Semi Retort Film
Semi-retort film is a CPP film that falls between regular packaging film and retort film, offering excellent heat resistance and flexibility. It is primarily used for food products that do not require high-temperature, high-pressure sterilization but need some heat treatment, such as cooked foods, marinated foods, and fruit and vegetable products.

FAQ About Semi Retort Film
Q: What is the difference between Semi Retort Film and Retort Film?
A: Semi Retort Film has higher heat resistance than ordinary packaging film, but slightly lower than Retort Film, and is suitable for foods that do not require such high sterilization temperature.
Q: How to choose the right Semi Retort Film?
A: You can choose the right thickness and surface treatment according to the characteristics of the product, packaging requirements and budget.
Q: Is Semi Retort Film suitable for all types of food?
A: Semi Retort Film is suitable for most types of food, but for some highly acidic foods, certain chemical reactions may occur, so corresponding tests are required.
Q: How to choose a suitable Semi Retort Film supplier?
A: When choosing a supplier, you should consider factors such as the supplier’s production experience, quality control system, and after-sales service.
