Eco-responisble product protection


Heavy duty 2-ply Kraft paper mailing bags are a strong paper mailer for posting heavier, flatter goods such as books, catalogues and electronics. The two-ply thickness of Kraft paper give extra tear resistance in transit, so the bag holds up underweight where a single-layer paper mailer can split. A quick peel-and-seal strip closes each of the 2 ply paper mailing bags without tape or tools, which speeds up busy packing benches. The 2-ply 70 gsm paper is 100% recyclable, and its natural lightness keeps postage down on heavier parcels.

Available in three sizes. Sold in packs of 50, priced per pack.

Where do heavy duty paper mailing bags work best?

Heavy duty paper mailing bags suit despatch teams sending flatter, heavier goods that need a stronger paper outer and fast closure.

  • Posting books, catalogues and printed materials, as the 2-ply Kraft paper resists tearing better than a single-layer paper mailer.
  • E-commerce orders with flat or rectangular goods such as DVDs and cosmetics, where the brown Kraft surface takes labels cleanly.
  • High-volume packing benches, where the peel-and-seal strip closes each bag with no tape or tools.
  • Heavier paper-based despatch, where 2-ply 70 gsm paper carries the weight while staying light for postage.

Not for

  • Very fragile items sent without inner protection. Add cushioning such as bubble wrap inside the bag to limit movement.
  • Items that need rigid crush or corner protection. Use cardboard boxes when the product must not bend in transit.
  • Sharp or loose items that can strain the seams. Wrap or box them first so they don't puncture the paper.

Choose the right mailing bag

Heavy duty paper mailing bags are built for heavier flat goods without cushioning.

  • Choose heavy duty 2-ply Kraft paper mailing bags for a recyclable, tear-resistant paper mailer for heavier books, media and flat goods.
  • Choose Jiffy Green padded bags when the contents need cushioning, which these 2-ply paper mailing bags do not give.
  • Choose grey mailing bags when you want a water-resistant plastic mailer rather than paper.
  • Choose compostable mailing bags when you need a bag that breaks down after use rather than recyclable paper.

FAQs

What can I send in 2 ply paper mailing bags?

Flatter, square or rectangular goods such as books, DVDs, catalogues and cosmetics, provided the item fits without forcing the seams.

Do these bags need tape to close?

No. The quick peel-and-seal strip closes the bag without additional tape or tools.

Are they strong enough for heavy items?

Yes. The 2-ply 70 gsm Kraft paper is built for heavier goods. For fragile or high-value items, add internal cushioning before despatch.

Are the bags recyclable?

Yes. The Kraft paper is 100% recyclable, which suits operations moving away from plastic alternatives.

How do I choose the right size?

Measure the item's length and width, add its depth to each, then add 10mm to the width so it slides in without straining the seams.

strong and eco friendly. The only small criticism is that the edges of the glue strip do not stick down completely.
