Product Details

Overview

3-Side Seal Snack Packaging Bag - Custom Printed is a 3-side seal bag, the simplest laminated format for snack where cost and clean sealing matter.

Key Features

  • Clean flat profile: Lays flat for stacking, mailing and single-serve snack.
  • Strong barrier: The food-grade PET/PE multilayer film laminate protects snack from oxygen and moisture.
  • Custom print: Gravure or digital printing with tear notch options.

  • Sachet or pouch: Scaled from small sachets to larger flat pouches.
