Any smellable off-gassing or residual odors exuding from unused/new Grove bags is contamination, adulteration, shouldn't be there; and is worse when don't know what it is.
From my familiarity with multi-layer laminated bags used very widely in the (bio)pharmaceutical industry, makes me wonder about leachable & extractables (L&E; what can diffuse out of the bags), an unending safety/regulatory concern for the industry. This includes residual solvents (carcinogens such as benzene?), partially polymerized content (e.g., reason silicone is flexible is 30-40% or more is unreacted liquid silicone), undesired polymerization reactants, residual polymerization catalysts, the adhesives and chemically-reacting cross-linkers used (to 'tie' the layers of laminated plastics together), the lubricants and 'slip agents' used to prevent sheets from sticking to rollers and themselves, antioxidants, inner and outer surface polishes/coatings used, what about the printing (nasty solvents used?), etc.
As a Grove bag user, I want to know what is the odor multiple users have reported? And what can Grove tell us about related safety/toxicity? How should end users deal with the problem, and are smelly bags returnable (even if used? returnable to Grove or the seller?), will there be a recall.........etc.
Something else to perhaps ask Grove: Do the bags and materials and processes used meet US and/or EU biopharmaceutical manufacturing/GMP or food grade? For ex., do the bags meet FDA food contact/additive standards? Have any leachate/extractables analytical and safety/toxicity testing and assessments been done with the bags?
