Self Adhesive Cellulose Tape
OPALUS PACK is the manufacturer of self adhesive cellulose tape made with cellulose / cellophane film backing and a pressure-sensitive adhesive layer. It is developed for clean hand application, file sealing, document closure, label protection, envelope sealing, and light paper-based sealing where a thin, transparent, easy-tear tape is required.
- Backing: Cellulose / cellophane film.
- Adhesive: Natural rubber PSA or acrylic PSA.
- Color: Clear transparent.
- Thickness: Grade-dependent thin film range.
- Roll format: Slit rolls or custom lengths.
- Use: File sealing, document closure, label protection and light sealing.
Benefits of Biodegradable Sticky Tape
Product Overview
Self adhesive cellulose tape should be treated as a material-structure product, not as a broad eco tape, clear carton tape, or office stationery item. Its backing is cellulose film, also called cellophane film, commonly made from regenerated cellulose or wood pulp based material. This gives the tape a crisp feel, good transparency, and easier hand tearing than many plastic film tapes.
The pressure-sensitive adhesive bonds with finger pressure and needs no water, heat, or solvent activation. Natural rubber adhesive is selected for fast initial tack on paper, folders, envelopes, labels, and lightweight pouches. Acrylic adhesive is more suitable when cleaner appearance, aging stability, or controlled tack is required.
For repeat supply, check more than width and length. Backing thickness, coating balance, unwind force, peel adhesion, storage condition, and actual surface contact all affect use. Thin grades are commonly reviewed around 45-65 um total thickness. Sample rolls and retained samples help compare tack, clarity, peel response, and unwind behavior between orders.
Benefits
- Cellulose / cellophane film backing gives a thin, clear, crisp handling feel.
- Pressure-sensitive adhesive applies without water, heat, or extra activation.
- Natural rubber adhesive can provide quick grab on paper-based surfaces.
- Acrylic adhesive can improve visual cleanliness and aging stability.
- Hand tearable cellulose tape is convenient for manual light sealing.
- Retained samples help maintain tack, clarity, peel response, and unwind consistency.
When Should Natural Rubber or Acrylic Adhesive Be Selected for Self Adhesive Cellulose Tape?
Natural rubber pressure-sensitive adhesive is better when the tape needs quick grab, easy hand application, and reliable contact on paper, envelopes, file folders, labels, and light sealing surfaces. Acrylic adhesive is better when appearance, aging stability, or a cleaner adhesive profile matters more than aggressive initial tack. For cellulose film backing, the adhesive layer should match thickness, unwind force, and storage condition. Too much tack may cause blocking or difficult hand tearing; too little tack may cause lifting after sealing.

Applications
- File sealing where a clear, thin tape should not hide printed marks.
- Document closure for folders, record bags, archive packets, and envelopes.
- Envelope sealing where neat appearance and quick pressure bonding are required.
- Label protection when printed information needs to remain visible.
- Gift wrapping and light decorative packing that need easy hand tearing.
- Paper-based light sealing where thin cellulose film tape is preferred.
How Does Cellulose Film Backing Affect Hand Tearability, Transparency, and Sealing Performance?
Cellulose film, often called cellophane film, gives cellulose film tape a different feel from ordinary plastic tape. The backing is thin, clear, and naturally crisp, so it can usually be torn by hand or cut cleanly with a standard dispenser. This helps file sealing, label protection, envelope closure, and light sealing where the surface should remain readable. If the backing is too thin, it may wrinkle during unwinding; if the adhesive coating is unstable, peel consistency and clean edge performance may suffer.
FAQ
Is self adhesive cellulose tape the same as ordinary clear plastic tape?
No. It uses cellulose / cellophane film backing, while many clear tapes use plastic film backing such as BOPP. Structure, tearability, storage sensitivity, and handling feel are different.
Can this tape be used for heavy carton sealing?
It is better suited for file sealing, document closure, envelope sealing, label protection, gift wrapping, and light sealing. Heavy export cartons usually need stronger carton sealing tape.
Which adhesive is better, natural rubber or acrylic?
Natural rubber adhesive is useful for stronger initial tack and quick paper contact. Acrylic adhesive is preferred when cleaner appearance and aging stability are more important.
How should cellulose adhesive tape be stored?
Keep rolls in a cool, dry, shaded place, ideally around 18-25 C and 45-60% RH. Avoid sunlight, high humidity, floor storage, and heavy stacking pressure.
