The invention discloses a grid PET double-sided adhesive tape and a production method thereof. The adhesive tape comprises a PET substrate, an adhesion increasing agent is attached to both surfaces of the PET substrate, the adhesion increasing agent on each surface is uniformly coated with a glue layer and a grid release paper is adhered to the glue layer. The adhesion increasing agent is attached to both surfaces of the PET substrate so that adhesion of the glue layers to the PET substrate is observably improved. The adhesive tape has good stripping performances and prevents glue residual. The double-sided adhesive tape can be torn off and be recycled. The production method is simple and feasible and has an excellent market application prospect.
