O grosor da folla de aluminio para envases de alimentos é xeralmente entre 0.015-0.03 mm. O grosor exacto da folla de aluminio que elixe depende do tipo de alimento que se envasa e da vida útil desexada..
Para alimentos que necesitan ser almacenados durante moito tempo, recoméndase escoller papel de aluminio máis groso, como 0.02-0.03 mm, para proporcionar unha mellor protección contra o osíxeno, auga, humidade 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(6papel de aluminio micron, 13papel de aluminio para micrófono) papel de aluminio. 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 (Aproximadamente 6 a 9 micras) 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 a 12 microns may be appropriate. This thickness provides a good balance between strength and flexibility.
Heavy-Duty Packaging: Papel de aluminio máis groso (Aproximadamente 12 a 15 micras) is recommended for heavier or sturdier foods, such as roasts, carnes, or foods that require long periods of storage or cooking. This provides extra strength and durability to withstand handling and cooking processes.
Ademais, 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.
