The plastics used to make the bags in which we package our frozen fish and some organic foods are FDA-certified food grade.
Lower temperatures make it less likely that plastic will leach from packaging to food. Accordingly, we recommend that you store all plastic-packaged food (e.g., our dried fruits and nuts) in the dark, at cooler temperatures (e.g., between 60 and 75 degrees F).
Although the bags containing our frozen seafood come in direct contact with these products, plastic from frozen packaging is unlikely to transfer to frozen seafood.
Like most plastic food packaging, most of our plastic bags contain a plastic called polyethylene terephthalate (PET).
Certain types of phthalates (orthophthalates) are the subject of health concerns related to endocrine disruption.
Although “polyethylene terephthalate” (the plastic) and “phthalate” (the additive) may sound alike, they are chemically dissimilar.
PET is not an orthophthalate, nor does PET contain orthophthalates.
Polyethylene terephthalate (PET) is currently deemed safe by US and EU health agencies for use in plastic food packaging.
