Flat Poly Mailers


    Flat poly bags are designed for shipping non-fragile items that need minimal protection during shipment or are already packaged within a protective material. They are commonly used for shipping soft goods like clothing and bedding or items packed within a protective package like prescription drugs and shoe boxes. Don't settle for cheap, low quality packaging. Our products go through rigorous quality testing to ensure quality standards.

Quality Good - C/S needs helpReview by Richie
Order was sent and cost included shipping. UPS failed to deliver on time and as a result there was a delivery failure and shipping should have been refunded to MAILERSUSA. I needed the product and had to go to Staples to get temporary mailers and felt at a minimum I should have gotten the credit that the company should have gotten from UPS to go towards that unnecessary purchase (unnecessary had the product been delivered on time by UPS). I wasn't asking MAILERSUSA to pay for something. This was something that should have been coming from UPS. The C/S person from MAILERSUSA was not at all cooperative. (Posted on 5/24/2017)

Size and price exactly what I was looking for.Review by Matt
Perfect size and price for my product. Very durable. Shipping labels adhere better to the poly bag then a cardboard box. The poly bags were exactly what we were looking for. (Posted on 11/4/2015)

Great value for the priceReview by James
Seals great easy to handel and doesn't add a lot of weight for shipping. Have even had customers comment how happy they have been since I switched to these over the old ones I was useing. Protects my products very well from the elements and just add cardboard and will keep things safe from bending too. Very happy with my choise to use these for my mailings!!!!!!! (Posted on 4/1/2014)
