Custom Gusset Mylar Bags for Better Fill Capacity and Product Protection
A gusset adds extra material to the side or bottom of a bag so it can expand when you fill it. This prevents the bag from bulging against a flat seal, reduces stress on the seams, and gives you more usable fill volume without requiring the same increase in the front footprint. We supply both side gusset and bottom gusset Mylar bags in printed and stock options, with or without a zipper.
Take your brand to new heights of success by making the right, cost-effective strategy with Gusset Mylar bags. How do these bags save you? When you pack your products in these Mylar bags, your products can stay intact for years, which results in reduced recurring product manufacturing costs.
Likewise, their lightweight nature and expandable structure reduce shipping costs while keeping your products safe from oxygen and moisture. Customize custom Mylar bags with vibrant colors and unique designs to turn heads.
Oxygen-Resistant Materials and Construction for Gusset Mylar Bags
High-quality and flexible materials are used for creating all kinds of Mylar pouches. You may consider choosing from the following popular types of Mylar bags for your products:
Custom Gusset Mylar Bags
Mylar packaging is normally a laminate rather than a single film. A typical structure can use PET or BoPET as the outer layer for strength and printability, metallised PET or aluminium foil as the barrier layer, and polyethylene or LLDPE as the inner heat-seal layer. Adhesive lamination bonds these layers into one flexible structure.
Mil thickness affects stiffness, puncture resistance, and barrier construction. A 3.5 mil structure suits lighter products and flexible retail packs, 5 mil is a practical choice for many food, powder, and dry-goods applications, and 7 mil suits heavier products or applications where additional durability is needed. Actual thickness and laminate structure should be selected according to the product, fill weight, and seal requirements.
OTR, or oxygen transmission rate, tells you how much oxygen can pass through the packaging material over a specified period. MVTR, or moisture vapour transmission rate, tells you how much water vapour can pass through it. Lower OTR and MVTR values generally indicate stronger oxygen and moisture barrier performance.
Aluminium foil is opaque and blocks light completely. Metallised PET provides a lighter-weight reflective barrier, while a transparent laminate can be selected when product visibility is required.
Custom Kraft Mylar Gusset Bags
Another excellent type of gusset bag is custom kraft mylar bags that are known for their sustainability and brown charm. A layer of PET is adhered to the kraft paper to create expandable gusset mylar pouches for food and cosmetics.
A kraft paper laminate can combine the printable surface of kraft paper with PET, metallised PET, foil, and polyethylene layers to create a functional laminate structure.
For direct food contact, the complete packaging structure should be specified for its intended use. FDA food contact status applies to the relevant substances and conditions of use, not simply to the word “Mylar.”
Printed Gusset Mylar Bags for Product Identification
At The Customize Boxes, you are offered the option to choose from printing to the final touches for your product packaging to add a personalized touch. For custom printed gusseted bags, you can select flexographic printing, rotogravure printing, or digital printing according to your quantity, artwork, and color requirements.
Vibrant Colors and Designs
Custom-printed Mylar bags help you showcase your brand identity compellingly in the marketplace. For this, you will have to choose from the color scheme, fonts, imagery, and design themes to print Mylar gusset bags that align with your brand persona.
Flexographic printing works well on flexible film because the process uses flexible printing plates and fast-running presses. Rotogravure printing uses engraved cylinders and is suited to repeat, high-volume film production where consistent color reproduction is required. Digital printing is useful for shorter runs, variable artwork, and designs without traditional plates or cylinders.
High-grade inks and vibrant colors are used to print gusset mylar bags. Effective printing technology is used to print with high-resolution graphics.
Sleek and Protective Coatings
Get your gusseted Mylar bags coated with some sleek and tactile varnishes for a lasting impression. Some popular finishes include debossing, matte, gloss, embossing, spot UV, soft touch, and hot stamping. Finish selection should match the film surface, printing process, handling conditions, and required appearance.
These finishes help you enhance your customers’ tactile experience while highlighting the printed design on your custom mylar bags.
Unique Styles and Shapes
Get every shape and style customized for gusseted mylar bags to exude uniqueness. Share your ideas and get them incorporated into the gusseted mylar bags. However, some popular styles include Mylar bags with a window, vacuum-sealed Mylar bags, custom-shaped Mylar bags with gussets, Mylar bags with Ziploc, resealable Mylar bags, and child-resistant Mylar bags.
For artwork, we supply the dieline. Provide artwork at 300 dpi in CMYK, with named Pantone colors where required, and include a 3 mm bleed.
Custom Gusset Mylar Bag Sizes and Capacity
Gusset depth is separate from width and height. It controls how far the side or bottom expands and can increase fill volume without greatly increasing the front footprint. Capacity varies by product density, so confirm the size with your actual product. A 1 gallon bag holds about 1 gallon by volume, while 1 lb, 5 lb, and 1/4 oz capacities vary by product type.
Consider fill weight, product density, gusset depth, seal width, seal strength, headspace, closure, and shipping requirements when selecting your bag.
Gusset Mylar Bags for Specific Product Uses
Gusset structures are useful when your product needs additional fill volume, barrier protection, or a stable package format. Common applications include:
- Coffee beans and loose-leaf tea
- Spices and nuts
- Dried fruit and grains
- Flour and powders
- Protein powder
- Pet treats
- Soil and garden amendments
- Hardware and small parts
For products that require odor containment, you can specify smell-proof mylar bags with an appropriate barrier structure and closure. For products requiring permanent closure, heat-seal mylar bags can be considered. For products that need repeated opening, resealable mylar bags with a zipper can be used.
