Overview
What Is a 3-Side Seal Sachet?
A 3-side seal sachet is a flat, compact pouch sealed on three edges to provide high leak resistance and controlled single-use dispensing. It is ideal for samples, trial packs, and small-dose formats.
Technical Structures and Material Options
- PET/PE: Cost-efficient structure for standard sachet programs
- PET/AL/PE: High barrier for oxygen/light-sensitive products
- PET/METPET/PE: Strong aroma protection with balanced cost
- PA/PE: Improved puncture resistance for demanding or vacuum applications
Why Brands Prefer 3-Side Seal
This format delivers high sealing reliability with low material consumption in small-fill packs. The symmetric sealing geometry supports cleaner output, lower leakage risk, and efficient case packing.
Common Applications
Single-serve spices and sauces: Hygienic dosing and portion control.
Cosmetic sampling: Premium presentation at low unit cost.
Medical and personal care: Safe transport and controlled usage.
Powder and liquid additives: Secure filling with the right laminate.
Customizable Features
Tear notch, euro slot, matte/gloss finishes, and barrier tuning can be selected based on retail channel and product sensitivity, so function and shelf appeal are optimized together.
