VIBB Fresh Bag: Demonstration, Design, Performance and Real-World Applications

VIBB Fresh Bag: Demonstration, Design, Performance and Applications

Why we manufactured Vacuum Insulated Fresh Bag?

Most cooler bags are foam and fabric; they help for an hour or two, then give up. The VIBB Fresh Bag (Sanyou London) applies vacuum-insulation panel (VIP) technology in a lightweight, everyday carrier—so cold stays cold for a working shift, a long errand, or a day outdoors, without electricity.

Performance—stated plainly

Hot-day test: at +35 °C ambient, with contents pre-chilled to 2 °C:
- With a rolling cart workflow (frequent open/close): the bag kept the internal temperature below 10 °C for about 5 hours.
- With a small refrigerant/PCM pack and disciplined openings: up to 6.5 hours below 10 °C.
This is passive cooling; no plugs, fans or dry ice. Duration in your routine depends on load mass, start temperature, opening frequency and packing tightness.

Design that makes the difference

Thermal core: ultra-thin flexible VIP panels with exceptionally low thermal conductivity, arranged in a quilted architecture to minimise edge losses.
Shell and liner: tough, wipe-clean outer with a smooth food-safe inner; seams sealed for quick sanitation.
Closure: full-length zip with storm flap to reduce warm air ingress during quick access.
PCM sleeve: discreet pocket sized for our phase-change packs when routes or heat waves demand longer hold times.
Carriage: adjustable shoulder strap plus grab handles; optional rack clips for bikes and e-scooters; D-rings for robot mounts.
Proofing: integrated data-logger pocket at mid-load height; tamper-evident loop points; clear window for order tickets.
Sizes: a family of volumes—from compact totes for personal errands to courier-grade bags for multi-drop shifts. All are light, rigid enough to protect the load, and easy to stow.

A simple demonstration you can run tomorrow

Show your team—or yourself—what the bag does in the real world.

Set-up (home or depot):

Chill a mix of groceries or meal packs to 2–4 °C.
Place a small PCM pack conditioned to the same band in the sleeve (optional for the 6.5-hour profile).
Drop a data logger or probe thermometer into the built-in pocket.
Stage the test space near a sunny window or a warm room (aim for ≥30 °C if possible).
Run two bags side-by-side: VIBB Fresh Bag vs an ordinary foam cooler, opening both once per hour for 30 seconds to simulate deliveries.

What to expect: the conventional cooler will trend upward quickly; the VIBB trace will rise slowly and steadily, staying under 10 °C far longer, with smaller spikes after each opening.

Applications beyond the obvious

Delivery fleets—riders, drivers and micro-mobility

Problem: time between store and doorstep varies; hot pavements and idling traffic warm loads.
Fresh Bag fit: steadier temperatures mean fewer “too warm/too melted” complaints; fewer refunds; better ratings. Rack clips and robot mounts make integration simple.

Autonomous delivery robots

Problem: small cargo bays, no active cooling.
Fresh Bag fit: sized inserts create a passive cold pod inside the robot; logger pocket provides verifiable traces for QA.

Everyday living—errands and leisure

Gym-then-grocery: keep dairy and meat cold in the car park and on the drive home.
Picnic days: fewer ice-pack hassles; more room for food; easy clean-down.
Hiking and hilltops: pack chilled snacks—and, with a high-temp PCM, carry warm food to enjoy at the summit.

Corporate and campus hospitality

Problem: last-metre carry from kitchen to meeting rooms; long walks across sites.
Fresh Bag fit: quiet, power-free holds for fruit, desserts or boxed lunches—no trolleys, no plug-ins.

Pack-out that protects performance

Pre-condition: chill the payload properly; a bag can’t fix warm contents.
Load tight: remove voids with dividers; air is the enemy in a cold bag.
Open with purpose: plan picks so the zip is open for seconds, not minutes.
Use the PCM sleeve on hot days or long routes; condition packs to the printed set-point.
Log the first week: a cheap data logger builds confidence and trains good habits.

Hygiene, durability and sustainability

Clean-down: smooth liner wipes with neutral detergents; seams are sealed; dries fast.
Service life: replaceable straps and zipper pulls; serial numbers for asset tracking.
Waste cut: reusable VIP construction displaces mountains of single-use EPS; fewer spoiled orders reduce food waste and refunds.

Frequently asked (straight answers)

Can it keep food hot?
Yes—swap in high-temperature PCM packs. The same VIP shell slows heat loss; you set the service temperature according to your food-safety plan.

Will it fit our bike racks or car boots?
We supply sizes for common racks and courier boxes; custom brackets are available. For cars, the flat base and compact height fit under parcel shelves.

Is it heavy?
No. VIP gives high resistance without bulky foam; you carry payload, not packaging.

What about rain?
The shell resists showers; for sustained rain, add the optional rain cover.

Choosing the right Fresh Bag

Rider model: slimmer profile; quick-grab top; optimised for frequent access.
Courier model: larger volume; reinforced base; ticket window and logger pocket as standard.
Adventure model: extra strap points; optional hot-food PCM kit; external bottle holster.

Our team can map bag sizes to your order volumes, rack types, and route lengths.
