The appearance of aluminum foil bags has made a huge contribution to the flexible packaging industry. With its excellent characteristics, aluminum foil bags have been widely used in the food packaging industry. Aluminum foil bag packaging usually refers to aluminum-plastic composite vacuum packaging bags. These products are suitable for moisture-proof, light-proof and vacuum packaging of large-scale precision machinery and equipment, chemical raw materials and pharmaceutical intermediates.
1. Shell maintenance
The outer casing can separate food from oxygen, water vapor, stains, etc., and leakage prevention is also a required component of packaging design. Some packages include a desiccant or a deoxidizer to extend the shelf life. Vacuum packaging or air drawn into the bag is also the primary food packaging method. Keeping the food clean during the warranty period, novelty and safety are the primary functions of the package.
2. Physical maintenance
The food stored in the bag is protected from squeezing, impact, vibration, temperature difference and the like.
3. Package or load the same package
It is a good way to reduce the volume of a small item of the same variety into a package. Powders and granular objects are required to be packaged.
4. Communicate information
Packaging and labeling inform people how to use packaging, food, take over or dispose of it.
Although aluminum foil bags have such a wide range of applications, they are well received by the market. However, in actual production and application, it is also crucial to determine the material selection and process problems of aluminum foil bags according to different industry products.
