Kraft Paper Aluminum Coils for Pipe Insulation

2026-06-12

Kraft paper aluminum coils are a key material for moisture and vapor barrier applications in industrial pipeline insulation systems. As a leading manufacturer specializing in the aluminum insulation cladding products, our kraft paper laminated aluminum coils are specifically optimized for both hot and cold pipeline insulation applications. Through high-temperature composite molding of aluminum base and waterproof kraft paper, they perfectly address the industry pain points of traditional aluminum insulation materials, such as easy vapor permeability and susceptibility to moisture and mold growth in the insulation layer. Unlike ordinary bare aluminum coils, Haomei kraft paper aluminum coil feature a dual structure of "metal protection + paper vapor barrier," making them the mainstream standard material for pipeline insulation projects in chemical, HVAC, municipal, and energy industries.

Kraft paper aluminum coils utilize a mature alloy system specifically designed for pipeline insulation, with core grades including 1060 pure aluminum and 3003 aluminum-manganese alloy, fully complying with ASTM international industrial material standards. The 1060-H14/H18 substrate boasts high purity, uniform toughness, and excellent bending performance, with no cracking or delamination issues. Its cost-effectiveness is significant, making it suitable for most civil and general industrial hot and cold pipeline insulation projects. The 3003 aluminum-manganese alloy substrate inherently possesses rust and corrosion resistance, higher structural strength, and significantly upgraded salt spray and moisture resistance, making it suitable for harsh pipeline conditions such as coastal areas, chemical plants, and high-humidity factories. Standard thicknesses range from 0.2–1.5mm, with customized specifications available to meet various pipe diameter wrapping requirements.

Leveraging mature rolling composite technology, we have categorized kraft paper aluminum jacketing roll into three core categories: smooth, embossed, and corrugated, offering differentiated adaptations to various working conditions.

Smooth kraft paper-coated aluminum coil have a smooth surface, extremely high wrapping fit, and excellent joint sealing, suitable for indoor regular pipelines and precision HVAC pipeline insulation, resulting in a neat and aesthetically pleasing finished product.

The embossed kraft paper coated aluminum coil features a uniform orange peel texture, effectively enhancing the board's rigidity and dent resistance. It is slip-resistant and abrasion-resistant, making it less prone to deformation during outdoor and high-altitude pipeline construction, suitable for various complex outdoor insulation scenarios.

The corrugated kraft paper coated aluminum coil utilizes a corrugated forming process, resulting in structural strength, wind pressure resistance, and tensile strength far exceeding that of flat aluminum. It is also pressure- and impact-resistant, specifically designed for insulation of large factories, long-distance high-altitude pipelines, and heavy-duty pipelines.

The core advantage of the kraft paper coated aluminum coil is its integrated composite structure; the kraft paper and aluminum layer are tightly bonded, without delamination or separation, providing excellent vapor barrier, moisture-proof, and waterproof capabilities. The core cause of pipeline insulation system failure is often moisture penetration, leading to waterlogging of the insulation cotton, cooling failure, and pipeline corrosion. This product completely blocks external moisture from entering the insulation layer, eliminating condensation, mold, and freeze-thaw damage. It is also suitable for both hot and cold pipeline applications, remaining undelaminated at high temperatures and resistant to cracking at low temperatures, demonstrating exceptional adaptability.

Compared to ordinary aluminum insulation coils, the kraft paper coated aluminum coil offers higher construction tolerance. The paper surface effectively cushions impacts during construction, protecting the aluminum substrate. The board's excellent flexibility simplifies cutting, bending, and wrapping, significantly improving construction efficiency. Furthermore, the product requires no painting or maintenance, is resistant to aging, and has a long service life, ensuring long-term stable insulation, cold insulation, and energy-saving effects for pipelines. This effectively reduces post-construction maintenance costs. With its high stability and cost-effectiveness, it is exported to many countries and regions worldwide, making it an essential core material for pipeline insulation projects.
