When you're done with your eco-friendly mailers, it's important to dispose of them properly. This is true for any type of mailer, but some disposal methods are better than others. The best way to dispose of your eco-friendly mailers is by recycling them at a local recycling facility. If you don't have easy access to a recycling facility, consider finding one online and making arrangements to drop off your mailers there when you're done using them. Plastic mailing envelopes can also be recycled at most facilities that accept paper products. However, it's important that these envelopes not contain any metal fasteners or clips, as these can cause serious damage when run through an industrial shredder designed for paper shredding only!
