Flat mailers from Rigid Packaging are like envelopes, but way stronger. They are designed to keep important papers, photos, or even small crafts safe while they travel through the mail. Imagine sending a beautiful drawing to your grandma. You wouldn’t want it to arrive bent or torn, right? These mailers make sure that doesn’t happen. What are Flat Mailers Made Of? Our flat mailers are usually made from cardboard or thick paperboard. Think of the material cereal boxes are made from, but even sturdier. This strong material helps protect what’s inside from getting crushed or damaged. We use special machines to cut and fold the cardboard, and then glue it together to make a secure package. Some mailers also have a layer of plastic inside to keep moisture out, just in case it rains while your package is being delivered. Why Choose Flat Mailers? There are lots of reasons to use flat mailers instead of regular envelopes. First, they are much tougher. Regular envelopes can easily tear or bend, especially if they get caught in a sorting machine at the post office. Flat mailers can handle more rough treatment. Second, they help keep things flat. If you’re sending a photo or a certificate, you don't want it to arrive folded. Flat mailers prevent this. Third, they look more professional. If you’re a business sending documents to clients, using a flat mailer shows that you care about how your package arrives. Different Types of Flat Mailers Rigid Packaging offers different kinds of flat mailers to suit your needs. Some have a self adhesive strip, like on an envelope, so you can easily seal them. You just peel off the paper and press it closed. Others require tape or glue to seal. We also have mailers in different sizes, from small ones for photos to larger ones for documents. The color can also vary. You can get plain brown ones, white ones, or even mailers with a printed design. The choice is yours! How to Use Flat Mailers Using a flat mailer is simple. First, put your item inside the mailer. Make sure it fits snugly, but not too tightly. If it’s a fragile item, you might want to add a piece of cardboard for extra protection. Next, seal the mailer. If it has a self adhesive strip, peel off the paper and press the edges together firmly. If not, use strong tape to close all the seams. Finally, write the address clearly on the front of the mailer. Don’t forget to include the return address in case the package can’t be delivered. Who Uses Flat Mailers? Lots of different people and businesses use flat mailers. Photographers use them to send prints to clients. Artists use them to mail artwork. Businesses use them to send important documents like contracts and invoices. Even individuals use them to send greeting cards or invitations. Anyone who needs to send something flat and protected can benefit from using a flat mailer. The Benefits for Businesses For businesses, using flat mailers can save money and improve customer satisfaction. Because the mailers protect the contents, there’s less chance of items getting damaged in transit. This means fewer returns and complaints. Also, using professional looking packaging can help create a good impression with customers. It shows that you value their business and care about providing a quality service.
