Craft glue is a white, nontoxic PVA glue that is safe for all ages to use. What is PVA glue? PVA stands for polyvinyl acetate. That means the glue is both colorless and odorless.
Craft glues – like Aleene's Original Tacky Glue – are best used for craft and hobby projects. If you need super strong adhesion on heavy surfaces, you'll want to use an industrial-strength formula like Aleene's The Ultimate or Aleene's Super Gel. Most craft glues are ideal for paper surfaces, lightweight woods, foam and non-washable fabrics.
