PFT005 Commercial Long-Lasting Rectangular PP+TPR Food Preservation Container 2-Pack Set with Overmolded Vented Lids (3700ml + 6800ml)

This high-capacity rectangular food preservation container 2-pack set (integrating 3700ml and 6800ml vessels) is purposefully engineered for high-density food inventory storage, large-scale culinary prep, and logistics demanding optimized space utilization. Fabricated from premium, impact-resistant food-grade PP, the storage system employs a co-injection molded PP+TPR overmolded lid featuring an airtight blue center pressure-relief valve. Component ① (30.3x21.3x9.5cm) is calibrated at a 284.5g weight, while Component ② (35.5x26.5x11cm) is reinforced at 437.1g. Its latch-less, streamlined rectangular geometry with radiused corners significantly drives up horizontal and vertical stacking density in freezing vaults and transport crates. The dual-size configuration permits complete nested storage for empty shipping optimization. Distributed in a professional B2B bulk packing standard (Sticker + Paper card, 4 sets/ctn, GW 3.52KGS), this set serves as an elite functional SKU for global wholesale sourcing and commercial food operations.

Technical Highlights
Heavy-Duty Rectangular Structural Mass: The large 3.7L and 6.8L deep-body capacities are paired with rigid wall masses of 284.5g and 437.1g respectively. The structural engineering of the flat rectangular base distributes heavy solid or liquid payload weights evenly, neutralizing localized stress concentration and preventing container wall bowing under vertical loads.

Latch-Less Seamless TPR Overmolded Friction Seal: Eliminating mechanical side latches, the closure system fuses a continuous blue TPR elastomer border directly onto the rigid PP lid plate during injection molding. It achieves an airtight seal via precise interference fit and rubber friction, stripping out the risk of hinge fatigue or breakage while producing a flat, zero-clearance side profile for seamless box-to-box alignment.

High-Density Tapered Nesting System: Modeled with a rigorous draft angle, the 3700ml container drops completely into the 6800ml container when empty. This internal nesting capability cuts shipping volumes by half, which, combined with a calibrated 372842.8cm master carton (4 sets/ctn), maximizes container payload efficiency and reduces per-unit ocean freight expenditures.

Integrated Steam Toggle Valve & Standardized Packing: A blue toggle valve centered on the lid panel instantly equalizes interior negative pressure when extracting containers from sub-zero storage and provides automatic pressure release during high-power commercial microwave reheating. Delivered in a standardized supply-chain format (NW 3.00KGS, GW 3.52KGS per carton), it ensures accurate barcoding, swift inventory audits, and immediate commercial deployment.

Recommended Applications
Walk-In Refrigerator & Central Commissary Stocking: The straight-walled rectangular footprint offers superior space economy over cylindrical storage, making it excellent for institutional kitchens to hold large batches of prepped produce, marinated proteins, and commissary bases.

Cold-Chain Food Processing & Fresh E-Commerce Turnover: Scaled perfectly for agricultural prepackers and meal-prep manufacturers to bulk-package cut produce, frozen protein blocks, and prepared wholesale meals, relying on the friction-fit rubber seal to withstand vibration during long-distance shipping.

Global Wholesale Importers & Bulk Retailing Kits: The clear-view box walls combined with clean, low-profile lids deliver excellent shelf organization and merchandising clarity. Packaged in tight 4-set master cases, it is fully optimized for cross-border B2B digital marketplaces, container-load distribution, and catering equipment wholesale catalogs.
