What Are Custom Mylar Bags?
custom mylar bags are flexible, multi-layer pouches manufactured to your exact size, print, and barrier specification, rather than pulled from a limited stock range. Because the barrier film blocks moisture, oxygen, and light, the pouches extend shelf life for products such as coffee, jerky, pet treats, dried goods, and small-batch retail items. For food brands, dispensaries, and e-commerce sellers ordering wholesale, the pouch does two jobs at once: it protects the product, and it functions as a printed surface for your branding at the point of sale. That combination is why mylar has become the default flexible packaging format across food, wellness, and cannabis retail over the last decade.
How the Barrier Film Is Built
A standard custom mylar bags is not a single material — it is a laminate of three functional layers. The outer layer carries your print and finish (matte, gloss, or soft-touch). Beneath it sits the barrier layer, typically a metalized PET or foil film — this is what stops light and oxygen from reaching the product. The innermost layer is a heat-seal poly film that forms the actual seal around your product. Our standard barrier stock is a [INSERT MATERIAL SPEC — e.g., 3-layer metalized PET/PE laminate, X microns], which we can confirm against a technical data sheet on request. Where a specific certification applies to the material, such as e.g., food-contact compliance under AS 2070 or an equivalent FDA-aligned standard], we will list it once confirmed rather than assume it applies to every run.
Custom vs. Generic Stock Mylar Bags
Generic stock mylar bags come in a handful of fixed sizes with plain or minimally printed faces. Consequently, brands either end up with wasted headspace above the product or a label sticker covering most of the artwork. A custom mylar bag, in contrast, is sized to the actual fill volume and printed full-surface in your brand colors, which removes both problems in one step. Because the pouch dimensions are built around your product rather than the other way around, you also cut down on void fill and freight volume, since the bag isn't oversized for what's inside it.
Material Options and Barrier Specifications

Best Use Case |
Notes |
|
Metalized PET/Foil Laminate |
High — blocks light, oxygen, moisture |
Coffee, jerky, long-shelf-life snacks |
Highest opacity; standard for cannabis/dispensary compliance |
|
Clear PET Laminate (window) |
Medium — moisture resistant, light-permeable |
Products where visual display matters |
Often paired with a printed back panel for partial coverage |
|
Kraft Paper Mylar Laminate |
Medium — depends on inner film thickness |
Coffee, tea, granola, artisan-positioned snack brands |
See dedicated section below |
|
Matte Poly Laminate |
Medium-high |
General retail, subscription boxes, supplements |
Lower cost than foil laminate; softer print finish |
Material choice drives both shelf life and shelf appeal, so it's worth treating as a spec decision rather than a finish preference.
Kraft Mylar Bags: The Paper-Look Option With a Barrier Core
kraft mylar bags pair an outer layer of kraft paper — the natural brown or white kraft look associated with eco and artisan branding — with an inner barrier laminate that does the actual protective work. This matters because kraft paper alone has almost no moisture or oxygen barrier. Therefore, a genuine kraft mylar bag is still a laminate: kraft face, then a thin metalized or PE barrier film bonded underneath, then the heat-seal layer. The result looks and feels like a paper bag on the outside while performing like a standard mylar pouch on the inside.
Coffee roasters, tea brands, and small-batch snack producers tend to choose kraft mylar bags specifically because the material signals "craft-market" or sustainable positioning without giving up barrier performance. That said, we'd rather flag this than let it slide: a kraft-laminate pouch is generally not kerbside-recyclable in the same stream as plain paper, because the barrier layer is bonded to the kraft face. If recyclability or compostability is a claim you want on the page, we need confirmed against the specific film stock before it goes live — this is exactly the kind of claim that gets brands in trouble if it's asserted without backing.

Closure Options
Most orders ship with a resealable zipper, since it lets the end customer reopen and reclose the bag without breaking the barrier seal. For products that don't need reopening, a straight heat seal keeps costs down and simplifies the packaging line. Where regulation requires it — dispensary and cannabis orders in particular — we also produce child-resistant zipper closures tested against, and we'll confirm the applicable AU state requirement before quoting a run in that category.

Manufacturing Process and Quality Control
Every custom mylar bag order moves through the same checkpoints before it reaches your dock, because barrier performance and seal integrity are the two things that actually determine whether the product survives transit and shelf time.
Material Sourcing and Testing
Film stock is ordered against a specification sheet rather than a general description, and incoming rolls are checked before they go into production. Where a specific certification is confirmed for a given material batch, we'll attach it directly — for example rather than apply a blanket claim across every product line.
Print, Seal, and Sample Approval
Before a bulk run starts, we produce a pre-production sample from your actual artwork file, so you're approving the real print and seal quality rather than a mockup. During production, seal strength is spot-checked at intervals, since a weak seal is the most common cause of barrier failure in flexible pouches. If a batch doesn't hold seal integrity within tolerance, it's held back rather than shipped — that's a process claim, not a marketing line, and it's the standard we'd expect any packaging manufacturer to hold itself to.
How to Order Custom Mylar Bags
1. Send your specs. Product type, fill weight, and preferred bag style — or talk to our packaging design team if you're starting from scratch.
2. Review your proof. You'll see a digital proof first, followed by a physical pre-production sample for sign-off.
3. Approve and confirm quantity. Wholesale pricing breaks apply at set volume tiers — we'll show you where the next break sits.
4. Production and QC. Your run goes through the seal and print checks outlined above before packing.
5. Delivery. [INSERT CONFIRMED FREIGHT TERMS — e.g., free AU-wide freight over $X, standard turnaround in business days].
Common Questions About Custom Mylar Bags
What is a custom mylar bag?
A custom mylar bag is a flexible, multi-layer pouch manufactured to a specific size and barrier specification, with full-surface custom printing, rather than selected from a fixed stock size range.
Are custom mylar bags food-safe?
Bags made with food-grade barrier film are suitable for direct food contact. However, the specific certification depends on the material batch, so we confirm DODO Packaging AU against your product category rather than applying it universally.
What's the difference between kraft mylar bags and standard mylar bags?
kraft mylar bags use an outer kraft paper face bonded to an inner barrier laminate, giving a paper-look exterior with mylar-level protection underneath. Standard mylar bags use a metalized or clear PET face instead, generally at a lower cost per unit.
Is there a minimum order quantity?
This depends on bag style and print complexity, so it's worth confirming per style rather than quoting a single blanket number.
Do custom mylar bags come with child-resistant closures? Yes, for categories that require it — cannabis and dispensary orders in particular — we produce child-resistant zipper closures tested against [INSERT COMPLIANCE STANDARD].
