Aluminum-plastic material is a packaging material that uses a composite structure of aluminum and plastic, combining the high quality moisture-proof and light-shielding properties of aluminum with the heat-sealing properties of safety-grade plastic material, which is widely used in the food, pharmaceutical, and cosmetic fields.
Ⅰ.Specific advantages of aluminum-plastic packaging materials
First of all, the aluminum-plastic material has high strength and durability. The properties of aluminum make the bags more robust and durable, not easy to be torn or broken, and can effectively protect the packaged items from external damage. At the same time, the flexibility of plastic makes the bags have better pressure resistance and are not easy to deform.
Secondly, the aluminum-plastic material has excellent light-blocking and moisture-proof performance. The presence of the aluminum layer effectively isolates the entry of air and moisture, preventing the packaged items from moisture or deterioration. This is very important for some items such as tea, coffee beans, etc.. Some products need to be stored away from light, where the aluminum layer plays a crucial role, such as pharmaceuticals.
In addition, the aluminum-plastic repackaging bags also have good anti-oxidation performance. The aluminum layer can block the entry of oxygen, effectively slowing down the oxidation rate of the packaged items and maintaining their freshness and quality. This is an important protection for some easily oxidized items, such as edible oils, cosmetics and so on. This performance can ensure that the shelf life of the product can reach more than one year.
Overall, the emergence of aluminum-plastic composites has brought more options and possibilities to the packaging industry. Its excellent performance has made it the packaging material of choice for many industries. Whether it is to protect the product or to increase the added value of the product, aluminum-plastic material can play an important role.
Next, let’s take aluminum plated pouches and aluminum foil lids as examples to see the advantages of this material’s application.
Ⅱ.Aluminum plated pouches
Aluminum plated pouches, have an indispensable role in our daily lives. We can often see candy, dried fruit and other food packaging to this bag, both quality assurance performance and to show customers the appearance of the product. Some brands will design a beautiful appearance, design a small transparent window in the front of the bag to show customers the product in the bag.
As a kind of functional packaging bag, it is widely used in many fields such as food, medicine, electronic products and so on, with its unique performance and advantages, it brings great convenience to our life.
Aluminum plated pouches are usually composed of aluminum foil and plastic film, a combination that gives it a metallic luster and high barrier properties. Metallic luster not only makes the package appearance more beautiful, enhancing the grade and attractiveness of the product, but also can effectively reflect the light and reduce the damage of light to the items inside the package. The high barrier is another major feature of aluminum plated bags, it can effectively block the penetration of oxygen, water vapor and other substances, to protect the contents of the package from the influence of the external environment.
In addition to the advantages in appearance and performance, aluminum plated pouches are also high temperature resistant, lightweight and soft, and environmentally friendly and recyclable. The specific structure can withstand processing such as high temperature steaming, so it can be used for the packaging of food and medicine. At the same time, the material of aluminum plated pouches is lightweight and soft, which can reduce the weight of the package and make it easy to transport and use.
In the field of food packaging, aluminum plated pouches are especially widely used. Whether it is puffed food, candy or dried fruit, etc., you can see them. It can effectively protect food from oxygen and water vapor, maintaining the taste and nutritional value of food. At the same time, aluminum plated bags can also prevent food from moisture and oxidation, extending the shelf life of food. This makes consumers feel more at ease when buying food and promotes the healthy development of the food industry.
In the field of pharmaceutical packaging, aluminum plated pouches also play an important role. The environmental requirements of drugs are very high, once the moisture or oxidation, the efficacy and safety of medicine will be seriously affected. Aluminum plated pouches can effectively prevent drugs from moisture and oxidation, and maintain the stability and effectiveness of drugs. In addition, the aluminum plated pouches can also avoid the drugs to be polluted and damaged by the external environment, to ensure the safety and hygiene of the drugs.
In addition to food and drug packaging, aluminum plated pouches also have a wide range of applications in the field of electronic product packaging. With the continuous development of science and technology, electronic products have become an indispensable part of our lives. However, electronic products for the environment is also very sensitive to the degree of high, once the interference of the external environment and damage, its function and service life will be affected. Aluminum plated pouches can effectively protect electronic products from the interference and damage of the external environment, to maintain their appearance and functional integrity.
In addition, aluminum plated pouches can also be applied in many fields such as daily necessities and cosmetics. For example, in cosmetic packaging, aluminum plated pouches can effectively protect cosmetics from light and oxygen, maintaining their quality and effect. In the packaging of daily necessities, aluminum plated pouches can prevent moisture and oxidation and prolong the service life of daily necessities.
Ⅲ. Aluminum foil lids
In fact, the sealing aluminum foil lids is also an aluminum-plastic composite structure that combines the excellent properties of aluminum foil with heat-sealable plastic for different containers. Aluminum foil lid is a material with good freshness preservation performance. It can effectively insulate the outside world from oxygen, moisture and bacteria, preventing yogurt from contamination and oxidative deterioration. In addition, aluminum foil also has certain moisture-proof performance, which can prevent yogurt from being affected by moisture, thus prolonging its shelf life.
Light-proof performance of aluminum foil: Yogurt contains certain components such as milk protein and lactose, which are easily affected by light. Therefore, in order to ensure the quality and taste of yogurt, yogurt packaging must have certain light-proof performance. Aluminum foil lid has good light-proof performance, which can effectively prevent the influence of light and ensure the quality and taste of yogurt.
Aluminum foil’s barrier performance: the lactic acid bacteria in yogurt need a certain amount of oxygen to ferment and grow. However, too much oxygen in yogurt packaging will lead to spoilage and corruption of yogurt. Therefore, in order to ensure the quality and taste of yogurt, yogurt packaging must have a certain oxygen barrier performance. Aluminum foil has good anti-oxidation performance, which can effectively prevent the invasion of oxygen and keep the freshness and taste of yogurt.
