What is retort pouch?
A retort pouch is a flexible packaging solution that consists of multiple layers of barrier materials, such as plastic and aluminum foil, combined to create a pouch capable of withstanding high-temperature processing ( normally 121℃ and 135℃). The pouches are sealed to maintain product freshness and integrity.
Customizing a retort pouch can present several challenges due to the specific requirements of this type of packaging. As BOWE PACK is a professional retor pouch manufacturer with years of industry experience, we can customize and manufacture the durable and safety retort packaging for you and your clients.
1. Heat Resistance:
Retort pouches are designed to withstand high-temperature processing, which involves sterilization and high temperature cooking. Choosing materials that can withstand these extreme conditions, our packaging engineers will give you the most suitable material structure suggestions based on your product characteristics and cooking temperature.
2. Barrier Properties:
Retort pouches need to provide an effective barrier against moisture, oxygen, and light to ensure the preservation and extended shelf life of the packaged retort food.Through mature technology and experience, we can achieve the right balance of barrier properties while maintaining other functional aspects of the pouch.
3.Material Compatibility:
The compatibility between the retort pouch materials and the specific food product being packaged is crucial. Different food products have varying sensitivities to certain materials, and finding a material combination that is safe, doesn't affect the taste or quality of the food, and meets regulatory requirements can be a challenge.
4. Product Safety and Integrity:
Ensuring that the retort pouch maintains the safety and integrity of the food throughout the processing and storage is of utmost importance. Any compromise in the seal strength, material stability, or barrier properties can lead to contamination, spoilage, or compromised product quality.

The microwavable retort pouch is designed to be used safely in a microwave oven without the risk of electric sparks. Unlike traditional retort pouches that utilize an aluminum layer, the microwavable version features a polyester film coated with Alumina (AlOx). This Alumina-coated polyester film provides a barrier property that is comparable to that of an aluminum layer.
By using Alumina-coated polyester film, the microwavable retort pouch maintains similar barrier properties in terms of oxygen transmission rate (OTR) and water vapor transmission rate (WVTR) as the ordinary retort pouch with an aluminum layer. This means that the microwavable retort pouch effectively protects the food inside from oxygen and moisture, ensuring the preservation of flavor, freshness, and quality.
Material structure: AlOx coated PET/NY/ RCPP
Usage: Cooked rice, curry sauce, soup, meat stew, pet meal & other ready-to-eat foods
