Avoid abrasive pads or harsh chemicals like chlorine bleach (unless compatible with the plastic grade), as these can scratch or weaken the material over time.

• For heavy-duty cleaning, use non-abrasive brushes or pressure washers at low settings
• Ensure boxes are completely dry before storage to prevent mold or odor retention
• Check manufacturer guidelines before using industrial sanitizers or autoclaving

Proper Storage Conditions

To preserve structural integrity, store plastic boxes in a cool, dry, and shaded environment. Extreme temperatures—both hot and cold—can cause warping, embrittlement, or deformation, especially in large or thin-walled custom designs.

• Avoid direct sunlight and proximity to heating units or radiators
• In cold climates, allow boxes to acclimate before loading to prevent cracking
• Store indoors when possible; use UV-protected covers if outdoor storage is unavoidable

Avoid Overloading

Every custom-sized box has a maximum load capacity based on wall thickness, material grade, and design. Exceeding this limit—even occasionally—can lead to permanent deformation, stress fractures, or collapse during transport.

• Distribute weight evenly across the base to prevent tipping or warping
• Use internal dividers or trays to support heavy or unevenly shaped items
• Consult engineering specs for dynamic (moving) vs. static (stacked) load ratings

Critical note: Overloading voids warranties and compromises safety in automated handling systems.

Stacking Guidelines

Stacking is one of the greatest advantages of modular plastic boxes—but only when done correctly. Improper stacking can lead to crushing, misalignment, or toppling, especially with non-standard or oversized containers.

• Always follow the manufacturer’s recommended stacking height and weight limits
• Use boxes with interlocking rims or stacking feet for stability
• Inspect boxes regularly for cracks or warping, especially in lower tiers
• Rotate stock (FIFO) to prevent long-term compression damage

Safety first: Never stack beyond eye level without proper support or barriers.
