Springpack · Disposable Food Service Containers
Stock Your Home 6-inch Clamshell Take Out Food Containers
Skip; food-contact packaging coatings often contain PFAS, unverified.
Springpack discloses nothing about PFAS or coatings on these takeout containers. Grease-resistant food packaging typically uses fluorinated compounds; no third-party testing or claims provided.

The full breakdown
What it's made of and why it matters
Stock Your Home clamshells are molded fiber (likely bleached kraft pulp or recycled fiber) with a grease-resistant coating applied to the interior surfaces. This coating prevents grease and moisture from degrading the pulp structure, but grease-resistant treatments in food packaging are a known vector for PFAS chemicals, which migrate into fatty foods. The molded fiber base itself is chemically inert under normal cold-storage conditions, but the coating's composition is typically proprietary and unverified by the brand.
The brand's record and disclosure
Springpack is a private-label manufacturer with no publicly available sustainability certifications, PFAS disclosure statements, or third-party testing documentation for these containers. No recalls specific to this product are on record. The brand does not publish ingredient lists for coatings or commitments to PFAS-free alternatives, making it impossible to verify the safety profile of the grease-resistant layer.
How it compares in its category
Molded fiber clamshells sit in the middle ground of food-packaging safety: safer than plastic clamshells for leaching concerns, but the coating chemistry is often opaque. Some competitors (e.g., certified compostable or plastic-free brands) disclose PFAS status or use mechanical barriers instead of chemical coatings. Standard uncoated pulp containers eliminate coating risk but fail with greasy foods; this product trades that tradeoff for unknown chemical exposure.
If you buy it
Limit use to cold and room-temperature foods (salads, baked goods, sandwiches without added oil). Do not use for hot foods, as heat accelerates migration of coating chemicals into food. Replace containers after 6-12 months of storage or if you observe visible degradation, discoloration, or odor from the coating. Contact Springpack directly to request PFAS and coating documentation before purchase; silence on this question is a red flag for food-contact packaging.
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.”
PFAS in grease-resistant coating
Molded fiber clamshells commonly rely on fluorochemical or PFAS-based coatings to repel grease and water. Springpack provides no disclosure; industry practice suggests high probability, especially if product is not explicitly marketed as PFAS-free.
Migration of coating chemicals into fatty or acidic foods
While molded fiber itself does not leach, the grease-resistant coating can transfer to oily or acidic foods (cheese, dressings, citrus) at room temperature and more readily when heated. Risk is lowest for dry or cool foods.
Degradation of coating integrity over time
Repeated moisture exposure, storage temperature fluctuations, and contact with acidic foods can wear or flake the coating, potentially releasing particulates or exposing untreated pulp to food contact. Visible wear is a signal to replace.
Formaldehyde or chlorine residues from pulp bleaching
Modern pulp manufacturing minimizes these residues, and molded fiber is not known to off-gas significantly under normal conditions. No recalls or reports specific to Springpack containers.
Microplastics or coating particles if heated
Microwave or oven use (even brief) may degrade the coating layer and release small particles into food. These containers are not designed for heat and should not be used in ovens or high-temperature applications.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
