Aluminum Foil Roll 8011 O Soft In Yogurt Packaging And Sealing

Why do small cups of yogurt have to be sealed with aluminum foil?
First of all, the airtightness of aluminum foil is better than that of pure plastic. When viewed under a magnifying glass, the plastic material actually has many small holes, through which air and water can pass. Second, the aluminum foil composite film is strong. The third is the sealing process. The yogurt generally uses heat sealing. In principle, a piece of hot iron is used to iron the sealing film and the bottle mouth, so that the sealing film and the bottle mouth will be stuck together after being heated and melted to achieve a seal. Effect, the aluminum foil is more resistant to high temperature, and the sealing effect is better
 
The yogurt cup cover film is mostly made of aluminum foil composite film material, mainly to ensure the high barrier properties of the seal, and at the same time to meet the easy puncture of the straw. However, if the cover film is too easy to puncture, it will not tolerate the force of external hard objects, resulting in quality problems such as leakage and damage. Therefore, how to ensure that the puncture resistance of the cover film is more appropriate requires professional puncture resistance testing equipment and reasonable testing methods for verification.
 
Plastic cups of yogurt packaging often use a metal film containing aluminum foil as the lid film, that is, a composite film formed by aluminum foil and other plastic films.Because Yogurt contains a lot of fat and protein components, and its packaging materials are required to have high oxygen barrier properties, and the covering film of this material has high barrier properties. properties, which can ensure excellent oxygen barrier properties of the yogurt cup; at the same time, it is easy to be punctured by the straw , It is convenient for the eater to suck, but it does not mean that the puncture resistance of the cover film is as small as possible (that is, the cover film is easy to pierce), and a certain puncture resistance must be met to prevent accidental damage caused by external objects
