This page explains tear-strip Mylar packaging—pouches with a removable strip sealed above the zipper. Removing the strip provides clear tamper evidence while maintaining a reclosable zip for continued use. We cover compatible film stacks like PET/VMPET/PE, sealing zones, and sizing for U.S. retail categories.

Since 2018, Seven Packaging has delivered 500+ Mylar projects across the U.S., producing custom-printed tear-strip bags that balance shelf appeal, freshness, and compliance. Where applicable, tamper-evident features align with 21 CFR 211.132 guidance for tamper-evidence.

Why Choose Tear-Strip Mylar?

  • Clear first-open proof: The removable strip shows visible access before sale—ideal for retail trust.
  • Resealable after opening: Customers remove the strip, then use the built-in zipper for ongoing freshness.
  • Barrier & shelf-life: Laminates like PET/VMPET/PE protect aroma and humidity-sensitive products.
  • Brand-ready look: Matte or gloss, windowed fronts, hang holes, rounded corners, and premium finishing.
