BOPP Adhesive Tape Specification & Technical Data Sheet – BOPP Adhesive Tape for Carton Sealing & Industrial Packaging

Defined Technical Boundary

This document covers single-sided BOPP carton-sealing tape for laboratory comparison, incoming inspection, manual or automatic sealing, and qualification on corrugated board. It excludes kraft, masking, stretch, strapping, double-sided, cloth, electrical, and foam tapes. The data is not a universal specification for every adhesive grade.

For grade-level differences in clarity, adhesive chemistry, and roll format, review the transparent BOPP packing tape range before assigning a project specification.

Layer Build and Functional Roles

The construction combines a BOPP backing, a grade-specific pressure-sensitive adhesive, and a controlled release surface. The backing supplies strength, the adhesive controls tack, peel, and shear, and the release treatment affects unwind. Report total thickness, film thickness, and coat weight separately.

Reference Performance Window

Item	Typical Value / Reference Range	Test Method or Condition	Notes
Total thickness	Reference example: 40-65 um	ASTM D3652 or equivalent	Set nominal value and tolerance in the approved specification.
BOPP film thickness	Reference example: 23-32 um	Gauge or project-confirmed build	Do not infer from total thickness.
Adhesive coat weight	Reference example: 18-28 g/m2	Mass balance or approved method	Grade-specific value.
Peel adhesion to steel	Tested acrylic reference: 5-8 N/25 mm	180 degree peel after defined dwell	Actual carton adhesion may differ.
Initial tack	Grade-confirmed	Rolling-ball or loop tack	Comparative indicator only.
Static shear / holding power	Tested reference: >=24 h	Defined area, load, substrate, and temperature	Report failure time or test-limit pass.
Breaking strength	Tested reference: >=30 N/25 mm	Machine-direction tensile test	Slit-edge damage affects results.
Elongation at break	Reference example: 120-180%	Machine-direction tensile test	Read with breaking strength.
Application temperature	Reference example: 5-45 C	Tape and surface conditioned before use	Verify project limits.
Service temperature, haze, UV, shelf life	Project-confirmed	Defined grade and exposure condition	Do not assign universal values.

These BOPP tape technical specifications are reference ranges from identified acrylic grades. They become acceptance limits only when the grade, method, tolerance, and sampling rule are approved.

The yellowish BOPP packing tape test grade provides a practical example of how film thickness, coat weight, peel adhesion, holding power, and unwind data can be reported for an identified construction.

What Each Test Must Establish

Test Item	What It Checks	Suggested Method or Reference	Why It Matters	When To Request It
Thickness	Combined film and adhesive build	ASTM D3652 or equivalent	Confirms construction, not performance alone	Incoming inspection
180 degree peel adhesion	Removal force from a defined panel	ASTM D3330 or ISO 29862	Tracks adhesive consistency	Every approved grade; add carton testing
Initial tack	Rapid contact at short dwell	Controlled rolling-ball or loop tack	Indicates quick grab	Fast lines, cold use, stressed flaps
Static shear	Resistance under sustained parallel load	ASTM D3654 or ISO 29863	Shows cohesive holding behavior	Loaded cartons or warm storage
Breaking strength and elongation	Force and stretch at film failure	ASTM D3759 or ISO 29864	Relates to tearing and application stretch	Machine use or high flap stress
Unwind and carton qualification	Dispensing force and actual-surface behavior	ASTM D3811 plus controlled carton trial	Captures speed, fibers, dust, coating, and flap stress	Machine rolls and critical cartons

Comparable results require the same substrate, conditioning, pressure, dwell time, speed, load, and reporting format.

Reading the Numbers as a System

Thickness describes construction, not performance alone. Peel adhesion measures removal force after a defined dwell; initial tack describes rapid contact; holding power measures resistance to creep. Breaking strength and elongation must be read together. Haze matters only where optical clarity is controlled.

Where the Same Tape Behaves Differently

Recycled or rough corrugated board, dust, coatings, glass, metal, plastics, and low-energy surfaces create different contact conditions. Line speed, tape-head pressure, brake tension, cutter condition, alignment, and operator method also affect unwind and edge contact.

Conversion projects should also review BOPP jumbo roll technical requirements because coating uniformity, web flatness, core matching, unwind tension, and slit-edge quality affect finished-roll consistency.

Results vary with surface, load, cargo shape, coating, temperature, humidity, sunlight, storage, transport, equipment, operator method, and actual sample results.

Release-Gate Sample Qualification

Apply samples to the actual surface with the intended dispenser or machine. Record grade, surface, coating, temperature, humidity, pressure, equipment, operator, and load. Inspect at 24 h, 72 h, and 7 days where practical for peel behavior, edge lifting, bubbles, tearing, adhesive trace, surface change, fiber tear, flap spring-back, and loaded closure. Run a production trial before full use.

When Data Drift Becomes Application Risk

Data Point	If Too Low	If Too High	Risk in Application	Check Before Full Use
Film / total thickness	Stretching or splitting	Stiff roll or equipment mismatch	Tearing, poor cutting, unstable tracking	Dispenser and tape-head trial
Peel adhesion	Weak contact or edge lift	Fiber tear or difficult removal may increase	Open seam or surface change	Actual-surface checks at 24 h, 72 h, and 7 days
Holding power	Creep under flap stress	Adhesive balance may reduce wet-out on some surfaces	Flap reopening	Loaded-carton hold test
Breaking strength / elongation	Film failure or limited movement	Excess stiffness or stretch	Breakage or narrowed seal	Tensile test and full-speed run
Unwind / temperature response	Loose feed or slow bond build	Drag, film stretch, or warm creep	Wrinkles, misalignment, edge lift	Trial at intended speed and temperature

Use this packaging machine tape application guide after checking TDS reference values.

Keeping Stored Rolls Comparable

Store rolls upright in intact packaging in a clean, dry, shaded area. The 20-30 C and 50-70% RH condition applies only to the cited acrylic grade. Sunlight, condensation, heat, stacking pressure, damage, long storage, and transport cycles can alter roll condition. Re-test stock with an uncertain history.

Technical Evidence Pathways

Manufacturing variables such as coating uniformity, winding tension, slit-edge quality, and batch inspection should be reviewed against the site’s production and quality background before project-specific tolerances are approved.

Technical Approval FAQ

What should a BOPP adhesive tape specification include?

It should identify construction, dimensions, tolerances, peel, tack, shear, strength, elongation, unwind, temperature, storage, test methods, and data status.

What is the difference between a typical and guaranteed value?

A typical value is representative under defined conditions. A guaranteed value requires an approved method, tolerance, sampling plan, and acceptance rule.

Why can steel and corrugated-board adhesion differ?

Steel supports repeatable comparison. Corrugated board varies in fibers, roughness, dust, coating, and flap stress, so actual-board testing is required.

Do storage conditions affect performance?

Yes. Temperature, humidity, sunlight, storage time, roll pressure, damaged packaging, and transport can affect wet-out, unwind, and film condition.
