First thing foremost, you must invest in a good, tight sealed, vacuumed, insulated heavy duty food container. This will become economical rather than spending few hundreds on colorful, non-BPA free plastic containers that will easily spoil and leak the food you have prepared for your children.
The Anatomy
The Engineering
There are so many trusted brands in the market like:
1. Tiger
2. Thermos/ Foogo
3. Zojirushi
You can try experimenting at home using a plastic FOOD container and a Vacuum Insulated Container by filling it up with your lunch (rice and viand in a separate containers). Make sure that you will prepare this ahead of time and consuming it about 6 hours after.
Investing on these high grade engineered food containers will end up seeing those Happy Faces on your children when reaching home. They will bring back their lunch boxes squeaky clean!
FRIENDLY ADVICE:
Refrain from shopping too much. Avoid purchasing those cute Plastic Containers with their favorite characters printed on it! I have been through that, and disposing these plastic containers aren't easy as well.
Being impulsive is not a solution on how you will convince your children to consume their baon in school. You will just end up stacking up these containers....
Note: Thanks to Google for these wonderful Photos!
