Custom Stand-Up Mylar Bags

Custom Stand-Up Mylar Bags Built to Sell and Protect

A stand-up mylar bag does two jobs at once. On the outside it is a printed billboard for your brand, with a front and back panel big enough for a logo, product name, flavor story and nutrition or ingredient panel. On the inside it is a sealed barrier that keeps oxygen, moisture, light and odor away from what you have packed. That combination is why stand-up pouches have replaced jars, tins and folding cartons for so many food, wellness and retail brands.

Mailer Boxes Co prints custom stand-up mylar bags for coffee roasters, snack makers, supplement companies, candy shops, pet treat bakers and dozens of other businesses across the US. You choose the size, film, finish and closure, we print your artwork edge to edge and the bags arrive flat, ready to fill and seal on your line or by hand.

How a Stand-Up Pouch Is Built

The pouch is made from two or three layers of film bonded together. The outer layer is printable PET (polyester) that carries your artwork and gives the bag its gloss, matte or soft-touch feel. The middle layer is the barrier: metallized PET for everyday products, or aluminum foil when you need the strongest protection against oxygen and light. The inner layer is food-grade polyethylene, which is the only part that touches your product and the part that melts to form airtight heat seals.

A folded gusset at the base opens when the bag is filled. That gusset is what lets the pouch stand upright on a shelf, a café counter or a market table, and it is also why a stand-up pouch holds more than a flat bag of the same width and height.

Options You Can Choose

• Finish: matte, gloss, soft-touch matte, metallic or holographic film, with spot gloss over a matte bag to make a logo stand out.
• Closure: a press-to-close zipper for everyday resealing, or a child-resistant zipper where regulations require one.
• Tear notches above the zipper so customers can open the bag cleanly without scissors.
• Clear window in any shape so shoppers can see the product before they buy.
• Hang hole (round or sombrero style) for peg displays in retail stores.
• Rounded corners for a softer, premium look and to stop sharp corners from puncturing other bags in a shipment.

Who Orders Custom Stand-Up Pouches

Most of our stand-up orders come from brands selling dry goods by weight. Coffee roasters often start here before moving to flat bottom coffee bags for larger sizes. Snack brands use them for chips, nuts and trail mix, and candy makers pair them with a window to show off color. Supplement companies use larger sizes for powders and smaller sizes for capsules and gummies, often with a child-resistant zipper.

If your product needs to be seen, take a look at our window mylar bags. If you need a bag that is hard for children to open, see child-resistant mylar bags.

Choosing the Right Size

Fill weight depends on how dense your product is, so two products of the same weight can need different bag sizes. A 5 × 8 × 3 inch pouch is the most popular size and usually holds 3–4 oz of coffee beans, snacks or gummies. Lighter, bulkier products such as popcorn or loose-leaf tea need a bigger bag for the same weight, while dense powders and bath salts fit in a smaller one. The size guide on this page lists our standard sizes, and every bag can also be made to a custom width, height and gusset.

Preparing Artwork for a Stand-Up Pouch

We send you a dieline: a flat template showing the front, back, gusset, seal areas and where the zipper and tear notch sit. Keep logos and text at least a quarter inch inside the seals, because the outer edges are pressed flat when the bag is sealed. Barcodes work best on the back panel, printed dark on a light background so scanners read them reliably.

If you are printing on metallized film, remember that anything without white ink underneath will look metallic. That can be a striking effect for a logo, but plan it on purpose. Our design team checks every file before proofing and will point out anything that may not print as you expect.

Filling and Sealing

Pouches arrive with the top open and the zipper already in place. Fill through the top, then heat seal above the zipper with a band sealer or impulse sealer. The tear notch sits between that seal and the zipper, so your customer tears off the top and uses the zipper from then on. If you fill by hand, an inexpensive impulse sealer is all you need to get started.

Questions Customers Ask

How thick should my pouch be?

Most products are well protected by 3.5–4.5 mil film. Choose 5.5 mil for heavy fills over a pound, sharp products such as nuts in shells, or bags that will be shipped loose without a box.

Can you match my brand colors?

Yes. Send your Pantone or CMYK values and we will match them as closely as the film allows. Metallized films shift colors slightly, which your proof will show.

Do pouches come with zippers already fitted?

Yes. Zippers, tear notches, hang holes and valves are all added during production, so the bags arrive ready to fill and seal.
