1, Odor: the smell of the paper core adhesive directly reflects the quality of the glue. A good adhesive should be an organic adhesive with a non-pungent smell. If the paper core has a pungent smell, it means the adhesive quality is poor, which not only affects the tightness of the core but also transfers an off-odor to your products and affects how your customers evaluate them.

2, Tightness: only when the paper core is sufficiently tight will it not suddenly fall apart during roll loading and disrupt the loading of the product, so be sure to check the tightness of the core when making your selection.

3, Whether the paper core is easy to store: many companies do not use the cores immediately after purchase. Established paper core manufacturers will tell customers how to store the cores and what to avoid at the time of purchase, so that mold and moisture problems do not arise.
