Export Packaging Specification for Tape Rolls: Every Field That Decides the Pack

Technical guidesPublished 07 November 2026Updated 07 November 2026

A roll of tape reaches a receiving dock with six properties fixed before it leaves Shenzhen: the core inside it, the direction it unwinds, which face of the web is outwards, how it is separated from its neighbours, how many share a carton, and what the carton label resolves to. An export packaging specification for tape rolls names all six, and each constrains the next.

What the document is, and what it is not

It is not the phrase "export packing" on a purchase order. It is a short, revision-numbered document stating the roll build being packed, the protection on each roll, the carton and its contents, the markings, the unit load if there is one, and the evidence that the pack was verified before the run. Nor is it a technical data sheet: adhesive behaviour belongs to the grade's documentation, and this specification is about mechanical survival and identification. The two touch only through the lot number.

The elements, in the order they get decided

1. The roll as built. Face width, length per roll, and the outside diameter that length produces. Both are locked together by the construction's total thickness, which sits in the grade data: double-sided constructions run 0.05 to 1.0 mm, foam tapes 0.4 to 3.0 mm, functional polyimide and polyester tapes 0.03 to 0.3 mm, masking, cloth and MOPP grades 0.08 to 0.3 mm, subject to the grade ordered. A specification naming length but not outside diameter cannot be checked at receiving.

2. The core. Material and inner diameter are declared fields, never defaults. Spiral paper, rigid plastic and metal tubes behave differently under the same stack load, and wall thickness decides whether the bottom row of a pallet arrives round. Inner diameter is stated as a number with its unit, commonly 25.4 mm (1 in) for hand dispensers and 76.2 mm (3 in) for applicator formats, because a wrong core is scrap that arrives on time. Core length against face width, flush, proud or recessed, decides whether rows sit directly together.

3. Winding direction and face orientation. Whether the web unwinds from outside or inside, whether the release liner or exposed adhesive faces out, and whether a printed side must present. An automated applicator cares more about unwind direction, roll hardness and tension than about the adhesive, since a web that surges at a splice places the next length late. This is the field most often left to inference on a first order, and the one that most often arrives wrong.

4. Separation, protection and edge control. Release liner on a double-sided construction, typically a PET film in the 25 to 100 µm range on what we convert, slip sheets between crepe-backed masking, and an explicit decision on whether rolls touch inside the carton. Coated and foil-backed webs abrade where they rub, so the interleave is part of the product. Add a shrink bag or end discs, and shoulder support against telescoping, the sideways shift of convolutions under a stack or an impact. Thick-coated and soft-foam rolls show edge damage long before the carton looks wrong, so the receiving question is edge condition, not box appearance.

5. Carton, count, markings and unit load. The count follows from the arithmetic below; the markings say what appears on the carton and the roll and what those codes open; the unit load says cartons alone or on a pallet, and whether goods travel as a full container or as groupage.

How a carton count is derived

The arithmetic runs in one direction. Outside diameter and face width fix one footprint; the carton's inner dimensions fix how many fit standing on edge and how many lie in rows; and the maximum carton gross weight your handlers will lift usually caps the count before the cube does. Lying rows stop rolls travelling and knocking edges; standing rows use the cube better and need spacers. Change the ordered length and the outside diameter moves, so the count moves with it; the pack is revision-controlled rather than remembered. Carton strength figures belong to the board maker's declaration under the standard you name, and are checked on incoming material, not published by us as though they were ours.

Moisture, heat and the tropical leg

Corrugated board loses stiffness as humidity rises, and a Southeast Asian sea leg sits inside that condition for days, sometimes with condensation on a container roof. Crepe and paper-backed grades take up moisture through the carton and change unwind behaviour. The practical answers are a poly barrier per carton or roll, desiccant placed against the container's sweating path rather than a carton wall, and a pallet that lifts the load off the floor. Nothing in the pack is treated to survive a voyage; the pack does that work.

Marking and the trace chain

Outer labels carry the purchase order reference, grade, size and length, quantity, weights, measurement, origin statement and the lot code, plus the handling marks the pack needs. The lot code is the useful part: for orders run here it resolves to the incoming material batch, the adhesive or stock lot, the slitting date and the inspection record, which lets a receiving team quarantine three cartons instead of a container. A pack without that link can be physically perfect and administratively useless; the chain is on our quality page.

Four readings that fail at the dock

Assuming the converter knows your unwind direction. Treating one rolls-per-carton figure as fixed across widths, when the count follows the outside diameter. Reading a thick carton as a strong carton, when board grade and flute carry the stack. And calling a printed part number traceability, when traceability is the record the number opens.

Send the roll format with length or outside diameter, the core your equipment expects, the winding requirement, your carton weight cap, the label fields your scan reads and the standard you want the pack verified against. Slit formats are on our slitting page and packaging-class grades on the masking and packaging tape page; the fields go onto a specification you sign before the run through our quote request.

FAQ

Is a pack specification a separate document from the technical data sheet?

Yes, and keeping them apart is what makes both usable: a data sheet describes what the adhesive and construction do, while the pack document describes the geometry, protection, count and marking of what arrives at your dock. Only the lot number connects the two, and a supplier who answers a packaging question with a data sheet has not answered it.

Commercial and process terms on this page are the questions a converter has to answer, not a standing offer. Order quantities, lead times, tooling charges, sample terms, freight and payment structures are confirmed at quotation against your drawing, your material and your destination, and only figures already published elsewhere on this site are stated as commitments.
