Common Packaging Box Inserts: A Manufacturer’s Overview

When customizing packaging boxes, many people face the question of which material is most suitable for the box inserts. Here’s a brief summary of six commonly used packaging box inserts:

1. Plastic Inserts (Blister Inserts)
Blister inserts are formed using vacuum-forming techniques. These inserts serve multiple purposes: providing support, protection, shock absorption, separation, fixation, and enhancing the appearance of the product.

2. Foam Inserts
Foam is a commonly used, cost-effective material with excellent shock absorption. It is ideal for packaging fragile items like glassware that require high levels of protection.

3. Cardboard Inserts
Cardboard or corrugated paper is widely used due to its low cost and ease of processing. It is best suited for items with regular shapes, such as square or rectangular objects.

4. Sponge Inserts
High-density sponge inserts are known for their excellent elasticity and softness. They maintain their shape even after long use, providing a comfortable and durable option that won’t deform or collapse.

5. EPE Foam Inserts (Expanded Polyethylene)
EPE foam is a higher-end material compared to regular foam. It is less prone to crumbling, making it a popular choice for electronic products. However, it is more expensive than foam.

6. EVA Inserts
EVA (Ethylene Vinyl Acetate) foam is a dense, high-quality material available in black and white. Depending on the EVA content, the quality varies. It is often more visually appealing than PE foam, can be used directly, and can be molded into various shapes. Many packaging boxes now use EVA for inserts due to its versatility.

These inserts are chosen based on the product’s needs, balancing cost, protection, and presentation.
