Envelope Stiffeners

 » 

Envelope Stiffeners ensure the rigidity of your envelopes, protecting documents, records, maps, pictures and more in the post.

Our strong envelope stiffeners provide much better protection than other stiffeners on the market. These strong record envelope stiffeners can easily support the weight of a full bottle of sherry. Our stiffeners prevent important items (such as documents, promotional items and vinyl records) being bent whilst in the post.
