5 Packaging & Label Myths from a Procurement Pro: Duct Tape, Super Glue, Foam Board & More

Let's Talk About the Stuff You Actually Use

I've been a procurement manager for a mid-sized consumer goods company for over six years now. We handle a lot of custom packaging—labels, boxes, printed tape for our retail lines. You'd be surprised how much of my day gets eaten up by people asking if Gorilla Tape is 'basically' duct tape. Or if they can use a $4 tube of super glue to seal a critical shipment.

Here are five of the most common questions I get, answered from a budget-keeper's perspective. I don't have hard data on industry-wide misuse rates, but based on tracking roughly $180,000 in annual packaging spending across those six years, my sense is that these myths cost businesses about 8–12% of their budget in rework and emergency purchases. Let's fix that.

1. Is Gorilla Tape the Same as Duct Tape?

Short answer: No. Not even close.

This was true about 15 years ago when 'duct tape' was just one thing. Today, it's a category. Gorilla Tape is a specific, high-strength variant within that category. The misconception comes from an era when duct tape was a simple cloth-backed, rubber-adhesive product.

Here's the core difference: Gorilla Tape uses a thicker, double-layer adhesive. It's not 'slightly better' duct tape. It's a completely different beast. For a quick repair on a box or a temporary hold? Sure, it works. But if you're using it on a production run of shipping cartons, you're overpaying by about 30–40% compared to a standard, high-performance shipping tape from a packaging supplier. That 'better hold' is wasted on a standard carton.

My experience is based on about 200 mid-range orders for custom printed tape. If you're working with ultra-heavy or industrial goods, your needs are different. But for 95% of standard B2B shipping, a specialized shipping tape is the correct tool. (Source: Internal vendor quote comparisons, Q3 2024).

2. Can I Use a 'Gorilla Gel Super Glue' for General Sealing?

I see this one a lot. Someone grabs a tube of Gorilla Super Glue from the supply closet because 'it's strong.' And it is. It's incredibly strong.

But the question isn't if it can hold. It's if it should. For a permanent, non-structural seal on an envelope or a small display, it's a disaster. It's thick, slow-drying (for a CA glue), and creates a brittle joint. If the envelope needs to flex, it will crack. We had a $1,200 redo when someone used this to seal a custom booklet, and the spine shattered in shipping.

A better approach? For most packaging seals—envelopes, boxes—a hot-melt glue, a standard adhesive tape, or a specific pressure-sensitive label is cheaper, faster, and more flexible. The 'super glue' is a specialist tool for non-porous surfaces and quick fixes, not for assembly-line packaging.

3. What About 'Gorilla Sealer'? Is That Just Caulk?

No. This one is a bit more nuanced. A 'sealer' in the packaging context is usually a water-resistant coating or a tape. But most people asking this question are actually looking for a caulk or a spray sealant for a physical gap.

If you are trying to seal a foam board display or a box against moisture, using a liquid sealer is often a bad idea. It's messy. The solvents can attack the foam or the paper covering. I've seen people ruin entire batches of custom foam board displays—the kind used in retail POP—by trying to waterproof them with a sealer.

A better solution: If you need a waterproof box, buy a box made with a waterproof coating, like a poly-lined or wax-coated board. Or, for a temporary seal, a waterproof tape. Don't reinvent the wheel with a liquid sealer. The vendor that says 'this isn't our strength, here's a coated box supplier' earns my trust for everything else.

4. Is a Standard 'Company Envelope' Always the Best Choice?

Not always. The 'company envelope' (a #10 or similar) is a commodity. It's cheap and it works for a letter. But in my experience, about 40% of our 'envelope' shipments were actually for materials that needed more protection.

Here's the reality: A standard paper envelope offers almost no protection. If you're sending a small custom sticker, a patch, or a small label sample, a paper envelope will often result in a damaged package or a lost item. The cost of a single reprint ($2–$5) plus shipping easily exceeds the savings from not using a padded mailer ($0.30–$0.50).

Consider a 'tough envelope' or a poly mailer. It's a tiny premium on a per-unit basis, but it eliminates the 'my sample arrived creased' complaint. That saves time, trust, and money. (Price reference: Paper envelopes are ~$0.10 each; poly mailers are ~$0.35, based on major online printer quotes, January 2025).

5. Can I Use a 'Round Foam Board' for Everything?

No. Round foam board (like Gatorfoam or a similar rigid foam) is a wonderful material for displays and signs. It's lightweight, rigid, and easy to cut. But it's a specialist material.

The myth is that because it's 'strong,' it can replace a box. It cannot. A box is a structural container designed for stacking and impact. A round foam board is a flat substrate. If you use a circle of foam board as a base for a display, that works. If you try to use it as a lid or a shipping container, it will fail under pressure. The foam is compressible.

I've only worked with domestic vendors for this material, so I can't speak to international sourcing. But here's a rule of thumb I use: If you need to carry it, use a box. If you need to read it, use foam board. They are not interchangeable, and forcing one to do the other's job is a recipe for a $450 damage claim.

One Last Tip: How to Remove Super Glue from a Package

Since that's a popular search query: acetone (nail polish remover) works on non-porous surfaces. On a label or a printed box, it will ruin the print. You can't 'remove' it from paper. The print will lift. The only solution is prevention. If you are applying a glue-based seal, do it on the plastic closure, not on the paper.

In Q2 2024, we had a vendor switch our order to a glue-based seal without telling us. It was a nightmare. Our cost tracker showed a 15% increase in 'rejected' inventory from that one mistake. We implemented a 'glue type must be approved in writing' policy after that. Lesson learned the hard way.
