Description
The short answer for sourcing teams: the JUNYUAN 30L waterproof backpack cooler is a leakproof, heavy-duty insulated cooler pack for beach, camping, picnic and tailgating brands — 600D PVC exterior with a watertight zipper, triple-layer foam holding contents below 4 °C for 24+ hours, custom branded and produced to AQL 2.5 in our SGS-audited Quanzhou factory. OEM/ODM orders start at a MOQ of 500 pieces with 30% T/T deposit, samples in 6–10 days and bulk production in 35–50 days.
Insulated cooler-pack demand is driven by the same outdoor-recreation growth that raised cooler and hydration-equipment sales worldwide (Grand View Research tracks the global cooler market expanding with outdoor leisure). For brands, the decision comes down to three controllable specifications — ice retention time, leakproof sealing and bulk pricing — all of which our factory pins to written test standards before tooling starts.
30L Waterproof Backpack Cooler — Insulated & Leakproof

This waterproof backpack cooler carries a 30 L / 30-can main compartment designed for drinks, meals, fruit and ice packs, with a dedicated front zip pocket for dry goods and tableware. A lightweight, breathable back panel reduces condensation on long carries, and the reinforced shoulder straps include a built-in bottle opener.
Large Capacity & Smart Storage

- Main compartment: 30 cans / 30 L, insulated and leakproof for drinks, ice packs and meals.
- Front zip pocket: stores utensils, dry snacks and small accessories.
- Vertical phone pocket: keeps a cellphone or small items within reach.

The bag uses a 600D PVC + PEVA build with a horizontal, watertight zipper and triple-layer closed-cell foam insulation. In factory testing the compartment stays below 4 °C for 24+ hours at ambient heat when packed with ice packs — enough for a full day on the beach, at the trailhead or in the stand.

Frequently Asked Questions
How long does this waterproof backpack cooler keep ice?
With proper ice packs, the triple-layer foam insulation keeps contents below 4 °C (sub-40 °F) for 24+ hours in warm-weather conditions. Retention depends on how full the pack is, ambient temperature and how often it is opened.
Is this cooler bag leakproof and fully waterproof?
The bag is leakproof: the 600D PVC body and watertight horizontal zipper keep condensation and melted ice from leaking out. It is designed as a temperature-retention cooler pack, not a submersion dry bag, so we recommend against submerging it.
Can I put a custom logo on the cooler backpack?
Yes. Screen printing, heat-transfer, rubber/TPU and woven-label logos are available on a MOQ of 500 pieces per design, with pre-production samples in 6–10 days.
What fits inside the 30 L cooler bag?
About 30 standard cans plus ice packs, or meals, fruit, snacks, bottles and tableware. Two mesh side pockets hold wine or water bottles.
What are the MOQ and lead time?
OEM/ODM orders start at MOQ 500 pieces with 30% T/T deposit. Custom samples ship in 6–10 days after artwork approval; bulk production takes 35–50 days, followed by final quality inspection to AQL 2.5.
