25mm PE foam insulated cooler bag bulk
For B2B buyers sourcing Cooler Bags, Delivery Bags, and food delivery bag solutions in bulk, thermal performance is the critical specification. Xiamen Obaili Manufacturing Ltd. specializes in insulated delivery bags and cooler backpack products featuring 25mm PE foam insulation—the industry benchmark for extended ice retention. Here is why we are the factory for your bulk order.
Why 25mm PE Foam Matters for Bulk Cooler Bags
PE (polyethylene) foam is the preferred insulation material for high-performance insulated delivery bags. Its closed-cell structure provides water resistance, moisture-proofing, shockproofing, and excellent thermal insulation properties . The 25mm thickness delivers optimal cold retention for food delivery bag applications requiring 8+ hours of temperature stability.
Obaili implements strict quality protocols for PE foam insulation. Because EPE (Expandable Polyethylene) foam has inherent elasticity, our cutting department carefully controls layer counts and process parameters to minimize dimensional errors . This precision is essential for cooler backpack and Delivery Bags requiring consistent performance across bulk production runs.

Proven 25mm PE Foam Performance
Obaili has delivered 25mm PE foam cooler backpack and food delivery bag solutions with documented results. In one case, our Oxford fabric cooler bags demonstrated ice not completely melting in 18 hours, with 24-hour zero-leak testing at 0°C ice water . The food-grade aluminum foil inner liner, combined with 25mm PE foam, achieves cooling endurance exceeding customer requirements by up to 2 hours .
For a U.S. outdoor lifestyle retailer, Obaili provided insulated delivery bags with 12+ hour thermal performance. Over three years, the client's market share grew from 12% to 23%, and product return rates dropped below 0.8%—far below the 3% industry average
