With people's increasing emphasis on pet health, the demand for pet food packaging is also constantly changing. The packaging of pet food should not only protect the food from contamination, but also extend its shelf life, prevent waste, and have aesthetic appeal to attract consumers. Aluminum easy to open lids have become one of the preferred materials for pet food canned packaging due to their excellent sealing performance.
Aluminum easy to open lids are usually made of tinplate material, which has good sealing performance and can effectively isolate external pollution, ensuring the freshness and nutritional value of food. In addition, aluminum easy to open lids also have certain strength and toughness, which can withstand the pressure during transportation and storage
Easy to open aluminum alloy plates require high dimensional accuracy and good surface quality, with a thickness tolerance of ± 0.005 millimeters and a width deviation of+1.0-0. In addition, high strength, good formability, and uniform performance are required.
1. The thickness range of aluminum alloy plate for cover is 0.208-0.360mm
2. The width range of aluminum plate for can lid is 800-1730mm
1. Common alloys and states for cover materials include 3104-H19 aluminum coil, 5052-H19 aluminum coil, etc
2. The commonly used materials for pull rings include 5182, and the thickness and alloy state of the aluminum plate used depend on the form of the pull ring and the alloy of the cover material used.
