Tloušťka hliníkové fólie pro balení potravin je obecně mezi 0.015-0.03 mm. Přesná tloušťka hliníkové fólie, kterou zvolíte, závisí na typu balených potravin a požadované trvanlivosti.
Pro potraviny, které je třeba skladovat po dlouhou dobu, doporučuje se zvolit silnější hliníkovou fólii, jako 0.02-0.03 mm, pro lepší ochranu před kyslíkem, voda, vlhkost a ultrafialové paprsky, 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, atd., you can choose thinner aluminum foil, such as 6μm,13(6mikronová hliníková fólie, 13mikrofonní hliníková fólie) hliníková fólie. 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 na 9 mikronů) 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 na 12 microns may be appropriate. This thickness provides a good balance between strength and flexibility.
Heavy-Duty Packaging: Thicker aluminum foil (approximately 12 na 15 mikronů) 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.
Navíc, 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.
