How to measure a bag

 

FLAT BAGS: side seal, bottom seal, perforated rolls, header packs

DIMENSIONS: width x length
The WIDTH is measured across the opening of the bag.
The LENGTH is measured from the opening of the bag to its base.
All measurements refer to interior dimensions.

 

 

GUSSETED BAGS: side or bottom gussetA gusset is a fold on the bag that gives added depth by creating either expandable sides or bottom.

SIDE GUSSET DIMENSIONS: width x depth (side gusset) x length
BOTTOM GUSSET DIMENSIONS: width x length x depth (bottom gusset)
The DEPTH is measured across the gusset (side or bottom) of the bag when the gusset is EXTENDED.

 

 

ZIPLOCK BAGS:

All Ziplock bags have a standard 1" lip above the ziplock closure.
DIMENSIONS: Width x length
The WIDTH is measured across the opening of the bag, inside the zipper seal.
The LENGTH is measured from the bottom of the bag to the BOTTOM of the ziplock seal.

Resins:

All our resins are available in prime, virgin Low Density or Linear Low Density Polyethylene manufactured in North America.

Thickness or Gauge

The thickness, or "gauge", of a plastic bag refers to the thickness of a single wall of the bag, generally measured in mils, or thousandths of an inch (1000 mil = 1 inch). (Note: Bags are sometimes measured in microns (mic). To convert between mils and microns: 25.4 microns = 1 mil.)

Typical Thicknesses for Low Density Bags Light weight bags: 0.8 - 1.25 mil Typical uses: Produce bags. Ideal for economical coverage of lightweight products.

Standard weight bags: 1.5 mil Typical uses: food, scratch protection, storing, display. Medium weight commercial bags: 2.0 mil Typical uses: foods, garments, shipping. Heavy weight bags: 3 - 5 mil Typical uses: parts, for shipping scuff and tear resistance.
