Custom Flat Mylar Bags

Custom Flat Mylar Bags for Samples, Single Servings and Retail Pegs

Flat mylar bags are the simplest pouch we make and often the smartest. They are sealed on three sides and filled from the top, so they stay slim, stack neatly and cost less per bag than any other style. When your product is small, light or sold in single portions, a flat bag protects it just as well as a larger pouch without paying for film you do not need.

We print custom flat mylar bags for sample programs, subscription boxes, seed companies, spice blenders, accessory brands and dispensaries. Each bag is printed in full color on both faces, so one side can sell the product and the other can carry directions, ingredients and a barcode.

Where Flat Pouches Work Best

• Samples and trial sizes that go into subscription boxes, mailers or retail checkout bins.
• Single servings of coffee, tea, protein, electrolytes or snacks.
• Seed packets, spices and dried herbs sold on retail pegs.
• Small accessories such as patches, stickers, jewelry and spare parts.
• Exit packaging for dispensaries; see our dedicated custom exit bags for child-resistant versions.

Construction and Barrier

Flat bags use the same laminated film as our stand-up pouches: a printable PET outer, a metallized or foil barrier, and a food-grade PE inner layer that forms the seals. That means a 3 × 4 inch sample sachet keeps coffee, tea or supplements as fresh as a full-size bag. For products that need to be seen, we can leave a clear area in the film or cut a window.

Closures and Finishing

Add a press-to-close zipper when the bag will be opened more than once, or keep a clean heat seal with tear notches for one-time use. A hang hole lets the pouch sit on a peg, and rounded corners give a softer finish. If you want a pouch shaped like your product or logo, see die-cut mylar bags.

Matte, gloss and soft-touch finishes are all available, and holographic film turns even a small sample sachet into something people keep. See holographic mylar bags for ideas.

Flat or Stand-Up?

If your fill is under about 1 oz or the bag will hang on a peg, a flat bag is usually the better buy. If the bag needs to stand on a shelf or hold more than a couple of ounces, choose stand-up mylar bags. Many brands use both: a stand-up pouch for the full-size product and a flat sample sachet of the same design for giveaways.

Planning a Sample Program

Sample sachets are some of the hardest-working packaging a brand can buy. A good sample bag uses the same colors and logo as your full-size product, so the customer recognizes it in the store later. Add a QR code or short URL to the back that leads to a discount on the full-size bag, and you can track exactly how many samples turn into sales.

Because flat bags use less film, they are also the cheapest way to test a new flavor or blend before you commit to a large run of a full-size pouch.

Filling Flat Bags

Flat pouches are filled from the open top and heat sealed, either with an impulse sealer for small runs or on an automatic filling line. Leave enough headspace above the product for a clean seal, which is usually half an inch or more depending on the bag size. If the bag has a zipper, the seal goes above it, with the tear notch in between.

Questions Customers Ask

How small can a flat bag be?

We regularly make flat bags from 3 × 4 inches, and smaller sachets on request for single doses and samples.

Can both sides have different designs?

Yes. Front and back are printed separately, so one side can carry branding and the other directions, ingredients or a QR code.

Are flat bags good for mailing?

Yes. They are light and slim, so they fit inside envelopes, subscription boxes and mailers without adding much weight.
