Child-Resistant Mylar Bags
A barrier pouch with a zipper only adults can work, press-to-close plus a slider lock.
The CR mechanism sits on top of the barrier structure, so the bag has to seal against oxygen and against small hands at the same time.

Every detail. Intentional.
Two jobs, one closure
Barrier seal and CR lock.
Press-and-slide zippers
The certified mechanism here.
Foil laminate underneath
Barrier is still the base spec.
Reclosed hundreds of times
Zipper fatigue is the risk.
Panel-tested to the CR standard
Child and adult panels both.
Opening instructions printed
On the front, not the back.
Built like architecture.

Sizing & dieline.
Every Child-Resistant Mylar Bags is made to your fill, not pulled off a shelf. A pouch is quoted width × length. Tell us what goes inside and how much of it, and we return a measured spec, free, before you commit to anything.
A pouch is sized by what goes in it, not by outside dimensions. Give us the fill weight and, if you can, the bulk, since 500 g of granola needs far more bag than 500 g of powder.
We quote width × length. Flat pouches need no gusset figure, because the bag lies flat when empty.
Zipper or heat seal only, valve or no valve, window or full barrier. These change the film and the bag height, so they belong in the spec rather than added afterwards.
✦ Not sure of your size? Send us the product and we measure it and build the dieline.
Pricing & minimums.
We price Child-Resistant Mylar Bags per specification rather than from a fixed list, because the same build in two different finishes can land at very different numbers. Below is what actually moves the price, so you can shape the spec before you request a quote.
The single biggest lever. Unit cost falls sharply as volume rises, because setup and tooling spread across more pieces.
Board weight and stock choice change both the raw material cost and the shipping weight of the finished run.
Foil, spot UV, embossing and soft-touch each add a pass on press. One or two lift the box; five compound the cost.
Full-bleed print inside and out costs more than a one-sided design on natural stock.
Foam, moulded pulp, velvet pillows, magnets and ribbon are priced per piece on top of the box itself.
Standard production is the base rate. Rush moves you up the production queue and carries a surcharge.

Questions, answered.
Everything you need to know about Child-Resistant Mylar Bags.
It takes two deliberate actions, either press-and-pull or align-and-squeeze, before the track separates. A child tugging at the top gets nowhere, while an adult who reads the printed instruction opens it without trouble.
A tear notch above the zipper handles the first opening. After that the bag is reclosed on the zipper every time, and it has to relock to the certified standard after each use.
A typical build is a PET outer, a foil or metallised middle and a PE sealant inside. The PET takes the print, the foil layer blocks moisture and oxygen and hides the contents, and the PE lets us heat seal the edges.
Smell-proofing comes from the laminate structure, so the barrier layers you pick decide how well the bag holds odour. A kraft paper outer is available for a natural finish.
No, the certification covers the zipper and the film together, so a new film needs new testing. A certified zipper sealed into a different laminate doesn't carry the rating across on its own, which is a common misunderstanding.
If you want a cheaper or recyclable film later, plan it as a new certified build. Check zipper track alignment on every sample, since a misaligned track can defeat the lock.
We print full-coverage CMYK across both faces, finished in matte, gloss or metallic. Matte film is the usual dispensary choice and holds fine type well. Metallic film shows through any unprinted areas as a bright foil effect.
These bags are opaque, with no window patch. Opening instructions go near the zipper on the front, where a first-time buyer will see them.
Common flat sizes are 3.5 × 5 in, 4 × 6 in and 6 × 9 in, measured width by height. These are flat pouches without a stand-up gusset, so they lie flat in a drawer or hang from a peg by the hang hole.
The zipper and tear notch take up headroom at the top. We work out the usable fill area for you and can make custom sizes to suit your count.
The run starts at 500 bags per design and size. Each bag carries the same certified zipper and film pairing, so there's no smaller untested version.
Brands with several strains or flavours often order 500 of each printed design. Quantities scale to 100,000 bags on the same laminate and zipper.
Expect 7 to 10 business days from approved proof, or 5 to 7 when you need them on a rush. Samples arrive within 5 to 7 business days, and that's the moment to check the zipper track sits true and the tear notch lines up.
The cost of that sample bag is set against your production order. Design help is free and we ship mylar orders across the USA.
Recyclable mono-material films are coming into this category, but check the CR status of any specific build before you switch. Most certified bags still use a mixed laminate of PET, foil and PE, which curbside programs don't take.
If recyclability is the priority, ask us which mono-material builds have been tested with a CR zipper. A kraft paper outer changes the look but not the laminate underneath.
