LEM Freezer Sheets

Poor

Freezer wrap coating likely contains PFAS, but specifics unknown.

Verdict · SkipFreezer sheets present unclear PFAS risk in the moisture barrier coating; brand transparency on material composition is absent. Use for freezing only, avoid heat contact.

LEM Freezer Sheets are plastic film wraps for frozen food storage. No PFAS disclosure is available; food packaging grease-resistant coatings often contain PFAS, though the exact composition remains unconfirmed.

🫧

Microplastic release or degradation

Freezer sheets are stable at cold temperatures. Risk emerges if sheets are reused, over-stretched, or exposed to temperature cycling; fragmentation into microplastics is theoretically possible over years of use but not confirmed in peer-reviewed studies for this specific product.

70/ 100
🍳

Moisture-barrier coating migration into food

If the barrier coating contains fluorinated compounds or other slip agents, prolonged contact with fatty foods (oils, butter, cheese) at freezer temperatures could allow slow migration. This risk is plausible but not quantified for LEM Freezer Sheets; brand silence on coating chemistry prevents definitive assessment.

70/ 100

Coating degradation and leachate from thawed condensation

When frozen foods thaw or condensation forms on sheets during temperature cycling, water-soluble coating components may leach. Risk is low at freezer temperatures but increases if sheets are repeatedly moved between freezer and room-temperature storage.

What’s reassuring

🍼

BPA & bisphenols

No public reports of BPA or BPS in LEM Freezer Sheets. Polyethylene and polypropylene base materials do not require BPA; if present, it would appear in colorants or processing aids, which is not documented for this product.

The full breakdown

What it's made of and why it matters

LEM Freezer Sheets are plastic film, most likely polyethylene (PE) or polypropylene (PP) with an applied moisture-barrier coating to prevent freezer burn and ice crystal formation. The coating is the uncertainty, grease-resistant coatings in food packaging commonly use fluorinated compounds (PFAS family), though some manufacturers now use non-fluorinated alternatives. At freezer temperatures (below 0°C), the base plastic itself is chemically stable and unlikely to leach; the risk emerges if the product is exposed to heat or if the barrier coating migrates into fatty foods over extended storage.

The brand's record and disclosure

Deli Wrap has not published public material safety data sheets, third-party certifications (BPA-free, PFAS-free), or disclosed coating chemistry for this product. No recall history is on record for LEM Freezer Sheets specifically. The brand's silence on PFAS and fluorochemical use is consistent with many regional food-packaging manufacturers, but it means independent verification of the barrier coating is unavailable. Absence of certification does not confirm presence of PFAS, only that the manufacturer has not committed to transparency.

How it compares in its category

Freezer storage films occupy a middle ground, parchment paper and silicone mats avoid polymer leaching entirely but lack moisture-barrier performance. Uncoated polyethylene or polypropylene alone allows sublimation and freezer burn. LEM Freezer Sheets likely perform better than generic plastic wrap for freezer use but worse than vacuum-sealed bags. Major branded alternatives (Glad, Saran, store-generic versions) similarly do not disclose barrier-coating composition, making category-wide comparison difficult. Products explicitly labeled PFAS-free or certified by third parties (NSF, SQF) remain rare in this subcategory.

If you buy it

Use only for freezer storage at or below 0°C; do not place near stovetops or use to wrap foods intended for baking or reheating. Inspect sheets for punctures, tears, or visible degradation before use; replace if the surface becomes sticky, cloudy, or flaky, which signals coating breakdown. Store in a cool, dry location away from direct sunlight. For fatty foods (cheese, butter, cured meats), consider vacuum sealing as an alternative if PFAS concern is high, or rotate sheets to limit storage duration beyond 3-4 months.
