When designing shipping boxes, there is usually some space allowance given between the item and the interior walls of the box. This space is not usually big, particularly with custom boxes. But it is necessary to provide space for packaging materials that will help provide added protection. These materials help to absorb shock and prevent the contents from shifting around. This padding is also important in case the box is perforated. There is less risk the product will be damaged. Here are some of the best options in interior packaging.
This is probably the most stable option for products. The foam material is typically quite rigid yet lightweight, providing an effective way for products to remain stable and insulated within a box. They are a good option for shipping & packing materials for expensive commodities like electronics whose mishandling can lead to internal damage. The inserts tend to be thick, ensuring any damage to the box does not get to the contents within. Cardboard inserts can be used for less expensive and smaller lightweight items.
Bubble wrap offers a great cushioning effect that is ideal for protecting fragile items. It is made up of air pockets or bubbles that ably absorb shocks and vibrations, preventing the contents of the box from becoming damaged. It is one of the most lightweight packaging materials, meaning little if any added cost of shipping. There are several variations of bubble wrap including those that come with different sized “bubbles” and self-adhesive options.
Different kinds of paper can be crumpled up and stuffed around objects in a box. They can also be wrapped around the items. This helps to stabilize them and absorb any shocks during transport. If several items are being kept in the same box, this also helps to ensure they do not bang into each other causing breakage. You can use just about any paper with newspaper and brown paper often being chosen.
Traditionally made from polystyrene, these packaging materials are great for filling up awkward spaces around products that are being boxed. When filled in a box, they provide a soft barrier around the product that can absorb shocks, shaking, jostling, and other rough handling. They can be found in a variety of shapes and sizes. There are also recyclable and biodegradable varieties that are safe for the environment. They have also been made non-toxic due to the frequent occurrence of children eating them.
