Carton Sealing Tape Specifications & Technical Data Sheet – Carton Sealing Tape for Bulk Packaging & Industrial Use

What This Sheet Can Confirm – and What It Cannot

This technical data sheet covers single-sided BOPP carton-sealing tapes with grade-confirmed acrylic, hot-melt, or solvent-based adhesive. It explains measurable properties, reporting conditions, surface compatibility, sample checks, and failure observations.

Grade-specific colors, adhesive systems, and roll formats belong in the carton sealing tape range. This sheet does not replace a controlled grade specification and does not cover masking, stretch film, strapping, pricing, or broad application troubleshooting.

Inside a Carton-Sealing Tape Roll

A typical construction combines BOPP film, a pressure-sensitive adhesive, and a release-treated non-adhesive surface. Printed grades may add ink or primer. Total thickness includes film and adhesive; backing thickness describes the film alone. Thickness can affect stiffness, break behavior, and unwind, but cannot establish carton adhesion by itself.

Data Fields to Record for Each Tested Grade

Use project-confirmed values unless a released specification exists. Every result should identify the grade, unit, method, conditioning, and acceptance status.

Item	Typical Value / Reference Range	Test Method or Condition	Notes
Backing / substrate	Grade-confirmed BOPP film	Material record and thickness check	Separate film from total thickness.
Adhesive system	Confirmed acrylic, hot melt, or solvent-based	Approved formulation record	Do not combine systems.
Total thickness	Reference: 38-60 um	ASTM D3652/D3652M or equivalent	State grade tolerance.
Roll dimensions	Project-confirmed width, length, core	Calibrated check	Separate nominal and minimum.
Peel adhesion	Project-confirmed, N/25 mm	Substrate, angle, dwell, pressure, speed	Steel is comparative.
Initial tack	Project-confirmed	One defined tack method	Methods are not interchangeable.
Static shear	Project-confirmed	Surface, area, load, time, temperature	Record failure mode.
Tensile / elongation	Project-confirmed, MD; TD if tested	ASTM D3759/D3759M or equivalent	Report force and % separately.
Unwind force	Machine grades: project-confirmed	Controlled speed and roll condition	Verify on intended tape head.
Temperature / storage	Grade-confirmed ranges	Defined conditioning and exposure	Separate application, service, storage.
Haze / UV	Tested clear grades or projects only	Defined optical or exposure method	No all-grade claim.

The Test Setup Behind Each Number

A standard number without the substrate, specimen direction, pressure, dwell, speed, temperature, humidity, area, load, and failure mode is incomplete.

Test Item	What It Checks	Suggested Method or Reference	Why It Matters	When To Request It
Thickness	Tape caliper	ASTM D3652/D3652M	Confirms construction variation	Grade approval or complaint
Peel adhesion	Removal force from a defined surface	ASTM D3330/D3330M or ISO 29862	Enables controlled comparison	Board, coating, or adhesive change
Initial tack	Early contact bond	ASTM D6195 or one internal method	Checks flap capture	Fast packing or low pressure
Static shear	Sliding under sustained load	ASTM D3654/D3654M on steel or agreed board	Checks creep and flap stress	Warm storage or heavy cartons
Tensile / elongation	Break force and stretch	ASTM D3759/D3759M	Shows film and tension sensitivity	Machine use or breakage
Unwind force	Force to remove tape from roll	ASTM D3811/D3811M or equivalent	Affects feeding and cutting	New tape head, speed, or roll
Carton trial	Actual linerboard behavior	Controlled 24 h / 72 h / 7 day protocol	Connects data to use	Before full use or material change

Reading Values Without Overreading Them

Peel adhesion measures removal force, initial tack measures early contact, and static shear measures resistance to sustained parallel load. Tensile strength is force at break; elongation is stretch before break. Results from different substrates, peel angles, dwell times, speeds, or conditioning are not directly equivalent.

Stainless steel provides a repeatable reference, while corrugated board varies in fiber, porosity, roughness, dust, moisture, printing, and coating. Clear-grade optical limits belong with the super clear BOPP carton sealing tape; print construction belongs with custom printed carton sealing tape.

A 7-Day Sample Verification Record

Condition tape and carton together. Apply the selected width and sealing pattern with controlled pressure, tension, overlap, and end-tab length. For machine rolls, record unwind tension, tape-head pressure, speed, alignment, and blade condition.

Inspect immediately, then after 24 h, 72 h, and 7 days. Record wet-out, bubbles, edge lifting, flagging, adhesive trace, surface shadow, gloss change, fiber tear, adhesive split, film tearing, residue observation, and joint movement. Repeat after relevant temperature, humidity, storage, transport, load, cargo-shape, equipment, or operator variation.

When a Good Number Still Produces a Weak Seal

The table links relative data movement to practical checks; it does not create universal pass/fail limits.

Data Point	If Too Low	If Too High	Risk in Application	Check Before Full Use
Total thickness	Low stiffness	Poor conformity	Edge lift or false comparison	Film, adhesive coat, tolerance
Peel adhesion	Early lift	Fiber or coating disturbance	Steel may not predict board	Actual carton and failure mode
Initial tack	Weak capture	Limited repositioning	Wrinkles or flap release	Pressure, speed, flap rebound
Static shear	Load creep	Poor wet-out can remain	Flagging or reopening	Area, load, temperature, time
Tensile strength	Film break	Higher cutting demand	Breakage or poor cut-off	Edge, blade, MD result
Elongation	Low shock tolerance	Excess stretch and recovery	Necking or edge lift	Tension after release
Unwind force	Loose feed	High feed load	Misfeed, break, low pressure	Actual dispenser or tape head
Temperature range	Poor wet-out	High-temperature softening	Lift, slip, bubbles, transfer	Tape and carton temperature

Keeping Stored Rolls Comparable to Tested Rolls

Store rolls in sealed original packaging under grade-confirmed temperature and humidity. Avoid sunlight, condensation, freezing, sustained heat, edge pressure, leaning stacks, and heavy compression. Quarantine rolls with distorted cores, crushed edges, telescoping, blocking, or water-damaged packaging.

Technical Questions

What information should carton sealing tape specifications include?

Backing, adhesive system, thickness, peel, tack, shear, tensile strength, elongation, unwind, dimensions, temperature, storage, method, and applicable grade.

What is the difference between a typical and guaranteed value?

A typical value is representative. A guaranteed value needs a controlled limit, sampling plan, tolerance, method, and acceptance rule.

Why is sample testing still necessary?

Cartons vary in fiber, coating, dust, moisture, roughness, flap stress, load, and application method, while laboratory panels are controlled.

Can storage or equipment change performance?

Yes. Heat, humidity, sunlight, roll damage, unwind tension, alignment, cutting, speed, and operator method can change contact and stress. Run a controlled trial.
