Our invertable nesting stack crates are specially engineered for supermarket, fresh produce and cold chain logistics operations. Featuring a unique reversible buckle structure, these plastic baskets support two working modes without extra equipment. Place the crate forward for firm interlocking multi-layer stacking when loaded with fruits, vegetables, meat and seafood; simply flip each crate 180° upside down, and they fully nest into one another, slashing empty crate storage and backhaul shipping space by more than 50%. Constructed from thick food-grade PP plastic, the crates stand up to frequent heavy-duty circulation, low-temperature cold storage and regular washing, making them a cost-effective upgrade to single-function standard crates and tilt baskets for all retail logistics links.Wide Application Scenarios,Supermarket backstock turnover, fresh section storage and shelf restocking,Fruit & vegetable wholesale markets, community group-buying distribution centers,Seafood, meat and cooked food cold storage sorting & transportation,Clean vegetable processing plants and agricultural product packaging workshops,Warehouse storage for retail accessories, daily goods and hardware parts。
