Elmer’s Extra Strength School Glue Sticks are formulated with an increased solids content to provide a firmer initial "tack" on materials like cardboard and thick paper. While these sticks offer a stronger bond than standard school glue, they are still water-soluble and designed for safe use in educational settings. The purple color provides a visual confirmation of where the adhesive has been placed, eventually drying clear to keep your projects looking tidy.
The thicker walls of the polypropylene casing are intended to resist impact and prevent oxygen from reaching the glue. However, this high-solids formula makes the glue column more brittle if it loses moisture. If the glue becomes cold or slightly dehydrated, the internal twist mechanism can be prone to stripping if forced. For best results, the cap should be seated with firm pressure to maintain the airtight seal and prevent the product from hardening prematurely.
It is important to note that the "Extra Strength" claim refers primarily to bonding porous materials like paper. This adhesive is not designed for non-porous surfaces like plastic or metal. Additionally, the bond can degrade if exposed to high humidity for extended periods. This product is best used for craft projects where a slightly faster and stronger hold on paper is required compared to traditional school glue.
If you find that the extra strength formula dries too quickly for your needs, the standard Elmer's All-Purpose sticks offer a more traditional drying time and are available in larger quantities.
To keep your craft room organized and your glue sticks upright, you might find a solution in our rotating pencil caddies category.
