Custom Kraft Mylar Bags: Flexible Packaging with Natural Appeal
For products that require an airtight, moisture-resistant barrier with the visual warmth of natural kraft, custom kraft mylar bags offer the best of both material worlds. The kraft exterior delivers the authentic, earthy aesthetic associated with artisan, organic, and clean-label brands, while the multi-layer mylar laminate inside creates a hermetic seal that protects products from oxygen, moisture, light, and odor. This combination makes kraft mylar bags one of the most versatile flexible packaging formats available, serving everything from specialty coffee and loose-leaf tea to CBD products, dried herbs, spice blends, and pet treats. Teal Packaging works with manufacturing partners experienced in flexible packaging production to deliver fully custom printed kraft mylar bags with free shipping to the US, Canada, UK, and Australia and a minimum order of 50 units.
Materials and GSM Specifications for Kraft Mylar Bags
The multi-layer construction of custom kraft mylar bags is what gives them their performance characteristics. Standard configurations include: For related packaging needs, explore our shipping boxes.
- Kraft / VMPET / PE (3-layer): The most common configuration. The outer kraft paper layer is typically 60 to 80 gsm, providing print surface and natural aesthetic. The middle vacuum-metallized PET (VMPET) layer creates the moisture and oxygen barrier. The inner food-grade polyethylene (PE) heat-seal layer enables the bag to be heat sealed securely.
- Kraft / VMPET / AL / PE (4-layer): Adds an aluminum foil layer for maximum barrier performance. Recommended for products with long shelf life requirements or high sensitivity to oxygen and light, such as premium coffee, CBD oils, and freeze-dried foods.
- Matte kraft exterior: A matte finish on the kraft outer layer reduces glare and gives a premium, tactile quality that is popular in specialty food and wellness categories.
Bag weights and thicknesses are specified by the manufacturing partners based on product type, weight, and required shelf life. Standard total laminate thicknesses range from approximately 100 to 150 microns depending on the configuration selected.

Sustainability in Kraft Mylar Bag Production
Kraft mylar bags are a composite material, and it is important to be transparent about their recyclability. Teal Packaging is committed to honesty on this topic:
- FSC-certified kraft outer layer: The kraft paper used for the outer surface is sourced from FSC-certified forests, ensuring responsible raw material sourcing.
- Soy-based inks: All printing on the kraft exterior uses soy-based inks, reducing the environmental impact of the print process.
- Recyclability note: Multi-layer laminate bags are not currently recyclable in standard curbside programs due to the bonded layers of different materials. Some specialist flexible packaging drop-off programs accept them. We are transparent about this trade-off: the barrier performance that protects product freshness and reduces food waste is the primary sustainability argument for kraft mylar bags.
- Mono-material alternatives: For brands that require curbside recyclability, we can discuss mono-material flexible packaging alternatives at the time of quote.

Frequently Asked Questions About Custom Kraft Mylar Bags
What products are best suited to kraft mylar bags?
these boxes are ideal for any product that benefits from moisture, oxygen, or light barrier protection while also benefiting from the visual character of kraft paper. Popular applications include specialty coffee, loose-leaf tea, dried herbs, spice blends, CBD products, pet treats, freeze-dried foods, and nutritional supplements.
Can I get a resealable zip closure on my kraft mylar bags?
Yes. Zip-lock resealable closures are one of the most popular options across all bag sizes. They allow consumers to open, use, and reseal the bag multiple times while maintaining product freshness. This is particularly important for coffee, tea, and snack products that are consumed over multiple sessions.
Do one-way degassing valves affect the barrier properties of the bag?
One-way degassing valves allow CO2 produced by freshly roasted coffee to escape while preventing oxygen from entering. When properly heat-bonded to the bag surface during production, they maintain the overall barrier integrity of the bag. They are a standard component in premium coffee packaging and do not compromise shelf life when correctly installed.
How do I determine the right bag size for my product?
Bag sizing depends on the fill weight and density of your product, as well as the fill level you prefer for shelf appearance. Share your product type, target fill weight, and any preferred bag dimensions when requesting your quote. Our team can recommend the appropriate size and style based on common fill volumes for similar products.
Can I print on both sides of the kraft mylar bag?
Yes. Full-color printing is available on the front and back panels of stand-up pouches, and on the side gusset panels for larger bags where additional surface area is available. Many brands use the back panel for product information, ingredient lists, and usage instructions, while the front carries the primary brand design.
