Rigid All Board Envelopes size CP 010.02 are 200mm x 288mm flat. Choose a capacity of up to 50mm using the pre-creased grooves to create a snug fit to protect and cushion higher value items in the post. The internal dimensions at full capacity measure 185mm x 270mm x 50mm*, ideal for all kinds of A5 size items including catalogues, photo frames, electronics and material samples that need to be kept flat in transit. It’s a cost-effective alternative to using boxes that take longer assemble, need extra void fillers and cost more in postage. Made from high quality brown E-flute corrugated card, these envelopes offer the ultimate protection from bending and crushing. The corners and edges are reinforced and each envelope includes a self-adhesive strip that makes packing easy and forms a secure permanent seal. The parcel can be opened easily using the integral tear open strip and the cardboard used even conforms to US safety standards to eliminate risk of paper cuts when packing or unpacking products. *Effective size decreases with increasing thickness
