Custom biscotti mylar bags are printed, resealable pouches made from layered barrier film, so your twice-baked biscuits stay crunchy from the oven to the last one in the bag. They stand on a shelf, survive the post and carry your branding front and back.

Crunch Is the Whole Point
Biscotti are baked twice to drive out moisture, and that dryness is what gives them their snap when dunked in coffee. The moment they sit in a paper bag or a loosely closed tub, they start pulling moisture back from the air and soften. For a baker selling at a counter that might not matter, because the bag is opened the same day. For anyone selling online, stocking delis or sending biscotti as gifts, the packaging has to hold that crunch for weeks.
Mylar bags are built from several layers of film laminated together, usually including a metallised or foil layer that blocks light, air and moisture far better than paper or a single plastic layer. Add a zip closure and a heat seal across the top, and the biscotti inside are protected until the customer tears the notch and opens them. After that, the zip lets them close the bag again between servings, so the last few biscuits taste as good as the first. Softer bakes that need less protection from humidity go into our cookie mylar bags for softer bakes.
Biscotti Mylar Bag Shapes for Long, Slim Biscuits
Biscotti are long and narrow, which affects the bag shape more than most bakes. A stand-up pouch with a gusseted base suits loose biscotti packed upright, and it gives a large front panel for your branding on a shop shelf. A flat pouch suits a neat row of biscuits laid side by side and posts easily through a letterbox. Taller, slimmer pouches show off the length of traditional almond biscotti, while wider bags suit mini biscotti or broken pieces sold as a coffee nibble.
If you sell several flavours, one pouch size with a different printed panel for each flavour keeps production simple. If you sell a small gift bag and a large family bag, we can make both in the same design so they look like one range.
- Stand-up pouches with a gusseted base for shelf display
- Flat three-side seal pouches for letterbox delivery
- Tall slim pouches that suit full-length biscotti

Film Choices and Windows
A fully metallised film gives the strongest barrier and a bright silver or gold interior that looks smart when the bag is opened. A matt outer layer softens the look and photographs well for online listings. Kraft-effect pouches combine a paper-look outer face with a barrier lining, which suits artisan bakeries that want a rustic feel without giving up shelf life.
Windows are a judgement call. Customers like seeing the biscotti before they buy, especially when they are studded with nuts, chocolate or dried fruit. A window does let some light reach the product, so it is best on bags with a shorter shelf life or those sold quickly. Keep the window small and shaped, such as a narrow strip or a biscotti outline, to show the bake while keeping most of the barrier film intact. A clear panel option on the front is described on the mylar bags with a window panel page.
Designing the Front and Back Panels
The front of a biscotti bag has one job: make someone pick it up. A strong brand name, a clear flavour name and a hint of what is inside, such as almond and orange or dark chocolate and hazelnut, is usually enough. Food photography works well on gloss film, while illustrated designs and simple typography look elegant on matt.
The back panel carries the practical information. Leave room for ingredients and allergens, net weight, storage advice, best-before date and your business address, as these details are needed for food sold to the public. Many bakers print a blank area for a sticker so the same bags can be used across batches with dates applied by hand. If you change flavours often, printed labels applied to plain pouches let you run one bag design.
- Flavour-specific front panels in one shared layout
- Space for ingredients, allergens and net weight
- Blank label area for batch and best-before dates
- Serving suggestion or dunking tip to show personality
Who Packs Biscotti in Printed Pouches
Home bakers who have outgrown cellophane bags and ribbon are often the first to switch, usually when they start selling online and need packaging that survives a courier. Independent bakeries stocking local delis and farm shops want a bag that looks professional next to big brands. Coffee shops and roasters sell biscotti alongside their beans, and a matching printed pouch makes the pairing feel planned.
Corporate gift companies and hamper makers also use small biscotti pouches as add-ons, because a slim bag tucks easily beside a bottle or a jar. Wedding and event planners order them as favours, printed with names or a simple monogram.
Filling and Sealing Without Breakages
Biscotti are brittle at the ends, so the way you fill the bag matters as much as the bag itself. Slide biscuits in upright rather than dropping them from height, and leave enough headspace above the top biscuit for the zip to close without pressing down on it. Bags with a gusseted base open wider at the bottom, which makes filling quicker and reduces snapped corners.
When sealing, run the heat seal a few millimetres above the zip so customers can tear the notch cleanly and still use the closure. A short test run with your own sealer is worth doing before a big batch, because film thickness and sealer settings vary. If you post biscotti, a snug outer box with a little paper fill stops the pouch sliding around and keeps every biscuit whole.
Last of all, think about how your bags will be stored before they are filled. Keep unused pouches flat in their carton, away from direct sun and heat, so the zips stay aligned and the print does not scuff against other stock on the shelf. Pouches with a tear strip instead of a zip are sealed the same way; see our tear notch pouches for single servings.
Count Biscotti per Bag, Then Measure the Longest
Biscotti pouches are sized by the biscuit, not by weight alone. Decide how many pieces you want in a bag, lay them side by side as they will be packed, and measure the longest biscuit and the stack height. Add 30 mm at the top for the zip and seal and you have the pouch dimensions. Choose the finish next: a matt film with a window panel suits artisan bakeries, while a gloss film shows photography better. Artwork for a pouch is drawn on a flat template with the front, back and gussets marked, so send your logo as a vector file and the ingredients and allergen text as plain text and we will place it all on a free proof. The quote comes by email within one working day with prices from £0.25 a bag depending on size and film, and small first runs are quoted on their own terms. Production takes 4 to 7 working days once the proof is approved. Single-biscuit portions for cafés sit better in our flat mylar bags for single pieces.

