If you've ever opened a shipment to find something cracked, scratched, or rattling around inside a box with zero cushioning, you already know the problem. Generic padding doesn't cut it. And honestly? That's exactly why custom foam inserts for boxes from Althor exist — precision-cut, made-to-measure protection that actually does its job.

We're based in Windsor Locks, CT, and we've been doing this for over 50 years. That's not a flex — it's just context for why we take foam seriously.

So, What Are Foam Inserts and Why Do They Matter?

Simple answer: foam inserts are custom-shaped cushioning pieces placed inside a box to hold your product securely during shipping, storage, or display. But the "custom" part is where things get interesting.

Off-the-shelf bubble wrap or crumpled paper? Sure, it works sometimes. But when you're shipping electronics, medical devices, tools, jewelry, or any product where presentation and safety both matter — you want foam that's cut to the exact shape of what's inside. No shifting. No impact. No returns.

From what I've seen across industries, the biggest mistake shippers make is treating packaging as an afterthought. It's not. It's part of your product experience.

What Makes Althor's Foam Box Inserts Different

Look, there are foam insert suppliers out there. A lot of them. But here's the thing — most cater to massive order volumes, leaving small and mid-size businesses scrambling for options that actually fit their product and their budget.

At Althor, we work with businesses of all sizes across the USA. Our foam box inserts for shipping and packaging are fabricated from high-quality materials including polyethylene (PE), polyurethane (PU), and expanded polystyrene (EPS) — each suited for different protection needs.

Custom branding options — because unboxing matters to your customers

Types of Packaging Foam Inserts We Offer

We get a lot of questions about what type of foam works best. Honestly, it depends on your product — but here's a quick breakdown:

Polyethylene (PE) foam — great for heavier items needing firm, closed-cell support; resists moisture

Polyurethane (PU) foam — softer, open-cell structure; ideal for delicate or irregularly shaped products

EPS (Styrofoam-style) inserts — lightweight, cost-effective; common in consumer electronics packaging

Sponge inserts for boxes — open-cell, flexible; perfect for tools, display cases, and presentation boxes

Each material has its sweet spot. If you're not sure which fits your product best, our team will walk you through it — no sales pressure, just practical advice.

FAQs About Custom Foam Inserts

What's the difference between foam inserts and sponge inserts for boxes?

Good question — they're often used interchangeably, but technically, sponge inserts are open-cell foam (softer, more compressible), while foam inserts can be either open or closed-cell depending on the material. For display cases and tool organization, sponge-style inserts are popular. For heavy-duty shipping protection, closed-cell PE or EPS tends to hold up better.

Can I order custom foam inserts in small quantities?

Yes. This is actually one of the more common pain points we hear from small businesses — most foam inserts suppliers have high MOQs that just don't work for smaller operations. At Althor, we're flexible. Reach out and tell us what you need.

How long does it take to get custom foam packaging inserts made?

It varies by complexity and order size, but because we manufacture locally in Windsor Locks, CT, our turnaround is generally faster than overseas suppliers. Rush orders? We can usually accommodate.

Are your foam inserts suitable for shipping fragile or high-value products?

Absolutely. That's kind of the whole point. Our foam is selected and cut specifically to absorb impact during transit — so whether you're shipping glass, electronics, or precision instruments, the product arrives the way it left.

Do you offer foam inserts for branded packaging?

Yes. We can work with custom colors, cut logos, or create tiered foam layers that create a premium unboxing experience — the kind that people photograph and post about.

Bottom Line

You're not just buying foam. You're buying fewer returns, fewer complaints, and a better first impression every time someone opens a box with your product inside. Althor has been making that happen for over five decades — and if you're looking for foam inserts suppliers in the USA who actually pick up the phone and get it right, we're worth a conversation.

You've got a product that needs protecting — and you've probably already learned the hard way that bubble wrap and crumpled paper only go so far. Foam inserts for cases and boxes exist for exactly this reason. And when it's done right, the insert does more than protect the product. It communicates quality. It says: we thought about this.

At Althor, we supply packaging foam inserts for businesses across the USA — from small-batch product sellers to industrial manufacturers who need thousands of units shipped without a scratch.

