Food storage containers

Food containers were created to store food and drinks for later transportation. Thus, the history of packaging follows the history of logistics and food transportation.

 

In ancient times, people did not have to worry about packing food. They would simply consume what they hunted or harvested locally. During the prehistoric period, many nomadic tribes would travel for food and water, often depleting these resources in their place of origin.

 

With the rise of sedentary lifestyles, food and drinks need packaging for storage and transportation.

 

The first types of food containers were made from 100% organic raw materials available in nature. Bark, leaves, and other natural materials were used for packing and transporting food.

Throughout history, humans have used various materials to create packaging, including glass, cans, paper, and Plastic.

 

Next, we will discuss the characteristics, similarities, and differences between glass and plastic containers.

Plastic containers

Until recently, plastic containers were trendy. They won the preference of families for being cheap and light. Families used plastic containers for everything, like heating food in microwaves and keeping their soups hot.

 

Recently, concerns have been raised about the negative impact of plastic on human health and the environment.

 

Aware of the plastic container issues, Toronto University warns their students: "Plastic is the easiest, cheapest option for food storage, but not always the smartest. While plastic containers are great for cold storage, traveling around, or for bringing food to things like potlucks (so you can leave it behind), when it comes to storing hot food and using to re-heat last night's dinner, you want to steer clear."

 

There are different types of plastic. As Earth 911 explains, "Two types of plasticizers, which are substances added to plastic to help stabilize and shape it, are of concern to human health: bisphenol-A (BPA) and phthalates. These substances are believed to be "endocrine disrupters," which means they mimic human hormones and can cause chronic health risks. These can leach into the food or beverage from the plastic when it's heated. There is also evidence that some acidic foods can cause leaching without being heated."

 

It's essential to be aware that while convenient and affordable, plastic containers can pose health risks due to the chemicals used in manufacturing. This is especially true when you store hot food that has just come out of the oven or stove in them, as well as when you heat up hot food in these containers in the microwave. It's best to be cautious with your use of plastic containers to ensure your health and safety.

Another problem with plastic containers is their low durability. Over time, they lose their colours and become old and worn.

 

There is also a significant issue with the low recycling rate of plastic, which harms the environment.

 

Due to these issues, some consumers have opted for alternative solutions. One such solution is to return to using glass containers. Learn more below.

Glass containers are the oldest packaging material humans have used, after wood and other organic materials. Before glass containers, humans stored their food in tree bark and leaves.

Commercial glass is produced through a mixture of sand, recycled glass, soda ash, and limestone.

 

Glass is a non-porous material that prevents the accumulation of dirt and bacteria susceptible to other materials. Glass containers are practical and straightforward to clean.

 

Glass containers are an excellent choice for those who want to reduce waste. They are durable and can be reused for many years. Simply wash them well, and they will look as good as new. This is one of the most significant advantages of glass containers, as they can be reused as often as you want.

 

If you avoid thermal shock, glass containers can be used to store both hot and cold food. Unlike plastic containers, glass can withstand high temperatures, making them suitable for oven and stove use.
