Barrier plastic composite flexible packaging materials are used in a wide range of fields, such as vacuum packaging, displacement air packaging, etc., in principle, aluminized barrier films can basically be applied. Compared with ordinary all-plastic barrier films, aluminized barrier films have their own characteristics and unique features in some applications, which must be paid attention to. So what are the fields where the aluminized barrier film is used, and Nanjing Sumino Seiko will introduce it to you today:
1. Main advantages of aluminized barrier film
The difference between the aluminized barrier film and the ordinary all-plastic barrier film is mainly reflected in the following aspects.
First of all, aluminized barrier films do not have transparency, so naturally they cannot be used in packaging that requires transparency.
Secondly, the aluminum-plated barrier film, because it contains an aluminum-coated layer, cannot pass through microwaves, so it cannot be used for microwave food packaging.
Furthermore, the thickness of the aluminum-coated layer of the aluminum-coated barrier film is very thin. At present, the maximum thickness reported in the literature is no more than 0.1 ¦Ìm. If stretch packaging is used, the aluminum-coated layer may be thinned during the stretching process, resulting in barrier properties. Significantly decreased, losing the barrier properties to oxygen and water vapor, so it is not suitable for stretch packaging. www.susumino.comNanjing Susumo Seiko professional casting machine laminating machine equipment manufacturing
Compared with ordinary all-plastic barrier films, aluminum-coated barrier films have good barrier properties to visible light and ultraviolet rays, so they have good protection functions for substances that are easily damaged by light and ultraviolet rays, and can extend their shelf life. Therefore, it is suitable for the packaging of photosensitive foods, medicines, and commodities containing photosensitive ingredients. The effect is better than ordinary all-plastic barrier packaging film. www.susumino.comNanjing Susumo Seiko professional casting machine laminating machine equipment manufacturing
2. Application of aluminized barrier packaging film
Aluminum-plated barrier film has become a mature product of composite flexible packaging materials, and has been widely used in the packaging of many commodities represented by food and medicine. Specific application examples can be listed as follows: processed vegetables such as pickled mustard and pickles packaging of tea, coffee and other commodities; packaging of condiments such as ketchup; packaging of milk powder, milk, cheese, cream and other dairy products; packaging of tablets; packaging of pesticides; rice, noodles, instant noodles, pancakes, potato chips, Packaging of snacks; packaging of meat floss, fish floss, sausage and other processed foods; packaging of candy, candied fruit, chocolate; jelly packaging. www.susumino.comNanjing Susumo Seiko professional casting machine laminating machine equipment manufacturing
The above list are only a few examples of the application of barrier aluminum-coated flexible packaging materials. In fact, as long as the products that need to block oxygen, moisture, moisture, fragrance, and prevent visible light and ultraviolet light, barrier coating can be considered.
