Overview
Custom Glassine Bags from Mylar Bags NYC are made for food, supplement, cannabis, pet and retail brands that need packaging which protects freshness and sells on the shelf. We make every order to your size, print it in full color with your artwork, and choose a film structure that keeps your stamps, baked goods, coins and small items fresh from fill to final use.
Whether you're launching your first product or restocking a national line, we print custom glassine bags from 100 units, with free design support, a digital proof before production and turnaround of 10 to 15 business days after approval.
Packaging is part of the product. For stamps, baked goods, coins and small items, the bag controls freshness, aroma and shelf life, and it's often the first thing a customer touches. Well-made custom glassine bags reduce returns and waste, look great in photos and on shelves, and give you space for your story, usage tips and required information.

Design ideas
Ideas that work especially well for stamps, baked goods, coins and small items:
- Print one color on glassine.
- Use a flap closure.
- Keep it vintage.
- Add a sticker seal.
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 glassine bags are Small (2 x 3 in), Medium (3 x 5 in) and Large (4 x 6 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 glassine 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 glassine bags, we usually recommend grease-resistant glassine and flap closures, with a film thickness matched to the weight and shape of your stamps, baked goods, coins and small items. 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.
- Grease-resistant glassine: adds practical value during filling, display and use.
- Flap closures: closes cleanly without adhesive mess.
- One-color print: makes colors and details sharp.
Sustainable options
Want a lower-impact option? We can make custom glassine bags with recyclable mono-material PE structures, compostable films or kraft paper laminates, and reduce ink coverage. Each option trades some barrier performance, so we'll help you match it to your product's shelf-life needs.
