Retort pouches for pet food and wet food applications must deliver far more than conventional flexible packaging. Wet pet food, jellies, pastes, sauces and functional pet nutrition products are often thermally processed after filling – for example through autoclave sterilization or pasteurization. During these processes, heat, pressure and processing time place significant stress on the packaging material, seal integrity and overall pack performance.
As a manufacturer, we develop and produce retortable pouch and packaging solutions for pet food applications designed for real industrial production environments. Our Castelli® mono-material retort pouches combine proven shelf-life performance, high seal strength and reliable large-scale production capabilities with a recycling-oriented material concept.
Designed for pet food manufacturers looking to package wet food safely, future-proof their packaging structures and adapt their packaging solutions to upcoming PPWR requirements.
Retort pouches are a flexible packaging solution for wet pet food, moist pet nutrition products and functional pet food applications that undergo thermal processing after filling. Especially for wet dog and cat food, jellies, pastes or functional supplements, packaging must remain leak-tight, stable and visually appealing even after exposure to heat and pressure.
Our retort pouches are suitable for applications including:
Depending on the product, filling material, processing conditions and required shelf life, we tailor the material structure, barrier properties and pouch format to your specific application.
Many recyclable retort packaging solutions fail under real production conditions. In retort applications, a purely theoretical approach is not enough. Packaging must perform reliably throughout the entire process chain – during filling, sealing, autoclave sterilization, storage, transport and retail handling.
Our Castelli® mono-material retort pouches are specifically developed for these demanding requirements. They offer a recycling-oriented alternative to conventional aluminum-based or complex multilayer laminate structures and are already available for industrial-scale production.
Benefits of Mono-Material Retort Pouches:
This allows pet food manufacturers to better combine product protection, process reliability and sustainability requirements within one packaging solution.
Wet pet food and moist pet nutrition products place particularly high demands on packaging materials. Fat, salt, acidity, moisture and product particulates can affect packaging performance throughout the entire product lifecycle. In addition, sterilization and pasteurization processes place significant thermal and mechanical stress on both the material structure and seal integrity.
Typical Challenges for Retort Packaging in Pet Food Applications:
For this reason, our retort pouches are not designed purely for appearance or material reduction, but for reliable real-world performance under industrial production conditions.
Retort pouches offer pet food manufacturers a flexible, lightweight and space-saving packaging solution for wet pet food products. Compared to rigid packaging formats, pouches reduce storage and transportation volume, provide strong branding opportunities and enable modern portioning and convenience concepts.
Retort pouches are particularly attractive for dog and cat food applications where product protection, shelf life, user convenience and shelf appeal need to be combined in one packaging solution.
Available Formats Include:
On request, we develop the complete packaging solution including print design, material structure and compatibility with suitable packaging machinery.
With the introduction of the European Packaging and Packaging Waste Regulation (PPWR), requirements for recyclability, material efficiency and design-for-recycling are becoming increasingly important. Especially in wet pet food applications, this transition is challenging, as packaging must still provide high barrier performance, reliable seal integrity and full retort capability.
Mono-material retort pouches can offer a future-oriented solution in this area. They reduce material complexity and support more recycling-friendly packaging concepts without compromising product protection or process reliability.
The key factor is the precise technical design based on:
We support you in selecting and implementing the right retort packaging solution for your pet food product.
In addition to retort-ready pouches, we develop flexible packaging solutions for a wide variety of pet food products—from wet food and pastes to snacks, dietary supplements, and functional pet food. Depending on the application, we use various packaging formats such as stand-up pouches, flat pouches, tubular pouches, stick packs, sachets, and spout pouches.
Stick packs and sachets, for example, are suitable for liquid snacks, pastes, or supplements in small portion sizes, while stand-up pouches and spout pouches are frequently used for premium wet food or functional pet food products. We tailor the material structure, barrier properties, and sealing performance individually to the product, shelf life, and packaging process.

