Semi-rigid aluminum foil for containers is a kind of aluminum foil material that has been specially processed. It has high mechanical strength and good corrosion resistance, and is very suitable for making containers that require a certain hardness and stability. It is widely used in many fields such as food, medicine, construction and automobiles.

Advantages of food-grade aluminum foil for semi-rigid containers:
1. Good formability, maintaining structural stability
2. High strength, not easy to deform or crack
3. Corrosion resistance, resistance to acid and alkali components in food
4. Recyclable, conducive to environmental protection
5. High barrier properties, extended shelf life
6. High and low temperature resistance, no deformation or cracking
7. Lightweight, easy to transport and store
Production process of aluminum foil for semi-rigid containers:
1. Raw material preparation
Main raw material: aluminum ingot
Melting: Aluminum ingots are melted into liquid aluminum in a furnace.
2. Rolling Process
Rolling Mill Processing: Liquid aluminum passes through a series of rollers in the rolling mill, where it is flattened and spread into thin sheets under high pressure.
3. Annealing Process
Heating: The aluminum sheet is heated to a specific temperature through an annealing furnace to soften the aluminum and make it more ductile.
Cooling: After heating for a few minutes, the sheet cools slowly, making it stronger and more durable.
4. Lubrication Process
Lubrication: After the annealing process, the aluminum sheet is lubricated to improve the surface quality and prevent it from sticking to the machine.
5. Aluminum Foil Forming
Cutting and Punching: The aluminum sheet is cut into small pieces and punched and formed into the required semi-rigid container shape through a die.
6. Quality Inspection
Inspection Content: The processed aluminum foil is subject to quality inspection on parameters such as thickness, size, strength and durability to ensure that it meets the required quality standards.
7. Packaging and Delivery
Packaging: After passing the quality inspection, the aluminum foil will be packaged.
Delivery: The packaged aluminum foil is delivered to the customer's location.
