A freezer separator liner is for use when wrapping foods for freezing including chops, hamburgers, fish, cheese and dessert slices. Its non-stick and waterproof nature keeps individual portions easily accessible and provides a barrier to air and moisture to maintain the quality, flavour and nutrition of foods whilst frozen. The sheet can be cut to any required size. It is reusable and is suitable for temperatures as low as -70°C. The sheet measures 100cm by 15cm and is dishwasher safe.
