Does Gas Eat Through Plastic? Will Plastic Melt?

Did you know gas can dissolve a wide range of plastics, causing a substantial amount of spillage? When gas is exposed to sparks, it could unfortunately start a fire. According to top-notch officials, you must always use a container approved by the transportation department to handle flammable fuels. For further information on the subject, please check out the rest of the discussion now.

Does gas eat through plastic? Will plastic melt?

Will gas eat through plastic? A large number of individuals have this particular query. Well, gas can eat through or melt a few plastics such as plastic cans and bags. HDPE or high-density polyethylene is however gas resistant. In other words, it would not be affected by the corrosion of gas and stay intact.

Studies have shown that gas melts plastics only because both of them have similar chemical structure. Plastic and gas are hydrocarbons. This is why gas can interact with plastic’s chemical as well as structural compounds in a seamless manner.

Plastics with powerful chemical bonds, immense durability, and high melting temperature can easily be able to endure gas and other flammable fuels. Gas can never eat through such plastics.

Can gasoline melt plastic?

Yes, gasoline can melt plastic. But does gasoline dissolve plastic? Studies have shown that gasoline never dissolves plastic. The two can react if they come into contact with one another. If you use gasoline to clean oil spills then gasoline would not dissolve anything.

If you unintentionally put gasoline into a container made from plastic, it is possible that gasoline would dissolve plastic. One of the chemical compounds utilized by most plastics is polyethylene terephthalate. It successfully reacts with mineral oil, gasoline, and other such hydrocarbons.

How fast can gasoline melt plastic?

Will gas melt plastic? You have already found out the answer to this question. But how fast does gas or gasoline melt plastic? Gasoline can interact with the molecules present in the plastic quite quickly. So, it would take only ten minutes to melt plastics, provided the plastics have low density.

Which plastic can you use to hold gasoline?

Does gasoline melt plastic? Yes, it does melt certain kinds of plastic, as stated in the previous sections. Now there is another common query – which plastic should you use to hold gasoline. Corrosion resistant, high-density plastics can hold gasoline. These specially made jars and barrels can withstand heat, swelling, deformation, and softening.

HDPE plastics can be used for making jars, barrels, containers, and bottles for preserving gasoline. HDPE or high-density polyethylene has an incredible strength to density ratio. The melting point of these plastics is 130.8 degrees Celsius.

Where can you store gas if you don’t have a gas can?

By now you already know gasoline dissolve plastic. Now it is time to learn about gas storage. If you do not have a plastic barrel, you can opt for a metal container. Keep the below tricks in mind under all circumstances.

  • Pay close attention to the insurance policy and local laws. They will help you understand the gas storage rules in your neighborhood. Gases are extremely combustible and flammable. All cities have decrees controlling their storage. Most allow the homeowners to store a minimum of 2.5 gallons of gas.
  • It is essential to store gas in a jar or barrel that has been approved for gas preservation. Never store gas in your milk jug or glass container . They provide access to sunlight, which degrades gas in no time. Also, these containers are prone to spillage.

To enhance the safety quotient and to retain the shelf life of gas, you should purchase the jerry cans made from plastic. You will get them easily at any hardware store. 

For gasses, it is necessary to maintain a color code.

1. Red – gasoline

2. Blue – kerosene

3. Yellow – diesel

4. Green – oil

You can refer to this color code when your car runs out of gas and you ask your friend for help. If your friend brings a blue jar, you must think twice before filling your car with whatever fuel is in it.

  • Always store gas in a garage or shed that has no connection to your house. Around 2500 fires occur throughout the residences in the United States every year. If you do not wish to be involved in such accidents, please keep your gas away from ignition sources such as a water heater or a furnace.
  • If you do not have a garage or shed, and are forced to store gas inside your home, please adhere to some precautionary measures. Make sure the gas is kept in a cool, well-ventilated space. The space must never get hotter than 70 degrees Fahrenheit and be around 50 feet away from sources of ignition. The gas must also be out of reach of pets and kids.
  • Never fill your barrel to the brim. Gas expands when you heat it up. You must leave some room inside the barrel for this expansion. Most of the barrels have a line up to which you should fill the gas.
  • Invest in a fire extinguisher and keep it near the storage area. If a gas starts a fire, you can put it away without hassle.


In this write-up, you have found out answers to many questions including what plastic can hold gasoline? Let’s address a few more queries that people ask online.

Does gasoline evaporate on plastic?

How long will gas keep in plastic? When stored inside a plastic container, pure gasoline starts degrading and loses its combustibleness due to oxidation and evaporation in just six months.

Can you put gasoline in a blue kerosene container?

You should never put gasoline in a blue container that is designed for kerosene. Kerosene is easier to preserve because it is not as volatile as gasoline. It also does not evaporate or freeze easily. If you put gasoline in a blue container, it will burst and start a fire

Can pet plastic resist gasoline?

PET or polyethylene terephthalate plastic can resist gasoline. It after all has a high melting point, between 250 degrees and 260 degrees Celsius. This is why people have been storing gas in jars made of PET plastic.

Final Thoughts

I hope the above discussion helped you understand the relation between plastic and gas. The next time you are thinking of storing gas in a plastic jar, please refer to all the pointers here. Thank you for reading:)
