How do you choose the perfect foam?

We recommend selecting your packaging foam based on three key criteria: the fragility, weight, and dimensions of your items.

For delicate items, choose a foam with high shock absorption. Heavier products, on the other hand, require a denser foam that provides sturdy support. The goal is to match the type of foam to your specific packaging needs.

Here are the key factors to consider when choosing the perfect foam:

  • Fragility: Assess how vulnerable your product is. Highly fragile items, such as electronic devices, require foams with excellent shock absorption, such as polyethylene or polyurethane.
  • Weight and size: Heavy and bulky items require dense foams like polyethylene to ensure stability. Lightweight and small products benefit more from cushioning with flexible polyurethane foams.
  • Budget: Compare the costs of different options. Expanded polystyrene (EPS) is cost-effective for less delicate items, while cross-linked polyethylene (XLPE) offers superior protection at a higher price.
  • Sustainability: Choose eco-friendly, biodegradable, or recycled foams to reduce environmental impact. This option is particularly relevant for environmentally conscious brands.
