Product overview
Battery Packaging Adhesive GJ-8400 series comprises solvent-based adhesives developed for the PVC film labels that wrap dry-cell batteries. Two grades are offered. GJ-8441 is the strong-adhesive grade for double-layer PVC battery film labels, with 35% solid content and a viscosity of 2000~6000 CPS at 23 °C. GJ-8420 serves single and double PVC dry-cell labels, with 40% solid content and 3000~6000 CPS.
Both grades are formulated for anti-warping performance: the label must sit flat on the battery body without lifting at the overlap or edges, and the GJ-8400 adhesives hold the PVC film down through storage and handling. High adhesion keeps the printed PVC film firmly in place on the cell. GJ-8420 is a single-liquid type, used as supplied without a second component, which simplifies coating.
ChemPortal supplies the GJ-8400 series in wholesale quantities to battery manufacturers and to converters producing PVC battery labels. Grade selection depends on label construction: GJ-8441 for double-layer film, GJ-8420 where one grade must cover both single and double PVC labels. Technical data sheets with the full parameter table are available on request.

Frequently asked questions
Which grade should I use for my battery label construction?
Use GJ-8441 for double-layer PVC battery film labels where a strong adhesive with high adhesion and anti-warping is needed. Use GJ-8420 when the same adhesive must cover both single and double PVC dry-cell labels; it is also a single-liquid type that is easy to run.
What are the solid content and viscosity values?
GJ-8441 has 35% solid content and a viscosity of 2000~6000 CPS measured at 23 °C. GJ-8420 has 40% solid content and 3000~6000 CPS at 23 °C. Both are solvent-based and are coated on standard label lines; full parameters are listed in the technical data sheet.
What does anti-warping mean for a battery label?
PVC battery labels are wrapped tightly around a cylindrical cell, so the film tends to spring back and lift at the edges. Both GJ-8400 grades are formulated so the label stays flat and bonded without warping, which protects print quality and the appearance of the finished battery.
Is it solvent-based, and how do I order?
Yes, the GJ-8400 series is solvent-based; GJ-8420 is supplied as a single-liquid product. For wholesale pricing, container options, lead time and the technical data sheet, send ChemPortal the grade, estimated monthly volume and delivery destination, and our team will prepare a quotation.
