Insulated bags refer to thermally insulated shipping containers designed in the form of a bag. They are light thus can easily be carried with thermally insulated contents inside. However, its weight depends on the exact contents they carry. They are usually designed using thermally insulating materials. Insulated bags are intended to maintain the temperature of the items it carries. If the items are warm, this bag helps to maintain their warmth. If the items are cold, it maintains them in a warm state. In most cases, however, the printed bags are used to maintain items that require low-temperature levels to prevent them from gaining heat and getting spoilt. Insulated bags are sometimes referred to as thermal bags. They are used in different industries such as food and beverage industry as well as pharmaceutical industry. Below is a brief discussion of how insulated bags are used in different industries to achieve the goal of optimal temperature maintenance.

In most cases, insulated bags are used for transporting different types of food and food products.


Most of these bags are specially tailored and designed to carry and transport chilled and frozen food. Ideally, they are meant to be used by retailers such as fishmongers, butchers, farm shops, delicatessens among other food retailers. They are suitable for maintaining foods in a chilled state from the time of their purchase to the time they arrive at home or the time they become ready for use. To realize maximum effect, they are at times used together with chilled packaging coolants.

Apart from transporting food products, insulated bags are also used to carry medicines and drugs in the required state of temperature. By transporting temperature-sensitive drugs, these bags protect medicinal drugs from adverse temperatures, excess light, and shocks. This purpose is mostly important while transporting and storing vaccines which are very delicate biological/organic substances that are highly vulnerable to loss of partial or complete effectiveness if exposed to adverse environmental hazards such as excess heat and bright light. Typically, pharmacists and doctors recommend that such vaccines should be kept at specified temperature range usually between 2 to 8 degrees C from the time of manufacture to the time of use.


These bags, therefore, offer a significant solution to the common problems associated with exposure to medicinal drugs to adverse environmental conditions. According to the recent reports released by the World Health Organization, 7% of all temperature-sensitive medicinal products undergo a certain level of degradation in potency during their transit.


Other than pharmaceuticals and food industries, another important area where the role of insulated bags is of paramount importance is drinks and beverage industry. Most dealers of drinks and beverages that require extremely low temperature such as yogurt and other milk products in liquid form as well as other refrigerated drinks benefit from the use of insulated bags by helping them to maintain their drinks cool during transportation and short term storage. They also serve an instrumental role in maintaining the state of other drinks such as fruit juices and carbonated drinks.

In a nutshell, insulated bags are important in maintaining the temperature of items and products that are potentially vulnerable to destruction upon exposure to the adversity in the environment. They are widely utilized in areas like food storage, medicine and vaccine maintenance, maintenance of drinks and beverage in the right temperature among other uses.
