Carton Sealing Tape: Adhesive, Mil and Case Comparison
T901516PK and T901131 are both clear carton-sealing tapes listed at 2 inches wide and 55 yards long per roll. The differences to compare are adhesive description, listed mil thickness, and case quantity. Those differences should remain visible when choosing a tape or reviewing a proposed substitute.
T901516PK is listed as natural rubber tape at 2.2 mil in a six-roll case. T901131 is listed as acrylic tape at 3.1 mil in a 36-roll case. Neither the thicker listing nor the larger case establishes which product performs better for your carton and application process.
Compare the exact specifications
| Product | Adhesive description | Width | Length per roll | Listed thickness | Rolls per case |
|---|---|---|---|---|---|
| T901516PK | Natural rubber | 2 inches | 55 yards | 2.2 mil | 6 |
| T901131 | Acrylic | 2 inches | 55 yards | 3.1 mil | 36 |
The matching width and roll length make the quantity comparison straightforward. The adhesive and listed thickness still need to stay attached to the SKU. An order described only as “clear 2-inch tape” omits the fields that distinguish these products.
Read the mil number as a specification
A mil is one thousandth of an inch. The listed 2.2 mil converts to 0.0022 inch or 55.88 micrometres. The listed 3.1 mil converts to 0.0031 inch or 78.74 micrometres. The numerical difference is 0.9 mil, equivalent to 22.86 micrometres.
Use these conversions to reconcile units on a purchasing specification. Do not turn the difference into an adhesion, strength, temperature, or service-life claim. If your specification distinguishes backing thickness from total tape thickness, obtain that exact field for the selected product instead of assuming the listing's mil number answers both.
Keep adhesive choice separate from case size
Natural rubber and acrylic are the adhesive descriptions for these two listings. Select against the requirements of your actual carton, closure method, and application equipment. Document the relevant supplier information and evaluate the selected tape in that process before making it the standard reorder.
When reviewing a substitution, compare the full set of fields: SKU, adhesive description, width, roll length, listed thickness, and rolls per case. If one field changes, make the change explicit. A matching 2-inch width does not resolve missing core or roll-diameter information for the dispenser.
Worked order: 24 rolls of the chosen tape
Assume a hypothetical purchasing requirement of 24 rolls after the tape specification has been chosen. T901516PK requires four cases because 24 ÷ 6 = 4. That supplies 24 rolls and 1,320 yards.
T901131 requires one whole 36-roll case, supplying 1,980 yards and leaving 12 rolls beyond the stated requirement. The extra quantity is a purchasing consequence of that case size. It is not evidence that one product is cheaper, more efficient, or a suitable substitute for the other.
For an equal-length quotation comparison, divide each current case amount by its roll count to obtain a per-roll amount. Because these rolls are both 55 yards long, divide that result by 55 for a per-yard amount. Keep the case total and the unused-roll quantity visible alongside the unit figure.
Specify the reorder completely
A clear line item reads “T901516PK, 2-inch × 55-yard clear natural rubber tape, listed 2.2 mil, four six-roll cases” or the corresponding full specification for T901131. This identifies both the material choice and the order unit without relying on a generic tape name.
Use the tape roll length guide to convert measured consumption into cases, and the dispenser guide to review equipment requirements. Open the exact product above to order, or request a quote with the SKU, specification, and case quantity.
