Flat Bottom Pouches

Custom Flat Bottom Bags With Premium Shelf Presence

The flat bottom bag—sometimes called a box pouch—is the format brands reach for when they want their packaging to look as good as the product inside. With a wide, flat base and five distinct printable panels, it stands tall and square on the shelf like a rigid box, but with all the cost, weight, and storage advantages of a flexible pouch. At CustomMylarBags.Shop, every flat bottom bag is built to your exact specification, so the size, barrier, finish, and artwork all match your brand.

That boxy, structured footprint is why flat bottom bags have become the go-to for premium coffee, tea, granola, protein, pet food, and gourmet dry goods. The flat base means the bag holds more product in the same shelf width, and the front, back, two side gussets, and bottom give you more surface for branding, ingredients, and storytelling than almost any other pouch style.

Designed to Hold More and Show More

• Five printable panels — front, back, both sides, and bottom for maximum branding real estate
• Wide flat base — superior shelf stability and a structured, premium look
• Resealable zippers — keep contents fresh between uses
• Optional one-way degassing valve — ideal for freshly roasted coffee that needs to release CO₂
• Tear notches and tin ties — convenient, customer-friendly opening options

Standard Size Guide

Every flat bottom bag is made to order. The reference sizes below are popular across coffee and specialty foods; we’ll build any custom dimension and thickness you require.

Thickness guide: flat bottom bags typically run 4–6 mil to support their structured shape and barrier performance. We’ll match the gauge to your product and shelf-life needs.

FDA Food-Grade Barrier Protection

Every flat bottom bag is produced from FDA food-grade, BPA-free multi-layer film engineered to block oxygen, moisture, and light—the three things that stale coffee and degrade dry goods fastest. Add a one-way degassing valve for freshly roasted beans, or specify a higher barrier for long shelf-life products. Full certifications are available on request to meet your category’s requirements.
