Three Mistakes Buyers Make When Ordering Packaging Tape

We get a lot of calls that start with “the tape isn’t sticking” or “the tape is failing on the trucks.” Nine times out of ten, the tape wasn’t defective. The order was placed wrong to begin with. Here are the three mistakes we see most often, and how to avoid them.

Mistake 1: Cutting micron thickness to save on cost

Micron thickness is the one number buyers try to shave down first when a quote comes in higher than expected. It seems like a safe place to cut, since the tape “still seals the box.” But thickness is directly tied to tensile strength and how the tape holds up under load, vibration, and time.

A carton sealed with 35-40 micron tape might look fine on the day it leaves the warehouse. Three weeks later, sitting in a transit hub or getting reloaded twice, the seal starts lifting at the corners. By the time it reaches the customer, the flap is open and the tape looks “weak,” when actually it was just under-specced for the job.

Rough guide we work with on our own line:

• 35-40 micron: light cartons, short single-leg transit, low handling
• 45 micron: standard e-commerce and FMCG cartons, the most common pick
• 50-60 micron: heavier cartons, multi-city transit, more handling points
• 65 micron and above: export shipments, repeated handling, long storage before use

The cost difference between 40 and 50 micron on a jumbo roll is small compared to the cost of a damaged shipment, a return, or a customer complaint. If you’re unsure which band your product falls into, tell us the carton weight, the number of handling points, and the transit time, and we can recommend a micron range instead of guessing.

Mistake 2: Ignoring how the tape will be stored

Buyers spec the tape for the shipping conditions and forget about the storage conditions before it’s even used. This matters more in India than in most places, because warehouse temperatures in Delhi, Gujarat, or coastal cities can swing hard between seasons.

BOPP tape with a water-based acrylic adhesive performs well across a wide temperature range, but it still has limits. Rolls stored near a tin roof in summer, stacked directly under skylights, or kept in a non-ventilated container for weeks can see the adhesive soften or the roll edges deform. On the other end, tape stored in cold, damp conditions for pharma or cold-chain use needs to be tested for that specific range, not just assumed to work because it’s “the same tape we always use.”

A few practical points:

• Store rolls flat or upright as per the box instructions, not lying on their side in a crushed stack
• Keep tape away from direct heat sources and direct sunlight in the warehouse
• If you’re running cold-chain or cold storage packaging, tell your supplier upfront. Adhesive behaviour at low temperature is not the same as at room temperature, and it needs to be checked before a full order, not after
• Rotate stock. Tape sitting unused for a year in a hot storeroom is not the same tape it was on day one

None of this is complicated, but it’s the kind of thing that gets skipped when someone is focused only on getting the order placed and the boxes moving.

Mistake 3: Skipping the sample roll before placing a bulk order

This is the most common and most avoidable mistake. A buyer likes the price, likes the spec sheet, places a bulk order for a full truckload of jumbo rolls, and only finds out on the packing line that something’s off. Maybe the adhesion is weaker than expected on their specific carton board. Maybe the roll width doesn’t match their machine’s setup as well as the old supplier’s did. Maybe the print registration on custom tape isn’t lining up the way they pictured it.

All of this shows up in the first ten minutes of running a sample roll on your actual packing line, with your actual cartons, at your actual sealing speed. It does not show up on a spec sheet.

What a proper sample test should cover:

• Unwind and application on your machine, whether it’s hand-held dispensers or an automatic case sealer
• Adhesion on the specific board grade and finish of your cartons, not a generic test surface
• Behaviour at your typical sealing speed, since tape can behave differently at high line speed versus a slow manual seal
• A few days of shelf time before checking peel strength again, since some adhesives need time to reach full tack

We supply sample rolls before bulk orders for exactly this reason. It costs a small amount of time upfront and saves a much larger amount of time, money, and reputation if something doesn’t match the way you expected. If a supplier is reluctant to send a sample roll or pushes you straight to a full order, that’s worth noticing.

Getting the order right the first time

None of these three mistakes are about bad manufacturing. They’re about the ordering process itself, decisions made at the quotation stage before a single roll gets slit. Spec the micron for the actual handling conditions, not just the invoice cost. Account for how and where the tape will sit before it’s used. And always run a sample roll on your own line before committing to a bulk quantity.

If you want help working out the right micron and adhesive combination for your product, send us your carton weight, transit route, and storage conditions. We’ll suggest a spec and send a sample roll to test before you place a full order.
