Aluminum foil spouted stand-up pouch

Product Overview

The aluminum foil stand-up pouch with spout is a new type of flexible packaging container that integrates self-standing support and convenient drinking. The product consists of a stand-up pouch and a spout tightly combined. The bottom features a stand-up bottom design, allowing the pouch to stand firmly without external support. A food-grade spout is provided at the top or on the side, which can be opened and resealed multiple times, making it easy for consumers to drink directly from it or pour out the contents.

Laminate Structure

The product uses a multi-layer laminated film structure. Common material combinations are as follows:

• Outer layer: PET (polyester) for printing substrate and scratch resistance.
• Middle layer: Aluminum foil (AL) as the core barrier layer, providing excellent oxygen, light, and moisture barrier performance.
• Inner layer: PE (polyethylene) or RCPP (retortable polypropylene) for heat-sealing and food-contact safety; RCPP is used for high-temperature retort applications.
• Optional structures include: PET/AL/PE (standard), PET/AL/PA/PE (enhanced puncture resistance), and PET/AL/NY/RCPP (retortable, up to 121°C).

Key Features

• Self-standing: The bottom design allows the pouch to stand upright, facilitating display, storage, and filling operations.
• Convenient drinking: The spout supports one-hand operation, ready to drink, prevents spills, and can be resealed and refrigerated if not finished.
• High barrier: The aluminum layer provides extremely low oxygen and water vapor transmission rates, effectively extending product shelf life.
• Lightweight and portable: Light in weight, and the pouch shrinks as content decreases, making it easy to carry.
• Heat resistant: Some grades can withstand retort sterilization at 121°C, suitable for hot-fill and post-sterilization processes.
• High-quality printing: Supports multi-color gravure printing, with a large printable area for brand presentation.
