How to make an insulated bag to keep food warm longer

While reusable thermal bag are great for keeping food warm for several hours, you can actually keep food warm in the bag for longer in a few simple steps.

1. Wrap food in extra foil

The foil in the insulated bag will reflect back quite a bit of thermal energy, trapping it in the bag and keeping your food warm.

2. Wrap in paper towel

Paper is actually a very good insulator that you can use to enhance the insulation properties of your thermal bag. Heat the food, then wrap it in a paper towel before placing it in an reusable thermal bag for food. Paper towels both insulate food and absorb moisture, preventing it from drying out. Like how people use paper towels in the microwave to keep food from drying out.

3. The small instant hot pack can be a great little pack to add to your reusable thermal bag for food. You can get disposable or reusable ones. I prefer reusable ones, they are plastic (not paper) and you can use them multiple times. Activate the thermal pack, then wrap it in aluminum foil and place it in the thermal pack with the food.

Printing process of thermal insulation bag:

Non-woven thermal insulation bags usually use the screen printing process, which is also called screen printing, and is also a printing process often used by many manufacturers. Many of them are manually printed. Let me explain to you the more popular printing processes in the non-woven bag market!

1. Watermark

Non-woven thermal insulation bags are famous for having water-based elastic glue as a printing medium, which is also common in textile printing, commonly known as printing. When printing, the color paste and water-based elastic glue are also mixed. No chemical solvent is needed when printing, and it can be washed directly with water. The characteristics of non-woven thermal insulation bags are good coloring, strong covering performance and fastness, washing resistance, and basically no taste.

2. Gravure printing

This process is divided into two parts for production. The non-woven insulation bag first uses the traditional gravure printing process to print the graphic on the film, and then uses the lamination process to laminate the patterned film on the non-woven fabric. on the cloth. This process is usually used for large-area pattern-printed non-woven thermal insulation bags. The characteristic of this process is that the printing is very convenient, the whole process is produced by the machine, and the production cycle is also very short. In addition, because the non-woven thermal insulation bag has good waterproof performance, the durability of the finished product is much better than that of the non-woven thermal insulation bag produced by other processes. Films are available in gloss and matt options, with matte having a frosted effect. This kind of craftsmanship is fashionable, durable, full of color, and the pattern produced is very real.
