Custom 31L Food Grade Insulated Cooler Box
One-Piece Seamless Rotomolded Waterproof Box For Central Kitchen Food Delivery
Product Overview
This 31L large-capacity commercial thermal turnover container is manufactured via integral rotational molding process using thick food-contact LLDPE raw material to form a seamless outer shell. Filled with full high-density PU foam thermal insulation interlayer and matched with sturdy stainless steel spring latches and full-circle food-grade silicone sealing gaskets, this model offers a full open unobstructed inner cavity for bulk cooked meals and fresh ingredients storage.

We supply full OEM customization service, supporting custom box exterior color, surface silk-screen logo and external anti-slip convex rib layout.
