Crystal PET Airtight Fresh Box | 3 Sizes · Green Seal Lock — Factory Direc

Features

1. Triple-Material Visual System : Crystal PET (visibility) + fluorescent green PP seal frame (precision signal) + matte black PP latch (authority) — the three materials are deliberately chosen for their aesthetic contrast as much as their functional roles. The result is a container that reads as premium before anyone touches it or opens a lid.

2. Dual-Layer Precision Seal Frame : The fluorescent green PP frame is a dedicated structural element — not a gasket, but a precision-engineered channel that the smoked PET lid panel locks into from above. This creates two independent sealing surfaces at the lid perimeter, significantly outperforming single-gasket designs for long-duration refrigerator storage.

3. Oval Pressure Valve : The camera-lens-style oval valve on the lid center allows manual pressure equalization after the latches are engaged — preventing the vacuum seal from making the lid impossible to open when refrigerated contents cool and contract. One press. Balance restored. Lid opens normally.

4. Wide-Span Center Latch Handles : The matte black latch handles span the full width of the long sides — functioning simultaneously as lid locking mechanisms and as ergonomic grip points for carrying the fully loaded container. The wide span distributes carrying load across four fingers simultaneously, comfortable even at 5150ml full capacity.

5. Three-Size Vertical Coverage System : 1950ml for daily individual storage, 3200ml for family portion management, 5150ml for batch cooking and weekly meal prep cycles. The three sizes share a consistent visual identity — a fridge stocked with all three reads as a curated storage system rather than a collection of mismatched containers.

6. Crystal PET Vertical Rib Body : The precision vertical rib pattern on the PET body provides a non-slip grip surface, adds structural rigidity to the thin-wall PET, and creates a light refraction effect that makes the container appear to glow from inside — a passive visual premium that requires no additional surface treatment.
