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 mylar envelope are 4 x 6 (4 x 6 in), 6 x 9 (6 x 9 in) and 9 x 12 (9 x 12 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 mylar envelope 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 mylar envelope, we usually recommend peel-and-seal flaps and metallic films, with a film thickness matched to the weight and shape of your documents, cards and flat 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.
- Peel-and-seal flaps: creates an airtight closure.
- Metallic films: protects the product and sets the look.
- Flat formats: adds practical value during filling, display and use.