The terms “retort bag” and “retort pouch” refer to the same packaging solution. Both terms are used for flexible, heat-resistant packaging that can be sterilized or pasteurized after filling. Internationally, the term “retort pouch” is also frequently used.
Retort pouches are particularly suitable for wet food, pet food, sauces, pastes, and other products that undergo heat treatment in an autoclave. Modern single-material retort pouches offer a recycling-friendly alternative to traditional aluminum composite packaging. As a manufacturer, we develop retort-compatible packaging solutions for industrial applications in the pet food sector.
A retort pouch is a flexible packaging solution designed for heat-treated products. After filling, the product is sterilized or pasteurized inside the pouch. This makes the pouch particularly suitable for wet food, jellies, pastes, and shelf-stable pet food products.

Retort pouches are designed to withstand high temperatures and pressure during sterilization or pasteurization. Depending on their material composition, retort-safe pouches can withstand temperatures of up to 121 °C or 134 °C.
The decisive factors here are not only the temperature, but also:
For wet food, jellies, pastes, or functional pet food, we tailor the material composition and barrier properties individually to the respective production process.
Yes, retort pouches are specifically designed for use in autoclaves. They can withstand the heat, pressure, and moisture during thermal sterilization and are therefore ideal for wet food and other moist pet food products.
Autoclavable retort pouches must meet significantly higher requirements than traditional flexible packaging. Key requirements include:
Our retort pouches are designed for real-world production conditions and industrial mass production processes.
Yes, provided that the material structure, sealing medium, and process parameters are properly coordinated. Our Castelli® monomaterial retort pouches are designed for demanding retort processes and tailored for industrial applications.
Retort pouches for wet food must meet significantly higher requirements than traditional flexible packaging. During sterilization or pasteurization, high temperatures, pressure, and moisture directly affect the material, the seal, and the packaging structure. At the same time, product protection, shelf life, and packaging integrity must be maintained over the long term.
The following requirements play a particularly important role in dog and cat food:
Especially with wet food, unsuitable material structures can lead to delamination, seam failure, or loss of barrier properties. That is why modern retort pouches are individually tailored to the product, contents, retort process, and desired shelf life.
As a manufacturer, we develop retort-compatible packaging solutions for industrial pet food applications—from classic retort pouches to recycling-oriented monomaterial retort pouches.
Various pouch formats are available for retort applications—depending on the product, fill volume, and filling process. Flexible packaging solutions in many different variations are used, particularly in the pet food sector.
Possible retort pouch formats:
The selection of the appropriate format depends, among other factors, on the product, the retort process, the best-by date, and the packaging machine. As a manufacturer, we support you in developing a suitable retort-compatible packaging solution for your product.
Retort-compatible packaging, such as retort bags or retort pouches, is particularly well-suited for wet food. It allows for thermal sterilization in an autoclave and reliably protects the product from oxygen, moisture, and external influences.
Compared to cans or trays, flexible retort packaging offers several advantages:
lower packaging weight less shipping volume modern portion sizes large print and branding areas flexible pouch shapes Retort pouches are frequently used for dog and cat food, jellies, pastes, sauces, or liquid snacks. As a manufacturer, we develop customized packaging solutions tailored to the product, shelf-life requirements, and packaging machine.

Yes, in many cases it is possible to switch from aluminum composite packaging to single-material retort pouches. However, it is crucial that the new packaging be precisely tailored to the product, the retort process, and the desired shelf life.
Traditional aluminum composite packaging offers very high barrier properties but is often only partially recyclable. Monomaterial retort pouches can serve as a recycling-friendly alternative and help better address future PPWR and Design for Recycling requirements.
When making the switch, the following factors, among others, must be evaluated:
Not every existing aluminum structure can be replaced on a 1:1 basis. That is why we develop retort-compatible monomaterial solutions tailored to real-world production conditions and industrial mass production processes. The goal is to combine product protection, process reliability, and improved recyclability.
