Why Should We Choose the Flat Poly Bag?
Layflat poly bags keep your packaging costs in check without cutting corners on quality. They’re a smart, budget-friendly choice that still delivers solid performance.
From food and hardware to personal goods, these bags do it all. Whatever you’re packing, there’s a flat poly bag that fits the job perfectly.
These bags lay flat and pack efficiently, saving space in storage and during transport. They’re ideal for high-volume production and fulfillment lines.
Customize Your Flat Poly Bag
Show off what’s inside. A clear window gives customers a quick look at your product, helping build trust and making it easier to choose your brand on the shelf.
Make opening simple and frustration-free. Tear notches let customers open the bag cleanly without scissors, giving them a better experience from the first use.
Control the final look. Matte gives a premium feel, gloss adds shine, and spot gloss highlights key elements for an elevated, branded finish.
Some products need to breathe, others just need to let air out. We add vent holes where they make sense, so your product stays fresh and functional.
Want your bags to hang in-store? No problem. We can add hang holes so your product gets seen wherever it’s stocked: on hooks, pegs, or point-of-sale displays.
Choose the closure that fits how your product is used. Whether it's a heat seal, resealable zipper, adhesive strip, or twist tie, we ensure your packaging works the way it should.
