I Bought the Wrong Candy Packaging Machine Twice: A 7-Point Checklist

If you've ever had a packaging line go down the day before a major holiday order, you know the specific kind of panic I'm talking about.

I'm a production manager handling packaging equipment procurement for a mid-sized confectionery manufacturer. I've been doing this for about six years now. In that time, I've personally made (and documented) three significant equipment purchasing mistakes, totaling roughly $14,000 in wasted budget and countless lost production hours. Now I maintain our team's checklist to prevent others from repeating my errors.

Here's the thing about candy packaging machines: they look simple. A conveyor belt, some film, some heat. How complicated can it be? I learned the hard way that packaging flow pack machines are surprisingly nuanced. Especially if you're dealing with sticky products, irregular shapes, or tight deadlines.

Below is the 7-point checklist we use before even talking to a supplier about a china pillow type packing machine or any food packing machine. Run through this before you sign anything.

Who This Checklist Is For

You're a production manager, plant supervisor, or owner of a confectionery business. You're looking at packing machines—specifically flow wrappers—for chocolate bars, hard candies, lollipops, or gummies. Your order volumes are medium-to-high (let's say 50+ packs per minute), and you need reliability first and foremost.

There are 7 steps below. Step 4 is the one most people overlook. I skipped it on my first purchase. Cost me around $3,200 in wasted product and a very tense call with our largest retailer.

Step 1: Product Geometry Check (Don't Skip This)

This sounds obvious, honestly. But you'd be surprised how many people buy a packaging machine based on a product's weight, not its dimensions.

I once ordered a flow wrapper packaging machine for a new line of toffee bars. The bars were 55g each, which fit within the spec sheet. But the shape was slightly tapered—wider at the base than the top. The machine kept misfolding the ends. We spent two weeks adjusting the forming box before we admitted it was the wrong machine for the product.

What to do:
Take physical samples of your product to the supplier. Run 50 or 100 packs on their demo machine. Don't just rely on spec sheets. Film thickness, surface texture, and product rigidity all matter.

Check point: Ask the supplier: "Have you run a product with this exact geometry before?" If they hesitate, that's a red flag.

Step 2: Film Compatibility Test

Different wrapping films have different sealing temperatures, shrink rates, and slip characteristics. A packing machine that works perfectly with one film might jam constantly with another.

We switched film suppliers once to save $0.02 per meter. The machine's heat sealing rollers couldn't handle the new film's higher melting point. Packs weren't sealing properly. Product was leaking caramel. It was a mess.

What to do:
Send your preferred film (or several film options) to the machine supplier. Ask them to run a seal strength test at full production speed. Industry standard seal strength for confectionery flow packs is around 8–12 N/25mm, but check your own requirements.

Check point: Request a video of the machine running at your target speed (e.g., 100 ppm) with your film and your product.

Step 3: Speed vs. Reliability Trade-off

Here's where the time certainty argument comes in. Every supplier will quote a maximum speed. Usually something like "up to 150 packs per minute."

Here's what they won't tell you: running at 150 ppm means more jams, more adjustments, and more maintenance. The sweet spot is usually 60–80% of the rated max.

I learned this when we needed to rush a 50,000-piece order for a holiday promotion. The machine supplier promised 120 ppm. We accepted the quote, got it installed, and discovered that at 120 ppm, the machine jammed every 15 minutes. We had to run it at 75 ppm to get reliable operation. We missed the deadline anyway. The rush delivery costs to the retailer ate up any savings we thought we'd made on the machine price.

What to do:
Ask the supplier: "At what speed can you guarantee < 1 jam per shift?" That's your real production speed.

Step 4: Changeover Time (the Hidden Killer)

This is the step I originally skipped. It cost me dearly.

Most people focus on runtime speed. But if you're producing multiple products—different sizes, different shapes—changeover time crushes your overall efficiency. Our first china pillow type packing machine had a 45-minute changeover time between product sizes. We were losing 3 hours of production time per shift just swapping settings and forming boxes.

What to do:
Time the changeover yourself. Watch the supplier do it. Ask for a video. The difference between a 10-minute changeover and a 45-minute one is massive—especially during peak season.

Check point: If your production run is 2 hours and changeover is 45 minutes, your efficiency is terrible. Aim for changeover < 15 minutes.

Step 5: Spare Parts Availability (Don't Assume)

When the machine breaks—and it will, eventually—how fast can you get parts?

Our second machine was from a reputable manufacturer. But the supplier's local stock of sealing belts was zero. Every part had to come from overseas. That meant 2–3 weeks of downtime every time something wore out. We ended up buying a second machine just to cannibalize for parts. Dumb way to spend money.

What to do:
Ask for a list of the 10 most commonly replaced parts. Ask for current stock levels. Get a written commitment on shipping times for critical spares. Budget for a basic spare parts kit from day one.

Step 6: Check the Service Contract Terms

Service contracts are basically insurance. And in my experience, they're worth paying for—especially in the first year.

I'm not a mechanical engineer, so I can't speak to the finer points of gearbox maintenance. What I can tell you from a production manager's perspective is that a service contract with a 24-hour response time is worth paying $300–500 extra per year. One preventable breakdown during a major order wipes out that cost immediately.

What to do:
Compare the cost of the service contract vs. the cost of a single day of lost production. Which is larger? That's your answer.

Step 7: Power and Air Requirements

This one sounds boring, I know. But it's the most common "gotcha" I've seen in our industry.

We installed a food packing machine that required 80 psi compressed air at 15 CFM. Our facility only had 60 psi lines running at 10 CFM. We had to upgrade our compressor system. That cost about $2,800—totally unplanned. The machine's spec sheet listed the air requirements in small font on page 14 of the manual. Page 14!

What to do:
Confirm electrical (voltage, phase, amperage) and compressed air (pressure, flow rate) requirements before the quote is finalized. Send your facility specs to the supplier. Ask them to confirm compatibility in writing.

Common Mistakes & Warnings

Here are a few things I'd add based on my experience and what I've seen in the industry:

• Don't trust "plug-and-play" claims. Every machine needs tuning. Budget for 2-3 days of onsite commissioning and training.
• Film tension variation is a notorious problem on flow wrappers. Ask if the machine has automatic tension control—and test it.
• Industry seal strength standard for confectionery packs is typically 8–12 N/25mm seal width. If your supplier can't confirm their machine meets this, push harder.
• Rush shipping on a replacement part can cost 50–100% over standard. We paid $400 for overnight delivery on a sealing roller that should have cost $150. Plan ahead.

I wish I had tracked our machine downtime more carefully from the start. What I can say anecdotally is that the checklist above would have saved us roughly $8,000 in the first year alone. That's not including the stress and the late-night calls with angry sales managers.

Take it from someone who's made the mistakes: run through these 7 steps before you commit to any packing machine. It's boring work. But it beats explaining to your CEO why a $6,500 candy packaging machine is sitting idle while an order ships late.
