Top China Aluminum Foil Company
In our lives, we often see small bottles or cups of yogurt in supermarkets, and we often buy this yogurt. But have you noticed what its packaging lid looks like?
In fact, the choice of sealing materials for plastic cups of yogurt is very important. It is necessary to consider the protective effect of yogurt and the convenience of consumers to open and drink. 8011 aluminum foil and 8079 aluminum foil have these characteristics and become common materials for yogurt lids. The yogurt cup is sealed with aluminum foil, which can be airtight, moisture-proof and shading. At the same time, the aluminum foil is hygienic and easy to open.
And we all know that the shelf life of yogurt is very short, and there is no way to store yogurt for a long time at a very early stage, so many yogurt manufacturers will face the problem of yogurt being dumped because of its expiration date.
Many people try to find a way to preserve yogurt for a long time. After unremitting efforts, I finally found a way. Researchers have discovered that a material can be used as a packaging material for food, and the material packaged through it can make the shelf life of the food longer.
Therefore, this material was also applied to the packaging of yogurt, and it was successful after many trials. This material is aluminum foil. Its airtightness is better than pure plastic. When viewed under a magnifying glass, the plastic material actually has many small holes through which air and water can penetrate.
And its heat sealing performance is very good. 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 stick together after being heated and melted. To achieve the sealing effect, the aluminum foil is more resistant to high temperature and the sealing effect is better.
