Traditionally used Industrial paper tube The (barrel) glue mainly includes gelatin, gelatinized starch (including oxidized starch and modified starch), polyvinyl formal liquid (107) adhesive, polyvinyl acetate lotion (white latex), PVA solution, etc.

Among them, gelatin and starch adhesives are basically not used due to their low bonding strength and short storage period; The biggest disadvantage of polyvinyl alcohol adhesive is its poor water resistance. The compressive strength of industrial paper tubes decreases significantly with increasing storage time. Although it can be partially improved after acetalization, it still cannot meet the requirements; The water resistance of polyvinyl acetate lotion is better than the previous adhesives, but its main disadvantages are low initial adhesion, poor compressive strength and creep resistance of bonded industrial paper tubes.
