PP hollow board turnover boxes are highly regarded for their waterproof and durable properties. However, improper cleaning and maintenance can still accelerate aging and cause damage. Below is a comprehensive cleaning and maintenance guide. Follow these steps to significantly extend the lifespan of your boxes!
I. How to Clean Dirty Hollow Board Boxes? (Correct Cleaning Steps)
1. Routine Dust & Light Stains
Method: Use a soft cloth or sponge dipped in room-temperature water to wipe the surface directly.
⚠️ Warning: Never use steel wool, abrasive scouring pads, or hard-bristle brushes. Although the surface of hollow boards is wear-resistant, prolonged friction with hard objects will cause scratches. Scratches not only affect aesthetics but also become breeding grounds for hidden dirt.
2. Stubborn Stains, Mud, or Fruit Juice Residue
Method: Add an appropriate amount of neutral detergent (e.g., dish soap) to the water. Wipe the stained area with a soft cloth, then rinse thoroughly with clean water.
⚠️ Warning: Strictly avoid strong acids, strong alkalis, or corrosive chemical solvents (e.g., thinner, heavy-duty cleaning powders). While PP plastic is acid and alkali resistant, prolonged exposure to highly concentrated corrosive liquids will cause the material to become brittle and discolored.
3. Odor Removal (e.g., after storing fresh produce or seafood)
Method: After washing, wipe the interior with diluted white vinegar or baking soda water, then place the box in a well-ventilated area to air dry naturally.
4. Post-Wash Drying
Method: After cleaning, always invert the boxes to drain or wipe them dry with a clean cloth, then let them air dry naturally in a cool, well-ventilated place.
⚠️ Warning: Never expose the boxes to direct sunlight or high-temperature baking. UV rays and extreme heat are the "number one killers" of plastic aging. Sun exposure will rapidly cause the hollow board to fade, become brittle, or even crack.
II. Daily Usage & Maintenance Standards (The Core to Doubling the Lifespan)
1. Standardize Stacking & Strictly Avoid Overloading
Every PP hollow board turnover box has a designated load-bearing limit. When loading fruits, vegetables, or other items, never exceed the rated weight to prevent box deformation or bottom rupture.
When stacking, ensure the upper and lower boxes are perfectly aligned and stable. Avoid tilting, as uneven weight distribution can cause the box to twist and warp.
2. Handle with Care & Avoid Violent Throwing
During handling and loading/unloading, always carry the boxes smoothly with both hands or use standardized forklifts/trolleys. Strictly prohibit throwing boxes from heights or forcefully dragging them across the ground. Severe physical impacts easily lead to cracked corners or broken internal support ribs.
3. Keep Away from Extreme Temperatures
The optimal operating temperature range for PP hollow boards is typically between -20°C and 60°C.
Avoid storing the boxes in extremely cold environments for extended periods (which makes the plastic brittle and prone to shattering upon impact) or near high-temperature heat sources (e.g., boilers, open flames), as this will cause the box to soften and deform.
4. Regular Inspection & Phasing Out
Conduct regular inspections of the turnover boxes. If severe deformation, extensive cracking, or compromised load-bearing structures are found, promptly retire and replace them. This prevents safety hazards such as cargo dropping during transit or personnel injuries.
Quick Maintenance Cheat Sheet:
Soft cloth only, no steel wool;
Neutral detergent for stains, keep it cool;
Air dry in shade, never bake in the sun;
Handle with care, avoid drops and hits;
Respect load limits, stack them straight;
Proper care ensures a longer life!
