Plastic is a versatile material that can be moulded into different shapes and sizes, making it ideal for storing a wide range of chemicals. Its versatility extends to its ability to accommodate the unique properties of individual chemicals. For instance, polypropylene plastic can be used to store corrosive substances, while polyethylene, which was first synthesised in 1898, is now the most common and widely produced plastic globally. It has various applications and can be used to make grocery bags (LDPE), garbage bins and drainpipes (HDPE), and even bulletproof vests (Ultrahigh Molecular Weight PE).
The durability and impact resistance of plastic bottles make them suitable for storing chemicals, especially in high-risk environments or where breakage risks are high. Plastic offers more resistance to breakage than glass, making it a safer option for storing hazardous substances. Additionally, plastic containers can be customised to hold specific chemicals, with polymer tanks built to store a particular weight of fluid. This customisability ensures that each chemical is stored securely, protecting workers and the environment from potential hazards.
The shape of plastic containers also affects their stability and ease of pouring. F-style bottles, for example, have a rectangular shape that makes them easy to store and stack, while their narrow neck and built-in handle facilitate precise pouring. Carafe bottles, on the other hand, are commonly used for acids, solvents, and cleaning products due to their neck finish. The versatility of plastic bottles extends to their sizes as well, ranging from small 8-ounce containers to larger gallon-sized bottles, ensuring that the size is appropriate for the quantity of chemicals stored.
Plastic's mouldability also allows for the creation of pressure vessels, which are specifically designed for gases or liquids under high pressure. These containers are regulated for safety and can withstand the demands of shipping and selling. Similarly, jerricans, made of heavy-duty plastic, are used for storing, transporting, and selling larger quantities of chemicals. Their durability and built-in handles make them ideal for handling hazardous substances.

Plastic is chemically inert and nonporous
Plastic is a versatile material, and its use for storing chemicals is well-established. One of the key reasons for this is that plastic is chemically inert and nonporous. This means that it does not react with the chemicals it comes into contact with and prevents absorption.
The inert nature of plastic is due to the strength of the bonds within its polymer structure. For example, PTFE (Teflon) has strong carbon-fluorine bonds, making it non-reactive to a wide variety of acids and bases. This property is essential for safely containing hazardous substances.
Additionally, plastic's nonporous quality prevents the absorption of chemicals. This is particularly important for corrosive chemicals, which can easily damage other materials. For instance, hydrofluoric acid can eat through glass due to its ability to dislodge oxygen from its bonds. Plastic, on the other hand, provides a more resistant barrier, making it a safer choice for storing such corrosive substances.
The durability of plastic containers is another significant advantage. Polymers, which are the building blocks of plastics, are incredibly strong and resilient. They can withstand wear and tear, making them ideal for sealing strong acids and bases without the risk of breakage. This durability also ensures that hazardous chemicals remain securely contained, reducing the potential for accidental exposure or spills.
Furthermore, the customizability of plastic containers is a significant benefit. Polymer tanks, for instance, can be fabricated to hold specific chemicals with particular weight considerations in mind. This adaptability ensures that a wide range of chemicals can be safely stored, each in a container tailored to its unique properties. Plastic containers also come in various forms, such as bottles, tanks, and jerrycans, allowing for flexible storage options depending on the quantity and nature of the chemical.
