How to Choose a Thermo Insulated Box

1. Material :

Good boxes generally produced by food-grade environmentally friendly LLDPE materials, which are non-toxic, odorless, anti-ultraviolet, and are not easy to change color. Plastics have been widely used in various fields of daily life. Plastic products such as plastic bags, plastic cups, and plastic bottles can be seen everywhere. However, the materials used in some plastic products on the market may release toxic and harmful substances (even some carcinogens) under different conditions such as temperature and humidity, which is unsafe.

2. Tightness:

This is the primary consideration when choosing a thermo insulated box. Although products of different brands have different sealing methods, good sealing is a necessary condition for long-term storage of memory food.

3. Heat and cold resistance:

The insulated box should have higher requirements for heat and cold resistance. They will not deform in high temperature water and can even be disinfected with boiling water.

4. Durable:

It has excellent impact resistance, is not easy to break under heavy pressure or impact, does not leave scratches, and can be used for life.

5. Fresh:

The international sealing measurement standard was evaluated through the moisture permeability test. High-quality insulated box have 200 times lower moisture permeability than similar products, which can keep food fresh for a long time.
