Eco Kraft Mailing Bags

What Are Kraft Mailing Bags?

Kraft mailing bags are postal bags made from brown Kraft paper rather than polythene or plastic. The word “Kraft” refers to the manufacturing process used to produce the paper, which results in a strong, durable material with a natural brown finish. Our Kraft bags are made from 120gsm single ply paper, which provides a good balance of strength and flexibility for mailing purposes.

Unlike polythene mailing bags, Kraft paper mailing bags are entirely plastic free. They can be recycled in standard household paper recycling, composted at home and will biodegrade naturally. This makes them a fully sustainable choice for businesses looking to move away from plastic packaging without compromising on quality or practicality.

Eco-Friendly Mailing Bags for E-Commerce

For e-commerce businesses, packaging is one of the most visible parts of the customer experience. More and more consumers expect the brands they buy from to use sustainable packaging, and Kraft paper mailing bags offer a practical way to meet that expectation without adding complexity to your packing process.

Kraft mailing bags work just like polythene postal bags: they have a peel and seal closure, they are sized to match Royal Mail’s PiP guidelines, and they are quick to pack and despatch. The difference is that when your customer receives their order, they can recycle the bag with their household paper recycling rather than having to find a specialist plastic recycling point.

Paper mailing bags for clothes are particularly popular with fashion and lifestyle brands that want their packaging to reflect a commitment to sustainability. The natural brown Kraft finish also offers a clean, premium look that complements handwritten notes, branded stickers and other personal touches.

Recyclable, Biodegradable and Compostable

Our Kraft mailing bags carry five eco credentials: they are made from 100% recycled paper, they are recyclable in standard household recycling, they are biodegradable, they are compostable, and they are entirely plastic free. This is a meaningful step beyond recycled polythene mailing bags, which still require specialist collection points for recycling and may not biodegrade.

For businesses that report on their environmental impact, or that want to communicate clearly to customers that they care about the environment, Kraft paper mailing bags provide a simple, auditable claim: fully plastic free, recyclable in household waste, and made from recycled materials.

Kraft Mailing Bags vs Polythene Mailing Bags

Both Kraft and polythene mailing bags serve the same basic purpose, but they differ in materials and environmental credentials:

Kraft mailing bags are made from paper, are plastic free, biodegradable and compostable. They can be recycled in standard household paper recycling. They have a natural brown finish and a slightly more premium feel. They are water resistant but not waterproof, so they are best suited to items that do not require full moisture protection.

Polythene mailing bags are made from recycled plastic, are fully waterproof and are generally lighter. They are recyclable at supermarket carrier bag collection points. They tend to be more economical per unit, making them a practical choice for very high-volume despatch.

For many businesses, the choice comes down to whether plastic free packaging is a priority. If it is, Kraft bags are the clear answer. If full waterproofing or the lowest possible cost per unit is more important, Polythene Mailing Bags remain a strong option.
