Packing Tape Roll

Material Composition Assumptions

Based on a standard 48mm width by 50-meter length packing tape roll weighing approximately 25 grams:

• Polypropylene BOPP backing film: 18 grams (72%) - primary structural layer providing tensile strength
• Pressure-sensitive adhesive coating: 4 grams (16%) - synthetic rubber or acrylic formulation
• Paper core tube: 2.5 grams (10%) - recycled cardboard cylinder for dispensing
• Release liner packaging: 0.5 grams (2%) - protective wrapper during transport

Alternative material configurations include PVC backing films for heavy-duty applications, water-activated adhesives for enhanced security, kraft paper backing for eco-friendly options, and emerging cellulose-based films for sustainable packaging solutions.

Manufacturing Geography

China dominates global packing tape production due to integrated petrochemical supply chains and specialized converting equipment. The country’s grid intensity of 555 gCO2e/kWh significantly influences the carbon footprint of energy-intensive polymer film extrusion and adhesive coating processes. Manufacturing clusters in Guangdong and Jiangsu provinces benefit from proximity to raw material suppliers and established logistics networks for global distribution.

Regional Variation

Manufacturing Region	Grid Intensity	Estimated CCI Score	Adjustment vs Default
China	555 gCO2e/kWh	42	Baseline
Germany	366 gCO2e/kWh	38	-9%
United States	386 gCO2e/kWh	39	-7%
India	708 gCO2e/kWh	48	+14%
Brazil	85 gCO2e/kWh	28	-33%

Provenance Override Guidance

1. Primary polymer resin production data with specific energy consumption and feedstock origin documentation
2. Adhesive formulation details including synthetic content percentages and manufacturing energy requirements
3. Converting facility electricity consumption records with regional grid mix verification and renewable energy certificates
4. Transportation distance and mode documentation from raw material suppliers to final assembly location
5. End-of-life recycling rates and waste processing methods for specific tape material compositions

Methodology Notes

• CCI score represents cradle-to-gate emissions for a standard 48mm x 50m packing tape roll including raw materials, manufacturing, and packaging
• Scope 3 emissions dominate due to upstream polymer and chemical production processes requiring significant energy and petrochemical feedstocks
• Functional unit assumes single-use application for package sealing with disposal in municipal waste systems
• Score excludes use-phase impacts and end-of-life waste processing beyond initial disposal
• Data gaps exist for emerging biobased adhesive formulations and regional variations in polymer production efficiency
• Manufacturing process emissions vary significantly based on local electricity grid composition and production scale efficiency
