Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

Example 1

As shown in fig. 1 and 2, the easy-to-tear tape 1 mainly includes a release layer 11 and an adhesive layer 12, wherein the release layer 11 is formed on any surface of the adhesive layer 12 and has a width greater than that of the adhesive layer 12.

The release layer 11 includes a release paper strip 111 and a plurality of protrusions 112 formed on the side edge of the release paper strip 111 and arranged at intervals, and the adhesive layer 12 is formed on the surface of the release paper strip 111; when the easy-to-tear adhesive tape layer is wound on any axial article in a laminated manner, the sides of the release layer 11 or/and the adhesive layer 12 perpendicular to the axial line of the article are defined as the respective side edges (namely long side edges), and the distance between the two side edges is the width of the easy-to-tear adhesive tape layer; in this embodiment, the release paper strip 111 has protrusions 112 formed on only one side edge, and the protrusions 112 are adjacent to each other in pairs so that two adjacent protrusions 112 are connected in a smooth transition manner; the shape of the protrusion 112 may be set according to actual needs, and is generally in a shape of a convex arc or a semicircle. Still define the side of tie coat 12 and the interval that corresponds the side from type note 111 to be d, then 0 is no less than or equal to d and is no less than 5mm, control the side of tie coat 12 like this and the interval that corresponds the side from type note 111, can take off from the type layer more conveniently when using, can reduce the dust accumulation in the air and influence the bonding effect in the outside of tie coat 12 after coiling the lapping moreover. Specifically, the bonding layer 12 is a tissue paper double-sided adhesive tape or a PE foam double-sided adhesive tape, so that the bonding strength can be ensured and the bonding layer is not easily peeled off during use, thereby avoiding the possibility of being recycled after use; the bonding layer 12 comprises a substrate and glue formed on two surfaces of the substrate, wherein the substrate is tissue paper or PE foam, and the glue is acrylic glue. In this embodiment, the substrate is PE foam, the thickness of the substrate is 0.02-0.05 mm, the thickness of the adhesive layer 12 is 0.14-0.17 mm, so that the thickness of the easy-to-tear tape is 0.2-0.5 mm, and the adhesion to the steel plate is more than 1300gf/inch (1 minute 180 degree peeling or 30 minutes 180 degree peeling) at 25 ℃ as measured under ASTM D3330 standard; tested under FINAT9 standard, the initial adhesion force is more than 2500gf/inch and the retention force is more than 1600gf/inch at 25 ℃; under the ZC test standard, the short-term temperature resistance can reach 100 ℃, the long-term temperature resistance can reach 80 ℃, and the adhesive has good adhesive force performance.

In this embodiment, the width of the release paper strip 111 is 15-30 mm, and the height of the protrusion 112 is 3-6 mm, so as to further ensure the easy-to-tear property of the adhesive tape. Manufacturing the easy-to-tear adhesive tape: a plurality of bonding layers 12 are bonded on any surface of release paper at equal intervals, the release paper is cut at the intervals to obtain release paper strips (the release paper forms release paper strips 111 with required sizes), and a wavy cutter is adopted to form bulges 112 during cutting.

Example 2

The package shown in fig. 3 and 4 mainly includes a box body 21, a first opening closure panel 22, a second opening closure panel 23, and the like.

The box body 21 is square, and can be set to be in a conventional shape such as a column shape, a prism shape and the like according to actual use requirements (shown in fig. 4 after being unfolded). The first sealing panel 22 is integrally formed at the mouth of the box 21, and can be folded to cover the whole mouth of the box 21 or partially cover the mouth of the box 21. A second opening closure panel 23 is also integrally formed at the mouth of the box body 21, and is arranged opposite to and fitted with the first opening closure panel 22; when the first sealing panel 22 is bent to be located at the opening of the box body 21, the second sealing panel 23 is bent to be tightly attached to the surface of the first sealing panel 22, so as to seal the packing box (when sealing, the second sealing panel 23 is attached to the outer side of the first sealing panel 22). In the present embodiment, the easy-open tapes 1 are attached to the outer edges of the surfaces of the first and

second closing panels

22 and 23 facing the box body 21 (in this case, the first and

second closing panels

22 and 23 are in the unfolded state, as shown in fig. 3) independently from each other, so that the adhesive strength between the first and

second closing panels

22 and 23 can be ensured. The second seals the panel 23 and still is formed with the easy strip 24 that tears rather than integrated into one piece, will easily tear the strip 24 and tear the back, and the second seals the panel 23 and is cut apart into two parts to realize the deblocking of sealed packing box.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention.
