Sealing tape is primarily made from BOPP biaxially oriented polypropylene film, which is then heated and evenly coated with a pressure-sensitive adhesive latex. The primary component of this latex is butyl acetate.
Sealing tape has strong adhesion to various applications, including varnishing, polishing, calendering, and PP lamination, including PET and PP transparent boxes, films, bonding non-woven fabrics, cosmetic packaging, food packaging, cigarette packaging, and Tetra Pak beverage packaging, edge banding for assembled furniture, sealing for the electronics industry, automotive interiors, headlight manufacturing, and windshield assembly, non-woven sanitary napkins, diapers, insoles, household items, coated composite label paper, double-sided label tape, mouse traps, fly paper, laminating wood floors and carpets, and adhesive bandages.
Hot-melt pressure-sensitive adhesive (HMPA) is a new type of pressure-sensitive adhesive. It's primarily made by heating a mixture of synthetic rubber, resin, and rubber oil into a liquid state, then coating it onto substrates such as tissue paper, cloth, or plastic film. While its greatest advantage is its low cost, its disadvantage is that its viscosity is significantly affected by temperature. It's primarily used for various types of carton and box sealing, paper packaging, beverage bottle labels, aluminum foil sealing, flexible packaging, and other environmentally friendly paper pallets for packaging. Hot-melt pressure-sensitive adhesive tape is adaptable to a wide range of materials.
