Big Roll High Tension Force BOPP Tear Tape For High Speed Machine Inner Core 152mm

1: Introduction 

Tear tape, also known as tearstrip or tear-off ribbon, is a narrow adhesive tape used to open packaging. The backing is often a narrow oriented polymer such as polypropylene but other polymers, yarns, and filaments are also used. Many tear tapes use a pressure sensitive adhesive but others have a heat-activated adhesive system.

Tear tape is usually attached to the inner surface of packaging: paper, paperboard, corrugated fiberboard or plastic film. It is used on common non-durable fast-moving consumer goods such as soft drinks, groceries or toiletries, as well as tobacco products such as cigarettes and cigars, to aid the opening of the packaging. It is also used in courier envelopes and corrugated boxes. Tear tape serves as an easy opening device for the consumer, where it obviates the need for opening tools such as scissors or knives, or the use of excessive force. Tear tape provides a guide on the tear area, thereby allowing more precise opening which reduces product spillage.

Self-adhesive tear tape is created to facilitate the opening of the package to avoid damage and other mechanical effects. This narrow strip makes it easy to fix the packaging material and at the same time it is not interfering with the visual appearance of the product.

Pressure-sensitive adhesives are designed with a balance between flow and resistance to flow. The bond forms because the adhesive is soft enough to flow, or wet, the adherend. The bond has strength because the adhesive is hard enough to resist flow when stress is applied to the bond. Once the adhesive and the adherend are in proximity, there are also molecular interactions such as van der Waals forces involved in the bond, which contribute significantly to the ultimate bond strength. PSAs exhibit viscoelastic (viscous and elastic) properties, both of which are

used for proper bonding.
