Plastic bag size calculation guide
For lining a box
- 1) Measure the width, depth and height of the box to be lined. The depth should be the shorter side.
- 2) To determine the width (W) of the bag, add 1" to the width of the box.
- 3) To determine the depth (D) of the bag, add 1" to the depth of the box.
- 4) The length (L) of the bag is determined by adding the depth plus 1" to the height plus 1". Add another 5" to allow coverage of the box contents.
For a round container
- 1) Measure the diameter and height of the container to be lined.
- 2) To determine the circumference (C) of the container, multiply the diameter by 3.14.
- 3) To determine the width (W) of the bag, divide the circumference (C) by 2. Add 1" for a looser fit.
- 4) To determine the length (L) of the bag, add the diameter to the height. Add 5" for overhang.
For a square container
- 1) Measure the width, depth and height of the container to be lined. The depth should be the shorter side.
- 2) To determine the width (W) of the bag, add the width and depth. Add 2" for a looser fit.
- 3) To determine the length (L) of the bag, add 1/2 the depth to the height. Add 5" for overhang.
For a pallet cover
Back to top
- 1) Measure the width, depth and height of the pallet to be covered. The depth should be the shorter side.
- 2) To determine the width (W) of the cover, add 1" to 2" to the width of the pallet.
- 3) To determine the depth (D) of the cover, add 1" to 2" to the depth of the pallet.
- 4) The length (L) of the cover is determined by adding 1/2 the depth to the height.
