3-Side Seal Agricultural Seed Bag

Product Details

Overview

The 3-Side Seal Agricultural Seed Bag - Heavy Duty uses a food-grade PET/PE multilayer film barrier with three sealed edges, ideal for sachets and flat packs of dry and semi-liquid food.

Key Features

Minimal material: Three seals use less film than gusseted formats, lowering pack cost.
Strong barrier: The food-grade PET/PE multilayer film laminate protects dry and semi-liquid food from oxygen and moisture.
Clean flat profile: Lays flat for stacking, mailing and single-serve dry and semi-liquid food.
Sachet or pouch: Scaled from small sachets to larger flat pouches.
Custom print: Gravure or digital printing with tear notch options.

Material & Barrier Protection

For dry and semi-liquid food, the food-grade PET/PE multilayer film web is specified for a reliable seal on all three sides.
