product feature
Material: Typically made from high-impact, durable thermoplastics Polypropylene (PP). These materials offer excellent resistance to impact, moisture, chemicals, and temperature variations, ensuring a long service life.
1). Half-fold collapsible construction: The foldable side panel design shrinks idle height to merely 140mm, greatly lowering vacant storage occupation when not in use. Unfolded height reaches 480mm for large-capacity storage.
2). Reinforced grid wall structure: Thickened grid panels enhance compression resistance and load capacity, supporting stable multi-layer stacking without deformation.
3). Integrated side carrying handles: Built-in grip slots on two sides allow single-person lifting and moving, optimizing daily handling efficiency.
4). Repairable modular parts: All side panels and hinge connectors can be replaced separately instead of discarding the whole crate, complying with PPWR reuse rules and extending service life.
Note：Modular repairable design, individual side panels & hinge connectors replaceable, compliant with EU PPWR reuse requirements.
Modular Repairable Construction – Replace Only Damaged Parts, No Whole‑Crate Scrapping
Conventional folding crates adopt one‑piece injection‑molded hinges integrated with side panels. Hinges are the most vulnerable component during high‑frequency handling, repeated folding, cold‑storage impact and transportation collision. Once hinges crack or break, the entire crate must be discarded, even if base and remaining panels are still in good condition. This brings high recurring procurement cost and excessive plastic waste, which fails to meet EU PPWR reuse obligations.
Our crate features detachable modular hinges and side panels as separate spare parts.
- Broken hinge: replace only hinge connectors, keep main body
- Dented or cracked single side panel: swap this individual panel, reuse other components
- The main base can stay in service for much longer service life.
This design fully complies with EU PPWR requirements for repairability and waste reduction. It delivers high value for returnable‑packaging leasing projects, automotive component circulation and high‑intensity warehouse operations, a feature rarely available among competing standard folding bins.

FAQ
Q: Which standard pallets does this crate fit? Is it compatible with roller conveyor systems?
A: The outer footprint is 400×300 mm, perfectly matching Euro‑pallet 800×600 and 1200×800. On a 1200×800 euro‑pallet, it can be arranged in 4 columns × 3 rows. On an 800×600 euro‑pallet, layout is 2 columns × 2 rows. With a flat base and dimension tolerance of ±5 mm, it works directly with automated roller conveyor lines. Note that only same‑direction stacking is permitted; 90‑degree cross‑stacking is not supported.
Q: How many empty folded crates can be loaded into one 40HQ container?
A: Folded empty dimension: 400×300×70 mm. The theoretical loading quantity is around 4200‑4400 pieces. For real‑world shipment, considering pallet gaps, stretch film and loading clearance, the practical budget reference is 3900‑4100 pieces. The exact number varies based on palletized or bulk‑loading mode. Custom container‑loading layout is available on request.
Q: What is its stacking load capacity? How many layers can be stacked when fully loaded?
A: Each crate has a unit load capacity of 10 kg, with a maximum stacking load of 50 kg from upper‑layer weight. A maximum of 4‑5 layers is recommended under fully‑loaded conditions. Avoid continuous 5‑layer storage for more than 3 months to prevent permanent base creep deformation. Operating temperature ranges from ‑18℃ to +70℃. Reduce stacking layers when used in cold‑storage environments.
Q: What does repairable modular parts mean? Are spare parts available separately? Does it comply with EU PPWR?
A: Hinge connectors and side panels are detachable independent spare parts. If hinges or side panels are broken or dented, only the damaged component needs replacement instead of scrapping the whole crate, while the main base can stay in service. Hinge and side‑panel spare parts can be ordered in separate bulk lots. This repairable design fulfils EU PPWR requirements for repairability and waste reduction, well‑suited for returnable packaging leasing projects.
Q: What benefits does the half‑fold structure bring compared with conventional four‑side folding crates?
A: The half‑fold mechanism enables quick fold and unfold operation by one single operator. Integrated built‑in side handles support one‑person lifting. Folded height reaches only 70 mm, cutting empty‑crate volume by 71%. Net weight is merely 1.15 kg, lighter than ordinary four‑side folding crates of equal size, lowering labour handling cost and return‑logistics expenses.
