(1) The sealing performance 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;
(2) The aluminum foil composite film has high strength;
(3) The third is the sealing process. Yogurt generally uses heat sealing. In principle, it is to use a piece of hot iron to iron the sealing film and the bottle mouth, so that the sealing film and the bottle mouth are heated and melted and then stick together. To achieve the sealing effect, aluminum foil is more resistant to high temperatures and has better sealing effect;
8011-O aluminum foil has superior performance and its characteristics are as follows:
1. The surface is clean, even in color, no spots, smooth and without holes;
2. It has excellent moisture-proof performance, light-shielding and high barrier ability;
3. Multiple tests for bacteria, mold, etc., non-toxic, tasteless, safe and hygienic;
4. Strictly implement industry standards, and heavy metals do not exceed the specified range;
5. Strong mechanical properties.
