Frequently Asked Questions

We've answered some common questions on mailing bags below.

What Are Postage Bags Called?

Postage bags are known by several names depending on usage. Here are just a few:

  • Postal Bags: Used for sending letters, documents, and small flat items via postal services.
  • Mail Bags: Large, durable sacks for transporting bulk mail, often used by postal services and businesses.
  • Parcel Bags: Designed for shipping parcels of various sizes, providing extra protection for heavier items.
  • Shipping Bags: Versatile bags for sending goods through couriers or postal services, suitable for different weights.
  • Poly Mailers: Lightweight, waterproof plastic bags ideal for clothing, documents, and soft goods.
  • Courier Bags: Secure, tamper-evident bags for confidential documents and valuable items.
  • Packaging Bags: General-purpose bags for protecting, storing, or shipping goods across industries.

What is the Use of a Mailing Bag?

Mailing bags are used to securely ship and protect items during shipping. Characteristically, they are often lightweight, durable and weather-resistant, which makes them ideal for both small and large businesses seeking cost-efficient and effective packaging options.

Should I Choose a Box or Mailing Bag?

The choice between a box and a mailing bag depends on the size, weight, and level of protection your items need. Mailing bags are ideal if you need to pack lightweight items like clothing, books, and accessories. Large mailing bags work well for bulkier soft goods and can also protect fragile items when paired with bubble lining or additional padding.

Boxes are great for adding an extra layer of protection, especially if you want added security for fragile items. They’re also the better choice for heavy items, offering more structural support during transit.
