Here is an interesting topic related to aluminum cans, which we use frequently. Do Aluminum cans have a plastic liner inside of them? Yes, this is a general question among the community, and the simple and short answer is “Yes,” it does. Let us learn about the background and theory behind plastic lingered aluminum cans and how they can impact the environment directly and indirectly.

Do Aluminum cans have a plastic liners?

Aluminum cans are the best for various beverage packaging options, which have been used more often in the last century. There are many specialties with Aluminum compared to other beverage packing methods like glasses and plastics. They are simple to put together, resistant to breaking and are not heavy an excessive amount. Another usage is the multiple time can be used and may also be recycled the cans without destroying it. 

But there is another risk associated with metal like Aluminum as it is a flammable metal that has the potential to react and combine with the can’s content. For example, if they can contain acidic liquid media, the Aluminum reacts with the content and decade or makes another component as a result. 

This chemical risk is the primary situation in that plastic came into the act. 

What is the reason behind plastic liners in Metal cans?

The plastic liner is made by wrapping a thin layer of plastic around the inside of the metal can. It keeps the food in the can from contacting the metal. The plastic layer prevents the metal from mixing with the food in the can, which could make the food taste rusty or even rust the can.

Plastic liner manufacturing

Polyethylene terephthalate (PET) is the type of material used to make the sleeve made of plastic. PET is a durable plastic that is also very lightweight and can be recycled several times. When the can is manufactured, the PET plastic liner is attached to the inside.

The can is cleaned after it has been used. After that, an electric charge is applied to the PET plastic cover so that it may be sprayed into the inside of the can. Next, the can is heated to fix the plastic, creating a close link between the plastic and the metal. Finally, the can is cooled and ready for use.

Are Plastic Liners Bad for the Environment?

Here is the problem emerging point. Yes, the short answer for plastic liners in Aluminum can be bad for the environment, not in the short term but definetly in the long term. As we identified, plastic liners are required to keep metal from combining with the can’s contents. However, these liners negatively affect the environment directly and indirectly. 

Plastic material degradability?

It’s because you can recover PET plastic, but it takes thousands of years to break down on the earth. That means the biodegradability is slow for plastics.

If plastic bags aren’t thrown away correctly, they could end up in dumps or the ocean, where they could stay for hundreds of years before breaking down. Plastic lids can also end up in the recycling process, which makes it harder to bring back metal cans.

However, many locations that recycle can also have the capacity to process cans that have plastic bottoms. During the disposal process, the plastic liner attached to the metal will be separated so that both components may be retrieved independently. Coverings composed of materials that can be quickly recovered or degraded over time are also being developed by several firms as part of their product lineups.

End Note:

Usually, plastic is used to line aluminum cans to prevent the metal from contacting with the can’s contents, especially for food or drink. How interesting is that! So, they can have a liner made of PET plastic, which protects the contents from damage while it is being manufactured. 

As you know, recovering plastic from plastic bags is possible, and many recycling facilities are set up. This is uplifting information for the planet. As consumers, we can make a difference by supporting businesses working toward developing packaging materials that are less harmful to the environment and by appropriately returning our metal cans. Therefore, we do not need to be considered the plastic liners in Aluminum cans make a harmful impact on the environment unless we dispose of and recycle the materials at the correct way
