Custom Cookie Mylar Bags

Sizing Cookie Mylar Bags Properly

Measure the diameter of your largest cookie and its thickness. For a single cookie in a flat pouch, add around 20 mm to the width for easy filling, and allow for the zip and heat seal at the top, which take up about 30 to 40 mm of the bag height. For a stack, measure the stack height and choose a stand-up pouch whose gusset opens to at least that depth.

Do not size too tightly. A cookie squeezed into a snug pouch will crack as it goes in, and crumbs in the zip stop it closing properly. If in doubt, order a few plain samples in two sizes and try them with real cookies before committing to printed bags.

Weight is the other measure worth noting. If you sell cookie bites by weight, fill a sample bag with the target weight and check the fill line sits well below the zip. A bag that is too full is hard to close and tends to split along the side seals when squeezed. Our steps for measuring a cookie stack show where the seal allowance goes.

Sealing for Freshness and Tamper Evidence

Most cookie bags combine two closures. The heat seal at the very top is applied after filling with a simple impulse sealer, and it shows clearly whether the bag has been opened. Below it sits the press-to-close zip, which the customer uses after tearing the top off at the notch. This gives you a tamper-evident first opening and a resealable bag for the rest of the week.

If you sell at markets and fill bags just before the stall opens, a zip alone may be enough. For anything posted or sold through a shop, we strongly recommend heat sealing. It costs little and stops customers worrying that a bag has been tampered with. Single cookies sold at a till are often packed in tear notch pouches for single cookies instead.

Print, Windows and Finishes

Mylar is printed digitally for shorter runs and by rotogravure for very large runs, so both small bakeries and bigger brands can have full-colour bags. Matt surfaces look modern and calm and hide fingerprints. Gloss looks bright and lively and suits bold, colourful brands. A spot gloss on a matt bag, applied only to the logo or cookie photo, adds contrast that catches the eye.

A clear window shows the real cookie, which is persuasive if your bake looks good. Keep the window large enough to show the texture but not so large that it weakens the barrier. Windows let in light, which can affect chocolate over a long shelf life, so think about how long your bags will sit on display.

Inside printing is possible on some bag types and makes a fun surprise: a thank-you message or a reheating tip revealed as the customer tears the bag open. It adds a little cost, so it suits brands that already lean heavily on unboxing. A larger clear panel is available on our window mylar bags showing the cookie.

• Front: logo, flavour and a clear window or photo
• Back: ingredients, allergens, weight and storage notes
• Gusset: a pattern or brand colour visible on the shelf
• Top strip: space for a best-before sticker or stamp

Who Buys Printed Cookie Bags

Online bakeries posting cookie boxes use mylar bags inside a shipping box so each cookie stays fresh even if the box sits for a day. Cafés use window pouches by the till for impulse buys. Farm shops and delis stock bagged cookies from local bakers, and wholesale bakeries supply them to coffee chains, gyms and offices. Event caterers use small pouches as favours, often with a custom flavour or message printed for the occasion.

Brands that sell cookie dough or cookie mixes use the same bags, sometimes with a larger gusset and a zip for repeated use.

Bakers moving from boxes to bags often keep both: a printed mailer box for the outside journey and individual mylar bags inside it. The box carries the brand on arrival, and the bags keep each cookie at its best while the customer works through them over a few days.

Bag a Cookie and Leave It on the Counter Overnight

The honest test of a cookie bag is a day old cookie, so before you order, seal one of yours in any barrier pouch and try it the next morning. If it is still soft, a zip and a heat seal is the right spec; if it dried out, you need a thicker film. Then measure the cookie at its widest and the height of the stack you want in each bag, and add 30 mm for the seal and zip. Choose stand-up or flat by how the bags are sold: stand-up for shelves, flat for mailing. Artwork goes on a flat template with front, back and gusset marked, so send a vector logo and the allergen text as plain text and we set it on a free proof. The quote comes by email within one working day, minimums are low and quoted per job, and bags are made in 4–7 working days after approval with free tracked UK mainland delivery. Firmer bakes that need to stay crisp rather than soft use our biscotti bags for crunchier bakes.
