Rubber-based Adhesive Kraft Paper Tape

Introduction to Rubber-Based Adhesive Kraft Paper Tape

    Rubber-based adhesive kraft paper tape is a self-adhesive kraft paper tape made by coating kraft paper with a
    rubber- based pressure-sensitive adhesive.
 
It is renowned for its stable adhesive performance and durability.

 
Applications of Rubber-Based Pressure-Sensitive Kraft Paper Tape

 Primarily used in:
 

• ​Paper manufacturing processes in paper mills.

 

• ​Shoe material and leather splicing.

 

• High-temperature fabric lamination.

 

• Export carton sealing.

 
Classification of Pressure-Sensitive Adhesives

  Pressure-sensitive adhesives (PSAs) are categorized by their primary resin composition:
 

1. ​Rubber-Based PSAs

 

• ​Subtypes: Natural rubber or synthetic rubber.

 

• ​Composition: Rubber is the main component, supplemented by additives such as tackifiers, plasticizers, fillers, viscosity modifiers, vulcanizing agents, antioxidants, and solvents.

 

• ​Properties: Also called elastomeric PSAs. These adhesives initially used natural rubber but now include synthetic rubber and thermoplastic elastomers (TPEs). Common types:

 

• Natural rubber PSAs

 

• Synthetic rubber PSAs

 

• Thermoplastic elastomer PSAs

 

2. ​Resin-Based PSAs

 
Advantages of Thermoplastic Elastomer PSAs
 

• ​Eco-friendly: Aligns with modern demands for energy efficiency and reduced environmental impact.

 

• ​High production efficiency: Ideal for sustainable manufacturing.

 
Market Trends
 

• ​Synthetic and recycled rubber PSAs: Cost-effective options with steady market demand.

 

• ​Natural rubber PSAs: Despite being one of the earliest developed adhesives, they remain widely used for their superior quality and versatility in PSA products.

 
Kraft Paper
 

• ​Description:

 
    A high-strength packaging material, typically tan or brown. Semi-bleached or fully bleached variants may appear light brown, cream, or white.
 

• ​Applications:

 
  Base material for kraft paper tape.
  Cement bags, envelopes, asphalt paper, cable insulation, and protective packaging.
 
Color Variation Note

  Due to differences in raw material sources, production batches, seasons, and machinery, kraft paper rolls may exhibit     
  unavoidable color inconsistencies.

  Color uniformity within the same production batch typically ranges from ​50% to 80%.
