What
is low density Polyethylene?
Polyethylene (PE) is the material used over half of all
films today, and low density polyethylene (LDPE) is the source
of most poly bags. All of out stock bags are manufactured
with LDPE for its great tensile strength, clarity, flexibility,
and water barrier properties. It is also resistant to most caustic
compounds.

What
are layflat dimensions?
For
each layflat bag, there are three dimensions. The first measurement
is the width across the opening of the bag. The length runs
from the bag opening to the base of the bag. Gauge, the third
figure in a bag's dimensions, is a measure of its thickness
expressed in mils. |

What
are gusseted dimensions?
The
width measures across the opening of the bag. The depth is
the fully extended gusset. The length runs from the opening
to the bottom, and the final dimension is the gauge (thickness). |

How
do you choose the right mil thickness?
- Lightweight
1 or 1.25 mil bags are perfect for economical packaging
and coverage of light weight products.
- 1.5
and 2 mil bags are the most commonly used thicknesses
for storing, shipping, or displaying everyday items.
- Heavy
duty 3 mil and extra-heavy 4 mil bags are capable
of protecting and supporting heavy and abrasive items.
- 6
mil bags are our toughest bags, offering total protection
for heaviest products.

How
do you inspect bag gauge?
When inspecting a bag keep in mind the polyethylene is a flexible
material, and gauge can only be measured accurately with a poly micrometer.
Machine micrometers, pinch and flatten bags or film. As gauge will
vary across the width of any bag, ask your sales person for the appropriate
weight of each case to be sure your bags are within tolerances

What
are markable bags?
Parts
bags, and bags with white block for marking, and ideal
for organizing and displaying products. Three mil bags
can handle even the toughest parts. |
