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.

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.
