Abstract

The invention discloses a method for preparing a low-toxicity BOPP adhesive tape. The method comprises the following operation steps: (1) performing extruding granulation on polypropylene resin, melamine cyanurate, colopholic acid, erucyl amide and titanium dioxide by an extruder to prepare master batches, and then making the master batches into a BOPP film; and (2) brushing the BOPP film with a prepared low-toxicity glue, and performing slitting and winding after the glue is completely dry to prepare an end product. The prepared low-toxicity BOPP adhesive tape is transparent in appearance, uniform in color, strong in bonding strength, resistant to piecing and good in tearing resistance, particularly, cannot give out pungent smells, is non-toxic and environment-friendly, and can be used in large scale in the food package industry.

Description

technical field [0001] The invention belongs to the technical field of BOPP adhesive tape preparation, and in particular relates to a preparation method of low-toxicity BOPP adhesive tape. Background technique [0002] BOPP tape is based on BOPP biaxially oriented polypropylene film. After heating, the pressure-sensitive adhesive emulsion is evenly applied to form an adhesive layer ranging from 8μm to 28μm, forming a BOPP tape master roll. It is a light industry enterprise and company. , Indispensable supplies in personal life. At present, the scope of application of BOPP tape is more and more extensive, and it has also been widely used in the food packaging industry. However, the preparation materials of common BOPP tapes on the market have a certain The pungent odor will have an adverse effect on the health of consumers. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a preparation method of lo...
