PP Turnover Box: Waterproof & Eco-Friendly Reusable Packaging for Fruit, Vegetable and Seafood Cold Chain
May 25, 2026
Made of premium food-grade PP hollow board material, these non-toxic turnover boxes are safe for direct contact with fruits and seafood for cold storage and circulation. Featuring sturdy, lightweight and compression-resistant structures, they remain undeformed in temperatures ranging from -40℃ to 80℃, resisting brittleness and damage in cold storage and low-temperature transportation.
Superior waterproof, moisture-proof and salt-corrosion resistance define its core cold chain advantages. The inert PP material has an ultra-low water absorption rate of 0.01% with fully sealed structures. It withstands long-term exposure to seawater, ice water and condensation without softening, mildewing or deformation. Acid and salt corrosion resistant, the smooth box surface allows easy cleaning and repeated sterilization, effectively preventing fresh food contamination and reducing transportation losses.
Mainly designed as foldable hollow board boxes, the products feature stable load-bearing and durability, suitable for seafood long-distance cold chain, fruit and vegetable sorting, and store distribution. The foldable structure greatly saves warehouse and return transportation space. Custom options including reinforced edges and inner partitions effectively avoid collision and extrusion damage, ensuring intact product delivery.
PP cold chain turnover boxes deliver outstanding cost performance. With a 3–5 year service life and hundreds of reusable cycles, they eliminate disposable packaging waste and cut long-term operational costs. Fully recyclable and eco-friendly, they comply with green logistics and ESG standards. Widely applied in fresh harvesting, cold storage and cold chain delivery, they are essential packaging for modern standardized fresh logistics.
Select models based on scenarios: food-grade low-temperature resistant types for refrigerated environments, reinforced types for heavy-duty long-distance transportation, and foldable types for space-limited sorting and delivery. Avoid direct sunlight exposure, overloading and hard scratches to extend service life, ensuring stable waterproof, hygienic and low-temperature transportation performance.
