Product Range and Specialties of Ningbo Hengli Plastic Products Co,. Ltd.

The catalogue offers a series of rotomolded cooler boxes fabricated primarily from polyethylene (PE) and polyurethane (PU) composites. In the broader market, rotomolded coolers are commonly produced from high‑density polyethylene (HDPE) or linear low‑density polyethylene (LLDPE) with wall thicknesses of 3‑5 mm to achieve insulation values of 30‑40 mm when double‑walled. Standard industry grades include UV‑stabilized PE for outdoor durability and food‑grade PE that complies with FDA 21 CFR 175.105 for direct contact with consumables. Typical specifications for similar products include an interior temperature retention of 20 °C below ambient for 24 hours, a weight range of 5‑15 kg depending on capacity, and a waterproof seal rated IPX4 or higher.

Buyers often request additional variants such as reinforced handles, lockable lids, or custom branding. Larger models (45 QT‑65 QT) may incorporate a steel frame or reinforced corners to support heavier loads and facilitate wheeled transport. The product line’s emphasis on portable capacities aligns with market demand for both consumer camping gear and professional catering equipment, where compliance with food safety standards and durability under repeated use are critical.

Common Incoterms include FOB Ningbo or CIF destination ports, allowing buyers to manage customs clearance and inland transport. Chinese manufacturers often provide pre‑inspection reports from agencies such as SGS or Intertek, which can be requested to verify material composition, insulation performance, and safety markings before shipment.
