This is an expandable kraft paper mailing bag. Gusseted sides and a bottom fold let it open out to hold bulkier soft goods and stand on its own, while a peel-and-seal flap closes it in one motion and a tear strip opens it cleanly. It prints in water-based ink for a natural matte finish or in UV for sharper, more durable graphics. Because it is all paper, it recycles in the standard stream and replaces the plastic courier satchel for apparel, textiles, and other soft, non-fragile goods.

An expandable bag, not a flat envelope

The gusset is the reason to choose this over a flat mailer. Folded sides and base open to a depth that holds folded apparel, several items, or a bulky soft product without straining the seams, and the flat bottom lets the bag stand for easy packing. Closed, it lies slim for storage and postage. We size the gusset to the volume you ship so the bag holds its contents snug rather than half empty.

Peel-and-seal and tear strip

The closure is built for fast fulfilment and clean opening. Staff peel the liner and press the flap to seal with no tape, and the recipient pulls the tear strip for a clean, tamper-evident open. A double peel-and-seal option adds a second adhesive strip so a customer can reseal and return an item in the same bag, which removes the cost of a separate returns mailer.

Water-based or UV printing

Match the print method to the look and the duty. Water-based ink soaks into the kraft fiber for a soft matte finish, the most natural recycled look and the cleanest recyclability, which suits eco-forward branding, though colors stay muted on brown kraft and dense whites are limited. UV cures on the surface for sharper detail, brighter and more opaque color including white on kraft, and better rub and moisture resistance, at the cost of the natural matte feel and a heavier ink layer. As a rule, choose water-based for the eco look and recyclability, and UV for vivid, durable, high-detail graphics.

Plastic-free paper that recycles

The bag body is single-material kraft with no poly lining, so it recycles in the household paper stream and carries an honest plastic-free claim, unlike a poly satchel. The peel-and-seal strip uses an adhesive whose standard release liner is discarded at packing, so for a fully plastic-free line we offer a paper-based release liner. Water-based ink keeps the cleanest recyclability, while heavy UV coverage adds a cured layer, so for strict repulpability we will review the ink and coverage against your market rules. FSC kraft and recycled content are available on request.

Sizes and ordering

Size is cut to your shipment so the bag fits the goods and does not waste postage. Standard courier sizes are stocked patterns, and any custom size is available. For soft, non-fragile goods the standard bag is enough, and for items that need cushioning we add a honeycomb-paper padded lining or point you to the foam-insert mailer instead. Send your contents, dimensions, quantity, destination, and artwork, and we return a dieline, a recommended spec, and a quote, with a blank sample or a printed proof before the run. There is no strict minimum, though unit cost drops with volume. FSC chain of custody, ISO 9001, and ISO 14001 are on file.

FAQ

Water-based or UV printing for my bag?

Choose water-based ink for a natural matte look and the best recyclability, which fits eco branding on kraft. Choose UV for sharper, brighter, more durable graphics and opaque white on brown kraft. We will advise based on your artwork and how much color coverage it has.

Is the bag fully plastic-free?

The kraft body is recyclable and plastic-free. The standard peel-and-seal strip has a release liner that is discarded at packing, so for a fully plastic-free spec ask for a paper-based liner. Water-based ink keeps the cleanest recyclability.

Will it protect what I ship?

The standard bag suits soft, non-fragile goods such as apparel and textiles. For items that need cushioning, we add a honeycomb-paper padded lining, or for fragile and multi-part products the foam-insert mailer is the better fit.

What order quantity makes sense?

There is no strict minimum, but print plates and setup spread over the run, so small batches carry a higher unit cost and the price falls with volume. Tell us your launch quantity and reorder forecast and we will advise on the break points.

Do you handle international shipping?

Yes. We export under standard Incoterms such as FOB and CIF, and we advise on carton and pallet fit so the order ships efficiently and lands at a sensible cost.
