When using polyester (PET) and polypropylene (PP) hand strapping to prepare and stabilise goods for transit or storage, strapping seals and buckles are often essential to ensure a tight seal for adequate strap tension. Low tension can lead to a risk of containers toppling and the items within becoming broken or damaged. Our semi-open galvanised metal seals slide over strapping with ease, and can be secured using a tensioner and sealer, or a combination tool. Kite Packaging stocks two other variants of seals for strapping and the type you need will very much depend on the application. The serrated metal strapping seals meanwhile work much like our galvanised seals, but comprise serrated treads to the inside which grip to heavy duty/polyesters (PET) strapping, for an even stronger seal and our plastic buckle seals are an easy-to-use alternative to metal seals, and do not require an additional tool to seal straps. These buckles are for use with PP strapping only.
