Unene wa foil ya alumini kwa ufungaji wa chakula kwa ujumla ni kati 0.015-0.03 mm. Unene halisi wa karatasi ya alumini unayochagua inategemea aina ya chakula kinachowekwa na maisha ya rafu unayotaka..
Kwa chakula kinachohitaji kuhifadhiwa kwa muda mrefu, inashauriwa kuchagua foil nene ya alumini, kama vile 0.02-0.03 mm, kutoa ulinzi bora dhidi ya oksijeni, maji, unyevu na mionzi ya ultraviolet, thereby protecting the nutrients of the food from being destroyed and extending the shelf life of the food. Shelf. For short-term preservation of food, such as candy, chokoleti, nk., you can choose thinner aluminum foil, such as 6μm,13(6karatasi ya alumini ya micron, 13karatasi ya alumini ya maikrofoni) karatasi ya alumini. It is thin and transparent, which can better fit the food and reduce the penetration of oxygen and moisture. Thereby extending the shelf life of food.
Lightweight Packaging: For packaging lightweight foods or covering cutlery, thinner aluminum foil (approximately 6 kwa 9 mikroni) is sufficient. This thickness provides flexibility and ease of use.
Medium packaging: For packaging medium-weight items such as sandwiches, baked goods, or individually wrapped foods, aluminum foil with a thickness of approximately 9 kwa 12 microns may be appropriate. This thickness provides a good balance between strength and flexibility.
Heavy-Duty Packaging: Thicker aluminum foil (approximately 12 kwa 15 mikroni) is recommended for heavier or sturdier foods, such as roasts, meats, or foods that require long periods of storage or cooking. This provides extra strength and durability to withstand handling and cooking processes.
Aidha, the material and quality of aluminum foil are also factors that need to be considered when selecting. High-quality aluminum foil should have good corrosion resistance, high temperature resistance and mechanical strength to ensure food safety and hygiene.
