Custom Kraft Mylar Bags

Description

Custom Kraft Mylar Bags: Sustainable Barrier Packaging That Extends Shelf Life. 

Custom kraft mylar bags combine a natural kraft paper exterior with an interior mylar barrier film. The kraft outer surface communicates natural, sustainable, and artisan brand values. The inner mylar layer provides the moisture, oxygen, and light barrier performance your product needs.

Packaging Ship manufactures custom kraft mylar bags for food, coffee, cannabis, and supplement brands across the US. Kraft mylar bags are not a compromise between aesthetics and performance. They are a format where both operate simultaneously, when the structure is built correctly.

The Tension That Kraft Mylar Resolves

Most brands face a packaging conflict. Consumers want sustainable, natural-looking packaging. Products require high-barrier protection to maintain freshness, potency, and shelf life. These two requirements seem to pull in opposite directions.

Standard mylar bags use a metallic exterior. They perform well. However, they look industrial. They signal barrier protection, not natural origin or ethical sourcing.

Standard kraft paper bags look natural. They perform poorly as moisture and oxygen barriers. A kraft paper bag without an interior barrier layer allows moisture ingress within days in humid environments.

Kraft mylar resolves this conflict directly. The kraft exterior delivers the natural, sustainable visual language. The laminated interior mylar film delivers the barrier performance. Furthermore, the kraft surface accepts print differently from standard mylar, ink reads warmer, colors sit softer, and the textural surface creates a tactile quality that metallic mylar cannot replicate.

What Kraft Mylar Is Made Of Film Structure

A kraft mylar bag consists of three bonded layers.

• The kraft outer layer is natural, brown, unbleached paper stock ranging from 30 to 120 GSM depending on bag size and product weight. It is the print surface, the tactile surface, and the visual face of the bag. White kraft and bleached kraft variants are available for brands that want a cleaner print surface while retaining the natural brand positioning.
• The barrier middle layer is a metalized PET or aluminum foil laminate. This layer blocks moisture vapor, oxygen, and UV light from penetrating through to the product. The barrier specification determines shelf life, a higher barrier rating is selected for sensitive products like cannabis, specialty coffee, and organic supplements.
• The inner sealing layer is food-grade PE (polyethylene). It bonds under heat to create sealed edges. It is the food-contact surface and determines seal integrity.
