Fresh-food cold-chain losses too high? SuperCooler foldable soft cooler holds -18°C for 24 hours and tackles the last-mile freshness and cost problem

A lychee gets picked, then the real survival game starts. From farm to customer, China loses 20% to 30% of fruit and vegetables after harvest. Broken last-mile cold chains and weak insulation are a big part of the problem.

Why traditional insulation keeps dropping the ball

For years, fresh-food cold chains have leaned on foam boxes and basic insulated packaging. The pain points are pretty obvious:

• Heavy and slow — annoying to carry, slow to turn around;

• Space hog — empty-box returns eat up truck space and keep freight costs high;

• Weak hold time — ordinary materials conduct too much heat. In summer, outdoor delivery can struggle to last even half a day, so frozen goods soften and produce wilts.

That hits twice: profit gets eaten, and the brand takes the blame.

So how does Super Tech Cold Chain keep the chain from breaking?

Traditional foam boxes are still fighting the same three problems: too heavy, too bulky, too short on hold time.

Super Tech Cold Chain’s foldable soft cooler answers with four basics that matter: -18~60°C coverage, 12~24h temperature control, a foldable space-saving build, and tough wear resistance. A solid fit for fresh fruit, frozen foods, and prepared meals.

1. VIP vacuum insulation inside

Inside is a vacuum insulation panel (VIP) layer with thermal conductivity as low as 0.002W/(m·K)—just 1/10 of conventional insulation. Insulation performance is 4-6 times conventional polyurethane.

Deep freeze at -18°C? Hot-chain transport at 60°C? It can handle both, with 12 to 24 hours of temperature control to keep fruit fresh and frozen goods frozen.

2. Tough Oxford-fabric shell

The SuperCooler foldable soft cooler uses high-strength Oxford fabric that can take repeated loading, long bumpy trips, washing, and everyday abuse. Less wear means fewer replacements and lower consumable costs.

3. Fold it down when you’re done

When it’s empty, just fold it up. Easier returns, less weight, less warehouse space wasted.

4. One bag, loads of cold-chain jobs

Fresh fruit, deep-frozen delivery, community group-buying last mile, direct-from-origin shipping, supermarket replenishment—it’s built to cover the full fresh-food cold-chain mix.

SuperCooler foldable soft cooler: lock in the cold, keep the value

In fresh-food logistics, temperature is the competition.

From the branch to the table, every kilometer and every temperature swing can hit quality—and trust.

SuperCooler combines vacuum insulation + foldable design + long-duration temperature control to tackle the last-mile temperature problem.

Fresh fruit stays fresh, frozen goods stay frozen, hot-chain loads stay on temp—all with a lighter, space-saving setup that makes cold-chain transport easier and more efficient.

Backed by parent company Super Tech’s vacuum-insulation tech, Super Tech Cold Chain keeps every degree under control, every step of the way.
