High-Tack Double-Coated Packaging Tape is a permanent sealing tape for flexible packaging films. It combines a film carrier with pressure-sensitive adhesive on both sides and a release liner for protection before application. The construction is specified by carrier, adhesive, thickness, width, roll length and adhesive position to match packaging materials and converting requirements.

Product Construction
Film Carrier
PET or polymer film forms the dimensional base of the tape. Carrier thickness influences flexibility, handling and slitting stability.
Permanent Adhesive
The adhesive layer is coated on both sides of the carrier. Adhesive selection is matched to the film surface, bonding area and required sealing condition.
Release Liner
The liner covers the adhesive before use. PET, BOPP and paper-based liners can be selected according to release force, handling and converting requirements.

Key Advantages
High Initial Tack
High initial tack allows the adhesive to establish contact quickly after pressure is applied to the packaging film.
Permanent Bond
The adhesive remains attached after closure, making the tape suitable for packages intended for fixed sealing.
Controlled Dimensions
Defined tape width, thickness and winding dimensions support accurate placement during packaging conversion.
Process Compatibility
Tape construction can be matched to manual application, intermittent processing or continuous packaging operations.

Technical Specifications

Packaging Materials
PE and HDPE Films
Polyethylene films are widely used for mailing bags, garment bags and flexible packaging. Adhesive selection is based on film surface and formulation.
OPP and BOPP Films
Polypropylene films require an adhesive construction matched to the surface condition and treatment level.
Laminated Structures
For laminated films, the bonding surface is evaluated directly because different outer layers can require different adhesive constructions.

Typical Applications
Courier and Mailer Bags
The tape forms the permanent closure area on flexible mailing and shipping bags.
Garment Packaging
Self-sealing garment bags can use the tape to close the flap without adding a separate closure component.
E-Commerce Packaging
The tape supports repeatable closure of flexible fulfillment packaging in manual and production environments.
Bubble and Protective Bags
The adhesive bonds the closure flap to flexible protective packaging while maintaining a thin sealing profile.

Application Method
Manual Sealing
Remove the release liner, align the flap and apply firm pressure across the complete bonding area.
Semi-Automatic Processing
Tape width, roll length, winding condition and adhesive position should correspond to the feeding and application process.
Continuous Production
Stable winding and controlled liner release support continuous feeding during bag-making and packaging conversion.

Selection Criteria
Substrate
Confirm film type, thickness, surface treatment and additives before selecting the adhesive construction.
Bonding Area
Tape width should correspond to the flap geometry and available bonding surface.
Closure Requirement
Select permanent sealing tape when the package requires a fixed adhesive closure after application.
Operating Conditions
Application temperature, storage conditions and expected handling should be considered when defining the final specification.

Custom Specification
Tape Dimensions
Width, total thickness and roll length can be adjusted to match package dimensions and converting requirements.
Adhesive Position
Left, center or right adhesive placement can be selected according to the package structure and sealing direction.
Liner Configuration
Liner material, thickness, color and release characteristics can be defined for the intended application process.

Quality Control
Incoming Materials
Carrier film, adhesive materials and release liner are checked against defined material specifications before production.
Process Control
Coating, lamination, slitting, width, thickness and winding parameters are monitored during tape conversion.
Finished Roll Inspection
Finished rolls are inspected for dimensions, adhesive position, winding condition and agreed appearance requirements.

Specification for Inquiry
Provide the packaging film type, tape width, total thickness, roll length, adhesive position, package structure and application method. For production-line use, include the required roll configuration and application conditions. Testing with the actual packaging film provides the basis for confirming adhesive construction and final specifications.

FAQ

What is High-Tack Double-Coated Packaging Tape?
It is a double-coated pressure-sensitive tape with high initial tack for permanent closure of compatible flexible packaging films.

Which packaging films are commonly used?
PE, HDPE, OPP and BOPP films are common substrates. Final adhesive selection depends on the actual film surface.

Can the tape dimensions be customized?
Yes. Width, thickness, roll length and adhesive position can be adjusted according to the package design and converting process.

Can it be used for continuous packaging production?
Yes. Tape dimensions, winding condition, adhesive position and liner release can be configured for the intended production process.

What information is required for specification confirmation?
The main requirements are film type, tape width, thickness, roll length, adhesive position, package structure and application method.
