Shenzhen Oneier Technology Co., Ltd is a cooler bag manufacturer producing neoprene insulated coolers for brand owners, retailers, and promotional buyers. We combine OEM/ODM manufacturing with wholesale supply, so you can source stock-style coolers or develop a fully custom line. Our factory runs 10+ production lines with 500+ workers and a capacity of 5,000 pcs/day (2022 figure). Manufacturing experience dates to 2007, with the company registered in 2016.
Neoprene is our hero material for cooler bags. It is soft, flexible, and machine-friendly for printing, which makes it a strong choice for brands that need a custom look without a heavy hard-shell construction.
Product types
Our cooler bag range covers the most-requested formats for retail, e-commerce, and promotional programs:
- Neoprene cooler bag — the core insulated bag for lunch, picnic, and beach use
- Bottle insulator — neoprene sleeve for single bottles and drinks
- Can coozy — neoprene can holder for events and branding
- Neoprene laptop sleeve, 11–15.6" — for buyers building a matching neoprene accessory line

Reference price ranges run from $0.15–$4.59 for coolers, coozies, and bottle insulators, depending on size and material. MOQ is confirmed per specification and customization in your quote.
Insulation construction
A cooler bag only performs if the thermal layer is built correctly. We work with neoprene as the primary insulation material, plus Polyester, Oxford, Nylon, PVC, PU, Cotton-Canvas, EVA, and TPU for outer shells, linings, and trim. Construction is adapted to the item:
- Neoprene body for flexibility and close fit around contents
- Insulated lining options for lunch, picnic, and beach coolers
- Zipper and seam placement set for daily use and repeated opening
- Waterproof dry bag construction for wet environments
Neoprene thickness, lining choice, and outer fabric all affect how long a bag holds temperature. Buyers usually tell us the target use case and we match the build to it. Strap style, zipper type, compartment layout, and sizing are confirmed per project — tell us your required configuration and we will match the build to your brief.
