[0061] ​​​​​​​In some embodiments, the first anti-sticking zone has the following features: a) a length greater than 4 cm, preferably greater than 5 cm; b) a width of 1 to 4 cm, preferably 1 to 2 cm; and c) a distance to the nearest edge greater than 0 cm, preferably greater than 2.5 cm. The present inventors have surprisingly found that the above selection of size and location of the first anti-sticking zone allows the user to conveniently use a finger to unstick the tape without the aid of any tools and to remove the tape in the direction of the taping, while effectively protecting the carton face paper from being damaged, reducing carton breakage and enabling re-use. Furthermore, the above selection of size and location of the first anti-sticking zone also allows the taping effect of the tape to be unaffected, whereas if the first anti-sticking zone is of an inappropriate size and location, it can result in failure of the taping or the tape coming off during transport.

[0062] In some embodiments, the first anti-sticking zone further has the following features: d) a single or multiple rectangular or strip-shaped (e.g. two rectangles arranged on two different faces of a six-faced carton, respectively) arranged continuously or discretely; e) arranged such that the carton is taped with the tape passing through the first anti-sticking zone; f) arranged such that the edge through which the carton is taped is the edge of the face on which the first anti-sticking zone is located that is nearest to the first anti-sticking zone; and g) arranged such that the edge through which the carton is taped is substantially parallel to the first anti-sticking zone. Without being bound by any theory, it is believed that the above additional features of the first anti-sticking zone can provide further advantages, such as further improving the ease of un-sticking the tape, further improving the taping effect, reducing cost and / or facilitating automated production.

[0063] In some embodiments, the six-faced carton is a flat-top carton, preferably a GB / T 6543-2008 type 0201, 0202, 0203, 0204, 0205 or 0206 carton, and wherein the first anti-sticking zone is located on the left side face and / or the right side face.

[0064] In some embodiments, the six-faced carton comprises a first top flap, a second top flap, a first bottom flap and a second bottom flap, wherein a top outer edge and / or two side outer edges of at least one of the first top flap and the second top flap is provided with a second anti-sticking zone, and / or a top outer edge and / or two side outer edges of at least one of the first bottom flap and the second bottom flap is provided with a third anti-sticking zone. The present inventors have surprisingly found that the provision of the second anti-sticking zone and / or the third anti-sticking zone can further more effectively protect the carton face paper from being damaged, reduce carton breakage and enable re-use. Furthermore, the provision of the second anti-sticking zone and / or the third anti-sticking zone also allows the taping effect of the tape to be unaffected.

[0065] In some embodiments, the six-faced carton comprises a first upper flap, a second upper flap, a first lower flap, and a second lower flap, wherein the top outer edge and the two side outer edges of both the first upper flap and the second upper flap are provided with a second anti-sticking zone, and / or the top outer edge and the two side outer edges of both the first lower flap and the second lower flap are provided with a third anti-sticking zone.

[0066] In some embodiments, a fourth anti-sticking zone having a length of not less than 6 cm and a width of not less than 3 cm is provided on at least one face of the six-faced carton. In particular, the fourth anti-sticking zone can be used for providing a delivery slip, a product information label, and / or a coded label.

[0067] The present inventors have surprisingly found that the provision of the second anti-sticking zone and / or the third anti-sticking zone and / or the fourth anti-sticking zone can further more effectively protect the carton face paper from being damaged, reduce carton breakage, and enable re-use. In addition, the provision of the second anti-sticking zone and / or the third anti-sticking zone and / or the fourth anti-sticking zone also enables the sealing effect of the adhesive tape and the delivery slip, product information label, and coded label to be unaffected.

[0068] In some embodiments, the second anti-sticking zone and the third anti-sticking zone independently have the following features: a) a width of 1 to 6 cm, preferably 3 to 4 cm; and b) a single or multiple continuous or discrete arrangement of a rectangular or strip shape. In particular, the width of the second anti-sticking zone and / or the third anti-sticking zone refers to the width of a single rectangular or strip shape, rather than the width after splicing of multiple continuous rectangular or strip shapes. Without being bound by any theory, it is believed that the above additional features of the second anti-sticking zone and / or the third anti-sticking zone can provide further advantages, such as further improving the convenience of peeling off the adhesive tape, further improving the sealing effect, reducing costs, and / or facilitating automated production. The fourth anti-sticking zone preferably has a length of not less than 12 cm and a width of not less than 9 cm, which can better meet the needs of delivery slips, product information labels, and coded labels, and reduce damage to the carton face paper, thereby facilitating re-use.

[0069] In some embodiments, the first anti-sticking zone and the fourth anti-sticking zone further have the following feature: a peel strength of not more than 1 N / cm, preferably not more than 0.8 N / cm, as measured according to Test Method 1: Peel Strength of Anti-Sticking Zone.
