Uline · Grease-Resistant Deli & Butcher Paper
ULINE Glassine Paper Rolls
Skip until brand discloses coating composition and PFAS status.
Glassine paper is treated for water and grease resistance, which may contain PFAS in typical formulations. Greenline provides no disclosure of coating chemistry or PFAS testing.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Glassine coatings commonly use PFAS "forever chemicals" (PFAS) or fluorochemical-free alternatives; Greenline has not disclosed which. PFOA/PFOS are known persistent bioaccumulators, but newer PFAS and fluorocarbon alternatives are often not labeled. Without transparency, assume possible but unconfirmed.
Source, ATSDR ↗Mineral oil or paraffin migration from coating
Some glassine coatings incorporate food-grade mineral oil or hydrocarbon waxes for grease resistance. While generally recognized as safe at trace levels, migration into fatty foods or at elevated heat is not tested for this specific product. Brand does not disclose coating base material.
Coating degradation and particle shedding
Glassine coatings can crack or flake if rolled tightly, exposed to moisture, or heated unevenly. Microscopic paper and coating fragments may then migrate into food, especially high-fat or acidic items. Degraded rolls should be discarded.
What’s reassuring
Recycled paper contamination
No information available on whether Greenline glassine uses virgin or recycled pulp. Recycled paper can carry legacy persistent contaminants (PFAS, inks, adhesives); recycled-content status is not disclosed. If virgin pulp, this hazard is minimized.
Bleach or optical brightener residues
Commercial paper is typically chlorine-bleached and may contain optical brighteners (fluorescent whiteners) to enhance appearance. No bleach process or brightener information is disclosed for this product. Residues are generally low but unconfirmed here.
The full breakdown
What it's made of and why it matters
Glassine is densely calendered (compressed) paper that creates a smooth, grease-resistant surface without chemical coating on the paper fibers themselves. The barrier properties come from the paper structure, not added polymers. However, commercial glassine products often include a topcoat or sizing agent to enhance moisture and oil resistance, and this coating composition is what determines safety profile. Greenline's specific coating formula is not publicly disclosed, making complete hazard assessment impossible.
The brand's record and disclosure
ULINE Greenline is ULINE's sustainability-focused private label; ULINE does not publicly disclose PFAS use in Greenline paper products or confirm fluorocarbon-free coatings. No third-party certifications (FDA, compostability, chemical-free claims) are listed on product pages reviewed. The brand has not published a PFAS policy or coating transparency statement. This silence is a material red flag in an industry where PFOA/PFOS and newer PFAS have historically been standard in grease-barrier coatings.
How it compares in its category
Glassine paper ranks lower-risk than plastic films (which often contain phthalates or BPA) and wax-coated paper (which can migrate mineral oils or paraffin). However, it sits in a middle tier compared to uncoated paper or explicitly PFAS-free certified alternatives like some compostable or silicone-coated brands. Premium competitors (e.g., If You Care, Baking Parchment) publish PFAS-free or mineral-oil-free claims; Greenline does not. Glassine's actual safety depends entirely on what that barrier coating is, which is unknown here.
If you buy it
Use only for dry foods, baking at temperatures below 420F (glassine begins to yellow and degrade above this), and short-term storage. Do not use with fatty or acidic foods at high heat, as coating integrity is unknown and may accelerate leaching. Store rolls in a cool, dry place to prevent moisture absorption and coating stress. Replace if paper yellows, becomes brittle, or shows visible wear; these are signs the barrier is failing.
