Custom Retort Pouches for Shelf-Stable Food

A retort pouch is a multi-layer laminated pouch that is filled, sealed and then sterilized in a retort at 116–135 °C (240–275 °F), so ready meals, rice, soups, wet pet food and sauces keep at room temperature without a can. YLTPACK builds the laminate for your exact retort cycle, prints it and makes the pouches in our cleanroom plant in Shenzhen.

THE BASICS

What Is a Retort Pouch?

A retort pouch is a flexible can. The product is sealed inside a heat-resistant laminate, then the filled pouch is sterilized under pressure in a retort, usually at 116–121 °C and up to 135 °C for short high-temperature cycles. After sterilization the food is commercially sterile and needs no refrigeration until it is opened.

Two parts of the pouch do the hard work: an outer barrier that keeps oxygen and light out for the whole shelf life, and an inner RCPP sealant that holds its seal at sterilization temperature and is the only layer that touches the food.

In the US, low-acid foods in pouches are processed under a scheduled process filed with the FDA (21 CFR 113). Your process authority sets the cycle; we build the pouch to survive it.

We put the recycling row in on purpose: if a curbside-recycling claim matters more than weight and shelf impact, a can may still be the better pack.

START WITH YOUR PROCESS

Match the Pouch to Your Retort Cycle

The laminate is chosen by the heat it has to survive, not by how the bag looks. Find your process below, then send us the six numbers below and we recommend one structure in writing.

Up to 100 °C

212 °F and below

Hot fill & pasteurized

Typical productsHot-filled sauces and soups, boil-in-bag sides, pasteurized drinks and purees.

What we buildNY/PE or PET/NY/PE. Cheaper than a retort laminate and fine at this heat.

See the structures ↓

116–121 °C

240–250 °F

Standard retort

Typical productsReady meals, curries, cooked rice, beans, soups, wet pet food and most sauces.

What we buildPET/AL/RCPP for long shelf life, or clear PET/NY/RCPP when it must go in the microwave.

See the structures ↓

121–135 °C

250–275 °F

High-temperature retort

Typical productsMeat on the bone, seafood, dense low-acid fills, field rations and short high-heat cycles.

What we buildPET/NY/AL/RCPP. The nylon layer resists bones and flex cracking under pressure.

See the structures ↓
Send us these six and we can specify your pouch:
  1. Peak temperature and hold time
  2. Static or rotary retort, and counter-pressure
  3. Fill: liquid, chunks, or meat on the bone
  4. Fill weight and pouch format
  5. Shelf life you need at room temperature
  6. Microwave reheating: yes or no

Retort Pouch Structures We Make

Four laminates cover almost every retort product we are asked for. Thicknesses are our typical builds in microns; we adjust the sealant gauge to your fill weight.

Ratings are typical for planning. The final rating depends on adhesive and sealant grade, so we confirm it on a test run of your own cycle before printing.

FORMATS

Pick a Format, Then a Size

All four formats are made in the structures above. Options: tear notch, round corners, retort-grade zipper, spout, matte or gloss finish, and a clear window on foil-free builds.

Stand-up retort pouch

Bottom gusset so it stands on shelf. Most chosen for ready meals, rice and wet pet food. Tear notch standard.

Retort spout pouch

Retort-grade spout and cap for baby food purees, sauces and drinks squeezed straight from the pouch.

Flat three-side seal pouch

Lowest cost per pouch and fastest heat penetration. Single-serve meals, tuna, field rations.

Shaped retort pouch

Die-cut outline for shelf presence on kids’ meals, sauces and premium ranges.

WHAT CAN GO WRONG

Six Ways Retort Pouches Fail, and How We Build Against Them

A retort pouch only fails in one place that matters: in your vessel, full of your product. These are the failures processors tell us they have seen with other pouches, and what we do about each one.

