What Are Compostable Postage Bags? (B2B Use Only)
Compostable postage bags are lightweight shipping bags designed for short-term transport through postal and courier systems.
They are commonly used for mailing documents, apparel, soft goods, and boxed items, where flexible outer packaging is required. These bags are manufactured from certified compostable materials and are intended as an alternative to conventional plastic poly mailers.
Compostable postage bags supplied by manufacturers like us are for business and wholesale use only. They are not designed for retail consumer packs or household storage.
Postage Bags vs Mailer Bags vs Courier Bags
In B2B packaging, these terms are closely related but not identical.
- Postage bags describe the shipping context—items sent through postal or mailing systems.
- Mailer bags describe the bag structure, such as self-adhesive mailers, dual-seal return mailers, or open-top mailer bags.
- Courier bags are typically used in e-commerce fulfilment and logistics operations, where high shipping volume, durability, and operational efficiency are required.
For high-volume e-commerce and logistics shipments, buyers typically select compostable courier bags designed for fulfilment workflows.
To compare different sealing structures and formats, buyers should review compostable mailer bag options.
Typical B2B Use Cases for Compostable Postage Bags
Compostable postage bags are commonly used in the following business shipping environments:
- Mailhouses and mailing centres
- E-commerce fulfilment centres
- Subscription box shipping
- Lightweight apparel and soft-goods mailing
- Document and small-parcel postal dispatch
They are designed for short-term shipping and handling, rather than long-term storage.
Materials & Compostability (PLA / PBAT)
Our compostable postage bags are produced using PLA and PBAT-based compostable material formulations.
These materials are designed to break down under controlled composting conditions, reducing long-term environmental impact compared with traditional plastic packaging.
It is important to note that compostability depends on certification scope and disposal environment. Some compostable products are suitable for industrial composting only, while others may meet home composting standards under specific conditions.
To understand how compostability standards apply to different mailer and courier bag products, buyers should refer to certified compostability guidelines and product-specific certification documentation.
How Buyers Should Choose the Right Bag Format
Compostable postage bags are suitable for many mailing applications, but they are not always the best choice for every shipping workflow.
Buyers should consider:
- Self-adhesive or dual-seal mailer bags for fast manual packing and return programs
- Open-top mailer bags for automated or heat-sealing packing lines
- Dedicated compostable courier bags for high-volume e-commerce fulfilment and logistics operations
Selecting the correct bag format helps reduce packing errors, improve efficiency, and avoid misuse.
