The function of packaging

Protection function

Snack foods often have different shapes, textures and compositions. Packaging to prevent food in the transportation, storage and sales process by physical damage, such as potato chips are easy to break, through the use of strong packaging materials, such as multi-layer composite potato chip bags, can effectively buffer the external pressure.

At the same time, the packaging can resist chemical changes. For example, some snack foods containing fats are prone to oxidation and rancidity, and suitable packaging materials (such as aluminum foil) can block oxygen and extend the shelf life of the food. In addition, the packaging can also prevent the food from being damp, like the desiccant package in the biscuit packaging, which can absorb the excess water in the packaging and maintain the crispy taste of the biscuit.

Convenient function

Leisure food packaging design focuses on the convenience of consumers. For example, independent small packaging of nuts, convenient for consumers to carry and eat at any time, whether it is outdoor travel or work in the office, can easily open the package to enjoy.

The design of easy tear mouth is also a common convenient function embodiment. Like some soft-packaged dried meat, easy-to-tear openings are set on the edge of the package, and consumers can easily open the package without the aid of tools.

Promotion function

Packaging is an important factor in attracting consumers to buy snack foods. Brightly colored and beautifully patterned packaging can stand out on the shelf. For example, many children's snack food packaging uses bright colors and cartoon images to attract children's attention.

The text information on the packaging can also play a promotional role. The characteristics of the product, taste (such as "rich chocolate flavor"), raw material advantages (such as "selected high-quality wheat") and other slogans can attract consumers to try to buy.
