How to Fill and Seal Spout Pouches? Answers For You

Why have spout pouches become the darling of the packaging industry? In the fast-paced modern life, convenient, practical, and high-value packaging has become the key for brands to win consumers. Custom spout pouches have quickly occupied multiple fields such as food, daily chemicals, and pet products with their ease of use, sealing, and customizable design.

As a spout pouch manufacturer with 30+ years of deep cultivation in the industry, we are well aware of every link from production to use. Today, PAQUETE DQ will share how to correctly fill and seal spout pouches, and analyze the core value of choosing a professional supplier for you.

Step 1: Filling Tips for Spout Pouches

Filling spout pouches may seem simple, but improper operation may cause leakage or waste. Whether it is liquid, powder, or paste, the following steps can ensure that the process is efficient and safe:

Choose the Appropriate Spout Specifications

Choose a spout with a suitable diameter according to the viscosity of the contents, such as a larger opening for high-viscosity sauces.

Positioning and Fixing

Place the spout pouch vertically on the filling equipment to avoid tilting and causing overflow.

Control the Filling Amount

Reserve the top space (5%-8% is recommended) to prevent the contents from leaking under pressure when sealing.

As a professional manufacturer of custom printed spout pouches, we provide one-stop support from capacity design to filling suggestions to ensure that your products are both beautiful and practical.

Step 2: Seal Spout Pouches Process

The sealing strength of the spout pouch directly affects the shelf life and user experience. Common sealing methods include:

Heat Sealing Technology

through high-temperature pressing of the inner layer material, suitable for most contents.

Ultrasonic Sealing

no heat source contact, suitable for temperature-sensitive products.

Zipper Sealing

Repeatable opening and closing design to improve convenience.
