The G/17, 245×350 mm bubble mailer is a slightly more generous version of the A4 format. It is a few millimetres wider than the F/16, which makes it particularly well suited to thicker folders, thicker notebooks and hardcover books that benefit from a little extra room. This 10-piece pack is intended for webshop owners and small publishers.
What does the 10-piece pack contain?
The pack contains 10 bubble mailers, each measuring 245×350 mm on the outside. The net weight of one envelope is approximately 45 grams; the total gross weight of the pack is 0.495 kg. The envelopes can be stored flat, stacked on top of each other, and will fit comfortably in an average packing drawer or in an upright stand.
Material and bubble lining
The outer layer is a recycled, kraft-style paper with a natural brown tone. The inside is lined with a fine bubble film that absorbs vibrations and minor impacts during transit. The paper-based construction is a more environmentally friendly choice than fully plastic mailers, while the level of protection remains reliable.
Size and use
The 245×350 mm format is particularly suitable for medium-sized hardcover books, thicker notebooks, A4 printed matter, thicker folders and medium-to-large garments such as a folded knitted sweater or an adult-sized cotton T-shirt. If your webshop deals with publications, paper goods or textile products, this size usually provides a comfortable margin around the contents.
Closure system and opening
An adhesive strip runs along the upper edge of the envelope, protected by a release liner until use. Once the liner is removed, the flap folds down and the adhesive bonds permanently. The envelope cannot be resealed after opening, which assures your customer that the parcel has not been tampered with in transit.
Storage and durability
Store the envelopes in a dry, cool place, either flat or upright in a box. Avoid direct sunlight and prolonged moisture, as these can gradually weaken both the paper and the adhesive strip. Under appropriate conditions, the envelopes retain their full protective capacity for many months.
