Under the umbrella of Hefengli, dry ice insulated boxes are designed with the concept of caring for product temperature, conveying health and peace of mind, and caring for every degree of your well-being.

The industry's original PU+PE composite technology tightly integrates the molecular level, ensuring that the box is not easily delaminated or bulged, and the structure is stable and durable.

Unique PU foaming technology, precise regulation of molecular structure, achieving high-density closed cell structure, with a thermal conductivity coefficient as low as<22MW/m · k, effectively isolating heat conduction, and insulation performance 30% better than peers.

We independently control the entire production process of raw material selection, material formula, grinding and granulation, rotational molding and hot melting, and foaming molding, and have passed NSFIS09001, CE, ROHS and other system certifications to ensure the highest quality product service to customers.
