Double Sided Film Tape

Double sided film tape is a double coated tape made with a thin carrier film, pressure-sensitive adhesive on both sides and a removable release liner. The carrier gives better handling than unsupported adhesive film, especially when the material must be slit into narrow rolls, laminated onto printed films, or converted into small adhesive parts. For labels, overlays, displays and thin plastic sheets, its main value is controlled thickness, flat bonding, clean processing and a neat finished appearance.

Factory selection should not rely on tack alone. The tape should match the substrate, adhesive coat weight, liner release behavior and converting method. For thin overlay projects, one practical check is whether the laminated edge shows adhesive squeeze-out after pressing. Excess adhesive may affect printed films, display layers or clear plastic sheets. Typical sample checks include 24 h dwell observation, peel adhesion on the target material, liner release check, rewind tension check and die-cut edge observation.

Product Range

This category mainly covers PET and polyester film carrier structures. Standard options include clear double sided polyester film tape for transparent bonding, white film carrier tape for label backing, acrylic adhesive film tape for better aging and temperature stability, and rubber adhesive film tape for faster initial tack on selected smooth surfaces. It can serve tape converters, label processors, electronics assembly lines, graphic overlay producers and thin plastic sheet laminators.

Clear PET film tape, white film carrier tape, jumbo roll film tape and die-cut film tape parts can be selected according to transparency, backing coverage, converting width and assembly method.

Selection Guide

A good selection starts with the bonding surface and production process. Smooth PET, PC, PVC, coated paper, printed film and display films often work well with thin adhesive layers. Ink-heavy, textured or treated surfaces may need higher coat weight or another adhesive system after sample testing. If the finished part must stay flat, film thickness and liner stiffness should be checked together.

PET film carrier supports thin lamination, narrow slitting and clean die-cut edges. Polyester film carrier suits graphic overlays, nameplates and label fixing. Acrylic adhesive is preferred for long-term bonding and heat aging. Rubber adhesive gives quicker initial tack, but aging, temperature and residue risk should be tested. Glassine, PET and kraft liners should be selected by flatness, stiffness and release behavior.

Benefits

• Thin bond-line control helps laminated films, labels and overlays stay flat.
• Stable PET or polyester carrier reduces stretching during slitting, rewinding and kiss-cut processing.
• Cleaner converting supports narrow rolls, accurate die-cut shapes and controlled waste removal.
• Liner choices allow release force, peel feel and handling method to fit production.
• Custom coat weight helps balance quick positioning, final peel adhesion and edge appearance.

What Should Be Checked Before Selecting a Double Sided Film Tape for Thin Lamination?

Before selection, check substrate surface, total tape thickness, carrier film thickness and adhesive type together. PET or polyester carrier is usually selected when the application needs a flat bond line, stable thickness and clean handling during slit roll or sheet lamination. For printed overlays, plastic films, display parts and electronics labels, the adhesive layer should wet the surface evenly without visible edge build-up. Procurement and engineering teams often compare peel adhesion, holding power, liner type and release behavior together because roll-form performance may change after rewinding, narrow slitting or laminated sheet processing.

Applications

• Nameplate bonding for printed plastic, metalized film or coated label layers.
• Membrane switch assembly where stable thickness and clean die-cut edges are required.
• Graphic overlay lamination for control panels, printed overlays and surface films.
• Display lamination for thin film layers, spacer parts and display-related assemblies.
• Electronics label fixing where narrow rolls or kiss-cut labels are used in production.
• Plastic sheet bonding for PET, PC, PVC and other smooth sheets after sample testing.
• Thin industrial lamination for printed parts, protective layers and converted components.

Customization Options

Customization should be discussed around the production process, not only roll size. Width, length, core size, winding direction and rewind tension affect machine handling. Converters should confirm jumbo width, liner type, adhesive coat weight and roll hardness. Die-cut users should confirm drawing format, part spacing, liner extension, waste removal direction and kiss-cut depth before mass production.

How Does the Release Liner Affect Slitting, Kiss-Cut and Die-Cut Converting?

The release liner directly affects converting performance. In slit rolls, it must release smoothly without adhesive transfer, edge lifting or telescoping during rewind. In kiss-cut production, the blade cuts through the adhesive construction while the liner stays as the carrying base, so liner thickness, stiffness and release force must match cutting depth and waste removal. During a waste removal check, unstable release may cause small parts to lift with the waste matrix or sit unevenly on the liner.

FAQ

What is double sided film tape mainly used for?

It is mainly used for thin, flat and dimensionally stable bonding, including nameplate bonding, membrane switch assembly, graphic overlay lamination, display lamination, electronics label fixing and plastic sheet bonding.

How is it different from adhesive transfer tape?

Double sided film tape has a PET or polyester carrier between two adhesive layers. Adhesive transfer tape has no carrier, so film tape gives better handling, thickness control, slitting stability and die-cut processing.

Which release liner is better for die-cut converting?

It depends on part size, cutting depth and removal method. PET liner improves flatness and dimensional stability, glassine liner is common for roll processing, and kraft liner gives higher stiffness for some sheet or manual handling needs.

Can this tape be supplied as jumbo rolls and die-cut parts?

Yes. It can be supplied as jumbo rolls, custom slit rolls, rewound rolls, sheets, kiss-cut parts or die-cut parts. Final format should be confirmed by roll width, liner type, drawing, tolerance and application method.
