Protecting products against the shocks, loss and damage received during transport is a big part of the value proposition of specifying a reusable custom case. ## Right Case, Wrong Foam Insert Instead of issues with the case, the problem could be your foam insert. If you didn’t consult custom packaging engineers, like the experts at M-Line, you might end up with a suboptimal foam insert solution in your cases – limiting the effectiveness of your product packaging. Custom cases are selected when products demand rigid, reusable packaging. Cases serve as a convenient way to transport and store products safely. But the workhorse of this packaging solution are the custom case foam inserts. The combination of the durable outer case and the cradling protection of the internal foam gives these cases their superior performance capabilities. ## Choosing the Best Foam Solution Customers have a multitude of foam choices that can make the difference between a safely delivered product and a broken one. Some of these include: - **Polyethylene:** This strong, resilient, closed-cell foam is an ideal shock absorber for products while serving as an excellent vibration dampener. - **Crosslinked polyethylene:** This very fine, closed-cell foam has a smooth feel. It’s used extensively in automotive applications where Class A surface protection is required. High tear resistance and excellent foam memory make this the ideal choice when repeat uses are required. - **Polyurethane:** A soft, sponge-like, open-cell foam, it can be used in many different applications. The engineers and designers at M-Line recommend the best foam type for your specific product and that product’s expected use and transport environment. Our customers’ custom case foam inserts are designed to keep products securely in place to prevent shifting and damage. ## M-Line's Custom Case Foam Experts With nearly 40 years of packaging expertise and experience, M-Line offers solutions to all your packaging challenges.
