Not sure where to start? Tell us what you're packing, the fill weight and where it's sold, and we'll recommend a size, film and finish in your free quote. Our most requested sizes for custom window mylar bags are Small (4 x 6 x 2 in), Medium (5 x 8 x 3 in) and Large (7 x 11.5 x 4 in). Smaller sizes suit samples and trial packs, the middle size usually fits your core product, and larger sizes work for family packs, bulk and wholesale. Because density varies, we always recommend testing your actual fill before printing. Fill custom window mylar bags through the top before sealing, leaving at least 1 inch above the zipper. For the strongest closure, use an impulse or band heat sealer set to the temperature recommended for your film. If you're using oxygen absorbers or desiccants, add them just before sealing, and store finished bags away from direct sunlight and heat.
Protection and performance
Flexible packaging has to protect against oxygen, moisture, light and punctures. For custom window mylar bags, we usually recommend custom windows and zippers, with a film thickness matched to the weight and shape of your snacks and treats. Sharp or heavy products may need a thicker gauge; aromatic products need a high-barrier, smell-resistant structure. Tell us what you're packing and we'll suggest the right build.
- Custom windows: lets shoppers see the product, building trust.
- Zippers: lets customers reopen and reseal the bag, keeping contents fresh.
- Barrier films: blocks oxygen, moisture and light to extend shelf life.

Sustainability is increasingly important to shoppers. Recyclable, compostable and kraft-look structures are available, and we can print a clear end-of-life message on every bag.
