What You'll Learn
USPS poly mailers are plastic mailing bags
Poly mailers, also known as polypropylene mailers, are plastic mailing bags used for shipping items through USPS. They are made from a thin layer of plastic that is tear-resistant, puncture-resistant, and waterproof, providing protection from moisture and other external elements during transit. Poly mailers are lightweight and take up minimal space, making them a cost-effective option for shipping, especially for small businesses or individuals looking to reduce shipping costs.
When using poly mailers for USPS shipping, it is important to select the correct size to avoid additional charges or delays. Poly mailers must be at least 2 mils thick for shipments up to 5 pounds and 4 mils thick for shipments up to 10 pounds. They are not suitable for shipments over 10 pounds. Proper packaging is also crucial to ensure items do not shift or get damaged during transport.
Most poly mailers have a self-adhesive strip for sealing, but plastic ties or packing tape can also be used. Shipping labels can be purchased online, at the post office, or through third-party services like Sticker Mule Ship. The cost of shipping depends on weight, destination, and any additional services required, such as insurance or tracking.
USPS offers shipping boxes, envelopes, mailers, and materials, including free and flat-rate options. However, using custom shipping materials can provide a better unboxing experience for customers, helping to establish a business's image. Poly mailers are a popular choice for businesses and individuals looking for a cost-effective, lightweight, and protective shipping solution for smaller items.

One of the biggest advantages of using poly mailers is their low cost compared to other shipping options. They are lightweight, which means they take up minimal space and can help to reduce shipping costs, making them a great option for small businesses or anyone looking to save money on shipping. For example, the cost of shipping a t-shirt in a standard box is $3.49, but this goes down to $1.92 when using a poly bag.

USPS has specific size guidelines for poly mailers
Poly mailers, also known as polypropylene mailers or plastic mailing bags, are a popular and cost-effective option for shipping items through the United States Postal Service (USPS). They are lightweight, sturdy, and waterproof, making them ideal for shipping smaller and less fragile items.
Secondly, poly mailers must adhere to certain thickness requirements. They must be at least 2 mils thick for shipments up to 5 pounds and 4 mils thick for shipments up to 10 pounds. Poly mailers are not suitable for shipments over 10 pounds. The overhang of the poly mailer should not exceed 0.5 inches when the package is lying flat, and it should have a uniform thickness.
It is worth noting that any non-paper envelope, including poly mailers, shipped as a "letter" would be considered non-machinable and subject to additional charges. This is due to the processing requirements of such mailers, which may include features like strings, buttons, or clasps. Therefore, it is important to consider the size and weight of your shipment and choose the appropriate category to avoid unexpected surcharges.
By following USPS's size guidelines for poly mailers, you can ensure that your shipments are secure, cost-effective, and compliant with USPS regulations.

USPS plastic mailers have a tamper-evident seal

These lightweight, waterproof bags are made from a thin layer of tear- and puncture-resistant plastic and are designed to protect items from moisture and other external elements during transit.
USPS poly mailers must adhere to specific guidelines. Firstly, size is important, as choosing a poly mailer that is too small or too large can result in additional charges or delays. When poly mailers are used, their overhang should not exceed 0.5 inches when the package is lying flat, and they must have a uniform thickness. For shipments up to 5 pounds, poly mailers must be at least 2 mils thick, while for shipments up to 10 pounds, they must be 4 mils thick. Poly mailers are not acceptable for shipments over 10 pounds.
USPS poly mailers can be sealed in several ways. Most poly mailers come with a self-adhesive strip that can be easily sealed to keep items secure. Other sealing options include plastic ties, packing tape, or tamper-evident seals. Tamper-evident seals provide an added layer of security, indicating that the package has been opened or altered. These seals are commonly found in bottle caps or jar lids and create an airtight barrier. Once broken, they cannot be resealed, clearly showing potential product tampering.
USPS also has specific tabbing requirements for folded self-mailers. These mailers must be sealed with glue or tabs made of paper, translucent paper, vinyl, or plastic. The number and size of tabs depend on the weight and design of the mail piece. For example, a bi-fold or tri-fold mailer weighing up to 3 ounces requires two non-perforated tabs on the top edge within 1 inch of the edges. Quarter-fold mailers require three non-perforated tabs: one on the leading edge, one on the trailing edge, and one on the lower leading edge.
Overall, USPS poly mailers offer a cost-effective and protective way to ship items, with the added option of tamper-evident seals for enhanced security.
