic products used for food packaging. Contents of the invention [0003] The present invention intends to provide a plastic product that is easily degraded while reducing the potential risk of harm to the human body and...
