Retort Pouch Manufacturer
The 139th Spring Canton Fair 2026 will grandly open in Guangzhou from April 15 to May 5.
During the fair, numerous buyers will select suitable automatic packaging equipment, while also striving to find custom packaging bag suppliers. High-quality packaging bags serve as a crucial support for product competitiveness.
The retort pouch stands as our most distinctive custom packaging product and a popular category at this year’s Canton Fair. With the rapid development of the food, pharmaceutical and other industries, the market demand for retort pouches keeps rising, and their importance has become increasingly prominent, making them an indispensable packaging choice for many enterprises.
I. Importance of Retort Pouches
- Reduced packaging costs
Traditional packaging (such as tin cans and glass bottles) features large volume, heavy weight, high unit price, elevated transportation and storage costs, and is prone to damage.Retort pouches have small transportation volume, light weight, low transportation costs and low customization costs.
- Extended product shelf life
Ordinary plastic packaging, glass bottles and tin cans cannot withstand high-temperature sterilization, making it difficult to ensure product shelf life and safety.Retort pouches combine the advantages of high-temperature sterilization resistance with the portability and flexibility of flexible packaging.They can undergo sterilization in a high-pressure environment at 121°C to 135°C or even higher temperatures, effectively killing all bacteria and extending product shelf life. Meanwhile, they firmly lock in the original flavor and nutrition of contents, are lightweight and portable, and boast excellent printing, helping enhance product appearance and brand recognition.
II. Applications of Retort Pouches
- Food industry
This is the core application scenario of retort pouches, suitable for prepared meals, meat products (cooked meat, sausages), aquatic products (ready-to-eat seafood), instant food, pet snacks, baby food supplements, etc.
- Pharmaceutical field
Used for packaging medical nutrient solutions, traditional Chinese medicine extracts, sterile preparations and other products. They can withstand various sterilization methods and meet the stringent requirements of the pharmaceutical industry for biocompatibility and chemical properties of packaging materials.
III. Features of Retort Pouches
- High temperature resistance
Capable of withstanding autoclaving at 121°C–135°C without rupture, shrinkage, delamination, odor or harmful substance precipitation, fully complying with FDA and other food contact packaging safety standards.
- Excellent high barrier properties
Multi-layer composite structures such as PET+NY+RCPP or PET+NY+ALUMINUM FOIL+RCPP effectively block the penetration of oxygen, water vapor and peculiar smells, preventing product oxidation, moisture absorption and flavor cross-contamination, and greatly extending the ambient temperature shelf life of products.
- High toughness and safety
Possess outstanding puncture resistance and impact resistance, capable of withstanding sharp edges of bones and hard food materials to avoid bag breakage and leakage during transportation and sterilization. Made of food-grade eco-friendly materials with no risk of toxic substance migration.
IV. How to Choose the Right Retort Pouch for Your Product
- Select the appropriate temperature based on product characteristics
121°C is suitable for ordinary ready-to-eat food, sauces, etc.
135°C is designed for high-end demands such as baby food, perishable food and military rations that require longer shelf life or better sterilization effects.
- Barrier performance requirements of the product
For ready-to-eat food with a shelf life of 1 year or more, aluminum foil structures (PET/NY/ALU/RCPP) are preferred.For products requiring visibility and microwave heating, transparent structures (PET/NY/RCPP) are recommended.
- Pouch style selection
- Three side seal pouch: Suitable for small-capacity products of 50g–200g, such as sauces, pet food, sliced ready-to-eat sausages, etc.
