Machine-Applied Finger Lift Bag Tape is a double-coated pressure-sensitive tape for automated bag converting. It uses a film carrier, adhesive layers and an extended release liner. The liner projects beyond the adhesive to create a defined dry edge for liner removal after the bag is produced.

The tape can be configured for PE, PP, OPP and selected multilayer films. Tape width, adhesive width, liner extension, construction thickness, roll length and core size are specified according to the bag structure and application process.

Product Structure
Film carrier
Supports adhesive layers and maintains tape profile during slitting, winding, and machine application.
Adhesive layers
Two functional surfaces provide bonding between the tape and bag film, selected based on substrate properties and closure performance.
Extended release liner
Extends beyond the adhesive track to form a defined finger-lift gripping area for controlled removal.

Machine Application
Roll feeding
Supplied in continuous rolls matching automatic feeding arrangements and machine dimensions.
Winding format
Consistent winding ensures smooth roll handling and stable feeding during high-speed production.
Tape placement
The adhesive track is accurately positioned along the designated sealing zone of the bag.

Bag Film Compatibility
PE film
Adhesive constructions engineered for polyethylene films used in mailing and poly packaging.
PP and OPP film
Formulations tailored to polypropylene surfaces and specific film treatment levels.
Multilayer film
Matched to laminated structures with distinct bonding surfaces.

Specification Options

Adhesive Selection
Permanent closure
Pressure-sensitive constructions designed to form the primary, secure bag closure.
Initial grab
Initial tack ensures reliable contact formation immediately upon application.
Surface matching
Formulations chosen according to film composition and surface treatment rather than general categories.

Finger-Lift Design
Dry edge
Liner extension creates a gripping area without adhesive exposure at the edge.
Extension size
Standard 3.2 mm per-side extension facilitates easy manual opening.
Liner release
Controlled release force allows smooth separation during opening.

Typical Applications
Poly Mailers
Integrated into the production of self-sealing plastic mailing bags.
Courier Bags
Applied to shipping bags requiring a secure adhesive closure and lift edge.
Garment Bags
Used in apparel packaging manufactured on automated converting lines.
General Poly Bags
Suitable for polyethylene and polypropylene packaging structures.

Manufacturing & Quality Control
Coating control
Adhesive coverage and width verified against strict dimensional tolerances.
Slitting control
Finished rolls produced with clean edge conditions and width accuracy.
Winding control
Roll tension and alignment monitored to ensure stable unwinding.
Inspection records
Checks cover dimensions, thickness, liner position, and application performance.

Selection Guide
For PE bags
Specify film type, thickness, surface condition, and required adhesive width.
For PP or OPP bags
Provide film structure and surface treatment details for adhesive matching.
For automatic production
Confirm core ID, roll length, tape width, and winding direction before ordering.
For new bag designs
Submit film specifications, sealing location, and target finger-lift geometry.
