Lunch Bag Insulation R-Value Guide for Wholesale Buyers
Published: August 23, 2026 | 8 min read
Insulated lunch bags and cooler bags vary hugely in cold-retention. The R-value (insulation rating) and food-safe liner are the two specs that matter. Common constructions: 6mm EPE foam + PEVA (R=0.18, 2-4 hr cold), 8mm PEVA + foil (R=0.25, 4-6 hr), 10mm foil-lined closed-cell foam (R=0.40, 6-8 hr). Food-safe liners must be BPA-free PEVA or food-grade aluminum. Below is the buyer spec matrix.
