In the vast world of flexible packaging, clear films often go unnoticed yet play a crucial role in showcasing products, protecting them, and ensuring consumer appeal. Among these, Transparent and Clear BOPP (Biaxially Oriented Polypropylene) film stands as a cornerstone, celebrated for its structural strength and adaptability. At Janvi Packaging, we delve deep into the technical nuances of these materials, engineering specific grades to meet the demanding requirements of printing, lamination, and adhesive applications.
What is Clear BOPP Film?
Clear BOPP film is a highly transparent plastic film made from polypropylene resin. The manufacturing involves stretching the extruded film in two directions (machine and transverse). This biaxial orientation significantly enhances its optical clarity, tensile strength, stiffness, and moisture barrier properties. The result is a highly versatile film that is lightweight yet incredibly durable.
Key Properties of Clear BOPP
- Excellent Transparency and Gloss: Offers high clarity, allowing the product inside to be perfectly visible, paired with a glossy surface that enhances aesthetic appeal.
- High Tensile Strength: Provides excellent resistance to tearing and stretching, ensuring package integrity during high-speed machining and transit.
- Moisture & Chemical Barrier: Naturally resists humidity, oils, and greases, extending the shelf life of the packed product.
- Cost-Effective Yield: Its low density provides a higher area yield per kilogram compared to many other polymers, making it an economically smart choice.
Technical Portfolio: Transparent & Clear BOPP Grades
We manufacture specialized Transparent BOPP grades (N-Series) specifically engineered for converters, label manufacturers, and tape producers. Below is a breakdown of our technical data capabilities.
1. Lamination & General Printing (N1 & N2)
N1 & N2: Non Heat Sealable Corona Treated
Thickness: 8µ - 50µ
N1 (One Side Corona Treated) and N2 (Both Side Corona Treated) films are the industry standard for high surface gloss and transparency. They offer excellent surface treatment retention and superior anchorage for inks and lamination adhesives. Widely used for reverse printing, paperboard lamination, posters, and book covers. N1 is also suitable for cold seal applications.
2. Pressure Sensitive Tapes & Release Liners
N1-AT & N1-TFT: PSA Tape Films
Thickness: 20µ - 50µ
Specifically designed for Pressure Sensitive Adhesive (PSA) Tape manufacturing. N1-AT provides excellent anchorage for various adhesives. N1-TFT features One Side Flame Treated and One Side Corona Treated surfaces, being 100% back-treatment free to ensure smooth unwinding of jumbo tape rolls.
N0: Untreated Release Film
Thickness: 12µ - 35µ
A completely untreated film providing excellent antistatic characteristics and moderate slip. Its very smooth surface acts as a perfect Release Liner for decorative laminates, protecting them from scratches while preventing sticking.
3. High Gloss Label Applications (LB Grades)
N1-LB & N2-LB: High Energy Treated Label Films
Thickness: 25µ - 50µ
These films boast low haze and brilliant clarity. They undergo High Energy Treatment specially designed for flawless surface printing. They offer exceptional anchorage and "get up" of inks on the treated side, and secure adhesion for hot melt/pressure sensitive adhesives on the other. Ideal for Wrap Around and PS Label applications.
4. Specialty: Anti-Slip, Holographic & Textile
N1-HCF: Anti-Slip Extrusion Lamination
Thickness: 15µ - 20µ
One side corona treated with the other side modified with an Anti-Slip / Anti-Skid property. Highly suitable for extrusion lamination with PP Woven Sacks to allow for stable stacking of bulk bags.
N1-LH & SM1: Low Haze Base & Modified Slip
Thickness: 10µ - 50µ
N1-LH (17-50µ) offers extremely low haze, ensuring a "water clear" appearance after embossing, making it the premier base film for Holography. SM1 (10-30µ) features a modified layer for exceptional slip and antistatic properties, widely used for high-speed flower overwraps and textile packaging.
N1-BG: Textile Bag Application
Thickness: 20µ - 50µ
Engineered with high surface gloss, excellent clarity, and optimal dimensional stability specifically for the manufacturing of clear textile bags and garment packaging.
Micron Selection Guidance
Depending on your application across our N-Series, the thickness of Clear BOPP profoundly influences processing:
- Ultra-Thin (8µ - 15µ): Perfect for paperboard lamination (N1/N2), light-duty wraps, and base films where cost optimization is paramount.
- Mid-Range (17µ - 25µ): The sweet spot for anti-slip woven sack lamination (N1-HCF), flower overwraps (SM1), and base holography (N1-LH).
- Heavy-Duty (25µ - 50µ): Crucial for rigid PSA tapes (N1-AT/TFT), durable textile bags (N1-BG), and premium high-energy treated labels (N1-LB).
Conclusion
Clear BOPP is not just a standard transparent plastic—it is a highly engineered substrate. Whether you need an untreated release liner, an anti-slip surface for woven sacks, or a high-energy treated film for flawless label printing, selecting the exact technical grade is essential for manufacturing success.
