What materials are used in the manufacturing of Four-Side Seal Bags?

At Unified Flex, we manufacture four-side seal bags using both metalized and non-metalized materials. Our metalized films provide a strong barrier against oxygen and moisture, ideal for preserving freshness in products like snacks and beverages. Non-metalized films are suitable for products with shorter shelf lives or when a transparent look is preferred.

Our customization options include:

  • Flexographic printing with up to 12 colors for vibrant branding.
  • Glossy, matte, and UV finishes for enhanced shelf appeal.
  • High-barrier laminations for added protection.
  • Tear notches and resealable closures for convenience.
