Biodegradable Padded Envelopes: Sizes, Prices & Where to Buy

Biodegradable Padded Envelopes: What You Need to Know

Biodegradable padded envelopes are cushioned mailers made entirely from paper-based materials that break down naturally after use. Unlike traditional bubble mailers lined with plastic bubble wrap, these use recycled paper fibre padding, giving you the same protection without the environmental cost. For businesses looking to cut plastic out of their packaging without compromising on quality, they're the straightforward swap.

The Jiffy Green biodegradable padded envelope option from Globe Packaging covers nine sizes, from a compact 105x229mm to a large 341x483mm, with prices starting at £10.39 for 50 pieces. Every part of the bag is recyclable and biodegradable: a tough 90gsm paper outer, 100% recycled fibre cushioning, and a peel-and-seal closure that needs no tape or glue. When your customer is done with it, the whole envelope goes straight into the paper recycling bin.

Choosing the right size is the most important decision, and it comes down to what you're shipping. 

Jiffy Green Biodegradable Padded Envelopes

Jiffy Green biodegradable padded envelope is a mailing bag that combines a protective cushioning layer with an outer shell, all made from materials that break down naturally over time. 

Unlike traditional bubble mailers, which use plastic-based bubble wrap lining, Jiffy Green biodegradable envelopes use 100% recycled cushioning paper fibres on the inside and a tough paper outer. The result is a bag that performs like a conventional padded envelope but leaves almost no environmental footprint behind.

Jiffy Green padded bags come in nine sizes, suitable for various use cases.

Jiffy Green Biodegradable Padded Envelope Bag Sizes

Jiffy Green padded bags come in nine sizes, ranging from 105 x 229 mm to 341 x 483 mm. All dimensions refer to the internal usable space, so what you see is what fits.

1. 105x229mm

The smallest size in the Jiffy Green range, the 105x229mm envelope is ideal for slim, lightweight items that still need cushioning. Think gift cards, USB drives, SIM cards, small jewellery pieces, or folded documents. It's a compact option that keeps postage costs low while still offering the full paper-padded protection of the larger sizes.

Price: Starts at £10.39 for 50 pieces

2. 135x229mm

Slightly wider than the smallest size, the 135x229mm bag gives you a bit more room without jumping to a much larger format. It works well for items like phone cases, thin paperback books, folded clothing accessories, or small electronics.

Price: Starts at £11.39 for 50 pieces

3. 165x280mm

The 165x280mm size is one of the most versatile in the range. It handles standard A5 documents, flat, small hardcover books, cosmetics, and boxed accessories comfortably. If you're unsure which size to start with for a mixed product range, this is often a solid middle-ground choice.

Price: Starts at £15.79 for 50 pieces

4. 195x280mm

The 195x280mm bag steps things up noticeably in width, making it a great fit for items that are slightly bulkier or oddly shaped. Folded t-shirts, small accessory sets in boxes, A5 notebooks, and mid-sized electronics all sit comfortably in this format. It's a popular choice for e-commerce sellers shipping lifestyle and fashion products.

The reinforced corners and no-side-seam construction really start to prove their worth at this size. When you're packing something with a bit of weight or rigidity, the last thing you want is a bag that splits at the edges mid-transit.

Price: Starts at £16.49 for 50 pieces

The 195x280mm size is best for small accessories, A5 notebooks, and mid-sized electronics.

5. 195x343mm

Same width as the previous size but notably taller, the 195x343mm envelope is well-suited for longer items that don't need extra width, such as rolled documents, longer folded garments, boxed pens or tools, and A4 documents folded once. It's a specialist shape that solves a specific problem neatly.

Price: Starts at £17.69 for 50 pieces

6. 225x343mm

The 225x343mm bag marks the start of the Jiffy Green range that accommodates genuinely substantial items. This size handles A4 documents flat without folding, which is a significant advantage for businesses sending contracts, brochures, portfolios, or certificates that must arrive in pristine condition.

It also works well for medium-sized hardcover books, folded clothing items, tablet accessories, and small framed prints. The 90gsm paper outer and reinforced construction mean the bag holds its shape even when packed firmly, giving contents solid all-round protection throughout the delivery journey.

Price: Starts at £19.95 for 50 pieces

7. 245x381mm

The 245x381mm size is a strong all-rounder for businesses that ship a mix of medium and large items. It comfortably fits A4 paperwork, hardback books, small boxed products, and folded garments without their contents shifting around. The extra internal space also speeds packing, which adds up over high-volume shipping runs.

Price: Starts at £25.95 for 50 pieces

8. 295x458mm

Step up to the 295x458mm size, and you're firmly in large-item territory. This bag handles thick A4 catalogues, multiple documents together, larger clothing items, small posters, and boxed products with ease. It's the go-to size for publishers, retailers, and fulfilment centres dealing with varied, bulkier stock.

Price: Starts at £30.95 for 50 pieces

9. 341x483mm

The largest size in the Jiffy Green range, the 341x483mm bag is built for big jobs. This is the envelope you reach for when everything else feels too small: large-format prints, thick hardcover books, multiple A4 documents unfolded, bulky garments, or larger boxed products all fit without compromise.

At this size, the structural advantages of the Jiffy Green construction are most apparent. The reinforced corners, double-glued bottom flap, and seamless sides work together to handle the extra weight and volume without the bag giving way. 

For businesses in publishing, print, retail fulfilment, or corporate gifting, the 341x483mm bag handles items that would otherwise require a box. That means lighter shipments, lower postage costs in many cases, and packaging that your customers can recycle or compost when they're done with it. Here's a quick summary of what fits well in this size:

• Large format A3 documents or prints

• Thick hardcover books and coffee table books

• Multiple unfolded A4 documents or brochures together

• Larger folded garments, such as jumpers or jackets

• Boxed products up to approximately 330x460mm

• Corporate gift sets and product bundles

If you regularly ship items that push the limits of smaller padded envelopes, the 341x483mm Jiffy Green bag is the practical, sustainable answer, no tape required, paper-based throughout, and no compromises on protection.

Price: Starts at £35.95 for 50 pieces

Keep your documents and items secure with padded envelopes.
