What Are The Common Materials Used For Food Packaging Boxes?

Food packaging boxes are ubiquitous in daily life. They not only protect food but also enhance its appeal. Different foods require different packaging materials. Below are some common materials used for food packaging boxes.

Paper Materials

1. White Cardboard: White cardboard is a type of cardboard with a smooth, white front and a gray back. It has good stiffness and folding resistance, and good printability. Many small food items, such as biscuits and candies, often use white cardboard for their packaging boxes. White cardboard can be printed with beautiful patterns and text in color, thus improving the product's visual appeal. Moreover, white cardboard is relatively environmentally friendly, easy to recycle, and meets the modern consumer demand for green packaging.

2. White Cardboard: White cardboard has high whiteness, a clean white color, and a sturdy and thick texture. It has good strength and toughness, and good water resistance. Some high-end foods, such as chocolate and high-end pastries, choose white cardboard as their packaging material. White cardboard effectively maintains the shape of packaging boxes, preventing food from being squeezed and deformed during transportation and storage. Its smooth surface also allows for clearer and more vibrant printed designs, enhancing the product's perceived quality.

3. Corrugated Cardboard Corrugated cardboard is made by bonding linerboard to corrugated paper formed by corrugating rollers. It is lightweight, provides good cushioning, and is low-cost. For foods that require long-distance transportation or are easily impacted, such as fruits and eggs, corrugated cardboard boxes are an excellent choice. The corrugated structure of the cardboard acts as shock absorber and cushioning, protecting food from damage. Furthermore, corrugated cardboard can be printed to display product information and brand logos.
