Title:
PACKAGING TAPE USING AQUEOUS ACRYLIC ADHESIVE, AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/111844
Kind Code:
A1
Abstract:
The present invention relates to a packaging tape and a production method therefor and, more specifically, to a packaging tape and a production method therefor, the packaging tape having, as an adhesive layer, an aqueous acrylic adhesive composition in which acrylic copolymer emulsion particles are dispersed in water. The present invention improves initial adhesive strength by adding vinyl acetate and ethylene glycol into a mixture of a plurality of acrylic monomers, preparing an adhesive composition by an emulsion polymerization reaction, and drying and aging the adhesive composition after coating the adhesive composition onto an oriented polypropylene film. In addition, the present invention can enhance productivity of the packaging tape and work efficiency through a drying process of continuously moving a plurality of temperature zones, and does not generate VOC, etc. harmful to the human body during the production process or during use of the packaging tape by using, as an adhesive, an aqueous acrylic adhesive composition.
