Finding the correct bag size is a cost saving move for you. Poly bags come in varying sizes and you should know what's the best for your products. When you buy the size closest to your needs, the benefits are two fold; you save money by purchasing a smaller product and you do your part to help protect the environment by using less material.
Box Liner – Gusseted
Box lining gusseted poly bags are great for keeping the product's moisture away from the box. Large Gusseted box liners are perfect for shipping produce, frozen items and any product with moisture.
Note: Depth (D) is the shorter of the 2 sides.
1. Width (W) of the bag = width of the box + 1”
2. Depth (D) of the bag = depth of the box + 1”
3. Length (L) of the bag = height of the box + depth + 6” to allow coverage of the box contents.
Example: Box: 18”W x 12” D x 14” H
Bag: 19” W x 13” D x 33” L
Square Container – Layflat
Used in industrial, institutional and medical applications. These bin liners tear off rolls for easy use in many applications such as bin liners, gaylord liners and dust covers.
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: Container: 14”W x 10”D x 32”H
Bag: 26” W x 42” L
Pallet Cover – Gusseted
Extra large plastic bags for covering pallets during shipment. Easy to use, just slips over the top of the pallet and drops down to cover the entire product. Widely used to cover pallets that will store inside or outside. Also great for shipping to and from various locations. Pallet covers protects your product(s) from the weather, dust, paint, water, snow, and other types of debris.
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: Pallet: 40”W x 36”D x 50”H
Cover: 42” W x 38” D x 68” L
Measuring for a Re-closable Poly Bag
A re-closable poly bag is any bag manufactured with a standard zip track closure or slider zip closure. Also known as Ziplock bags, resealable bags, zip lock plastic bags and secure bags. Resealable bags have a number of applications ranging from food storage, small parts, manufacturing, electronics and many others.
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 ½” 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 ½” to 2” to both dimensions for a looser fit.
Example: For a flat product 3½” wide by 5½” deep, the bag dimensions should measure at least 4” W x 6” L.
Measuring for a Slider Top Bag
Slider top poly bags provide a highly protective barrier against moisture and vapors. Delay evaporation and dehydration to preserve freshness and taste of packaged foods. Polypropylene bags make great ways for storing food, electronics manufacturing, hospitals, agriculture, clean room technology flat poly bags can be used virtually anywhere.
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 1½” 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 ½” to 2” to both dimensions for a looser fit.
Example: For a flat product 2½” wide by 5½”deep, the bag dimensions should measure at least 4” W x 6” L.
