The original Jiffy padded bag offers excellent performance in burst strength, durability and cushioning when compared to lighter weight mailers. The tough outer paper with 100% recycled paper fibre lining and folded construction, with doubled glued bottom flap and no side seams provides high resistance against bursting and puncture. Maximum protection for items you want to ensure arrive in perfect condition.
Although a little heavier than bubble-lined mailers, with the move (at least for domestic mail) towards size, rather than weight, as the main factor is determining postage rates, there is rarely a cost penalty for enjoying the protection of a real Jiffy Bag.
A size 6 bag is the largest Jiffy bag which will fit comfortably and without taping up within the Royal Mail's new (2014) more generous 'Small Parcel' dimensions of 45 x 35 x 16 cm.
