Double-Sided Plastic Pallet

Product Identification & Specifications

A Double-Sided Plastic Pallet (reversible pallet) features identical, load-bearing top and bottom decks. Both surfaces incorporate symmetrical grid or closed-deck patterns, permitting the pallet to be inverted to distribute wear or used interchangeably within automated material handling systems.

Matching structural ratings to operating environments prevents catastrophic failures in high-bay racking and automated storage.

Closed-Loop Automated Warehousing (AS/RS): Select solid-top, steel-reinforced models. Flat bottom decks prevent roller jamming on gravity conveyors, while internal steel bars limit dynamic deflection to under 5 mm under a 1,000 kg rack load.

Bagged Material & Chemical Stacking (Sacks, Resins, Powders): Select grid-surface double-sided pallets. The symmetrical grid pattern distributes point loads evenly and restricts slippage of woven PP sacks during transit.

Cold Storage & Freezer Environments (below -20°C): Specify Virgin Impact-Modified PP. Standard recycled HDPE turns brittle below freezing; virgin copolymer formulations preserve impact resistance under sub-zero forklift impacts.

Validated Use Cases
High-Rack Storage: Edge-racking systems where pallets rest exclusively on front and rear beams without bottom deck intermediate support.

Heavy Industrial Transport: Stacking up to 5 tiers high in warehouses handling automotive components and heavy metal parts.

Hygienic / Pharmaceutical Zones: Washdown facilities requiring steam sterilization and chemical resistance without moisture absorption.

Operational Constraints
Pallet Jack Limitation: The fully closed bottom deck restricts low-profile manual pallet jack wheel entry. Operations must utilize forklift trucks, reach trucks, or high-lift transpallets with fork pockets.

Concentrated Point Loads: Cargo weight must be distributed across the deck surface. Concentrated loads exceeding 10 kg/cm² require rigid top-sheet interlayers.

Manufacturing consistency depends on controlled processing parameters.

Injection Molding Machinery:

Produced on 2,800-ton to 4,000-ton computer-controlled injection molding presses. High clamping tonnage guarantees uniform wall thickness and eliminates internal sink marks in thick rib sections.

Resin Handling:

Gravimetric blending systems meter virgin resin, color masterbreak, and UV stabilizers within a ±0.1% accuracy tolerance prior to the plasticizing barrel.

Quality Control & Testing Protocols:
Melt Flow Index (MFI) Testing: Performed per ISO 1133 on every incoming raw material lot.

Static Deflection Test: Sample pallets loaded to 150% of rated capacity for 24 hours to quantify permanent deformation.

Drop Impact Testing: Dropped loaded pallets from a 1.5-meter height onto concrete at -20°C to verify crack propagation resistance.

When auditing a double-sided plastic pallet manufacturer, verify the following baseline capabilities:

Tooling Ownership: Confirm whether the supplier owns the injection molds or outsources tool maintenance. In-house mold maintenance ensures parting line flash is controlled and wall thickness remains uniform.

Raw Material Traceability: Request Certificates of Analysis (CoA) verifying polymer density (0.941 - 0.965 g/cm³ for HDPE) and melt index values.

Load Test Reports: Require third-party structural test reports (e.g., TÜV, SGS, or ASTM D1185) explicitly detailing edge-racking deflection curves under sustained load.

Customization Capability: Verify capacity to embed RFID tags (LF/UHF), mold permanent company logos, or adjust anti-slip rubber insert durometer (Shore A 60–70).

Specification Confirmation: Submit payload weight, rack beam span, forklift type, and environmental temperature parameters.

Drawing & FEA Review: Receive 2D/3D CAD drawings and Finite Element Analysis (FEA) stress distribution reports within 48 hours.

Sample Verification: Pilot samples shipped via air freight for physical rack-fit testing and dynamic load trials.

Volume Production & Inspection: Bulk manufacturing executed with pre-shipment inspection (PSI) reports covering drop testing, dimension verification, and weight tolerance (±2%).

Provide the following parameters to generate a precise quotation:
Target Quantity: (Minimum order quantity typically 1 container load / approx. 200–300 units for custom sizes).

Required Dynamic & Racking Load: (e.g., 1,200 kg dynamic, 1,000 kg racking).

Destination Port / Incoterms: (FOB Ningbo/Shanghai or CIF destination port).

Material Grade Requirement: Virgin HDPE/PP vs. Industrial Recycled Grade.
