If you've ever looked at the bottom of a plastic container, you may have noticed a number surrounded by three arrows. These numbers are part of what's called the plastic's resin identification code, which represents the kind of plastic the product is made of. The number 2 on the bottom of plastic containers indicates that they are made of HDPE plastic, which is considered one of the safest forms of plastic. It is a stiff plastic used for heavy-duty items like milk jugs, detergent bottles, and shampoo bottles. HDPE plastic is also the most commonly recycled plastic and can be reused and recycled.

What You'll Learn
The number indicates the type of plastic
The number on the bottom of a plastic container is part of the plastic's resin identification code, indicating the type of plastic the product is made of. The numbering system was introduced by the Society of the Plastics Industry to help recyclers identify the type of plastic used in bottles and containers.
Number 2 plastic, or High-Density Polyethylene (HDPE), is considered one of the safest forms of plastic. It is a stiff plastic used to make heavy-duty items like milk jugs, detergent and oil bottles, toys, and some plastic bags. HDPE plastic is very durable and does not break down under exposure to sunlight or extremes of heating or freezing. This makes it a popular choice for outdoor products such as picnic tables, plastic lumber, waste bins, and park benches.
HDPE is the most commonly recycled plastic. It is relatively simple and cost-effective to recycle, and the recycled material can be used to create new products such as plastic bottles, fleece clothing, carpets, sleeping bags, and pillows.
While HDPE is considered safe, it is important to remember that all plastic products can leach toxic chemicals when heated or damaged. Therefore, it is recommended to use alternative materials like metal and glass whenever possible.

Number 2 plastic is HDPE
The number on the bottom of plastic containers is an indicator of the type of plastic the container is made of. This numbering system was introduced by the Society of the Plastics Industry to help recyclers identify the composition of plastic bottles and containers.
HDPE is widely recycled and is considered one of the safest forms of plastic. It is accepted at most recycling centers and can be reused without any harm. The recycling logo with the number 2 inside the chasing arrows indicates that this plastic can be easily and efficiently recycled up to 10 times. Clear HDPE containers are recycled back into new containers, while colored HDPE is turned into items like pipes, lumber, toys, lawn furniture, pens, and floor tiles.
Some common uses of HDPE include milk jugs, detergent and oil bottles, household cleaners, shampoo bottles, toys, some plastic bags, electrical insulation, automotive parts, and fuel tanks.

It is considered one of the safest forms of plastic
Plastic containers with a number 2 on the bottom are considered one of the safest forms of plastic. Number 2 plastic, also known as HDPE (high-density polyethylene), has a high strength-to-density ratio, resulting in excellent wear resistance. This type of plastic is very durable and can withstand heating and freezing without breaking down, making it suitable for various weather conditions.
HDPE products are safe for reuse and can be recycled up to 10 times. Clear containers made from HDPE number 2 plastic can be recycled back into new containers, while coloured HDPE 2 can be turned into pipes, lumber, toys, lawn furniture, pens, and floor tiles.
Number 2 plastic is widely considered safe for food storage and does not contain harmful chemicals such as BPAs. It is important to note that while number 2 plastic is relatively safe, it is still recommended to minimise the use of plastic around food and heat sources, as all plastic products can leach toxic chemicals when damaged or heated.
When choosing plastic products, it is essential to consider the potential health and environmental impacts. Number 2 plastic is a safer choice than plastics with recycling labels 3, 6, and 7, which should be avoided or rarely used, especially with food and drinks. It is always advisable to opt for alternative materials, such as metal and glass, whenever possible.

It is used for heavy-duty items like milk jugs and detergent bottles
The number 2 on the bottom of plastic containers is part of the plastic's resin identification code, which represents the kind of plastic the product is made out of. It is also known as the recycling symbol and is used to help recyclers identify what bottles and containers are made of.
Number 2 plastic is one of the safest forms of plastic and is considered the most commonly recycled plastic. It is hard-wearing and does not break down under exposure to sunlight or extremes of heating or freezing. It is known as High-Density Polyethylene (HDPE) and is used for more heavy-duty items like milk jugs, detergent bottles, shampoo bottles, and grocery bags.
HDPE is also used for products that require durability and weather-resistance, such as picnic tables, plastic lumber, waste bins, park benches, and bed liners for trucks. It is a popular material for recycled plastic raised garden beds.
Products made of HDPE are reusable and recyclable. The recycling process for HDPE plastic is relatively simple and cost-effective, making it a good choice for secondary use.

It is the most commonly recycled plastic
The number 2 on the bottom of a plastic container is part of the Resin Identification Code (RIC) system, also known as the plastic recycling code. This system was devised in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association) to help recyclers identify the type of plastic an item is made of. The number 2 plastic is one of the safest and most commonly recycled plastics, along with number 1.
Number 2 plastic, or high-density polyethylene (HDPE), is a common plastic that is relatively easy to recycle. It is used to make items like milk jugs, detergent containers, shampoo bottles, oil bottles, toys, and some plastic bags. HDPE is hard-wearing and resistant to sunlight, heating, and freezing. Due to these properties, it is often used to create items such as picnic tables, plastic lumber, waste bins, park benches, and bed liners for trucks. It is also a popular material for recycled plastic raised garden beds.
Products made from HDPE can be recycled into new products through a relatively simple and cost-effective process. Once collected and sorted, the plastic is cleaned, reprocessed by melting, and then used to produce new items. Recycled HDPE can be transformed into pellets sold to plastic manufacturers or used to create floor tiles, fencing, writing pens, and other products.
While the presence of the recycling symbol on a plastic item indicates its recyclability, it does not guarantee that it can be recycled or is made from recycled materials. The acceptability of specific plastics for recycling varies across different locations, and certain plastics may be more challenging to recycle than others. For instance, while LDPE plastic bags are technically recyclable, they are not typically accepted in household curbside recycling services due to the risk of tangling in recycling machinery.
It is important to note that all plastic products can leach toxic chemicals when heated or damaged. Therefore, it is recommended to transition to alternative materials like metal and glass whenever possible.
