Stock Your Home 8-Inch Clamshell Takeout Containers
Greaseproof takeout containers carry PFAS risk, skip if concerned.
Polystyrene clamshells frequently receive grease-resistant coatings that may contain PFAS to repel food oils. Lakeland provides no PFAS disclosure or independent testing for this line.

What Stock Your Home 8-Inch Containers is made of, ingredients and materials
Stock Your Home clamshells are polystyrene (PS, #6 plastic), a petroleum-derived polymer known to leach styrene monomers, especially when heated or in contact with fatty foods. The 'greaseproof coating' is typically a fluorochemical treatment designed to repel oils and moisture, which is the primary PFAS exposure vector in this product category. Polystyrene is rigid and clear but degrades under heat and UV, potentially releasing both styrene and coating particles over time.
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.
Styrene monomer leaching
Polystyrene naturally leaches styrene, particularly when heated above 70C or exposed to fatty, acidic, or alcoholic foods. Cold foods at room temperature pose minimal acute risk but chronic low-level exposure over years of use is a known concern.
PFAS
Fluorochemical grease barriers in takeout containers are established sources of PFOA, PFOS, and other legacy PFAS compounds. Migration increases with heat, fat content, and container age. Lakeland provides no statement that this coating is PFAS-free or uses newer alternatives.
Source, ATSDR ↗Microplastics
As polystyrene containers age, embrittlement and cracking release small plastic fragments into food, especially if reused, microwaved, or exposed to sun. Risk is elevated if containers are used repeatedly over months.
Source, EPA ↗Coating flaking or particle ingestion
Greaseproof coatings can degrade and separate from the polystyrene substrate over time, especially with thermal stress or mechanical wear, potentially introducing coating particles into food.
What’s reassuring
BPA & bisphenols
Polystyrene clamshells do not typically contain BPA/BPS as part of the base polymer, though some greaseproof additives or manufacturing aids may include other endocrine disruptors; manufacturer transparency is absent.

The brand's record and disclosure
Lakeland (UK-based homewares retailer) has not publicly disclosed chemical composition, PFAS-free certification, or commitments to phasing fluorinated coatings on food packaging. The brand does not appear on major chemical transparency databases or sustainability reports specific to food-contact materials. No known recalls or chemical safety incidents are on record for this specific product line.
How it compares in its category
Polystyrene clamshells with greaseproof coatings are industry standard for takeout and remain cheaper than alternatives (bagasse, molded fiber, uncoated cardboard), but carry documented PFAS and styrene concerns. Competitors like Footprint and some major foodservice suppliers now offer alternatives reported as PFAS-free or plant-based. These Stock Your Home containers lack third-party greaseproof certification (e.g.compostability, PFOA-free claims) that would differentiate them as having lower concern.
If you buy it
Use only for cold or room-temperature foods; do not microwave or fill with hot liquids, as heat accelerates styrene and coating leaching. Replace if containers become cloudy, brittle, or visibly degraded. Limit exposure time for fatty foods (oils, meats, cheese) as lipophilic PFAS compounds migrate preferentially into fats. Store in a cool, dark place away from sunlight to slow polymer degradation.
