Prepara Latchlok Click Food Storage Container with Divider – 6.2 Cups

Good

Rigid plastic food container; PFAS risk low but unconfirmed by brand.

Verdict · BuyBPA-free plastic container with low PFAS risk and no reported leaching concerns; standard food-storage safety profile.

Prepara makes food storage containers from plastic. No PFAS disclosure available; rigid plastic containers typically lower concern than coated cookware or treated textiles, but composition details remain absent.

What Prepara Latchlok Click Food Storage is made of, ingredients and materials

Prepara Latchlok is a rigid plastic food-storage container; the brand claims BPA-free formulation but does not disclose the full polymer type or alternative plasticizer chemistry. Without specification of whether the base is polypropylene (PP), polyethylene terephthalate (PET), or another copolymer, the identity of any replacement for BPA remains opaque. Rigid, opaque food-grade plastics of this class are generally formulated to resist leaching under normal cold storage, but chemical composition transparency is absent from public product information.

🍼

BPA & bisphenols

Brand claims BPA-free but does not name the replacement compound. Cold-storage leaching risk is lower for rigid PP or PET, but without disclosure of the actual polymer and plasticizer, residual leaching cannot be ruled out, especially if the container is old, scratched, or exposed to heat.

Microplastics

Rigid plastic containers can shed microparticles if the surface degrades from scratches, thermal stress, or UV exposure. No specific degradation data for Prepara containers exists in the public domain, but all food-contact plastics pose this risk over their lifetime.

🍳

Leaching from polymer or coatings under thermal stress

If the container is placed in warm storage, dishwasher, or microwave contrary to intended use, leaching of residual monomers or additives increases. Prepara does not specify heat-stability limits, so misuse risk is present.

⏳

Polymer degradation and discoloration over time

Consumer reports note that some rigid plastic food containers yellow, cloud, or crack after 1-2 years of normal use. This suggests additive migration, UV sensitivity, or material fatigue. No specific degradation timeline for Prepara containers is documented, but the class risk is established.

⚠️

Mold and bacterial growth in seals and dividers

The Latchlok divider and seal design create crevices where moisture and food residue can accumulate if not thoroughly dried. Incomplete cleaning between uses can harbor pathogens or mold, independent of the plastic composition itself.

The full breakdown

The brand's record and disclosure

Prepara does not publish detailed material safety data, third-party certifications (such as FDA letter-of-no-objection for specific polymers), or substantiation of BPA-free claims beyond the assertion itself. No established safety controversies or recalls specific to Prepara food containers are on record. The brand's silence on PFAS, full polymer identity, and plasticizer alternatives reflects a common industry stance of minimal chemical transparency in the consumer segment.

How it compares in its category

Rigid plastic food-storage containers occupy a large market segment; Prepara's position is mainstream without distinction for chemical transparency. Competitors such as OXO and Rubbermaid offer similar BPA-free claims but likewise do not routinely disclose polymer composition or alternative plasticizer data. Glass, stainless steel, or ceramic alternatives eliminate polymer leaching risk entirely but add cost and breakage liability. Prepara sits in the standard-assurance tier, BPA-free labeling without deeper chemical documentation.

If you buy it

Store only cold or room-temperature foods; do not use in microwave, dishwasher, or direct sunlight for extended periods, as heat and UV can degrade polymer coatings and increase leaching risk. Hand-wash and dry promptly after use; inspect regularly for cracks, discoloration, or clouding, which signal polymer degradation and warrant replacement. Do not store oils, alcohol-based liquids, or acidic foods long-term, as these can soften plastics over time. Replace every 2-3 years or sooner if visible wear develops.
