How to choose a lunch box cooler packs?

When buying a cooler bag, you need to pay careful attention to some of the most important points:

  1. weight and volume of the cooler.
  2. material from which the cooler is made.

When choosing the lunch box cooler packs, it is necessary to determine how it will be delivered to the picnic site or to the country site. After all, the volume of an automobile cooler is approximately 50 liters, that is, it will be very difficult to transfer it from place to place.

In addition, it must be remembered that the larger the volume of the cooler, the more installed the cold storage batteries, therefore, the longer the product can be stored in it.

Most often for the production of coolers, strong synthetic fabrics are used, which have water-repellent properties and do not penetrate ultraviolet rays.

The material for the outer part of the coolers is often nylon, polyester or polyvinyl chloride (PVC). These types of fabrics are very easy to clean from any contaminants and quickly dry. The stability of the bag provides a thermal insulation in the form of a special foam, which is laid between the top of the bag and its inner container.

When buying a cooler, you should always pay attention to its interior. This is where food and cold stores will be located.

It happens that manufacturers try to save on the inside of the bag, laying in it not high-quality PVC material with reflective properties, but simply strong polyethylene of different colors.
Naturally, in such a bag, the products will lose their freshness much faster. Store products in such a product for a maximum of three hours, even with a full set of cold storage.

Automobile coolers, as a rule, is made of three layers:

  • external, made of plastic, light colors;
  • the inner container in which the products are placed;
  • foam polyurethane layer between them, the thickness of which is 3-5 cm.

This design allows you to keep the freshness of the products for about 12 hours without the use of cold storage batteries, if you complete the container with batteries, the products will remain fresh for more than 24 hours.
