FAQ

Q: What temperature range can this product withstand?

A: The product can operate stably within a wide temperature range of ‑18°C to 65°C, making it suitable for use in fresh cold‑chain logistics. Its typical service life is 3‑5 years. If customers have special temperature requirements, the product can also be customized accordingly.

Q: Are the parts of the collapsible crate prone to damage? What is the typical service life?

A: Reputable brands reinforce the critical connection points of their collapsible crates. Taking ZNKIA as an example, its products are made of high‑quality impact‑resistant PP material with enhanced structural design, and the normal service life can reach 3‑5 years. When purchasing, pay attention to the brand and quality, and avoid low‑priced inferior products.

Q: Can parts be replaced if they get damaged?

A: Yes. Zhengji collapsible crates are assembled from multiple components. If a part becomes damaged during use, the corresponding component can be replaced directly without scrapping the entire crate, thereby extending its service life.

Q: Are lids available for the product? Can the lid be locked?

A: Lids are available for some models. The lid is typically designed with a snap‑fit (clip) mechanism and must be manually opened after closing to prevent accidental opening. If you require a model with a lid or have special locking requirements, please contact the sales team for details.

Q: What is the minimum order quantity?

A: Our standard stock colors are green and blue. For these in-stock items, orders can be placed starting from as few as 1 piece. For color customization, the MOQ is generally 1,000 units or more. If you only need samples or small-batch purchases, we recommend contacting our sales team directly for specific policies.

Q: Can colors be customized or logos printed on the crates?

A: Yes. Stock products are typically available in blue or green, but other colors such as red, yellow, green, transparent, and more can be customized. The collapsible crates can also be customized with screen printing, mold engraving, and tag clips.

Q: What is the delivery lead time for ZNKIA collapsible crates?

A: The delivery lead time depends on the specific situation. If there is regular stock available, shipment can be arranged according to the customer's requested time. For bulk orders (e.g., 1,000 pieces), it generally takes 3‑7 working days from production to shipment.

Q: How can I get an accurate delivery lead time?

A: We recommend contacting the ZNKIA sales team or online customer service directly with your specific product model, quantity, color, and customization requirements. The sales team will confirm the accurate delivery lead time based on your actual situation.

Q: What is the lead time for customized products?

A: Customized products involve multiple steps, including color formulation, mold modification or new mold development, trial molding, sample confirmation, and more. Especially for brand‑new mold development, the process goes through design drawings, formal mold manufacturing, trial molding, sample confirmation, and finally mass production. The entire process generally takes from 40 days to several months. If only simple modifications are made based on an existing mold, the timeline can be significantly shortened.

Q: What material is used for the product? Is it safe?

A: The product is made of impact‑resistant PP (polypropylene), and the connecting parts are made of virgin nylon material. The product meets food‑grade packaging requirements and can be in direct contact with fresh produce.

Q: Is the product environmentally friendly and recyclable?

A: Yes. The product features an all‑plastic design with no metal, ceramic, or other material components. At the end of its life cycle, it requires no sorting or disassembly and can be 100% directly recycled. In addition, ZNKIA has established a full life‑cycle service system covering design, mold development, production, sales/leasing, recycling, and remanufacturing.

Q: Is the crate stable when stacked? Will it tip over?

A: The crate is designed with stacking slots at the bottom and stacking rims at the top, which interlock tightly to form a stable stacking system. Some models also feature a patented staggered stacking design, allowing the stack to remain stable even at a 30° tilt without toppling. It is recommended to follow the manufacturer's recommended number of layers when stacking, and to use the crates on level ground or inside a truck.

Q: Can it be integrated with automated equipment?

A: Yes. Some collapsible crates feature a flat‑bottom design, with appearance and dimensions that meet standardized requirements, allowing them to be used with automated equipment such as sorting machines, conveyor belts, stacking robots, and more. The crates can also be equipped with chips or RFID tags, and can be customized as needed.

Q: What is the load capacity and stacking height of the collapsible crates?

A: Load capacity varies by model, generally ranging from 10 to 30 kg. Taking the fruit and vegetable collapsible crate ZJKN604022W‑HS as an example, each crate can hold 15‑20 kg and can be stacked 8‑10 layers high. Most models can be stacked up to 5 layers.

Q: What precautions should be taken when using the product in the cold chain?

A: The product can be used within a wide temperature range of ‑18°C to 65°C. However, the toughness of the plastic may decrease at low temperatures, so it is recommended to handle it with care and avoid severe impacts.

Q: How are ZNKIA collapsible crates packaged for shipment?

A: ZNKIA collapsible crates are typically shipped in folded condition to maximize space savings. Depending on order quantity and shipping method, packaging options include carton boxes, stretch film wrapping, or palletized full-pallet shipments. Custom packaging requirements can be discussed with the sales team when placing an order.

For long-haul transportation, empty crates can be folded on the return trip to effectively utilize space for other cargo, reducing empty-return costs.

A: Yes. ZNKIA collapsible crates are made of impact‑resistant PP material, featuring a pin‑joint design and dovetail joint structure, with load‑bearing side walls and dense ribbing for added strength and durability. Generally, each crate can hold 10‑25 kg and can be stacked 5‑10 layers high, making them suitable for long‑haul transportation over 1,000 kilometers. The structure is sturdy and not prone to collapse.
