PUVIP PU Integrated Box

The PUVIP PU Integrated Box is our mainstream mid‑tier passive cold‑chain container, designed to strike a great balance between thermal performance, mechanical durability and project budget. It integrates VIP vacuum insulation inserts inside integral‑molded rigid PU foam housing, removing spliced joints that become weak points for heat transfer in assembled boxes. The one‑shot molding process improves overall sealing and structural rigidity, resisting deformation under regular stacking during logistics operations.

Its insulation capacity sits between high‑end aerogel VIP boxes and basic XPS aluminum‑foil boxes, perfectly matching most conventional pharmaceutical shipments with medium transit duration. It handles medicines, lab samples and medical consumables that need stable 2‑8℃ temperature environment. The outer PU layer resists scratch and moisture penetration; internal space can be re‑configured according to customers’ actual packing objects, accommodating various sizes of PCM ice bricks and medicine packaging.

Full OEM support covers outer dimension adjustment, internal partition design, logo printing and color customization. Each batch undergoes simulated temperature cycling test to confirm real holding‑time output, helping customers select matched PCM ice brick models for their specific transport routes. Widely adopted by regional pharmaceutical distributors, medical trading companies and small‑to‑mid biotech enterprises. Compared with full VIP premium boxes, it optimizes total procurement cost without sacrificing core cold‑chain reliability, serving as a highly practical option for bulk daily medical shipping projects.
