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. The composition of dairy products is complex and easily affected by factors such as temperature, oxygen, light, microorganisms, etc, resulting in discoloration, oxidation, damage, and deterioration of their products, thereby shortening the shelf life. Therefore, the selection of packaging materials for dairy products is relatively strict. In order to reduce the influence of external factors, aluminum foil composite film is generally used for the sealing of yogurt cups.
Cup yogurt cover film is made of aluminum foil composite material. 8011 aluminum foil is mostly used. 8011-o state aluminum foil is very soft, non-toxic, tasteless, safe and hygienic, with clean surface and uniform color, which is very suitable for making yogurt cover. After the 8011 aluminum foil is compounded with other materials, the strength is improved, and its sealing effect is better than that of pure plastic. The yogurt sealing process generally adopts heat sealing, so that the sealing film and the bottle mouth are melted by heat and stick together to achieve the sealing effect. The aluminum foil is more resistant to high temperature and has a better sealing effect.
The yogurt cover film is mainly made of composite materials, and the structure is polyester/aluminum foil/heat sealing layer (PET/AL/PE·EVA). 8011-o state aluminum foil is very soft, has excellent moisture resistance, light shading, and high barrier ability, which can prolong the storage time of yogurt.
Advantages of 8011-O milk cover foil:
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. Non-toxic, tasteless, safe and hygienic;
4. Strong mechanical properties, high blast resistance, puncture resistance and tear resistance.
The 8011-O state aluminum foil raw material produced by MC Aluminum is widely used in yogurt sealing film. The 8011-O state aluminum foil has few pinholes, good barrier properties and heat sealing performance, and the product is degreasing clean, the surface is clean, the product reaches food grade, can be High temperature cooking, safe and hygienic, you can buy with confidence.
