Since 2002 when the postal service started online 1st
class mail parcel, shipping small parts the economical way.
The 3 x 5 inch size designed to fit in apartment
mail boxes, fit through door slots, under doors, and withstand impact from other parcels in the shipping system. Unlike bubble
envelopes that may not fit in the box and are not the required 3/4" thick for parcel sorting at processing facilities,
the styrofoam will meet these requirements expediting transit.
Label is printed on green paper and reduced to 78% of original size. Now that only requires
three pieces of tape across. You can print two labels on each piece of paper.
If you print a full size label, four pieces of tape are required and with
the larger size, larger items can be inside and only one label per piece of paper.
Scan Before Delivery messages are printed in the border
of the page.
small parts, key, coin, baseball card, can simply be taped on top of
the foam and the label goes directly over it
Rigid styrofoam prevents folding or stuffing
of your parcel into your mail box.
Larger parts, tools, sockets, wrenches, lightbulbs, bolts
Small parts embeded in the foam by melting out a pocket,
these lightbulbs would be crushed and broken in a bubble envelope.
