Document Type and Number:
Japanese Patent JP6095524
Kind Code:
B2
Abstract:
The present invention provides an adhesive tape that ensures sufficient adhesion to a water-repellent surface having a contact angle with pure water of 140 degrees or more even by an instantaneous slapping motion, and that prevents its adhesive from adhering to cutters during processing (cutting, punching, etc.). Specifically, the present invention provides an adhesive tape used for bonding to a water-repellent surface of a packaging material, the water-repellent surface having a contact angle with pure water of 140 degrees or more;
(1) the adhesive tape comprising a base material layer made of foam, and a natural rubber-based adhesive layer;
(2) the base material layer having a density of 0.38 g/cm 3 or less and a thickness of 1 mm or less; and
(3) the natural rubber-based adhesive layer having:
(i) a weight per unit area of 35 g/m 2 to 65 g/m 2 ;
(ii) a ball number of 10 or more in a ball tack test specified in JIS Z0237; and
(iii) a holding power of 100 seconds or more in a holding power test specified in JIS Z0237.
