Abstract: A process for manufacturing a flat wrapping material includes the steps of (a) providing a circular roll of wrapping material, (b) compressing the circular roll of wrapping material into a flattened manner where the inner diameter of the circular roll of wrapping material is flattened to form two closely attached symmetric planes, and (c) applying an adhesive on the two closely attached symmetric planes to fixedly secure the two closely attached symmetric planes together.

Abstract: An easily tearable film and a method for preparing the same are described. The easily tearable film includes a unidirectionally tearable film with several cutting lines thereon. Each cutting line has a first end point and a second end point, and has a joining point with an imaginary straight line parallel to the tearing direction that passes the first end point of the next cutting line. The easily tearable film can be easily torn in a direction different from the tearing direction of the unidirectionally tearable film because of the cutting lines.

Abstract: A process for manufacturing easily portable and multi-layered adhesive tape roll is described. The flat piece of easily portable and multi-layered adhesive tape is formed by compressing the adhesive tape roll having circular shape or other shapes. The adhesive tape roll is compressed and cohered during the compressing step. A stiff interfacial layer, for example, having adhesion by adhering two innermost adhesive surfaces, by providing a stronger adhesion material, by inserting a stiff and solid material, or a stiff and solid material coated with a strong adhesion material, is applied to the symmetry plane of the adhesive tape during the compressing step. The preferential material of the high adhesion material is a cyanoacrylate adhesive or an epoxy adhesive.

Abstract: A faery adhesive tape is a transparent or translucent membrane substrate with constant width that is back-coated with glue, and multiple reels are produced and used as a tape. While producing multiple reels, the topic related describing intrigue is printed or tape-fitted at suitable interval on the substrate. The intrigue of said topic is expressed by segment with designs, letters, or excellent pictures and literary composition. Depending on the seriatim torn away of the adhesive tape, it will gradually deepen into the intrigue or gradually disclose the solution, build up the interesting effect of the expectation and pleasant surprise of users, and thus widen the scope of usage of the adhesive tape.

Abstract: The present invention relates to a tear-along structure of a sheet material, comprising a polygonal core lining, a roll of membrane substrate of the sheet material, wrapped around the polygonal core lining, and a slit cut at least one edge of the roll corresponding to a crest line of each corner of the core lining and toward said core lining. The slit is cut deeply into said core lining, wherein the substrate can be a normal membrane or with adhesive back tape, and then wrapped as a polygon or a multilateral shape.

Abstract: A process for manufacturing a flat adhesive tape comprises: providing a stiff interfacial sheet having a flat and solid form; surrounding the stiff interfacial sheet with a plurality of adhesive layers so as to form a roll of the adhesive layers with the stiff interfacial sheet positioned on a symmetric plane of the roll; and compressing the roll to form the flat adhesive tape. The stiff interfacial sheet can have a length slightly longer than a half-length of an innermost circumference of the roll of the adhesive layers. A layer of high adhesion material containing uncured high cross-linking epoxy or uncured high cross-linking cyanoacrylate can be provided between the stiff interfacial sheet and the adhesive layers. After compressing the roll of the adhesive layers, the high adhesion material is cured to form the flat adhesive tape.

Abstract: An easy-peeling and safe-dispensing tape roll for packing or sealing purpose is provided with a roll of continuous tape the rear side of which is provided with a layer of release coating and the opposite side thereof coated with a layer of adhesive. The tape is provided with a strip-like area at the middle of the lateral span thereof having no adhesive applied thereto, and the strip-like area is also provided with a plurality of spaced punch holes of various shapes, such as linear or circular and etc., so as to facilitate an operator to relocate and peel off the starting end of the cut tape each time in one aspect and to make the tape easily torn off with bare hands without a cutting blade of a dispenser in another aspect.
