Eco-responsible Mailing Bags

RAJAPACK UK's eco friendly mailing bags help e-commerce businesses, fashion and clothing retailers, achieve sustainability without compromising on protection for items during transit. These eco mailing bags are manufactured from FSC-certified and PEFC-certified Kraft paper available in single-ply and heavy-duty 2-ply constructions. Through being kerbside recyclable with paper and cardboard streams, customers can dispose of eco friendly postal bags in the standard household paper recycling bin alongside envelopes and cardboard, with no specialist collection needed. From recyclable Kraft paper to compostable and recycled formats, we stock everything you need to send parcels sustainably across the UK.

Whether you’re replacing polythene, meeting a customer sustainability commitment or reducing packaging waste, our recyclable mailing bags are designed for daily e-commerce despatch. All recyclable mailing bags are chosen for responsible sourcing, verified recyclability and reliable transit protection, helping you cut plastic while keeping goods safe.

Our range covers:

• Kraft paper mailing bags – recyclable materials made from FSC-certified and PEFC-certified Kraft for clothing and soft goods despatch.
• Heavy duty paper mailing bag – made from 100% 70gsm Kraft paper, ideal for sending heavier and bulkier items, combining sustainability with strength.
• Recycled paper mailing bags - post-consumer recycled content, for buyers who want recycled mailing bags and recycled postage bags with a lower-impact material.
• Ecommerce packaging bags – features a block base, made from 50% recycled content, FSC-certified material and sized for bulky or irregularly shaped items that won’t fit a standard flat bag.
• Returnable Kraft paper shipping mailers – features a second adhesive strip, giving you outbound despatch and customer returns in a single recyclable bag.
• Compostable mailing bags - certified to EN 13432, the right compostable postal bags for brands with a composting end-of-life story.

Key features and benefits:

• Cut plastic from your despatch - swap polythene for eco friendly packaging bags that ship the same goods without single-use plastic film.
• Recyclable at kerbside - Kraft paper mailing bags go in the household paper and cardboard bin, with nothing to remove first.

• Keep goods moving - order eco friendly mailers and eco mailer bags with next-day UK delivery and a 98% next-day success rate.

Choosing the right eco friendly mailing bag:

When selecting recyclable, recycled mailer bags or compostable postal bags, consider:

• End-of-life route - decide whether the customer will recycle eco mailing bags at kerbside, compost, or return recycled plastic; this is the most important choice.
• Load type and weight - single-ply Kraft suits soft goods up to roughly 1.5kg; step up to 2-ply above about 2 to 3kg.
• Moisture exposure - treated Kraft is moisture-resistant for standard transit, while recycled polythene mailers give full waterproofing for sensitive contents.
• Bulk and shape - flat bags suit garments, while gusseted or block-base formats expand for bulky or irregularly shaped items.
• Returns programme - if customers return items, returnable Kraft bags remove the need for a separate return bag.
• Certification needs - check whether you require FSC or PEFC sourcing, EN 13432 compostability, or a stated recycled content percentage.

FAQs

What are eco friendly mailing bags?

Eco friendly mailing bags are postal bags designed to reduce plastic and packaging waste. They include recyclable Kraft paper mailing bags, recycled paper mailing bags, compostable mailing bags certified to EN 13432, and recycled polythene mailers.

Are recyclable mailing bags recyclable at home?

Yes. Kraft paper mailing bags are kerbside recyclable in the household paper and cardboard bin, with nothing to remove. The whole bag, including the peel-and-seal liner, goes in together; for on-pack labelling, follow OPRL guidance.

What is the difference between recyclable, recycled and compostable mailing bags?

Recyclable mailing bags can be recycled after use; recycled mailing bags are made from recycled material; compostable mailing bags break down under composting. Compostable film must be composted, not recycled, because it contaminates the kerbside paper recycling stream.

Are biodegradable mailers the same as compostable postal bags?

Buyers searching for biodegradable mailers or biodegradable postage bags usually want a certified option. Look for certified compostable bags, such as our EN 13432 range, rather than unverified biodegradable claims.

Are eco friendly mailing bags waterproof?

Treated Kraft paper mailing bags are moisture-resistant, not waterproof, and suit standard UK courier and Royal Mail despatch. For fully waterproof despatch, choose recycled polythene mailers, which combine water protection with recycled plastic content.

Where can I buy eco friendly mailing bags in bulk in the UK?

RAJAPACK UK supplies eco friendly mailing bags, eco mailers and sustainable mailers to thousands of UK businesses, with more than 70 years in packaging. Orders placed before 4pm ship next day, with volume discounts from three packs and eco friendly postal bags across every format.

What is the correct recycling route for paper mailing bags?

Kerbside paper and cardboard recycling bin, alongside corrugated boxes, envelopes and other paper packaging. Nothing needs to be removed. The entire bag including the peel-and-seal strip liner goes in together. This is distinct from polythene (supermarket plastic film collection, not kerbside) and compostable bags (composting, not paper recycling).