Biscotti Mylar Bags Questions
What buyers ask before ordering biscotti mylar bags.
How do mylar bags keep biscotti crisp?
The layered film includes a barrier that blocks moisture and air, which is what softens biscotti. Once heat sealed, the bag protects the bake until it is opened. The zip then lets customers reclose it between servings.
Do I need to heat seal the bags?
Heat sealing above the zip gives the best protection and shows customers the bag has not been opened. A simple impulse sealer is enough for most bakers. You can use the zip alone for products sold the same day.
Can I have a window to show the biscotti?
Yes. A small shaped window shows the bake while keeping most of the barrier. If your biscotti need a long shelf life, keep the window small or choose a fully opaque bag.
Which size fits full-length almond biscotti?
Measure your longest biscuit and add room for the zip and seal at the top. Tall slim pouches suit traditional full-length biscotti. We suggest exact dimensions in your quote.
Can almond and pistachio biscotti share one pouch order?
Yes, as long as both flavours use the same pouch size. We print a different front panel for each flavour within one order and price the total together. Tell us the split between flavours when you ask for the quote.
Where do nut and gluten allergen warnings go on a biscotti pouch?
On the back panel, in a block beside the ingredients and weight, with the allergens in bold so they are easy to find. You supply the wording and we set it to a readable size on the proof. Leave a clear area if you add best-before dates by hand or sticker.
Can the bags go through a letterbox?
A flat pouch filled with a single layer of biscotti usually fits a standard letterbox. Stand-up pouches are better posted in a small box to protect the biscuits from breaking.
Which inner film suits dry baked biscotti?
The inside layer is a food-contact grade film chosen for dry baked goods, which keeps moisture out and oils from the nuts in. Tell us exactly what is going in the bag and we confirm the film in the quote. Softer, moister bakes may need a different structure.
Can I add best-before dates myself?
Yes. We can leave a blank panel on the back for a printed sticker or a handwritten date. This lets you use one print run across many batches.
What finish looks best for an artisan bakery?
A kraft-effect outer with simple dark print gives a handmade look, while matt film with an illustrated design feels modern and premium. The proof helps you compare the look before printing.
How soon can bags arrive for a market weekend?
After proof approval, production takes 4–7 working days and delivery to the UK mainland takes 2–3 working days, free and tracked. Ordering around two weeks ahead keeps you safe.
