Custom Tray Inserts
Our custom cardboard tray inserts hold each item securely in place, so your inventory doesn’t shift during shipping. Rather than using loose-fill peanuts or plastic air pillows, you can rely on engineered paperboard to keep everything steady, whether it’s heavy glass jars or delicate electronics. This not only protects your products but also gives your customers a high-quality unboxing experience that highlights your brand’s commitment to quality.

The Sensory Edge of Engineered Paperboard Tray Insert
When you place a product into a well-designed cardboard insert, you notice a secure 'friction-lock' feel. We’ve tested these inserts in busy fulfillment centers, and the results are clear: unlike plastic trays that can crack and form sharp edges, cardboard is both strong and flexible. The fluting in the cardboard acts as a natural shock absorber, spreading out the force if the box is dropped. There’s no rattling, no sliding, and no messy plastic film—just a neat, organized setup that looks great and works well.
Eliminating the "Rattle" with Custom Die-Cutting
We use precise steel-rule dies to cut cavities that match your product’s shape exactly. Through our hands-on design process, we’ve learned that even small changes in score depth can affect how the tray fits in the box. Our inserts are made to fit snugly against the box walls, creating a suspension effect. This way, even if the outer carton is damaged, the inner tray stays intact and protects your valuables.
Sustainable Brand Authority
Today’s consumers often see plastic-heavy packaging as cheap and wasteful. By choosing 100% recyclable paperboard, you offer a natural feel that appeals to eco-conscious buyers. The matte cardboard surface is also great for branding, letting you print instructions or brand values right on the tray and turning packaging into a marketing tool.
Structuring a Multi-Layer Packaging Solution
A cardboard tray forms the base of your package, but it works even better when combined with other organizing layers. For kits with multiple parts, we often suggest adding cell dividers to keep small hardware separate from the main item. This helps prevent metal or plastic pieces from scratching your main product.
For luxury products, you can add foam inserts to the cardboard for extra protection and a soft-touch feel. To help your customers find important information right away, our trays can include a slot for instruction sheets or glossy warranty cards, putting your documents front and center. If you want to go fully plastic-free, using recycled paperboard inserts for your packaging creates a clean, sustainable look.
Frequently Asked Questions About Cardboard Tray Inserts
Picking the right fluting size and paper weight helps you balance shipping costs with how much protection your products need. Here, we answer common questions about the strength and design of paper-based packaging.
Read our Custom Packaging Support & Ordering FAQs →Are cardboard trays strong enough for heavy glass or liquids?
Yes. With double-wall construction and reinforced bridge-folds, our trays can hold a lot of weight. Cardboard is actually stronger than many thin plastics when stacked, so it works well for heavy retail kits and keeps the bottom tray from collapsing.
How do I know the tray will fit my specific box?
We make your tray about 1.5mm smaller than the inside of your main box. This small gap makes assembly fast and easy, but the tray still fits tightly and won’t shift during shipping.
Can I get a sample before ordering 1,000 units?
Absolutely. We offer CAD Samples or White Samples, which are unprinted prototypes made to your exact size. We suggest doing a shake test with your product in the sample to make sure the fit is right before we start full production.
Is it better to use Kraft or White cardboard?
Natural Kraft is tougher and better at hiding scuffs, so it’s often used for industrial or organic brands. White cardboard looks cleaner and more clinical, which is popular for medical, cosmetic, and luxury tech products.
Do these trays arrive assembled?
To help you save on shipping and storage, most of our tray inserts arrive flat. They are pre-scored and made for quick assembly, so your team can set them up in one motion during packing.
Can I print my social media handles on the tray?
Yes. Cardboard is great for high-quality printing, unlike plastic. We can print QR codes, thank you messages, or your social media handles right on the tray to help boost digital engagement.
