In today’s competitive packaging world, spout bags have become one of the most popular and versatile packaging solutions for liquid and semi-liquid products. They combine flexibility, durability, and convenience, offering an eco-friendly alternative to traditional bottles and rigid containers.
At Asia Packaging Group, we specialize in manufacturing high-quality spout pouches for beverages, sauces, detergents, cosmetics, and many other industries. This guide will walk you through everything you need to know about spout bags — from their structure and types to applications and benefits.
What Are Spout Bags?
A spout bag (also known as a spout pouch) is a type of stand-up flexible packaging equipped with a spout and cap for controlled pouring or drinking. These bags are made from multi-layer laminated films that protect the product from oxygen, moisture, and light — ensuring long-lasting freshness and safety.
Unlike rigid bottles, spout bags are lightweight, space-saving, and cost-efficient, making them an ideal choice for modern liquid packaging needs.
Structure of a Spout Bag
A typical spout pouch is made up of three main parts:
- Body Material (Laminated Film):
- Common structures: PET/NY/PE, PET/AL/PE, or recyclable mono-PE.
- Provides barrier protection, strength, and flexibility.
- Spout & Cap:
- The spout serves as the opening for pouring, drinking, or filling.
- Caps can be screw-on, flip-top, or child-resistant, depending on the product.
- Bottom Gusset (Doypack Base):
- Allows the pouch to stand upright, improving shelf display and stability.
🧴 Types of Spout Bags
Spout bags can be customized in shape, size, and structure to suit different industries. Below are the most common types:
- Standard Stand-Up Spout Pouch
Ideal for beverages, sauces, and detergents — available in various sizes. - Flat or Shaped Spout Pouch
Custom die-cut into creative shapes (fruit, bottle, cartoon characters) for branding appeal. - Retortable Spout Pouch
Designed to withstand high-temperature sterilization (up to 125°C) for hot-fill or pasteurized products like soups and sauces. - Side Gusset Spout Pouch
Offers extra volume and stability for larger capacities, such as 1L to 5L liquid packaging. - Bottle-Shaped Spout Pouch
Mimics the look of a bottle while retaining the lightness and flexibility of a pouch. - 2-in-1 Dual Spout Pouch
