The bottom line: these 1.5 in thick paper-based liners are best for businesses shipping frozen food, meat, fish or perishables in 12 in x 12 in x 12 in boxes who want a plastic-free insulating option that absorbs condensation. The most compelling reason to consider them is the multilayer cellulose wadding inside a 40# kraft paper shell that claims to keep products cold up to 72 hours when used with ice packs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness and retention:\u003c\/strong\u003e The 1.5 in thick liners provide substantial thermal mass and, combined with ice packs, are designed to keep shipments cold for up to 72 hours.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePaper-based construction:\u003c\/strong\u003e A 40# kraft paper shell and multilayer cellulose wadding offer a fully sustainable, plastic-free solution that avoids off-odors or toxins.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondensation control:\u003c\/strong\u003e The natural cellulose interior absorbs condensation to help keep frozen and refrigerated goods dry and reduce microbial risk from pooled moisture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity per box:\u003c\/strong\u003e Each liner pair fits a 12 in x 12 in x 12 in box and creates roughly 3.6 gallons (9 in x 9 in x 9 in) of usable internal volume for packed product and coolant.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance vs alternatives:\u003c\/strong\u003e The EcoMax thermal-paper liners are positioned to outperform PET and plastic bubble foil, retaining cold for several hours longer in transit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe EcoMax liners are aimed at small food producers, meal-kit companies, specialty seafood or meat shippers, and anyone who needs a plastic-free insulating option for 12 in shipping boxes.