The Foam Types — and What Each One Actually Does

Not all foam is the same. Honestly, this is where a lot of buyers go wrong — they order generic foam and wonder why it doesn't hold up. Here's a plain-language breakdown:

Polyurethane (PU) foam — The most common, open-cell structure, great for light cushioning; used in electronics, medical kits, and display boxes

Polyethylene (PE) foam — Closed-cell, firmer, water-resistant; ideal for tools, instruments, and anything exposed to moisture

Expanded Polystyrene (EPS / Styrofoam inserts) — The rigid white stuff; excellent for shipping fragile or temperature-sensitive items

Pick-and-pull grid foam — Pre-scored foam blocks where you pull out cubes to create a custom fit without any cutting tools

Convoluted (egg crate) foam — Textured surface for even load distribution; good for multi-item packaging

Each material has a specific use case. If you want a full breakdown of which foam type fits which industry, this guide to custom foam packaging inserts for USA buyers covers the materials, types, and applications in detail — worth reading before you spec your order.

Who's Ordering Foam Packaging Inserts From Us?

More industries than you'd expect. From what we see across our USA customer base:

Electronics manufacturers — Boards, instruments, and testing equipment that can't arrive with a single ding

Medical device companies — Surgical kits, diagnostic tools, specimen transport — where insert fit is often a compliance issue

Defense and firearms — Hard-shell cases with precision-cut foam inserts for weapons and accessories

Tool and equipment suppliers — Presentation-quality cases with foam-cut layouts for field kits

Cosmetics and retail brands — Unboxing experience matters; foam liners in gift boxes make a statement

Industrial shippers — Custom sponge inserts for boxes that protect machined parts during transit

Custom vs. Stock Foam Inserts — Which Do You Need?

This is sort of the first question you should ask yourself. Stock foam inserts are faster and cheaper upfront. Custom foam inserts are better for anything with an irregular shape, high-value contents, or a branding requirement.

But here's the thing — custom isn't always as expensive or slow as people assume. Die-cut tooling costs have come down significantly, and CNC-cut foam doesn't require tooling at all. If you're ordering 50 units or more, custom usually pays for itself within one or two production runs. Less product damage, better unboxing presentation, fewer returns.

Speccing Your Foam Insert Order — What to Know First

Before you request a quote for foam inserts for cases or boxes, have these details ready:

Box or case dimensions — Interior length × width × depth (not exterior)

Product dimensions and weight — Especially if it's irregular or multi-piece

Foam type preference — PE, PU, EPS, or pick-and-pull? (Or let us recommend)

Quantity — Prototype run vs. production volume changes the cutting method

Cutting method preference — Die-cut, CNC, or waterjet

Color — Standard charcoal/black, white, or custom color?

Any compliance needs — Anti-static, fire-retardant, or FDA-contact requirements

Well, actually — if you're not sure about the foam type, just tell us what you're shipping and the environment it's going into. We'll work backward from there.

FAQs

What's the difference between foam inserts for cases and foam packaging inserts?

Mostly context. Foam inserts for cases typically refers to precision-cut inserts for hard-shell cases — think equipment cases, gun cases, or presentation cases. Foam packaging inserts is the broader term covering any foam liner or insert used inside a shipping or retail box to protect contents during transit.

Are styrofoam inserts the same as EPS foam inserts?

Sort of. "Styrofoam" is technically a Dow Chemical brand name, but it's become shorthand for expanded polystyrene (EPS) foam in general. EPS/styrofoam inserts are rigid, lightweight, and excellent for temperature-sensitive or heavy fragile items. They differ from soft polyurethane foam, which is flexible and better for surface protection.

Can I get custom sponge inserts for boxes without a large minimum order?

Yes. CNC and waterjet cutting don't require expensive die tooling, so small-run custom sponge inserts for boxes are genuinely cost-effective — even for prototype quantities. For larger volumes, die-cutting brings the per-unit cost down further.

What foam is best for electronic equipment packaging?

Polyethylene (PE) foam is the go-to for electronics — it's closed-cell (won't absorb moisture), offers consistent cushioning, and is available in anti-static formulations to protect sensitive components. Polyurethane is softer and fine for lighter electronics.

How long does it take to get custom foam packaging inserts?

Turnaround depends on cutting method and quantity. CNC-cut inserts often ship within a few business days of approved dimensions. Die-cut production requires tooling lead time but is faster for large runs. Contact Althor directly for a current lead time on your specific requirement.