Leak testing in our own lab: the same test runs on retort seals
FailureWhat you seeHow we prevent it
DelaminationLayers separate or blister after the cycleRetort-grade laminating adhesive and full curing before bag making; bond and seal strength checked on our tensile tester
Seal creep or burstSeals open in the vessel or pouches balloon during heat-upRCPP sealant with wider retort seals, seal and leak tests, and advice on counter-pressure for your cycle
Pinholes and puncturesBones, grains or flexing crack the foil, leading to leaks and spoilageA nylon layer and heavier sealant for bony or particulate fills
Wrinkles and curlPouches distort in the retort and look damaged on shelfA balanced structure with sealant grade matched to your peak temperature, proven on a test run
Off-odorResidual solvent from ink or adhesive taints the foodFully cured laminate; odor is one of our 11 release checks on every order

FROM RETORT CUSTOMERS

What Food Processors Tell Us

Three customers who run our pouches through their own retorts, in the US, Canada and the UK.

Switching to YLTPACK’s retort pouches was one of the smartest decisions we’ve made. The seal strength and consistency are far better than what we used before, and the team actually understands the technical requirements for 121°C sterilization. They catch issues before production, which saves us time and headaches. Highly recommend.
Emily CarterEmily CarterProcurement Manager, RTE Meal Manufacturer, USA
Their QC reports and traceability give us real confidence. Every batch is documented, the color stays consistent, and the pouches hold up perfectly during our 30-minute retort cycles. Communication is fast and professional — feels like working with an in-house team rather than an overseas supplier.
Elly BrettElly BrettSauces & Soups Processor, Canada
We run many SKUs in different sizes, and YLTPACK handles them all without delays. The pouch strength is excellent, even for heavier wet-food loads. What we appreciate most is the transparency — no hidden fees, quick sampling, and honest delivery timelines we can actually plan around.
Sarah NguyenSarah NguyenOperations Manager, Premium Pet Food Brand, UK

Retort Pouch Questions, Answered

Straight answers on temperatures, structures, microwaving, shelf life and ordering.

Our standard retort structures are built for 116–121 °C (240–250 °F). The four-layer PET/NY/AL/RCPP build is used for high-temperature cycles up to 135 °C (275 °F). The final rating depends on adhesive and sealant grade, so we confirm it with a test run of your own cycle.

Choose by process and shelf life. PET/AL/RCPP covers most ready meals and rice at 121 °C. Add nylon (PET/NY/AL/RCPP) for bone-in meat, seafood and cycles above 121 °C. Choose a clear PET/NY/RCPP build when the pouch must be microwaved or show the food, and accept a shorter shelf life.

Only foil-free, clear builds such as PET/NY/RCPP or NY/RCPP. We do not recommend microwaving a pouch that contains aluminum foil. If microwave reheating is a must, tell us at the start so we specify a clear structure.

It depends on the structure, the product and your process. Foil structures are the usual choice for long ambient shelf life; clear structures suit shorter shelf life. Your process authority validates the final figure for your product; we supply the barrier that supports it.

Yes. SGS tested our PET/NY/AL/RCPP retort laminate against EU 1935/2004, (EU) No 10/2011 and (EU) 2025/351 and it passed (report CANEC25016938501). Pouches are made in a cleanroom under ISO 22000 food safety management, and we send the documents that match your structure with the quote.

A window is only possible on a clear, foil-free build, because a foil pouch cannot be see-through. We do not recommend a window when you need the longest shelf life. Most retort pouches open with a tear notch; if you need a zipper we use a retort-grade one and prove it on a test run.

10,000 pieces per design. Retort pouches are printed by rotogravure only, up to 10 colors, with the print reverse printed between layers; we do not digitally print retort pouches. Lead time is 7–15 days after artwork approval.

Yes, and we recommend it. We send free stock samples of the closest structure so you can run them through your own retort; you only cover the courier. Custom-structure test pouches can be made before full production.

Not in most curbside programs. Multi-layer pouches with foil are hard to separate. They do use far less material and transport than cans and jars, but if a curbside-recycling claim is essential, tell us and we will talk you through the trade-offs honestly.
