Aluminum Foil Food Packaging for Chocolate

Due to the characteristics of chocolate itself, it is required to prevent moisture absorption and melting, aroma dissipation, oil precipitation and rancidity, pollution and heat during packaging. Therefore, the requirements for chocolate packaging materials are very strict, which not only ensures the beauty of the packaging, but also meets the above packaging requirements. The packaging materials of chocolate on the market mainly include paper packaging, aluminum foil packaging, tin foil packaging, plastic flexible packaging and composite material packaging.

1. Paper packaging

Due to the high environmental protection of paper products, they are generally used for the outer packaging of chocolate. The outer packaging uses a fixed paper box to protect the chocolate from damage and enhance the display.

2. Aluminum foil packaging

Aluminum foil for chocolates has the characteristics of moisture-proof, light-proof and heat-insulating. Whether the inner or outer packaging of chocolate, there must be a shadow of aluminum foil. Generally, aluminum foil is used as the inner packaging of chocolate. Chocolate is a food that is easy to melt, and aluminum foil can effectively ensure that its surface does not melt.

3. Tin foil packaging

This is a traditional packaging material. Because of its good barrier and ductility, it has always occupied a place in the current chocolate packaging. However, it is greatly impacted by plastic packaging due to factors such as production process, production efficiency, application limitations and price.

4. Plastic packaging

Plastic packaging has become one of the most important packaging materials for chocolate with its rich functions and diverse display. With the maturity of technology, cold-sealed soft packaging has gradually become the most important inner packaging material for chocolate due to its advantages of high packaging speed, low odor, no pollution, easy tearing, and the ability to avoid the influence of high temperature during chocolate packaging.

These are the common packaging design materials for chocolate. Currently, most chocolates use aluminum foil food packaging. This is because the raw materials of chocolate contain cocoa butter. Cocoa butter will react with moisture and oxygen in the air, and the smell and taste of chocolate will be lost. Aluminum foil has the characteristics of being impermeable and airtight, which can prevent the aroma of chocolate from overflowing and prevent external odors from mixing in.

At the same time, aluminum foil can also physically isolate chocolate from insects, and has a good insect-proof effect. In addition, aluminum foil is easy to fold, so using aluminum foil is convenient for wrapping and peeling. Most aluminum foils for food packaging are made of 8011 aluminum foil, featuring low cost and stable chemical properties.
