PP Hollow Panel Document Storage Box is a versatile, eco-friendly desktop organizer specifically designed for modern office environments.

Combined with its foldable and space-saving portability, it is the ideal choice for boosting office efficiency and maintaining a tidy workspace.

Core Material & Eco-Friendly Features

Food-Grade PP Raw Material: The main body is made of Polypropylene (PP), known for its high strength, impact resistance, ease of coloring, and excellent surface gloss, meeting the safety standards for daily office supplies.

Non-Toxic, Odorless, & Recyclable: PP material is inherently non-toxic, odorless, and free from harmful plasticizers, ensuring safe use. The product is fully recyclable after disposal, aligning with green office concepts.

Moisture & Mold Resistant: The hollow structure effectively isolates moisture, preventing documents from getting damp or moldy. It is especially suitable for humid regions or environments prone to moisture, such as near windows or pantries.

Structural & Functional Design Highlights

Hollow Mechanical Structure, Lightweight & Strong: The interior features a honeycomb or grid-like hollow design that significantly reduces overall weight while maintaining excellent load-bearing capacity, making it effortless to carry.

Foldable Design for Space Saving: When not in use, the box can be easily flattened and folded, reducing its volume to 1/5 of its original size. This makes it convenient to store in drawers, cabinets, or corners, making it perfect for space-limited desks or mobile work scenarios.

Large-Capacity Open Design: The spacious interior can accommodate A4 folders, notebooks, contracts, reports, and various other document sizes. The side handle holes allow for easy grabbing and moving.

Multiple Colors to Match Office Aesthetics: Available in classic colors including blue, gray, white, and black, it seamlessly blends with different styles of office furniture to enhance visual unity on your desktop.

Application Scenarios & User Value

Office Desktop Organization: Perfect for categorizing project materials, client files, and meeting minutes, keeping important documents visible at a glance and reducing search time.

Meeting Room Temporary Storage: Ideal for quickly organizing and distributing materials before meetings and collecting them afterward, keeping the venue neat and orderly.

Home Study & Learning Areas: Students or freelancers can use it to organize homework, test papers, and design blueprints, helping to cultivate good storage habits.

Corporate Administration & Archiving: Serves as a departmental document transit box, supporting batch archiving and circulation to improve administrative efficiency.

Usage & Maintenance Tips

Cleaning Method: Wipe with a damp cloth to remove dust and stains. For stubborn dirt, gently clean with a neutral detergent. Avoid using strong acid or alkaline solvents.

Load Capacity Warning: Although structurally robust, it is recommended not to exceed a load of 5kg per box to prevent long-term deformation from excessive weight.

Folding Operation: For first-time use or after long-term storage, gently press the four corners to restore its 3D shape and ensure structural stability.
