Aluminum foil is a material with good formability and a certain degree of rigidity, making it ideal for manufacturing semi rigid containers. Semi rigid containers use aluminum foil as the main body and are formed into boxes, shallow trays, and other semi-rigid containers through molding processes. Primarily processed through stamping, aluminum foil is formed into various shapes of semi rigid containers, such as lunch boxes, bowls, and cups. These containers have a fixed shape, can withstand certain external forces, and remain lightweight and aesthetically pleasing.

Specification of aluminum semi rigid container foil:
- Alloys:
Common alloys of aluminum semi rigid container foil include 8011 aluminum foil, 3003 aluminum foil, and 3004 aluminum foil.
- Tempers:
Mostly O temper (soft), H22, and H24. O temper aluminum foil has good flexibility and ductility, facilitating stamping, while H22 and H24 tempers have a certain degree of hardness and strength, allowing the finished containers to maintain their shape well.
- Thickness：
Typically between 0.02-0.2mm, and width is generally 150-1300mm, but can be customized according to different production needs.
- Applications:
Mainly used for food packaging, such as fast food restaurant and takeout containers, baking trays and bowls for home kitchens, and also for packaging pharmaceuticals and cosmetics.

Performance characteristics of aluminium semi rigid container foil:
- Excellent barrier properties:
Effectively blocking oxygen, moisture, and light, protecting the quality of the contents.
- Good chemical stability:
not easily reacting with food, and non-toxic and odorless, meeting food hygiene standards.
- Good thermal conductivity:
Suitable for microwave heating or refrigeration.
- Strength:
Aluminum foil for containers needs to possess certain tensile and tear strength to ensure it does not easily break or deform during processing and use.
- Formability:
Aluminum foil should have good formability, able to be pressed, folded, or shaped into the desired container shape during manufacturing.
- Corrosion resistance:
Aluminum itself has good corrosion resistance, effectively protecting the food or other items inside the container from external environmental influences.

Features of the semi rigid containers made from aluminum foil:
- Excellent barrier properties:
Aluminum foil has excellent light, oxygen, and moisture barrier properties, effectively preventing food oxidation and spoilage, and extending shelf life.
- High temperature resistance:
Semi-rigid aluminum foil containers can withstand high temperatures, making them suitable for baked, heated, and frozen foods. They are microwave and oven safe.
- Lightweight and portable:
These containers are lightweight and easy to carry, making them ideal for takeout and convenience food packaging.
- Environmentally friendly and recyclable:
Aluminum is recyclable, meeting modern environmental requirements and reducing environmental impact.
- Versatile design:
Semi-rigid aluminum foil containers can be designed in different shapes and sizes to meet the packaging needs of various foods.

Applications of aluminum semi rigid containers:
Ready-to-eat meals: Such as fast food and bento boxes, allowing consumers to enjoy them quickly.
Baked foods: Such as cakes and pies, suitable for direct use after baking.
Frozen foods: Suitable for storing frozen foods, such as ice cream and frozen meat.
Takeout foods: Due to their excellent sealing and temperature resistance, they are widely used in the takeout industry.
