Large mylar bags are oversized foil-laminate pouches built for fills that a standard snack-size pouch cannot hold, usually a pound or more of product. TBPB prints them custom with no minimum order, and if you bring a written quote for the same specs, we will beat it.
Why size changes the build
A bag that holds an ounce of product and a bag that holds five pounds are not the same bag scaled up. Weight pulls on the side seals and, on a stand-up pouch, on the bottom gusset. That is where large bags fail: a seal that looked fine at filling splits when a pallet is stacked or a customer drops the bag on a counter. When we quote a large format we talk about the fill weight first, then pick the film thickness and bottom construction to match it.
Thicker laminate also stands up better on a shelf. A floppy bag slumps and hides your print. A properly specified one holds its shoulders and keeps the front panel flat for the label area.
Formats we print for bulk fills
Most large orders land in one of three styles. A stand-up pouch with a bottom gusset sits on a retail shelf and suits one to five pound consumer packs. A flat or wicketed bag works well when you fill on a machine or by hand into a bin and heat seal across the top. A side-gusseted bag packs flat in a carton and is the usual choice for coffee. If your product is a smaller retail unit, look at our small mylar bags instead, and if the shelf look is the priority over capacity, the standard stand-up mylar bags cover the in-between sizes.
- Stand-up with bottom gusset, for retail shelves
- Flat or wicket style, for hand or machine filling
- Side-gusseted bulk bags, for coffee and dry goods
- Press-to-close zipper, tear notch and hang hole where the fill allows
- One-way degassing valve for freshly roasted coffee
- Matte or gloss finish, full-colour print, Pantone matching
Barrier, zippers and the details people forget
Foil laminate blocks light, and it slows oxygen and moisture getting in, which is why it is used for coffee, powders and dry pet food. It is not a guarantee of shelf life. Shelf life depends on your product, how dry it is when sealed, and how well the seal is made. If you are packing coffee, add a degassing valve, otherwise the bag inflates as the beans release gas. If you are packing a powder, check that the zipper track will not clog with dust, because a zipper that will not close is a real annoyance on a bulk bag.
Size the bag by volume, not by what the label says. Dense products like sugar or rice fill a bag differently from light ones like granola. Send us a sample of the fill, or the fill weight and its bulk density if you know it, and we will suggest a bag size with headspace left for sealing. Plan for roughly a couple of inches of unfilled top so the seal lands on clean film rather than on product.
When a large bag is the wrong answer
If your product ships to customers in cartons and you only need the pouch to protect it inside, a plain unprinted liner is cheaper than a printed one. If the product is a fragile item, a pouch will not protect it and a box will; our mailer boxes are the better outer pack. Food, supplement and cannabis labelling rules are your responsibility and vary by state, so confirm contact-material and labelling needs with your own regulatory adviser. We print the artwork you supply.
To get a quote, send the fill weight or the finished bag dimensions, the quantity, even if it is one, and your artwork or a rough idea. We set up the template and quote it. Browse the rest of the mylar bag range if you are still choosing a style.
Frequently asked questions
What is the minimum order for custom large mylar bags?
There is no minimum order at TBPB. You can order one bag as a sample, a few hundred for a launch, or tens of thousands for distribution. Each run is printed to your artwork and quoted on its own specs, and our price-beat guarantee applies to a written quote for the same specification.
What size is a large mylar bag?
There is no single standard. Retail stand-up pouches commonly run from one pound to five pounds of product, while bulk bags go larger. The right dimensions depend on fill weight and how dense the product is, so send us your weight and product type and we will recommend width, height and gusset depth.
Can large mylar bags hold coffee?
Yes. Freshly roasted coffee releases gas, so we recommend a one-way degassing valve on the bag. Side-gusseted and stand-up formats are both common for coffee. Foil laminate keeps out light and slows oxygen, but freshness still depends on roast date and how well the bag is sealed.
Are large mylar bags strong enough for heavy fills?
They can be if specified for it. Heavy fills stress the side seals and the bottom gusset, so we match film thickness and bottom construction to your fill weight. Tell us the weight and how the bag will be handled, and we will say honestly if a different format suits it better.
Can you add a zipper, valve or hang hole?
Yes. A press-to-close zipper, tear notch, hang hole and degassing valve can be added where the format allows. Zippers work best when the top is kept clean of powder, so tell us about your product when you request the quote, and we will advise which closures are practical.
Can I print my own artwork on large mylar bags?
Yes. We print your artwork in full colour, with Pantone matching available, on matte or gloss film. Send a vector file if you have one, or tell us what you have in mind. We draw the template to your bag size so you can see exactly where seals and zippers fall.
