Inline Plastics Value Pack Sandwich Clamshell Plastic Container VPP756
Lower concern. Bare PP clamshell unlikely to contain intentional PFAS.
Standard polypropylene food container with no reported grease-resistant coating or PFAS treatment. No brand disclosure available, but bare PP is a lower-risk material for food contact.

Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This is an uncoated polypropylene (PP, #5 plastic) clamshell container. PP is a relatively stable thermoplastic that does not contain BPA or phthalates by design. Uncoated PP has minimal leaching risk at room temperature or during cold storage. The main concern with PP is thermal stress: repeated heating or contact with hot/fatty foods can degrade the polymer and cause microplastic release, though this is most problematic in microwave use rather than passive food contact.
The brand's record and disclosure
Springpack (parent company Inline Plastics) has no public sustainability certifications, PFAS disclosure statements, or documented recalls for this specific product line as of available records. The company does not advertise BPA-free or other chemical restrictions on this value-pack line. No third-party testing or transparency reports are on file. The silent stance on PFAS and chemical policy is typical for commodity food-service packaging suppliers but reflects limited transparency overall.
How it compares in its category
Uncoated PP clamshells are among the safest single-use food containers for cold and ambient storage. They perform equivalently to other generic PP foodservice clamshells (e.g., Solo, Pactiv brands) and better than PET (#1) or PVC (#3) alternatives in terms of leaching risk. This is a budget option; premium alternatives (compostable fiber, glass) eliminate plastic hazards entirely but at higher cost and weight. For short-term deli/bakery use, PP clamshells are the baseline safe choice in the disposable category.
If you buy it
Keep containers out of the microwave and away from direct heat, hot foods above 50°C (122°F), and prolonged contact with fatty foods (oils/butter degrade PP faster). Use for cold storage only: salads, bakery, deli items. Replace if you see cloudiness, cracking, or surface wear, as these indicate polymer breakdown. Recycle after use (PP #5); do not reuse for liquids or foods if cracks develop. Store in cool, dark conditions to minimize UV and thermal stress.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
BPA / Bisphenol-A
Polypropylene does not use BPA as a monomer or additive by standard manufacturing. No BPA exposure reported for this material class.
Phthalate plasticizers
PP is inherently rigid and does not require phthalate plasticizers. No phthalates are present in standard PP clamshell formulations.
Microplastic release on heating/degradation
PP clamshells can degrade and shed microplastics if exposed to heat above 60-70°C, microwaved repeatedly, or if the container develops cracks or stress fractures. Risk is low for cold storage but increases significantly with misuse or aging.
Antimony leaching from polyester / pigments
Antimony is a catalyst residue found in PET and polyester, not PP. Uncoated PP clamshells do not use antimony catalysts and pose no antimony risk.
Additive migration (colorants, UV stabilizers, slip agents)
Uncoated PP may contain FDA-approved additives (e.g., slip agents, antioxidants, UV absorbers) that can migrate into food under stress or heat. Migration is minimal at room temperature but increases with fatty foods or thermal cycling. No specific contaminant testing for this product line is on record.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
