As shown in fig. 1 to 5, the utility model provides an easily tear PET sticky tape, include drum 1, convolute PET baseband 2, adhesive layer 3 on the drum 1, the coating of adhesive layer 3 is in the positive centre on the 2 internal surfaces of PET baseband, the width on adhesive layer 3 is less than the width of PET baseband 2, two sides on adhesive layer 3 along length direction respectively with two sides of PET baseband 2 along length direction correspond parallelly, PET baseband 2 is equipped with easily to tear structure 4 along width direction with predetermineeing the spacing distance.

Specifically, the cylinder 1 may be a paper cylinder or a plastic cylinder 1, and the PET base tape 2 is made of Polyethylene terephthalate (PET). The base band made of the polyethylene glycol terephthalate has good mechanical property, good durability, stable chemical property, high transparency, good glossiness and good sanitary safety. The adhesive layer 3 is a structural layer formed by coating an adhesive on the PET base tape 2 through a coating process, and the material or formulation of the adhesive is determined according to actual needs, and is preferably acrylic adhesive. The specific processes involved in the coating process are common processes and are not described herein.

In this embodiment, the adhesive layer 3 is coated on the inner surface of the PET base tape 2 at the center, and the width of the adhesive layer 3 is smaller than the width of the PET base tape 2, so that a corresponding coated area is formed in the middle of the PET base tape 2, and an uncoated area is formed in the side edge area of the inner surface of the PET base tape 2. Due to the viscosity of the coating area, adhesion to the surface of the target object can be realized; and because the two side regions of the inner surface of the PET base band 2 are not sticky and leave gaps, a user can easily uncover any side of the PET base band 2, then find the adhesive tape port and uncover the adhesive tape for use. Since any side of the PET base tape 2 has no adhesive and cannot be attached to the rest of the adhesive tape, the adhesive tape port can be easily found in the next use. Simultaneously, also can satisfy the different use preferences of left-handed person or right-handed person, promote the use of sticky tape and experience.

Preferably, the width of the PET base tape 2 is not less than 1 cm. In the present embodiment, the adhesive layer 3 is coated on the middle of the PET base tape 2, so the width of the PET base tape 2 is not too narrow, and the minimum width of the PET base tape 2 is limited to 1 cm. In particular, in order to satisfy the requirement of the adhesive property of the tape, the width of the adhesive layer 3 is not too narrow; meanwhile, in order to avoid waste of the adhesive and improve the easiness in finding the end opening of the adhesive tape, the width of the adhesive layer 3 is not too wide, and the width of the adhesive layer 3 is preferably limited to 3/5-9/10 of the width of the PET base band 2.

In addition, two sides of adhesive layer 3 along length direction respectively with two sides of PET baseband 2 along length direction correspond parallelly, can be so that adhesive layer 3's shape is regular, and the distribution position of adhesive is reasonable, helps improving the utilization effect of adhesive, also helps improving the off-the-shelf pleasing to the eye degree of sticky tape.

Further, the tear structures 4 are provided on the PET base tape 2 at predetermined intervals in the width direction. The PET baseband 2 sets up easily along the width direction interval promptly and tears structure 4 for promote the off-the-shelf easily degree of tearing of sticky tape. Wherein, the preset spacing distance is preferably 3-6 cm. This optional range is better able to meet most of the usage needs. When the adhesive tape tearing device is used, a user can obtain the adhesive tape segments with specific lengths only by tearing the easy-tearing structure 4, the operation is simple and convenient, and the lengths of the torn adhesive tapes are easy to control accurately.

Here, it should be noted that the easy-to-tear structure 4 may be disposed on the PET base tape 2, and then the adhesive layer 3 may be applied. Therefore, the adhesive layer 3 is prevented from being coated in a spacing block mode, the difficulty of the production process of the adhesive tape is reduced, and the production efficiency is improved. Easily tear structure 4 simultaneously and cross PET baseband 2 in the width direction, run through PET baseband 2 in the thickness direction of PET baseband 2, also improved the easy tearing nature of sticky tape.

As shown in fig. 2 and 3, in a preferred embodiment, the tearable structure 4 is a through hole 41 penetrating through the PET base tape 2, and the shape of the through hole 41 is a diamond or a rectangle. The diamond or rectangular shape is simple and easily formed across PET, while allowing easy and quick tearing of the finished tape.

More preferably, the interval between the through holes 41 is 1 to 2 mm; the interval refers to the distance between the nearest vertexes of adjacent diamond holes or the distance between the nearest sides of adjacent rectangles. When the through hole 41 is in a diamond shape, the long diagonal line of the through hole 41 is parallel to the width direction of the PET base tape 2; when the through-hole 41 has a rectangular shape, the long side of the through-hole 41 is parallel to the width direction of the PET base tape 2. The long diagonal of rhombus hole or the long limit in rectangular hole are parallel with 2 width direction in PET baseband, can further promote the off-the-shelf easy degree of tearing of sticky tape, improve the convenient to use nature and the work efficiency of sticky tape.

In another preferred embodiment, as shown in fig. 4, the tear structure 4 is a line of perforations 42. The sawtooth hole lines 42 are easy to set, the corresponding production process is mature, and the sawtooth hole lines 42 enable the end of the adhesive tape to be neat and attractive in shape.

When the adhesive tape is used, if the adhesive tape needs to be torn off, the adhesive tape only needs to be torn off along the through hole 41 or the sawtooth hole line 42, the operation is simple and convenient, and the work efficiency is improved.

In this embodiment, provide an easily tear PET sticky tape, through the adhesive layer 3 that the internal surface coating width is less than 2 width of PET baseband in 2 middle parts of PET baseband, form the space on 2 both sides limits of PET baseband, satisfy the adhesion and the requirement of easily taking off to the sticky tape for the sticky tape port is easily found, and the sticky tape is easily opened additional, and operator's finger can not be infected with the adhesive. Simultaneously, the interval sets up easily tears structure 4 on PET baseband 2, can promote the easily tearing nature of sticky tape, can tear the sticky tape of accurate length fast. Therefore, the use convenience of the adhesive tape is greatly improved, a lot of workload is reduced, and the working efficiency is improved.

As an optional modification, as shown in fig. 5, a pattern layer 5 is further provided between the adhesive layer 3 and the inner surface of the PET base tape 2. Specifically, the pattern layer 5 is disposed on the inner surface of the PET base tape 2 in a coating or printing, or the like manner before the adhesive layer 3 is applied. The pattern layer 5 may be a specific mark, pattern, text, etc. for improving the aesthetic appearance of the adhesive tape or for publicity (e.g. the mark is the name of a certain company).

As an alternative modification, as shown in fig. 6, the adhesive pattern of the adhesive layer 3 is a grid pattern.

As an alternative modification, as shown in fig. 7, the adhesive pattern of the adhesive layer 3 is a straight stripe.

As an alternative modification, as shown in fig. 8, the adhesive pattern of the adhesive layer 3 is wavy.

When the adhesive layer 3 is coated, specific adhesive lines (such as grid, straight strip and wave) are arranged, so that the surface area of the adhesion surface of the adhesive layer 3 can be increased, and the adhesion is improved; the consumption of the adhesive layer 3 can be saved, which is beneficial to improving the economic benefit and is more environment-friendly.
