Hot Melt Double-Coated Packaging Tape combines a polymer film carrier with pressure-sensitive hot melt adhesive coated on both sides. A release liner protects the adhesive before use. The tape is designed for flexible packaging closure where controlled dimensions, clean application, and consistent roll handling are required.

Product Construction
Polymer Film Carrier
The polymer film provides the dimensional base for the tape. Its thickness and stiffness influence tape handling, edge stability, and conformity during packaging conversion.
Hot Melt Adhesive
Pressure-sensitive hot melt adhesive is coated on both sides of the carrier. The adhesive develops tack through contact and applied pressure, supporting efficient closure of compatible packaging films.
Release Liner
The release liner protects the adhesive during storage and converting. Liner thickness and release characteristics are selected according to manual application or automated dispensing requirements.

Key Product Advantages
Permanent Closure
The adhesive system is designed for permanent packaging closure, providing a firm bond after the tape is pressed onto a compatible film surface.
Fast Tack Development
Hot melt adhesive provides rapid initial tack after contact and pressure, supporting continuous packaging operations and short handling cycles.
Consistent Tape Profile
Controlled carrier and adhesive thickness help maintain a stable tape profile across the roll, supporting accurate slitting and predictable application.
Flexible Application
The film-based construction follows curved or flexible packaging surfaces while maintaining a defined adhesive layer for controlled bonding.

Technical Specifications

Substrate Compatibility
PE Film
The adhesive can be specified for polyethylene packaging films with different film structures and surface conditions. Substrate grade and surface treatment should be confirmed during product selection.
OPP Film
The tape can be configured for oriented polypropylene films used in flexible packaging. Adhesive selection considers surface characteristics and the required bond level.
Laminated Film
For laminated packaging, the adhesive is matched to the actual bonding layer rather than the complete laminate structure. Film construction and outer-layer material should be provided for evaluation.

Application Areas
Courier & Mailer Bags
Narrow-width tape formats support closure of flexible mailing bags and shipping envelopes where clean edge placement and permanent bonding are required.
Garment Packaging
The tape can be supplied in narrow widths for garment bags and protective film packaging. Adhesive position can be aligned with the bag edge and folding layout.
E-Commerce Packaging
Consistent roll dimensions and controlled adhesive placement support repetitive closure operations for flexible mailers used in order fulfillment.
Bubble Bags
The tape can be applied to flexible protective mailers with film-based outer surfaces. Width and adhesive position can be selected according to the closure area.

Selection Guide
Confirm Film Material
Identify the actual packaging film, including PE, OPP, or laminated construction. Surface treatment and film composition can affect adhesive performance.
Confirm Tape Geometry
Specify tape width, adhesive width, total thickness, and required adhesive position. These dimensions should correspond with the available sealing area.
Confirm Application Method
Manual application and automated dispensing may require different roll lengths, liner release levels, and core configurations. Application speed should also be considered.
Confirm Closure Design
Select the adhesive construction according to the required closure strength, handling time, and packaging structure. Permanent closure applications generally require stable adhesion after pressure is applied.

Production & Quality Checks
Coating Control
Adhesive coating thickness is monitored across the web to maintain a consistent adhesive layer and stable tape construction.
Slitting Accuracy
Slitting controls are applied to maintain specified tape width and clean edges. This supports stable feeding and accurate placement during converting.
Roll Winding
Controlled winding tension helps maintain roll shape and consistent unwinding. Core size and winding condition are matched to the intended dispensing method.
Adhesion Testing
Peel and holding tests can be conducted on specified packaging substrates. Test conditions are defined according to the required application and product specification.

Custom Specification
Tape Dimensions
Tape width, total thickness, adhesive thickness, and roll length can be configured according to packaging line requirements.
Adhesive Position
Left, right, or center adhesive placement can be selected to match bag construction, folding direction, and sealing geometry.
Liner Configuration
Liner material, thickness, and release level can be adjusted for the required handling and dispensing process.
Packaging Format
Core diameter, roll quantity, roll arrangement, and outer packaging dimensions can be specified according to storage and logistics requirements.

Information Required for Quotation
Provide the packaging film type, film thickness, tape width, adhesive width, required roll length, adhesive position, application method, and estimated annual volume. An existing specification sheet or material sample can also be supplied for product matching and sample evaluation.

FAQ
Is this tape suitable for permanent bag sealing?
Yes. The hot melt pressure-sensitive adhesive is designed for permanent closure of compatible flexible packaging films. Final adhesion depends on substrate construction, surface condition, and application pressure.
Can it be used on PE and OPP films?
Yes. Suitable adhesive configurations are available for PE and OPP packaging films. The actual film structure and surface condition should be confirmed before final selection.
Can the adhesive position be customized?
Yes. Adhesive placement can be configured on the left, right, or center of the carrier film to match the bag design and converting layout.
What roll lengths are available?
Typical roll lengths range from 25 m to 1000 m. The final roll length depends on tape width, core diameter, winding requirements, and dispensing equipment.
What details are needed to request a sample?
Provide the substrate material, film thickness, tape width, adhesive width, application method, and required roll length. A material sample can also be supplied for application evaluation.
