Layflat tubing is usually used for a square container.

• 1. Width (W) of the bag = width + depth of the container + 2" for a looser fit.
• 2. Length (L) of the bag = height of the container + half of the depth to the height. Add 5" for overhang.

Example: For a container 14" W x 10" D x 32" H, the bag should measure at least 26" W x 42" L.

Gusseted bags are usually used as pallet covers.

Note: Depth (D) is the shorter of the 2 sides.

• 1. Width (W) of the cover = width of the pallet + 1-2"
• 2. Depth (D) of the cover = depth of the pallet + 1-2"
• 3. Length (L) of the cover = height of the pallet + half of the depth

Example: For a pallet 40" W x 36" D x 50" H, the cover should measure at least 42" W x 38" D x 68" L.

A re-closable poly bag is manufactured with a slider zip closure.

• 1. Measure Length (L) from the bottom of the bag to the base of the re-closable seal.
• 2. Measure Width (W) of the bag from side to side.
• 3. For rigid items, add .5" to the Width (W) of the bag to allow the item to fit through the opening.
• 4. For thick or bulky items adjust dimensions accordingly.
• 5. Add 0.5" to 2" to both dimensions for a looser fit.

Example: For a flat product 3.5" W x 5.5" D, the bag should measure at least 4" W x 6" L.

Slider top poly bags provide a highly protective barrier against moisture and vapor.

• 1. Measure Length (L) from the bottom of the bag to the bottom of the slider closure.
• 2. Measure Width (W) of the bag from side to side.
• 3. For rigid items, add 1.5" to the Width (W) of the bag to allow the item to fit through the opening.
• 4. For thick or bulky items adjust dimensions accordingly.
• 5. Add 0.5" to 2" to both dimensions for a looser fit.

Example: For a flat product 2.5" wide by 5.5" deep, the bag should measure at least 4" W x 6" L.
