What type of materials does the term "combo of plant and no plant materials" typically refer to?

The term "combo of plant and no plant materials" typically refers to mixed commodities. Mixed commodities involve combinations of products that include both plant-based materials and non-plant components. This could be items such as packaged foods that contain agricultural products along with other materials, like packaging or preservatives, which may not come from plant sources. Understanding mixed commodities is important in phytosanitary practices as it helps identify potential risks associated with the introduction of pests and diseases through various pathways.

In contrast, biodegradable products specifically denote items that can decompose naturally and do not necessarily involve a combination of plant and non-plant materials. Colored packaging materials refer solely to the appearance of containers or wrappings, without indicating the composition of the materials. Composite materials are generally engineered materials made from two or more constituent materials, which may not accurately reflect the idea of a mixture of plant and non-plant materials as intended in the question. This distinction highlights why mixed commodities is the most fitting choice regarding the combination of different material types.
