I manage packaging procurement for a mid-sized food company. Last year I almost cost my company over $4,000 because I trusted a unit price.
In Q2 2024, we needed 100,000 food-grade PET bottles for a new single-serve product. One supplier quoted $0.11 per bottle. The supplier we'd used before quoted $0.16, all-in. My first thought? The incumbent was trying to make up lost margins. My second thought was, "let's go with the cheap one and save $5,000."
Good thing I didn't. The $5,000 in "savings" would have disappeared fast. The cheap quote didn't include shipping ($0.014 per unit), mold amortization ($2,200), the color-matched resin premium ($0.009 per unit), or line trial fees ($1,800). By the time I added everything, that supplier was actually $0.173 per bottle—more expensive than the incumbent's all-in number.
This is the problem nobody wants to talk about: packaging pricing is rarely what it looks like.
The problem you think you have: packaging costs too much
In procurement, the surface problem is simple. Unit costs are up. PET resin prices fluctuate. Shipping surcharges appear. You search for "cheap plastic packaging" and get a range of quotes that seem hard to compare.
So you do what I did: compare the unit price on the column. It feels objective. It feels smart.
But it's not the real problem.
The deeper issue: the quote isn't the cost
The deeper issue is that no two packaging quotes include the same things. "All-in" gets thrown around a lot, but I've learned to ask one question first: "What's not included?"
Here's what I've found hiding in quotes for rigid packaging over the past three years:
- Tooling and mold fees. Sometimes amortized over the first order, sometimes charged separately, sometimes "free" until you need a second cavity.
- Resin grade and color. Food-grade PET and polypropylene have different price levels. A custom color with special effects—even a subtle sparkle like resin glitter—can add a lot.
- Shipping and logistics. Unit price might be FOB factory, not delivered. I've seen freight costs swing 20% or more depending on lane and time.
- Quality testing and documentation. If you need a certificate of analysis, FDA/EFSA documentation, or line trial reports, those often show up as line items.
- Artwork, plates, and cylinders. For decorated packaging, prepress charges can be significant.
- Minimum order quantities and split deliveries. A lower unit price with a huge MOQ can force you to tie up cash in inventory.
- Rush fees and change fees. If your packaging uses UV-cured inks, the curing line speed and setup time affect cost even before you start searching for the best uv light for curing resin.
Here's a sentence I never thought I'd write: don't pay extra for a logo. When someone says "these are Amcor products" and points to the Amcor logo, that's a marker of accountability, not a technical spec. What matters is whether the supplier will put its commitments in writing—lead times, performance, return policy.
What ignoring this actually costs
Let me give you three numbers from my own records.
$450. That's what a "free setup" offer cost us in 2023. The setup was free. The artwork revision was not. The color match was not. The extra sample run was not. The final invoice was $450 higher than the "free" quote.
$1,200. That's the redo cost when a cheaper supplier's packaging failed a drop test. We skipped the full quality review because "it's basically the same as last time." It wasn't. The product was the same, but the resin source was different, and the bottle cracked at the neck.
$8,400. That's the annual saving when we switched packaging suppliers after doing a proper total cost analysis. The new supplier's per-unit price was 3% higher. But their lead times were consistent, their quality problems were almost zero, and their quote included shipping. We saved 17% of our packaging budget.
That third number is the one that quietly frustrates me. I had been "saving" money for years by picking lower quotes, and each time I was actually leaving money on the table.
The problem with "cheap" isn't the price—it's the uncertainty
To be fair, not every low quote is a trap. Some suppliers are genuinely more efficient. And not every high quote is honest—I've seen high-priced suppliers with poor delivery performance too.
But there's a pattern. When a supplier lists all the fees upfront, the quote looks higher at first. When the fees are hidden, the quote looks lower. The hidden fees come back later, usually with interest.
I've never fully understood why the packaging industry doesn't standardize this. My best guess is that buyers compare unit prices, so suppliers learn to make unit prices look good.
It's tempting to think you can just compare unit prices. But identical specs from different suppliers can result in wildly different outcomes.
Maybe that's the whole game.
What I ask now (and what you should ask too)
Before I evaluate any supplier—including Amcor products or a smaller domestic molder—I use a simple checklist:
- Get the full breakdown. Unit price, tooling, shipping, packaging, duties, samples, testing.
- Ask "what's not included" out loud. Yes, out loud. It changes the conversation.
- Define total cost of ownership. Include the cost of a late shipment, a quality failure, and a line shutdown. Those don't appear on the invoice, but they're real.
- Check the guarantee. The value of guaranteed turnaround isn't the speed—it's the certainty. For event packaging or seasonal launches, a "pretty sure" supplier is expensive.
- Put the "cheap" quote into a spreadsheet. I built a simple cost calculator after getting burned on hidden fees twice. It's not pretty, but it works.
If you're doing a PET search for suppliers, remember that search results are not quality judgments. A supplier ranking first for "PET bottles" may be great, or it may just have good SEO. The same goes for "Amcor products" if you land on a partner page: verify the product spec, the resin grade, and the written lead time.
One more thing about UV-cured materials. If you're searching for the "best uv light for curing resin" because you're making a product with UV-cured coatings, that's a process question. For packaging, the related question is whether the converter's UV curing equipment can handle your design without slowing down the line. That affects cost and delivery—and it's rarely in the quote.
The bottom line
The cheapest quote is not the cheapest cost. That sounds obvious, but I had to get burned twice before I believed it.
Now my procurement policy requires at least three quotes, a TCO spreadsheet, and a written answer to "what's not included." It takes more time. It feels bureaucratic. But it saved us $8,400 in one year—and it made my job a lot less stressful.
To be fair about my sample: my experience is based on about 200 mid-range packaging orders over six years. If you're sourcing ultra-budget disposables or luxury custom rigid boxes, your numbers will look different. But the questions are the same.
I'm not saying every low quote is a scam. I'm saying the price you see is not the price you pay. Do the math. Ask the question. And when a supplier gives you a clean, transparent quote—even if the total looks higher at first—that's usually a sign they're not hiding anything.
Prices and quotes referenced are from my own orders in 2023-2024, not a market benchmark. Verify current rates with your suppliers.
And honestly? That's worth more than a logo on a quote.
