Custom Packaging: Factors for Selecting Foam Case Inserts

When choosing custom packaging solutions for your products, you should consider foam case inserts. These are advantageous products because the design and material provides optimal protection for delicate products. In simple terms, foam materials will be cut into custom shapes that match the shape of your commodities. The good fit will limit accidental slipping of the good after packaging and the foam will provide shock absorption and thermal insulation. If you are thinking about acquiring this type of packaging, consider these factors for an ideal foam case insert.

Base Foam Material

The base foam is the material which will be cut to create shapes that can efficiently cradle the commodities. Therefore, it is important to select a material that is durable, can support the weight of the goods and provide all-round protection. Polyethylene foam is appropriate for most packaging applications because the material is lightweight and durable. The surface of this material is soft, so this is a suitable choice for products that are sensitive to abrasion.

Additionally, the foam has closed cells which make it impervious to moisture and subsequent mildew growth. Cross-linked polyethylene is a variant with a more resilient structure for prolonged lifespans, and this is available in assorted attractive colours. If you are packaging delicate goods, consider selecting the less rigid, open-cell polyurethane. This has excellent cushioning properties, so it will protect fragile, lightweight objects.

Lid Foam Design

If the lid fabricated for the case inserts is not perfect, the integrity of the packaging will be compromised. Basically, this component should secure the products in place and protect the exposed parts of the commodities. There are two common designs used in lid foam manufacture: convoluted and flat foam. The convoluted design is formed in an egg-crate style that cups the upper part of the products. It is a good choice for your items if they will protrude from the top of the base lid. On the other hand, the flat design is a favourable when the products are flush with the surface of the base.

Cutting Technique Factors

There are different techniques that are used to cut the foam into the desired designs. You should discuss the available options with your fabricator so that you can identify the most appropriate for your business' long-term packaging solution. Ideally, you should compare the cost of each method per case insert unit. Additionally, the techniques can vary significantly in terms of design precision and speed of production. Therefore, evaluate these aspects with respect to your immediate packaging requirements before selection.
