Recycling plastic with labels: Should you remove them?
Plastic is a highly versatile material that can be formulated to meet a wide range of specific material needs. However, its versatility also means that it can be challenging to recycle. The recycling process for plastic involves heat that burns away paper labels and glue from containers. However, if the label is made from a different type of plastic than the container, it can contaminate the recycling process. While a few plastic labels may not ruin a large load of recycling, contamination affects the quality and value of the recycled material.
Different recycling facilities have different capabilities, and some types of labels are more easily recyclable than others. When a plastic container has a label made of the same type of plastic, both can be recycled together. However, when the label is made from paper or a different type of plastic, it becomes a contaminant. Most local recycling centres do not require the removal of labels from products before tossing them into the recycling bin. The heat during the recycling process ensures that paper labels and glue are burned away.
While it is not necessary to remove labels from plastic containers before recycling them, it is good practice to do so when possible. This is because recycling contamination is a significant issue, and even a small amount of contamination can impact the quality and value of the recycled material. It is also important to note that recycling practices vary from one city, county, or state to another, and some recycling programs may require participants to remove labels from plastic before recycling. Therefore, it is always good to check with your local recycling program about their specific policies on removing labels.
To reduce plastic waste and improve the effectiveness of recycling, it is essential to reduce plastic consumption, especially single-use plastics. Additionally, when purchasing plastic products, consumers can look for products with labels that are easily removable or made from the same type of plastic as the container. This will help reduce contamination during the recycling process and improve the overall quality and value of recycled materials.

Plastic labels as contaminants in the recycling process
Plastic labels can contaminate the recycling process when they are made from a different type of plastic than the container. This is because different types of plastics require different recycling processes. For example, PET and HDPE are easy to recycle, while polycarbonate is hard to recycle. If a plastic label is made from a different type of plastic than the container, it can make the recycling process more difficult and reduce the quality and value of the recycled material.
However, it is not always necessary to remove plastic labels before recycling. Most local recycling centers do not require the removal of labels from plastic containers. The heat during the recycling process burns away paper labels and glue from containers. While some contamination is inevitable, a few plastic labels will not ruin a large load of recycling. Nevertheless, removing labels when possible is considered good practice.
To facilitate the recycling process, it is important to have clear and informative labels on plastic products. Proper labeling can help consumers identify which type of plastic the product is made of and how recyclable it is. This can prevent incorrect disposal and reduce the amount of waste that ends up in landfills and the environment. Additionally, clear labels can save consumers time when sorting their recyclables.
To determine the recyclability of a plastic product, individuals can look for a recycling code on the product or its packaging. These codes range from 1 to 7 and indicate the type of plastic and its recyclability. For example, #1 and #2 plastics are almost always recyclable, while #5 and #7 plastics may be recyclable in certain locations but not in others. Checking with local recycling programs or solid waste utilities can provide specific information on accepted materials and label removal requirements.

The Society of the Plastics Industry's (SPI) classification system
The Society of the Plastics Industry (SPI) introduced its resin coding system to identify the various resins found in plastic bottles and rigid containers. The SPI coding system, also known as the Resin Identification Code, was created to make it easier to sort and dispose of different kinds of plastics. This is especially useful for plastic recycling centres, as many plastic resin types look similar.
The SPI System also helps Electronic Imaging Materials (EIM) classify different types of plastics and, in doing so, better categorise inherent characteristics that can affect adhesive bonding. For example, the type of adhesive used for a label depends on the specific type of surface, and plastics can vary greatly.
The SPI code, which includes a "chasing arrow symbol", must be moulded or imprinted into the bottom of plastic products. It is important to note that the presence of an SPI code does not indicate that the product is recyclable or is recycled locally. #1 and #2 plastics are almost always recyclable, while #5 and #7 plastics may be recyclable in some places but not in others. Any other number usually is not suitable for curbside recycling.
The SPI, founded in 1937, is a nonprofit organisation that represents the entire supply chain for the plastics industry, including processors, recyclers, suppliers, equipment and machinery manufacturers, and brand owners. In 2010, the organisation began doing business as SPI: The Plastics Industry Trade Association, before changing its name to the Plastics Industry Association (PLASTICS). The SPI also produces NPE, one of the world's largest plastics industry trade shows, and publishes statistical reports on the U.S. plastics industry.

The use of glue for labels on plastic containers
Labelling is an important aspect of product packaging, and the use of glue for labels on plastic containers is a common practice. The choice of adhesive is crucial to ensure the label adheres securely and remains intact during the product's shelf life. One popular option for gluing labels on plastic containers is hotmelt adhesives. These adhesives offer high flexibility over a wide temperature range, strong initial adhesion, and resistance to humidity, enhancing the label's appearance and durability.
Hotmelt adhesives are highly compatible with plastic containers due to their ability to bond effectively with plastic surfaces. They can withstand temperatures as low as 40°C below zero, making them suitable for products that require refrigeration or freezing. Additionally, their resistance to humidity helps maintain the label's integrity, ensuring that it remains intact and legible even in moist environments.
However, the use of glue for labels on plastic containers is not without concerns. One issue to consider is the potential for adhesive chemicals to migrate into the contents of the container, particularly in the case of food packaging. While the likelihood of this occurring may be low, it is a valid concern, and the use of non-toxic adhesives is essential to mitigate this risk. Some consumers may also be concerned about the environmental impact of adhesive residues during the recycling process.
To address these concerns, manufacturers can opt for adhesives that are specifically designed for food-safe applications and are compatible with the recycling process. By selecting the appropriate adhesive, manufacturers can ensure that their products meet safety standards and minimise any potential negative impact on the environment. It is also important to consider the specific requirements of the container and the production process when choosing an adhesive. For example, the speed of label placement in industrial processes and the type of application system used can influence the choice of adhesive to ensure efficient and effective labelling.
In conclusion, the use of glue for labels on plastic containers is a complex process that requires careful consideration of various factors. By selecting the right adhesive, manufacturers can ensure the labels' durability, aesthetics, and safety while also minimising any potential environmental impact during recycling. Ultimately, the choice of adhesive plays a crucial role in the overall success of the product and its packaging.
