A espessura da folha de alumínio para embalagens de alimentos está geralmente entre 0.015-0.03 milímetros. A espessura exata da folha de alumínio que você escolher depende do tipo de alimento embalado e do prazo de validade desejado..
Para alimentos que precisam ser armazenados por muito tempo, recomenda-se escolher uma folha de alumínio mais espessa, como 0.02-0.03 milímetros, para fornecer melhor proteção contra oxigênio, água, umidade e raios ultravioleta, 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, chocolate, etc., you can choose thinner aluminum foil, such as 6μm,13(6folha de alumínio de mícron, 13folha de alumínio de microfone) folha de alumínio. 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 para 9 mícrons) 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 para 12 microns may be appropriate. This thickness provides a good balance between strength and flexibility.
Heavy-Duty Packaging: Thicker aluminum foil (approximately 12 para 15 mícrons) 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.
Além disso, 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.
