With the continuous improvement of people's living standards, the requirements for high quality and diversification of food and its packaging are also getting higher and higher. Cup-packed yogurt has gradually penetrated into people's lives. Yogurt packaging must not only have good barrier properties, but also ensure product quality. Moreover, while improving the grade of yogurt products, it is also necessary to ensure the convenience of opening for consumers. kk Aluminum's 8011 heat sealing foil has good surface quality, flat shape and small thickness tolerance. It is the preferred material for yogurt heat sealing packaging. The products are exported to domestic and foreign markets and have won unanimous praise!
The composition of dairy products is complex and easily affected by temperature, oxygen, light, microorganisms, mechanical effects, etc., resulting in discoloration, oxidation, damage, and deterioration of their products, thereby shortening the shelf life.
Large enterprises now use aluminum foil to seal dairy products, which has the following advantages:
(1) The sealing performance of aluminum foil is better than that of pure plastic. When looking at the plastic material under a magnifying glass, there are actually many small holes, and air and water can pass through;
(2) The strength of the aluminum foil composite film is high;
(3) The third is the sealing process. Yogurt generally adopts 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 are glued 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;
The performance of kk aluminum 8011-O state aluminum foil is superior, and the characteristics are as follows:
1. The surface is clean, uniform in color, no spots, flat and no holes;
2. It has excellent moisture-proof performance, shading and high barrier ability;
3. Bacteria, mold and other tests, non-toxic, tasteless, safe and hygienic;
4. Strictly implement industry standards, and heavy metals do not exceed the specified range;
5. Strong mechanical properties.
