What is a Jiffy bag made from?

The Jiffy Airkraft envelopes supplied by Kite are made from a 90gsm Kraft paper exterior with a 12 micron polyethylene coating to grant the product water resistance. This type of paper exhibits premium protective qualities and is heralded as an excellent eco-friendly option. It achieves this status by its manufacturing process omitting the excessive bleaching common in other methods of making paper, hence, using significantly less energy while maintaining greater material durability. As such, these bubble bags boast extra strength and puncture resistance, acting as highly reliable postal packaging for a range of purposes.

The interior of these padded envelopes features a fully laminated lining of astro suprabubble. This grants the entire packaging solution outstanding shock absorption and provides great internal protection for the contents of the parcel. The flat seam construction of the bags enables this bubble lining to hug the inside objects, preventing movement and promoting their safe passage through the postal system. 

What sizes of Jiffy bags are available?

At Kite, we supply 11 popular sizes to comfortably package everything from keyrings, CDs or DVDs to large A4 ring binders. Our smallest size, measuring 90 x 145mm internal dimensions, offers a snug fit to even very compact items. Therefore, the packaging grants them the highest level of protection as opposed to larger envelopes that would allow internal movement, collision and possible damage. Thus, it is important to carefully measure your objects before selecting the best Jiffy bubble bag for the job, bearing in mind that the closest fit offers the best fortification. Our handy product table also illustrates the corresponding Royal Mail PiP, giving your business full transparency regarding shipping costs so that you can calculate budgets accordingly.
