Which adhesive is typically used for bonding paper and cards?

The appropriate adhesive for bonding paper and cardboard is PVA (polyvinyl acetate). PVA is a versatile adhesive that is non-toxic and dries clear, making it ideal for use on porous materials such as paper and cardboard. It forms a strong bond as it seeps into the fibers of the materials being bonded, creating a durable connection that is essential for projects involving paper crafts, bookbinding, or anything where a clean and precise finish is required.

Hot glue, while it can bond paper and cardboard, is generally not the best choice for these materials; it dries quickly but can create a bulky bond that may affect the appearance and feel of the finished product. Contact adhesives are more suited for materials that need an instant bond and are often used for heavier materials or surfaces requiring a flexible bond. Wood glue, specifically formulated for porous surfaces like wood, isn't appropriate for bonding paper-based materials as it typically requires the surfaces to be heavily porous to work effectively.

In summary, PVA is the most suitable adhesive for paper and card because of its strong bonding capabilities, clear drying properties, and suitability for the specific needs of paper crafting.
