Expandable envelopes

There are two types of expandable envelopes available: with expandable sides or expandable sides and bottom (RBD). Envelopes of this type are a special solution intended for sending bigger amounts of mail or for the storage of documents. After putting the parcel inside the envelope, its sides or sides and bottom are expanded and in this way, its capacity increases several times. Moreover, paper weight is higher than standard, which guarantees increased tear resistance of the envelope and as a result, the parcel is protected against damage.
