When it comes to high-temperature retort packaging, experience matters.
At Wellfa Print & Pack, we have been researching and producing retort pouches since 1992, making us one of the earliest and most experienced retort pouch manufacturers in China.
Rooted in China’s Retort Food Market
In China, retort packaging has been widely used for decades. Many popular foods — such as spicy snacks, chicken feet, bamboo shoots, cooked meat products, and other ready-to-eat foods — require high-temperature sterilization to ensure safety and long shelf life.
From the very beginning, Wellfa has worked closely with leading domestic food brands, supplying reliable, safe, and high-performance retort packaging. This long-term cooperation helped us build a strong technical foundation and deep understanding of different food applications.
Retort Packaging Goes Global
Today, retort pouches are becoming increasingly popular worldwide, especially as a modern alternative to metal cans.
They are widely used for:
- Sauces and condiments
- Luncheon meat
- Tuna and seafood
- Ready meals
- Pet wet food
Wellfa now exports retort packaging to South America, Europe, and Asia, supporting brands of all sizes with stable quality and customized solutions.
A Smart Alternative to Cans
Compared with traditional cans, retort pouches offer clear advantages:
- Much lighter weight
- Lower transport and storage costs
- Faster heat transfer during sterilization
- Better shelf appearance and branding space
- More convenient for consumers
For many products, retort pouches are a smarter, more flexible packaging choice.
Built for 121–135°C Sterilization
Quality has always been our top priority.
Our retort pouches are designed to withstand 121°C to 135°C sterilization, using:
- Professional-grade retort adhesives
- High-temperature-resistant inks
- Carefully selected multilayer structures
All materials are FDA and EU food-contact approved, with full testing reports available.
Innovation: ALOXPET as an Alternative to Aluminum Foil
To improve barrier performance while meeting growing recyclability and sustainability demands, Wellfa has developed ALOXPET-based retort structures as an alternative to traditional aluminum foil.
ALOXPET offers:
- High oxygen and moisture barrier (similar to aluminum foil)
- Better transparency and flexibility
- Improved recyclability potential
- Stable performance at 121–135°C retort conditions
This innovation allows brands to move toward high-barrier, more eco-friendly retort packaging without sacrificing safety.
