II. Which Bag To Buy
Bag makers can usually be found in the
Yellow Pages under Packaging Supply
Houses or Bags – Transparent. Salesmen
are generally knowledgeable and can give
you good advice, but you should keep the
following facts in mind:
1.
Not all plastic bags are shrink bags;
therefore, be specific. Shrink film should
always be made of virgin plastic, not
reprocessed material.
2.
Bags come in various thicknesses. The
bag thickness is measured in mils. The most
common is 5 mil. For light loads such as a
load of cookies at 100 lbs./pallet, a 3 mil
bag should be satisfactory. However, drums
of molasses, for example, at 2000 lbs./pal-
let would require 6 mils or more.
3.
Bags are made in two styles, centerfold
and gussetted. Gussetted bags shrink equal-
ly in both directions (35%/45%) and are trou-
blesome because they tend to pull up and
away from the pallet. Therefore, they should
be bought longer than the pallet height, and
special care should be taken in the bottom
shrink. Centerfold bags shrink mostly in one
direction around the pallet (60%/10%);
therefore, they don’t have a tendency to pull
up off the pallet.
4.
Bag dimensions are specified by the
lay-flat length and width. Example:
