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.

Semi Retort Film FAQ

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.
