Aluminum Foil Liner-Free Adhesive Tape

Product Introduction

Aluminum Foil Liner-Free Adhesive Tape is a specialized aluminum foil tape designed for industrial sealing, insulation, protection, and surface covering applications. The product uses aluminum foil combined with a polymer film substrate and adhesive coating to provide a practical liner-free construction with good adhesion, tensile strength, extensibility, and corrosion resistance.

Compared with conventional aluminum foil adhesive tape supplied with release paper, this liner-free design eliminates the need for a separate release liner, helping reduce release-paper waste and simplifying tape handling. It is also suitable for machine application and automated production processes where consistent winding performance and reduced tape breakage are important.

Jiangyin Biaotie Material Factory Co., Ltd. offers different adhesive, film, release-agent, thickness, and size configurations to meet application-specific requirements.

Product Features

• Liner-Free Construction: Eliminates release-paper waste associated with conventional aluminum foil tape.

• Aluminum Foil Base: Provides the functional properties expected from aluminum foil adhesive tape for insulation, sealing, and protective applications.

• Enhanced Corrosion Resistance: The polymer film lamination helps protect the aluminum foil from chemical and environmental effects.

• Improved Tensile Strength: Highly extensible polymer film improves the mechanical strength of the tape and reduces breakage during winding.

• Better Extensibility: The laminated structure provides greater flexibility and elongation than pure aluminum foil tape.

• Machine-Friendly Design: Improved winding performance makes the tape suitable for automated and high-efficiency production lines.

• Multiple Adhesive Options: Available with water-based, solvent-based, flame-retardant, two-component, and rubber adhesive systems.

• Flexible Material Configurations: BOPP, PET, PE, and other constructions can be selected according to application requirements.

• Customizable Dimensions: Different widths, roll lengths, and thicknesses are available for industrial applications.

Product Structure

The tape can be manufactured using different structural configurations according to the required performance.

One construction uses pure aluminum foil as the base material, with a silicone-based release agent applied to the reverse side or laminated film side and adhesive coated on the front surface before converting and winding.

Another construction combines polymer film with aluminum foil. The polymer film is first laminated to the aluminum foil, followed by release-agent treatment on the film side and adhesive coating on the aluminum foil side. This structure improves mechanical performance while maintaining the functional advantages of aluminum foil tape.

Technical Specifications

Technical values are based on the supplied product specifications. Actual performance may vary according to adhesive formulation, substrate, processing conditions, and application environment.

Dimensional Tolerance

The product is manufactured with controlled dimensional tolerances to support industrial converting and application requirements:

• Aluminum foil thickness tolerance: ±0.005 mm

• Total thickness tolerance: ±0.01 mm

• Width tolerance: ±0.5 mm

• Length tolerance: ±0.2 m

These tolerances help provide consistent roll dimensions for downstream processing and automated application.

Primary Applications

Aluminum Foil Liner-Free Adhesive Tape is suitable for a range of thermal insulation, sealing, protection, and industrial surface applications.

Refrigeration & Thermal Insulation

The tape can be used for long-term thermal insulation and sealing in refrigeration systems, including refrigerator and freezer evaporators, condenser pipelines, and related components. Its aluminum foil structure provides a practical surface layer for insulation and sealing applications.

Condenser Tube Protection

The tape can be applied for wrapping thin copper condenser tubes. Its laminated construction provides a protective layer while maintaining the flexibility needed for wrapping and covering cylindrical components.

Automotive Interior Protection

The product can be applied to automotive interior components, including PS boards and other plastic panels, where an aluminum foil adhesive layer is required for surface protection and functional covering.

Home Appliance Industry

The tape is suitable for applications involving refrigerators, freezers, cooling systems, and other household appliances that require aluminum foil-based adhesive materials.

Infrastructure Fire Protection

Selected flame-retardant adhesive configurations can be considered for applications involving infrastructure fire protection requirements, subject to the specific performance requirements and applicable standards of the project.

Advantages for Automated Application

Traditional aluminum foil tape can be susceptible to tearing or breakage during high-speed winding and machine application, particularly when the substrate relies heavily on pure aluminum foil. The polymer film reinforcement used in this product improves extensibility and tensile strength.

This makes the tape better suited to automated production environments where continuous feeding, stable winding, and reduced material interruption are important. The liner-free structure can also simplify handling by eliminating separate release-paper removal during application.

Storage Conditions

Store the tape in a cool and dry environment at room temperature.

• Storage temperature: -5°C to 40°C

• Relative humidity: below 80% RH

• Keep away from direct sunlight.

• Avoid prolonged exposure to heat sources.

• Keep the packaging properly sealed during storage.

Appropriate storage conditions help maintain adhesive performance and product quality throughout the recommended shelf life.

Shelf Life

• Water-based adhesive: 6 months

• Flame-retardant adhesive: 6 months

• Solvent-based adhesive: 12 months

• Rubber adhesive: 12 months

Shelf life should be considered from the date of manufacture when the product is stored under the recommended conditions.
