Double Sided Repulpable Tape

• Tape Description

  The superior performance of this Double Sided Repulpable Tape is rooted in its firm, water-soluble adhesive and high-strength construction:

  Water-Soluble Adhesive: The modified acrylic adhesive is firm and designed to fully dissolve during the pulping process. This feature ensures the tape is 100% repulpable, recyclable, and biodegradable.

  High Web Tension Performance: The adhesive uses high shear strength to prevent slippage even at high web tensions typical in printing and converting machinery. This avoids potential "blocking," where exposed adhesive gums up the adjacent paper layers, which can cause costly web breaks during unwinding.

  Contamination Prevention: By conforming to the TAPPI method UM-213, the tape guarantees that no contaminants are left in the paper mill broke waste, thus eliminating the need to separate the splice from the waste paper.

  The tape is available in various colors, including Blue, Clear, and Pink, often used for color-coding different splices (e.g., butt splices vs. overlap splices).

• Features & Benefits

  • 100% Repulpable: Entire structure (carrier and adhesive) dissolves in water. No need to remove splice joints from paper waste; prevents recycling contamination.
  • High Tack & Adhesion: Very high tack properties with excellent adhesion values. Bonds securely to a wide variety of paper grades.
  • Thermal Stability: Withstands high oven temperatures in web printing. Minimizes splice failure associated with heat stress.
  • High Shear Strength: Firm adhesive prevents slippage at high web speeds/tensions. Ensures paper rolls unwind smoothly without "blocking" or web breaks.
  • TAPPI Compliance: Passes TAPPI method UM-213. Meets the essential quality benchmark for repulpable materials.

• Tape Applications

  This specialized repulpable splicing tape is a critical component across the paper manufacturing and converting lifecycle for applications such as:

  • Overlap Splicing: Permanently joining paper rolls, including newsprint, tissue paper, and uncoated lightweight grades, during web processing.
  • Paper Re-reeler: Essential for creating continuous paper feeds in re-reeling operations.
  • Tabbing and Roll Closing: Used for securely tabbing the outer layer or closing paper rolls, ensuring the closure is also repulpable with the rest of the paper.

FAQ

Q1. What makes this tape “repulpable”?
A: It dissolves completely in water, allowing adhesive and backing to break down during repulping without contaminating paper pulp.

Q2: Why is this splicing tape better than regular double-sided tape for paper mills?
A: Regular tapes leave behind adhesive and plastic contaminants when recycled, potentially ruining the new paper batch. Repulpable splicing tape dissolves completely, eliminating labor costs associated with manually removing splice joints and guaranteeing clean, contamination-free paper recycling.

Q3: Can this tape withstand high heat from printing presses?
A: Yes. This specialized repulpable tape is formulated to withstand the high oven temperatures typically associated with web printing and converting processes, which minimizes downtime due to premature splice failure.

Q4. Can it handle high-speed machines?
A: Yes. Its high shear strength and tack prevent slippage under high tension and fast web speeds.

Q5. Is it safe for all paper grades?
A: Yes. It bonds well to most uncoated, lightweight, and tissue papers commonly used in printing and converting.
