What synthetic mesh materials are pyramid bags often constructed from?
Synthetic mesh materials like nylon or polyethylene terephthalate (PET).
While the goal of the pyramid shape relates to infusion mechanics, the material chosen for its construction introduces a separate set of variables, particularly concerning purity and environmental impact. To achieve the necessary structural integrity required to maintain the three-dimensional shape when wet, manufacturers often utilize synthetic mesh materials. The two most commonly cited examples of these materials are nylon and polyethylene terephthalate, often abbreviated as PET. The use of these plastics raises health concerns for some consumers regarding the potential for microplastics or other chemicals to leach into the hot water during the steeping process, although definitive research on long-term impacts from food-grade plastics is still emerging and evolving.
