Main features

  • Instant Acrylic Carton Closure
  • Split-Resistant BOPP Handling
  • Cold-Temperature Packaging Use

Product Description

Tartan Box Sealing Tape 305 is a 1.8 mil (0.046 mm) biaxially oriented polypropylene tape with a pressure-sensitive acrylic adhesive for general-purpose carton closure. The conformable backing wraps edges and rough recycled corrugate while resisting abrasion, moisture, scuffing, edge tear, and splitting during application. Instant adhesion requires no moisture, heat, or solvent activation, supporting smooth hand dispensing, manual dispensers, and case-sealing equipment. The clear or tan tape is intended for lightweight boxes exposed to minimal distribution hazards and performs in cold-temperature packaging work. It also resists yellowing, weathering, and UV exposure in lightweight carton-sealing service.

Key features

  • Conformable BOPP backing: The polypropylene film follows carton edges and rough recycled corrugate for a tight closure.
  • Instant acrylic adhesion: The pressure-sensitive adhesive requires no moisture, heat, or solvent activation.
  • Split-resistant handling: The backing provides edge-tear and split resistance during carton-sealing application.

Applications

Suitable for lightweight carton sealing, food and beverage packaging, recycled liner paper and fiberboard, cold-temperature use, bag closure, and cartons exposed to UV light and aging.

Technical Specifications

General Properties
Adhesive Layer
A layer that is applied to one surface or both to bind items together and resist their separation
Pressure Sensitive Acrylic
Color
The color
Clear and Tan
Film Thickness
Film thickness is the thickness of a backing film without taking into account any coatings or adhesive layers. It is measured in micron and the conversion factor to mil is 0.039.
0.025 mm
Total Thickness
Total thickness is taking into account all the films, coatings, adhesives, release liners and special layers and is the maximum thickness of a film or tape.
46 μm
Mechanical Properties
Adhesion Strength
Adhesion is the bond strength measurement of a coating to a substrate. When an adhesive is bonded to an item or surface, numerous physical, mechanical and chemical forces come into play, which may have an effect on each other.
16.2 Oz/in
Tensile Strength (Thin Film)
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture. To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
