Retort pouches are versatile for various food types and offer superior consumer convenience, with studies showing lower bacteria levels in vacuum-sealed pouches. With 15 years of packaging expertise, CWL PACK provides superior flexible packaging solutions.
Benefit 1: Extended Shelf Life
High-barrier films and sterilizing technology are combined in retort pouches to accomplish：
- 24-36 months shelf life
- Oxygen transmission rate <0.5 cc/m²/day
- Water vapor barrier ≤1.5 g/m²/day
CWL Solution：Our retort pouch—comprising an ALOX-PET surface layer, an NY composite layer, and an RCPP inner layer—has successfully passed the 121°C sterilization test, making it ideal for pet food and ready-to-eat meals.
Benefit 2:Lightweight and Space-Efficient
Due to their notable lightweight and compact design, retort pouches are a great option for both consumers and producers. Because of their lighter weight, they have a less negative impact on the environment and transportation costs, and their space-efficient form makes it simpler to store them in homes and stores. This feature is especially helpful for outdoor pursuits like trekking and camping, when weight and space are important factors.
Compared to traditional packaging:
| Metric | Cans/Jars | Retort Pouches | Improvement |
|---|---|---|---|
| Weight/500g capacity | 380g | 45g | 88%↓ |
| Transport space utilization | 62% | 91% | 47%↑ |

Benefit 3:Enhanced Food Quality Preservation
Retort pouches provide a very strong barrier against contamination, which is a major benefit when it comes to food preservation. Food is exposed to less air, moisture, and germs since these pouches are vacuum-sealed after processing. Retort pouch packaging keep oxygen away from the foodstuff, which inhibits microbial development and lessens oxidative degradation. This keeps the food's flavor, aroma, and nutritional content intact.
For example, compared to conventional canning techniques, a study published on Packaging World showed that vacuum-sealed retort pouches dramatically reduce the bacteria counts in ready-to-eat meals. Food safety and quality preservation depend on the food staying uncontaminated until the pouch is opened, which is ensured by this controlled environment.
Benefit 4:Versatility in Food Applications
Because of their versatility, retort pouches may hold a variety of food items, such as solid foods, soups, stews, and sauces. Because of its resistance to high temperatures during the retort process, a wide range of food kinds can be safely packaged to accommodate different dietary requirements and consumer preferences. They are a great choice for food manufacturers wishing to diversify their product lines because of their adaptability.
| Food type | Technical parameters | Application cases |
|---|---|---|
| Liquid (soup/sauce) | Hydraulic pressure resistance ≥ 0.3MPa | Anti-leakage seal Pasta sauce brand annual sales + 54% |
| Semi-solid (stew/curry)） | Four-layer gusseted anti-bulging bag | Southeast Asian instant curry market share 22% |
| Solid (meat/vegetables) | Puncture resistance ≥ 8kg (ASTM F1306) | Outdoor freeze-dried food damage rate ↓ 89% |
