Mylar bags are flexible pouches commonly made with polyester film and other barrier layers. A typical structure may combine BoPET, aluminum foil or metallized film, and polyethylene to provide strength, barrier protection, and heat sealing. High-barrier multilayer structures help reduce the transmission of oxygen, moisture, light, and aromas.
Mylar packaging was estimated to be worth $10.7 billion globally in 2021. This market is predicted to grow from $10.7 billion to $20.4 billion by 2031 at an annual growth rate of 6.9%. Many companies in the coffee, food, and retail segments are increasingly switching from rigid packaging to flexible packaging. Single-layer films may not provide the barrier performance required for products that are sensitive to oxygen, moisture, light, or odors. Multilayer structures allow different films to combine specific barrier and sealing properties.
At The Box Packaging, we manufacture custom Mylar bags according to your exact product dimensions. We use multilayer film structures selected for the product's required oxygen, moisture, light, aroma, and sealing performance. Our bag structures are engineered to provide strong seals and resistance to tearing, punctures, and handling stresses. You can also customize your bags with a window, a metallic effect, a child-resistant zipper, and a one-way degassing valve.

Mylar bags use multilayer film structures that combine different materials for specific packaging requirements. Each layer can contribute to barrier protection, strength, printability, heat sealing, or product presentation. The final structure depends on the product, required shelf life, filling process, and packaging application.
BoPET Film
Biaxially oriented polyethylene terephthalate (BoPET) provides strength, dimensional stability, and a smooth surface for high-quality printing. It also contributes to the overall barrier performance of multilayer pouch structures.
Aluminum Foil
Aluminum foil provides a high barrier against light, oxygen, moisture, and aroma transmission. It is commonly used in high-barrier packaging where protection from external conditions is important.
Polyethylene Sealant Film
Polyethylene is commonly used as the inner sealant layer in flexible packaging. It provides heat-sealing properties and helps create strong, reliable package seals. For food applications, the specific resin and complete packaging structure should be suitable for the intended food-contact use.
Metallized Film
Metallized films use a thin metal coating, typically aluminum, to improve barrier performance while providing a reflective appearance. They are often used when brands want a metallic look without using a full aluminum-foil laminate.
Kraft Paper
Kraft paper can be laminated with plastic or barrier films to create a natural paper appearance while maintaining the functional properties of the underlying packaging structure. The laminate is selected according to the required barrier, strength, and sealing performance.

These dimensions are examples rather than universal industry standards. We can adjust the bag length, width, gusset, and seal area according to your product and packaging requirements.
Create mylar bags with logo designs that showcase your brand name, product information, graphics, and colors. We select the printing process based on your film structure, artwork, order volume, and required print quality. Choose from digital, flexographic, or rotogravure printing based on your packaging needs.
Digital Printing
Digital printing works well for short runs, variable artwork, and designs with detailed full-color graphics. It does not require traditional printing plates, making it suitable for projects that need faster setup and flexible artwork changes.
Flexographic Printing
Flexographic printing uses flexible printing plates to transfer ink onto the film surface. It is suitable for repeat production runs and supports efficient printing of logos, text, graphics, and solid colors on flexible packaging films.
Rotogravure Printing
Rotogravure printing uses engraved cylinders to transfer ink onto the packaging film. It is commonly used for high-volume flexible packaging where consistent color reproduction and detailed graphics are important.
CMYK and Pantone Color Matching
CMYK printing uses cyan, magenta, yellow, and black inks to reproduce full-color artwork. Pantone or PMS color matching helps specify brand colors more consistently across packaging designs. Final color reproduction depends on the film, ink system, printing process, and production conditions.
White Ink Printing
White ink provides an opaque base for artwork and helps colors appear more clearly on transparent, metallized, or darker film structures. It can also be used for white text, logos, and design elements.
Metallic Printing Effects
Metallic effects can add reflective visual elements to logos, graphics, or accent areas. The final appearance depends on the selected ink, film structure, metallic substrate, and printing process.
UV-Cured Inks
UV-curable inks are cured using ultraviolet light after printing. They can provide fast curing and good surface resistance when used with compatible films, inks, and printing equipment.
Finishing options change the surface appearance and feel of your custom printed mylar bags. Choose a finish based on your artwork, film structure, and the look you want for your packaging.
Gloss Finish
Gloss creates a smooth, reflective surface that enhances color contrast and gives printed graphics a bright appearance. It works well for bold artwork and colorful packaging designs.
Matte Finish
Matte provides a smooth, non-reflective surface with a softer visual appearance. It reduces surface glare and gives packaging a clean, understated look.
Soft-Touch Matte
Soft-touch matte adds a smooth, velvety feel to the outer surface. It gives the pouch a distinct tactile finish while maintaining a low-glare appearance.
Spot UV
Spot UV applies a clear gloss coating to selected areas of the design. Logos, text, patterns, or other details can be highlighted against a matte background for added visual contrast.
Holographic Film
Holographic film creates a reflective effect that changes appearance as the viewing angle or lighting changes. It is suitable for designs that use reflective or multi-color visual effects.
Additional features make customized Mylar bags easier to open, handle, display, and use. We select each option based on your product, pouch structure, filling process, and retail requirements.
Tear Notch
A tear notch provides an easy starting point for opening the pouch. It allows customers to tear the bag open without using scissors.
Hang Hole
A hang hole allows the pouch to be displayed on peg hooks and other retail fixtures. It works well for products sold in hanging displays.
Rounded Corners
Rounded corners create a softer edge profile and reduce sharp corners around the pouch. They also give the packaging a cleaner finished appearance.
Clear Window
A clear window allows customers to see the product inside the pouch. The window structure should be selected carefully when barrier protection is important.
Degassing Valve
A degassing valve allows gases to escape from the package while helping limit outside air from entering. It is commonly used for products such as roasted coffee that release gases after packaging.
Resealable Zipper
A resealable zipper lets customers open and close the pouch multiple times. It is useful for products that are consumed or used in portions.

Sample Mylar Bags
Custom sample Mylar bags provide compact packaging for product samples, trial sizes, promotional products, and small quantities. Custom dimensions and printed artwork help maintain consistent packaging across sample and full-size product lines.
High-barrier personalized Mylar bags use multiple material layers that are bonded into a flexible film structure. Each layer serves a specific purpose, such as barrier protection, strength, printability, or heat sealing.
Adhesive Lamination
Adhesive lamination bonds two or more film layers into a single flexible structure. The adhesive and material combination are selected based on the required barrier, strength, sealing, and application needs.
Extrusion Lamination
In extrusion lamination, molten polymer is extruded through a die between compatible material layers. The polymer bonds the layers together while maintaining the flexibility and performance required for the final pouch structure.
Lamination Curing
Adhesive-laminated films may undergo controlled curing before pouch conversion. This allows the adhesive to develop the required bond strength. Curing conditions depend on the adhesive system and laminate structure.
Pouch Conversion
The laminated film rolls are converted into finished pouches using forming, cutting, and sealing equipment. Depending on the pouch style, the process may create gussets, folds, openings, and other structural features. The heat-sealable inner layer forms the package seals under controlled heat and pressure.
