Description
Overview

Kraft Mylar Bags

A paper face over a barrier laminate — natural on the outside, engineered behind it.

Kraft carries the positioning while the film behind it does the moisture and aroma work. The trade-off is print: brown board shifts every colour laid on it.

The Library

Every surface, hand-selected.

What this product is built from, and the surfaces it takes. Below the build sheet, the full swatch library — every option applies across our range, and a physical swatch set is available on request.

Material
Kraft / PE
Paper outer over a polyethylene liner. Basic moisture barrier, good for dry goods with modest shelf-life.
Standard
Kraft / AL / PE
Paper outer with an aluminium foil layer behind it. Natural look, coffee-grade barrier.
High barrier
White Kraft
Bleached kraft for a paler base where colour reproduction matters more than the raw look.
Better colour
Recycled Kraft
Post-consumer content paper outer. Slightly more variable in tone, which some brands want.
Eco positioning
PE Liner
The sealant layer. It is what actually touches your product and forms the heat seal.
Contact layer
Finish
Uncoated Kraft
Raw paper surface, matte and tactile. The most honest expression of the material.
Most natural
Matte Lamination
Thin protective film over the paper. Keeps most of the texture, resists scuffing better.
Protective
Hot Foil Stamping
Metallic on brown kraft is the highest-contrast option available on this substrate.
Best contrast
Spot Gloss
Gloss varnish over matte kraft — visible as sheen against the paper.
Subtle
White Underprint
A white base laid under colour so it reads true rather than mixing with the brown.
Colour accuracy
Clear Window
Die-cut panel with film behind, showing product against the paper.

What We Make

The full kit of capabilities.

Kraft Paper Outer
Unbleached, white or recycled-content kraft as the visible surface.
Foil Liner Option
Aluminium layer behind the paper for coffee-grade barrier.
Clear Window
Die-cut panel showing the product against the kraft.
Degassing Valve
One-way valve for fresh-roast coffee.
Hot Foil Stamping
Highest-contrast decoration available on a brown substrate.
White Underprint
Base layer so colours read true rather than mixing with the paper tone.
Press-to-Close Zipper
Full-width resealable closure.
Tin Tie Closure
Fold-and-tie strip, common on coffee and bakery bags.
Tear Notch
Opens by hand above the closure.
Photographic Print
Brown kraft shifts every colour laid on it. Full-colour photography will not reproduce accurately — design for one or two colours plus foil.
Kerbside Recyclable
The paper is bonded to a film liner, so it is not a paper-stream item despite how it looks.

Sizing & dieline.

Every Kraft Mylar Bags is made to your fill, not pulled off a shelf. A pouch is quoted width × length, plus the gusset that lets it stand — tell us what goes inside and how much of it, and we return a measured spec, free, before you commit to anything.

How to measure
01
Start with the fill

A pouch is sized by what goes in it, not by outside dimensions. Give us the fill weight and, if you can, the bulk — 500 g of granola needs far more bag than 500 g of powder.

02
Width and length

We quote width × length, then the bottom gusset depth that sets the footprint. Three figures, and the gusset is the one most often left off.

03
Say what it must do

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.

What It Costs

Pricing & minimums.

Kraft Mylar Bags is priced per specification rather than from a fixed list — the same box 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.

What moves the price
Quantity

The single biggest lever. Unit cost falls sharply as volume rises, because setup and tooling spread across more pieces.

Material and thickness

Board weight and stock choice change both the raw material cost and the shipping weight of the finished run.

Finishing

Foil, spot UV, embossing and soft-touch each add a pass on press. One or two lift the box; five compound the cost.

Print coverage

Full-bleed print inside and out costs more than a one-sided design on natural stock.

Inserts and hardware

Foam, moulded pulp, velvet pillows, magnets and ribbon are priced per piece on top of the box itself.

Timeline

Standard production is the base rate. Rush moves you up the production queue and carries a surcharge.

— Frequently Asked Questions —

Questions, answered.

Everything you need to know about Kraft Mylar Bags.

Mylar (BoPET) film provides oxygen, moisture, and UV barrier performance significantly superior to standard poly bags. The multi-layer construction combines different film types for optimal barrier balance. For products where shelf life and potency preservation are critical — specialty food, cannabis, supplements, botanicals — the performance difference between mylar and standard packaging is directly measurable in product quality over time.
Heat sealing creates an airtight, permanent seal across the bag opening. Impulse heat sealers are the standard for small-to-mid volume operations. For maximum shelf life on dry products, combining heat sealing with oxygen absorbers removes residual oxygen inside the bag. Resealable zipper versions use press-to-close mechanisms for products used across multiple sessions.
Yes — food-contact mylar films meet FDA food contact material standards. Inks used in food-compliant mylar printing are food-safe. For products where food safety documentation is required by retail buyers or regulatory compliance, PackTist can provide food contact compliance certifications for the materials used.
