What types of consumer-grade plastic storage crates are available?

Classification by structural design
Fixed/Standard Model: A single, integrated unit that cannot be disassembled; it features a sturdy structure with high load-bearing capacity and resists slipping when stacked, making it ideal for the long-term, stationary storage of heavy items.

Collapsible Model: Can be quickly folded flat when not in use, reducing the storage volume of empty crates by 75% to save space-an excellent choice for households with limited living area.

Nestable/Interlocking Model: Features a patented design allowing empty crates to nest within one another; this saves 50% of the space when stacked and makes lifting and handling easier.

Mesh/Ventilated Model: Designed with open vents or mesh sides for excellent airflow; suitable for storing fruits, vegetables, and fresh produce to prevent spoilage caused by trapped heat or moisture.

Fully Enclosed Model: A completely sealed design without holes or vents; waterproof and dustproof, it is suitable for storing liquids or moisture-sensitive items, such as seasonal clothing and bedding.
