Why Choose Our Retort Pouches
Custom Retort Pouches | Shelf-Stable Food Packaging for RTEs and Thermal Processing
Retort pouches are flexible packaging that withstands the high-temperature, high-pressure sterilization process used to produce shelf-stable food products — replacing the traditional metal can with a flexible format that offers superior consumer convenience, better nutritional retention, faster processing times, and dramatically superior brand presentation through full-surface printing. Our retort pouches are manufactured from validated multilayer film constructions meeting the demanding thermal, mechanical, and barrier requirements of commercial retort sterilization.
The Retort Process
Retort sterilization heats food products to 240–250°F/116–121°C under pressure in autoclave retort systems — temperatures sufficient to achieve commercial sterility (12-log reduction of Clostridium botulinum) for shelf-stable food production. Retort pouches must maintain seal integrity, film integrity, and barrier performance throughout this process and during the subsequent shelf life of the product (typically 18–36 months at ambient temperature).
Retort Pouch Advantages vs. Cans
- Faster heat penetration: Thin pouch profile heats more uniformly than cylindrical can — shorter process times, better nutrient and flavor retention
- Consumer convenience: Tear-open flexible pouch vs. can opener — preferred by consumers across demographic groups
- Superior printability: Full-surface CMYK rotogravure printing vs. label-only can communication
- Reduced weight: 70–80% lighter than equivalent metal can — lower shipping costs
- Shelf space efficiency: Flat-packed retort pouches require less retail shelf space than equivalent can displays
Retort Pouches vs. Metal Cans: The Conversion Case
The food industry has been converting from metal cans to retort pouches for 40 years, and the pace is accelerating as consumer preference for convenient, sustainable packaging grows. The retort pouch's thin profile means heat penetrates from both sides simultaneously — the center of a pouch reaches sterilization temperature in minutes while the center of an equivalent can takes much longer. This faster heat penetration means shorter process times, which translates directly into better nutrient retention, superior flavor quality, and lower processing energy costs — a compelling case for food manufacturers optimizing for both product quality and operational efficiency.
Retort Pouch Validation Requirements
Retort pouch production for commercial food use requires process validation that demonstrates the pouch material, seal construction, and filling/sealing process consistently achieve commercial sterility. FDA 21 CFR Part 113 governs the thermal processing of low-acid canned foods — which includes retort pouches — and requires that all retort processes be filed with FDA and conducted by a certified process authority. Our retort pouches are produced from validated film constructions with documented material testing and are compatible with the standard retort process validation protocols used by major food manufacturers and aseptic co-packers.

Retort Pouches in Wisconsin — FAQs
What temperatures do retort pouches withstand?
Our retort pouches are validated for sterilization at 250°F/121°C under retort pressure for the time periods required to achieve commercial sterility in standard retort processing cycles. The film construction maintains seal integrity, barrier performance, and physical integrity throughout the retort process and the subsequent ambient shelf life.
What are retort pouches made from?
Standard retort pouch constructions use PET/foil/PP (polyester/aluminum foil/polypropylene) or PET/foil/CPP (cast polypropylene) — the polypropylene inner layer provides the high-temperature heat seal capability required for retort processing. EVOH-containing constructions add enhanced oxygen barrier for sensitive food applications.
How long is the shelf life of retort-packaged food?
Properly processed and packaged retort pouch products achieve commercial sterility with ambient shelf life of 18–36 months depending on the product, the process parameters, and the packaging barrier. Shelf life validation through challenge studies and accelerated aging testing is required to substantiate specific shelf life claims.
Can retort pouches be stand-up format?
Yes. Retort stand-up pouches use the same bottom gusset construction as standard stand-up pouches but are manufactured from high-temperature-rated film constructions. Stand-up retort pouches are popular for pet food, RTE vegetables, and specialty food retail applications where shelf presence and consumer convenience are priorities.
Do you make specialty packaging for Wisconsin's cheese and dairy brands?
Yes. Wisconsin's artisan cheesemakers, dairy brands, and specialty food producers use our custom retail boxes and gift sets to sell Wisconsin-made dairy products through specialty grocery, cheese shops, and direct-to-consumer channels nationally.
