Microwave Heating Reusable Hand Warmers Lunch Box Heat Packs

Jisi Cold Chain Technology focus on the development and production of heat and cold storage box.This is the hot water heating heat storage box,After more than 2 years of improved formula and test, energy storage box in the 80-90 degrees hot water and heat for 10 minutes, temperature can reach 70-80 degrees, if do not need the temperature is too high, can reduce the heating time.In the thermal bags can be maintained at 50 degrees temperature 6-8 hours.

Characteristic:

1,Heat capacity is big: after many improved formula of the heat storage material, the greatest degree of play the function of heat accumulation, increase the heat storage.

2,Release time is long:inthe thermal bags keep warm 6-8 hours.Most of the time to maintain constant temperature 50 to 55 degrees.

3,Increasing the safety factor of the product:the shell is resistant to high food grade PP, don't melt or deformation at high temperature , can be used repeatedly.

Instructions For Heat Pack Products

This is a storage pack that needs heating,The inner material of this product is solid at room temperature,It needs to be heated by microwave oven or boiled water, and the heat storage material inside should be melted completely as far as possible, so as to absorb heat to the maximum extent and making the heat preservation time longer.

Matters needing attention for microwave heating:

1. Set the microwave on medium to high heat, not more than 5 minutes.In the process of heating, if you find the plastic box drum phenomenon, please immediately stop heating, to avoid the plastic box rupture, polluting the microwave furnace.(Note : About 3 minutes is appropriate, you know the temperature of the microwave oven is very high, the box will melt and burst over time.)

2. To avoid burns, bring gloves when you remove them from the microwave (Because the temperature about 70-80 degrees)

3. After removing from the microwave, check whether the internal material has completely melted. If not, please continue to heat for 30 seconds at a time.When the heat storage material is completely melted, it can be put into an insulated bag or insulated cooler box with food that needs to be insulated.

Matters needing attention for boiling water heating:

Put the product into hot water(more than 60 ℃ hot wate). After 10 minutes, check whether the internal heat storage material has completely melted. When all melted, take it out, it can be put into an insulated bag or insulated cooler box with food that needs to be insulated.

The range of application:

Applicable to school, work to carry lunch, outdoor activities, tourism, take-out lunch need to keep the temperature field. Add a layer of flannel, can used for heating in winter.
