1. 12V Silicone Rubber Heater for Bag with Integrated Thermostat
Hongtai manufactures rugged 12V silicone rubber heater for bag inserts, designed specifically for the commercial food delivery industry. Unlike standard industrial heaters, these are reinforced flexible silicone heating blanket systems engineered to withstand the constant flexing, insertion, and removal associated with daily pizza and catering logistics.
Featuring a 12V silicone heating pad with thermostat integration, these units automatically regulate temperature to keep food in the “Safe Zone” (above 60°C/140°F). This ensures the Pizza Hot Food Delivery Bag Heating Element maintains food quality without overheating the fabric bag or draining the delivery vehicle’s battery excessively.
2. Key Technical Features
-
Smart Temperature Control: The Pizza Hot Food Delivery Bag Heating Element Silicone Heater Pad 12V w/ Built-in Thermostat cycles power automatically (typically ON at 55°C, OFF at 70°C) to conserve energy.
-
Mechanical Flexibility: Multi-strand resistance wire construction allows the fleixble silicone heater to bend and flex without breaking the internal circuit.
-
Sanitary Design: The non-porous silicone surface is moisture-resistant and easy to wipe clean, meeting food safety hygiene standards.
-
Automotive Compatibility: Designed for 12V DC power sources, compatible with car cigarette lighters or portable lithium battery packs.
-
Overheat Safety: Integrated thermal protection prevents fire hazards, safe for use inside polyester or nylon delivery bags.

4. Applications in Food Logistics
This heating element pad is the core component for:
-
Pizza Delivery Chains: Ensuring the “Hot & Fresh” promise is kept during the last-mile delivery.
-
Catering Logistics: Holding warm pans during transport to events.
-
Meals on Wheels: Keeping food safe for elderly care delivery.
-
Battery Heated Clothing: Modified versions can be used for wearable heating applications.
5. The Hongtai Difference: Durability
Rigid heating elements cannot survive inside a soft delivery bag. Hongtai uses a specialized “floating” wire design within the custom silicone heating pad. This allows the internal wire to move slightly as the bag is crunched or folded, preventing the catastrophic failures common in cheaper etched-foil bag heaters.
6. FAQ
Q: Can I wash the delivery bag with the heater inside?
A: The flexible silicone heater surface is waterproof, but the connector and thermostat area are vulnerable to submersion. We recommend removing the heater before machine washing the bag, or simply wiping the heater clean with a damp sanitizer cloth.
Q: How long will a portable battery last?
A: A 60W heater draws about 5 Amps. On a standard 20Ah battery, it would theoretically last 4 hours. However, because the built-in thermostat cycles the power off when hot, real-world runtime is often extended by 30-50%.
Q: Can you customize the size?
A: Yes, we are an OEM factory. We can manufacture any size of flexible silicone heating blanket to fit your specific insulated bag dimensions.
