Crosslinked Shrink Film has revolutionized packaging by combining durability, adaptability, and sustainability. Unlike traditional shrink films, crosslinking modifies the polymer’s molecular structure through chemical or physical methods, creating a three-dimensional network that enhances thermal stability and mechanical performance. At jtpackage, we leverage this technology to deliver solutions that meet modern industrial and environmental demands.

The Science of Crosslinking Crosslinking involves bonding polymer chains to form a resilient network, typically using peroxides, electron beams, or silane agents. For example, peroxides decompose under heat to generate free radicals that link polyethylene molecules, significantly improving heat resistance (up to 90°C long-term) and tensile strength. This process is critical for applications like electronics and pharmaceuticals, where packaging must endure temperature fluctuations and physical stress.

Advantages of Crosslinked Shrink Films

Enhanced Durability: Crosslinked films resist punctures and tears, ideal for sharp-edged products or heavy-duty logistics.

Thermal Stability: Maintain integrity in extreme cold or heat, making them suitable for cold-chain logistics and tropical climates.

Sustainability: jtpackage crosslinked films incorporate up to 30% post-consumer recycled (PCR) content, aligning with EU EPR and California’s plastic tax regulations .

Optical Clarity: High transparency and gloss enhance product visibility, crucial for retail-ready packaging.

Applications Across Industries

Electronics: Tamper-evident crosslinked films protect sensitive devices during shipping.

Food & Beverage: FDA-compliant films ensure safe packaging for perishables like frozen meals and fresh produce.

Pharmaceuticals: Moisture-resistant films comply with sterile packaging standards.

jtpackage Innovation in Crosslinking Our proprietary co-extrusion technology combines polypropylene (PP) and polyethylene (PE) layers, optimized for both performance and recyclability. By collaborating with recycling partners, we ensure films retain strength even with PCR materials. Recent breakthroughs include bio-based crosslinked films derived from sugarcane ethanol, offering carbon-neutral solutions for eco-conscious brands .
