BOPP Adhesive Tape Jumbo Rolls Technical Data Guide
BOPP adhesive tape jumbo rolls are often compared by thickness, adhesion, tensile strength, and roll size before a suitable grade is confirmed. This page is designed as a practical technical reference, helping buyers review key data in a simple format for easier specification comparison and converting evaluation.
Technical Data Interpretation
| Technical Item | Typical Data | What It Usually Indicates |
|---|
| Backing Material | BOPP film | Provides the base film structure for strength, surface support, and converting consistency. |
| Adhesive System | Water-based acrylic | Common for regular carton sealing, storage use, and general packaging environments. |
| Total Thickness | 36–65 mic common range | Lower values are usually linked with lighter sealing demand, while higher values support stronger closure performance. |
| Popular Thicknesses | 38 / 40 / 43 / 45 / 48 / 50 / 60 mic | These grades are often compared when matching cost level, sealing strength, and finished roll requirements. |
| Film Thickness | 20–28 mic typical | Film thickness affects tensile behavior, backing strength, and finished tape stability after slitting. |
| Adhesion to Steel | Approx. 4.0–4.5 N/25 mm | Useful as a reference for bonding level and initial closure reliability. |
| Tensile Strength | Approx. 28–45 N/cm | Important when stronger backing support is needed during handling, stacking, or transport. |
| Elongation at Break | Around 100% | Shows how the tape can absorb limited movement before breaking under tension. |
| Holding Power | Up to 24 h | Helps indicate whether the tape can maintain closure under steady load in normal conditions. |
| Jumbo Roll Width | 980 / 1280 / 1600 / 1620 mm | Usually selected according to slitting layout, machine width, and production planning. |
| Jumbo Roll Length | 4000 / 6000 m | Affects converting batch size, rewinding schedule, and output planning. |
| Core Size | 76 mm | Standard size used for industrial jumbo roll handling and rewinding systems. |
| Colors | Clear, brown, tan, printable | Common options for standard sealing and printed tape conversion. |
| Service Temperature | 0 to 60°C | Reference range for normal packaging and storage environments. |
| Applying Temperature | 10 to 40°C | Helps judge whether sealing performance is likely to stay stable during actual use. |
How to Read Thickness Data
| Thickness Range | Common Reading | Practical Reference |
|---|
| 36–40 mic | Lower range | Often reviewed for lighter cartons and routine packaging where sealing load is limited. |
| 40–45 mic | Balanced range | Commonly considered when a buyer wants a balance between material cost and sealing support. |
| 45–50 mic | Higher support range | Usually checked when better film strength and closure reliability are needed. |
| 50–60 mic | Stronger grade range | More suitable for demanding packing conditions or where stronger backing support is preferred. |
How to Read Adhesion and Tensile Data
| Data Type | What to Focus On | Why It Matters |
|---|
| Adhesion to Steel | Bonding level | Helps show whether the tape can build enough grip for stable carton closure. |
| Tensile Strength | Backing resistance under pull | Important when cartons may face handling stress, stacking pressure, or transport movement. |
| Elongation | Stretch before break | Useful when judging whether the backing can tolerate limited movement during sealing and handling. |
| Holding Power | Resistance under sustained load | Helps indicate closure stability over time instead of only initial sticking force. |
How Roll Size Data Affects Converting
| Roll Data | Technical Meaning | Converting Reference |
|---|
| Jumbo Roll Width | Determines slitting arrangement | Should match machine setup and target finished roll widths. |
| Jumbo Roll Length | Determines production volume per roll | Helps plan rewinding efficiency and batch output. |
| Core Size | Determines machine compatibility | Standard core size supports easier handling and system fitting. |
Quick Data Matching Guide
| If the main concern is… | Pay More Attention To… | Reading Suggestion |
|---|
| Lower material cost | Total thickness | Compare lower and mid-range grades first, but do not judge by thickness alone. |
| Stronger sealing support | Thickness + tensile strength | Review both values together instead of checking adhesion only. |
| Stable closure over time | Adhesion + holding power | A balanced data combination is usually more useful than one high value alone. |
| Slitting consistency | Roll width + film stability | Width planning and film structure matter for cleaner finished rolls. |
| Production efficiency | Roll length + width format | Check whether the roll format fits your converting schedule and machine layout. |
BOPP tape jumbo rolls are easier to compare when each technical value is read as part of a full specification set. Thickness, adhesion, tensile strength, and roll dimensions should work together rather than be judged separately. For most buyers, a balanced grade is usually more practical than selecting a material only by the lowest cost or the highest thickness.
FAQ
| Question | Answer |
|---|
| What does total thickness usually tell the buyer? | It usually helps show the overall grade level and whether the tape is better suited to lighter or stronger sealing demand. |
| Is higher adhesion always better? | Not always. A balanced combination of adhesion, tensile strength, and holding power is usually more useful than one value alone. |
| Why is tensile strength important in technical data? | It helps indicate how well the backing can resist pull and stress during handling, stacking, and transport. |
| Why should jumbo roll width be checked before production? | Because width directly affects slitting layout, machine setup, and finished roll planning. |
| Should specifications be judged by one single number? | No. It is better to compare thickness, adhesion, tensile strength, and roll size together. |
