The packaging must maintain sub-zero temperatures across weeks of transit. It must resist moisture from melting ice and condensation. It must survive port handling, container stacking, and customs inspection \u2014 all while keeping its structural integrity at -18\u00b0C, where conventional materials become brittle and fail.<\/p>\n<p>For decades, the industry default was\u00a0<strong>EPS (expanded polystyrene) foam boxes<\/strong>\u00a0\u2014 lightweight, decently insulating, and cheap. But EPS is now being banned across the globe under single-use plastics directives. The EU&#8217;s SUPD, Canada&#8217;s 2023 ban, and state-level US legislation are forcing seafood exporters to find alternatives \u2014 urgently.<\/p>\n<p>PPBOXY&#8217;s\u00a0<strong>PP corrugated frozen fish shipping box<\/strong>\u00a0is that alternative.

Waterproof surfaces withstand wash-down sanitation. Custom printing ensures full traceability from processing batch to destination.<\/p>\n<p><strong>Cold Storage &amp; Freezer Warehouses<\/strong>: Boxes maintain dimensional stability through rapid freeze cycles. Stack 6-8 high without bottom box crushing \u2014 maximizing cold storage cube utilization.<\/p>\n<p><strong>Containerized Export Shipping<\/strong>: Multi-week ocean freight from processor to destination port. PP boxes maintain structure through temperature fluctuations, port handling, and customs inspection. Optional insulation inserts match performance to transit duration.<\/p>\n<p><strong>Air Freight<\/strong>: Lightweight construction reduces air freight costs vs EPS (which ships rigid, wasting cargo volume). PP boxes fold flat for return logistics.<\/p>\n<p><strong>Wholesale &amp; Distribution<\/strong>: At destination, boxes can be color-coded by species, grade, or customer.
