Yiduo’s Rubber Hot Water-filling Bags are crafted from top-grade anti-aging rubber, ensuring durability far beyond traditional hot water bags. Our advanced manufacturing process guarantees superior heat retention, leak-proof performance, and explosion resistance, making them a reliable choice for therapeutic use. Designed with a wide nozzle for easy filling and safe handling, these bags are perfect for soothing muscle pain, menstrual cramps, arthritis, or simply keeping warm during chilly nights.
As a trusted manufacturer since 2008, Ningbo Yiduo Plastic Products Co., Ltd. combines innovation with quality control to deliver customizable solutions. We offer OEM/ODM services, allowing you to personalize size (15.8×10.5cm to 9.5×24cm), color (off-white, pink, gray, blue, or custom), and branding. Our bags undergo 185°C high-pressure molding for seamless construction, while the soft, flexible material adapts comfortably to body contours. Eco-conscious and skin-friendly, Yiduo’s products meet international standards for both home and professional use.
These multifunctional hot water bags serve as effective heat therapy tools for diverse needs. The gentle warmth (recommended 2/3 filling capacity: 340ml/525ml) alleviates back/neck strain, sports injuries, and joint inflammation while promoting muscle relaxation. Unlike rigid alternatives, the pliable rubber conforms to body curves for targeted relief – place it under shoulders during desk work or wrap around knees for arthritis comfort. During winter, they double as bed warmers; simply fill with warm (not boiling) water for 6-8 hours of cozy heat. For cold therapy, the same bag can hold ice water to reduce swelling post-injury.
Engineered for convenience, the wide-mouth design prevents spills during filling/draining, while the integrated sealing technology eliminates weak seams. The smooth surface resists bacterial buildup and wipes clean easily – ideal for office, travel, or home use. Parents should supervise children and avoid boiling water (50-60°C recommended). Available in compact (15.8×10.5cm) and elongated (9.5×24cm) sizes, these bags fit discreetly in luggage or work bags. The material remains flexible even in cold environments, unlike brittle PVC alternatives.
