Process for Recycling Used LDPE Film in Secondary Packaging
How is LDPE Film Recycled Once It Has Been Used for Secondary Packaging?
LDPE film is a popular PE that can be easily recycled after being used for secondary packaging. High-density polyethene (HDPE) and low-density polyethene (LDPE) film, along with coloured or printed film, must be separated before recycling.
Low-density polyethene (#4 plastic) is used to make bags with a thinner substance (such as produce bags), while high-density polyethene (#2 plastic) is used to make most plastic bags. Recycle bins are conveniently placed in many public places, especially in grocery stores.
Methods for Reusing LDPE Plastic
Several companies in the United States have pioneered advanced methods of recycling polyethene (PE) in recent years. Given the sustained expansion of the polyethene industry over the past decade and projections for the future, this recycling innovation is anticipated to become increasingly lucrative over time.
While everyone is aware of the environmental hazards posed by plastics, low-density polyethene (LDPE) stands out as a popular PE that can be recycled easily. Let’s go deeper into the recycling process and see what benefits you can reap from it.
LDPE: Is it Possible to Recycle?
High-density polyethene (HDPE) and low-density polyethene (LDPE) film, as well as coloured or printed film, must be separated before they may be recycled. The value of products made from recycled plastic is significantly impacted when the film is not separated. To avoid devaluing the final product due to cross-contamination, coloured or printed film and clear film are sent to separate processing streams.
Films with labels and unlabeled films also need to be separated. In the United States, labelled films can be cleaned up with the help of modern technologies before being recycled. That means less film will need to be flown abroad for recycling, and more can be recycled domestically.
How does one go about recycling LDPE plastic?
Once LDPE film has been sorted, it is shredded into flakes using grinders. After being crushed into flakes, plastic is cleaned to get rid of any remaining pollutants. To make the cleaned flakes more manageable, they are dried, melted, and formed into pellets.
New goods can be made using either 100% recycled LDPE or a mixture of recycled and virgin LDPE. Composite timber, building materials, agricultural supplies, and other products can all benefit from the use of recycled LDPE in the form of piping, sheets, films, and trash bags. In contrast, composite timber and plastic bags are common applications for recycled high-density polyethene.
Recycled plastic’s worth fluctuates depending on a number of circumstances, leading to a variety of grades of LDPE film, many of which can be converted to or replaced by LLDPE film due to its unique structural features.
- Premium film is created from 100% recycled LLDPE or LDPE that has been cleaned, dried, and inspected for clarity.
- Grade A LDPE film is extremely low in impurities; contaminants such as labels and dyes make up less than 5% of the film.
- LDPE or LLDPE film of Grade B maybe 20% more likely to have a colour than the film of any other grade.
- The lowest quality of the recycled film is produced using just clear, dry LLDPE or LDPE film (with either 50% colour or 50% transparency). Films made of HDPE and polypropylene (PP) are acceptable.
Where does recycled LDPE go?
Recycled LDPE film can be repurposed into many different plastic products.
- Wood-plastic composite
- Trash can liners and bags
- Garbage cans and compost heaps
- Envelope paneling for shipping
- Furniture
Why Should We Recycle Low-Density Polyethylene (LDPE)?
Companies that go to the trouble of recycling LDPE film reap benefits beyond only a cleaner, greener environment:
The cost of waste removal can be reduced by recycling LDPE because it eliminates the need to dispose of this material. There will be less garbage to collect, which should lower your garbage bill. Many recycling businesses offer free or low-cost program design and implementation, as well as fair compensation for your spent LDPE film.
Fewer pickups are needed. Due to waste film plastic’s smaller volume compared to waste corrugate, fewer deliveries and recycling collections are required, saving both time and fuel.
The production and recycling of LDPE need less energy than corrugate because it is sourced from natural gases.
Making an effort: The answer to the question of how much LDPE gets recycled is “not a lot.” Only 13% of LDPE and LLDPE containers and packaging were recycled, according to data given by the Environmental Protection Agency (EPA) in 2015. Plastic The state of recycling technology is improving rapidly, but no amount of progress will be made unless LDPE is recycled.
Reputational benefits from planting seeds: A company’s image can greatly benefit from its commitment to sustainability. The more eco-conscious customers you can convince that you’re using recycled materials, the better.
Use LDPE plastic, which can be recycled, in your operations.
To be “greener,” don’t rule out LDPE film when reevaluating your secondary packaging options. All of the LDPE film used in testing at EDL Packaging Engineers is recycled because of the company’s dedication to environmental responsibility. Whether your products are picked and placed in a tray for stability before being wrapped or bundled and shrink-wrapped, our engineers can help you evaluate and discover the optimal way to include LDPE film in the secondary packaging of your products.
