Corona Treated MOPP Film Master Roll For Adhesive Tape Coating

Corona Treated MOPP Film Master Roll For Adhesive Tape Coating

Used in downstream coating processes for applications such as: securing and bundling tapes for home appliances; tapes for fixing panels on refrigerators and air conditioners; bundling tapes for logistics pallets; resealable tapes for food bags; and base materials for carton carrying handles.
Target customer base: Manufacturers of adhesive products and tape-coating facilities.
End-use sectors: Refrigerators, washing machines, air conditioners, furniture, automotive components, large-item logistics, and food packaging.
Comparison with filament (fiber-reinforced) tape: MOPP-based tape offers a better price-to-performance ratio and leaves no loose fibers. While its ultimate load-bearing capacity and tear resistance are lower than those of fiberglass-reinforced tape, it is well-suited for medium-to-high-strength temporary securing applications.

4. OPP (Monoaxially Oriented Polypropylene—also referred to as TPP, a toughened, monoaxially oriented polypropylene film) is a base film specifically engineered for industrial strapping and securing tapes. It is oriented through stretching in the machine direction (longitudinal) only, resulting in exceptional longitudinal tensile strength and minimal elongation. It resists stretching and creep under load, making it the ideal substrate for tapes used in securing home appliances, pallet strapping, and multi-use sealing applications.

   Supplied as large master rolls with a single-sided corona treatment, the film offers a uniform and stable surface, making it compatible with both rubber-based and solvent-based acrylic adhesives. Once coated and slit into finished tapes, it can be removed cleanly without leaving adhesive residue. It serves as a highly cost-effective alternative to various types of filament (strapping) tapes.

   Key distinction: While BOPP (biaxially oriented polypropylene) offers balanced tensile strength in both directions, **MOPP (monoaxially oriented polypropylene) focuses on high longitudinal strength and low elongation, making it purpose-built as a substrate for strapping and securing tapes.1. Exceptional Longitudinal Tensile Strength with Minimal Elongation
   Molecules are oriented along the machine direction, ensuring minimal elongation under high tension. This prevents the strapping from loosening or "springing back" over time, making it ideal for securing large home appliances, palletized goods, and heavy-duty loads.
   2. Stable Corona Treatment for Uniform Adhesive Application
   Controlled single-sided corona treatment ensures consistent dyne levels. The film surface is pristine—free of "fish-eyes" (gel particles) and scratches—with tight thickness tolerances. This facilitates uniform adhesive coating, effectively preventing issues like delamination, skips, or uneven adhesive appearance.
   3. Temperature and Weather Resistance with Low Residue Upon Removal
   The film performs well across a broad temperature range (typically -10°C to 70°C, with short-term tolerance up to 80°C). When paired with the appropriate adhesive, it can be removed from surfaces—such as those found on refrigerators, sheet metal, plastics, or painted finishes—without leaving significant residue, meeting the requirements for temporary securing during the shipment of home appliances.
   4. Dimensional Stability for Smooth Processing
   Excellent control over thermal shrinkage ensures the film remains flat and aligned during coating, rewinding, and slitting. It is well-suited for continuous, high-speed production on large-scale coating and rewinding equipment.
   5. Clean Composition with Eco-Friendly Options
   Based on pure polypropylene, the film is available in versions compliant with RoHS and halogen-free standards. Unlike filament-reinforced tapes, it generates no fiber debris, ensuring a cleaner environment for downstream processing.
   6. Flexible Specifications; Master Rolls Available for Tape Manufacturers
   Thickness, width, corona treatment levels, and back-side anti-slip or release properties can be customized. We offer both full-width master rolls and pre-slit master rolls, with options for custom colors (e.g., transparent, milky white, or blue-tinted film) to meet specific customer requirements.
