Custom Printed Three Side Seal Pouches | Aluminum Foil Flat Bags for Food & Snack Packaging - Linyi Gerun

Product Overview

Our three side seal pouches (3-side seal flat bags) are the versatile workhorse of flexible packaging, offering a clean, classic look with reliable barrier protection. These flat pouches are manufactured with precision heat sealing on three sides, leaving one side open for product filling and final sealing. Perfect for portion-controlled snacks, single-serve products, and lightweight dry goods, our three side seal pouches combine cost-effectiveness with excellent brand presentation through vibrant rotogravure printing.

Material & Structure

Our three side seal pouches utilize a multi-layer lamination structure: PET (outer layer for printability and durability) / Aluminum Foil (middle barrier layer) / PE (inner sealant layer for heat sealing and food safety). This proven structure provides OTR below 0.5 cc/m²/day and WVTR below 0.5 g/m²/day. For products requiring visibility, we offer transparent PET/PE structures with optional foil lamination for barrier enhancement.
