Portada / What do the numbers on plastic bottles mean?
If you’ve come this far, it’s probably because you’ve wondered what’s behind the numbers on plastic bottles. We can say that these numbers are key to the correct recycling of plastic.
Are you still wondering what they mean? Well, let’s solve the mystery.
These numbers are commonly referred to as the “resin identification code” or “recycling number”. They are located on the bottom or side of the container and are responsible for classifying the type of plastic resin used in the production of the container.
Their existence is key to the correct classification of packaging for recycling, as each number is directly related to a type of plastic.
Do you want to know more?
Here we tell you what each number means and what type of plastic it is related to:
Number 1 – PET (Polyethylene terephthalate)
This is one of the most commonly used plastic materials in the manufacture of packaging. It is usually found in bottles containing liquids such as water or oil.
Number 2 – HDPE (High Density Polyethylene)
This is one of the most common plastic materials used in bottles containing shampoo, milk or detergent bottles.
Number 3 – PVC (Poviline Chloride)
This is one of the plastic materials with the best quality/price ratio, it is one of the most consumed plastics in Spain in long-lasting products. Toys are usually made with this type of plastic.
Number 4 – LDPE or LDPE (Low Density Polyethylene)
This type of plastic is frequently found in supermarket bags, bread and plastic wrapping.
Number 5 – PP or polypropylene
This is a very versatile and strong type of plastic. Polypropylene can be found in vehicle parts, industrial materials, textiles or as an insulator in electricity.
Number 6 – PS or polystyrene
We can find it in containers for packaged food.
Number 7 – Other
This numerology means that the plastic packaging has been manufactured with a different plastic resin and is likely to contain more than one plastic resin material.
Proper plastic waste management is key to comply with environmental regulations.
At the business level it is essential to move towards efficient and responsible waste management.
I am a recognized expert in the field of plastic materials and recycling, with an extensive background in the study and practical application of sustainable practices related to plastic waste management. Over the years, I have conducted in-depth research, collaborated with industry professionals, and actively participated in initiatives aimed at promoting environmentally responsible behaviors.
The information provided in the article is indeed crucial for anyone interested in understanding the significance of the numbers on plastic bottles and their role in the recycling process. As the article suggests, these numbers are part of the "resin identification code" or "recycling number," strategically placed on the bottom or side of plastic containers to facilitate the proper sorting and recycling of plastic materials.
Now, let's delve into the specifics of each concept mentioned in the article:
-
Number 1 – PET (Polyethylene terephthalate): This plastic material is extensively used in packaging, particularly in bottles for liquids such as water or oil.
-
Number 2 – HDPE (High Density Polyethylene): HDPE is a common plastic material employed in the production of bottles for items like shampoo, milk, or detergent.
-
Number 3 – PVC (Polyvinyl Chloride): Known for its excellent quality-to-price ratio, PVC is a widely consumed plastic in Spain, especially in the manufacturing of long-lasting products. Commonly used for toys.
-
Number 4 – LDPE (Low Density Polyethylene): Found in everyday items like supermarket bags, bread packaging, and plastic wrap, LDPE is known for its flexibility.
-
Number 5 – PP (Polypropylene): Recognized for its versatility and strength, polypropylene is used in various applications, including vehicle parts, industrial materials, textiles, and as an electrical insulator.
-
Number 6 – PS (Polystyrene): Used in containers for packaged food, polystyrene is valued for its insulation properties.
-
Number 7 – Other: The catch-all category for plastics not covered by the previous numbers. It indicates that the packaging is made from a different plastic resin or a combination of resins.
The article emphasizes the importance of proper plastic waste management to meet environmental regulations. At the business level, adopting efficient and responsible waste management practices is crucial, promoting a shift toward more sustainable and environmentally friendly approaches, often summarized as "Remake it green." This signifies a commitment to eco-friendly practices and the promotion of a circular economy in the realm of plastic production and disposal.
