What Is Mylar Packaging?

Mylar packaging refers to flexible packages made from biaxially oriented polyethylene terephthalate (BoPET), a polyester film prized for its strength, clarity, and barrier performance. If you’ve ever wondered “what is Mylar” or “what is a Mylar bag,” this is the foundation: a high-performance polyester film often laminated for added protection.

These mechanical and barrier characteristics are well-documented in academic research. A review titled Polyethylene terephthalate (PET) in the packaging industry on ScienceDirect outlines how biaxial orientation enhances PET’s tensile strength, dimensional stability, and gas barrier properties key reasons it forms the base of modern Mylar packaging films.

In many applications, Mylar is laminated with other layers such as aluminum foil for light blocking or polyethylene for sealability to improve resistance to oxygen, moisture, and punctures. This multi-layer structure enables Packaging Studio to supply bags, pouches, and rollstock that safeguard aroma, freshness, and product integrity across categories including snacks, coffee, supplements, and sensitive dry goods.

Mylar emerged in the 1950s with advances in polyester chemistry and film orientation. By stretching the film in two directions, manufacturers aligned polymer chains, which improved tensile strength, dimensional stability, and barrier properties.
