Flat Plastic Bags

 

Plastic Bag information from MrBoxOnline:

  • Our bags are made from polyethylene and meet FDA requirements for food applications.
  • MrBoxOnline has a broad selection of sizes and gauges to meet any need.
  • Our bags hold everything from small items to larger items requiring temporary protection in order to stay clean, fresh, and orderly.
  • All of our bags are bottom sealed for added strength.

Note:

  • In the plastic bag industry the norm for measuring bags is the width always is the first number followed by the length of the bag. 
  • For layflat bags, the third number that most often follows the length will indicate the thickness of the bag. 
  • This number will often come in Mil if the bag is made from Linear Low Density Polyethylene (LDPE) or in Micron if the material is made from High Density Polyehtylene (HDPE). 
  • If there is more than 3 numbers represented than more than likely the bag will be a gusseted bag.

How to measure a plastic bag

Plastic Bag dimensions:

  • The first dimension stated when describing a poly bag is the width. All MrBoxOnline bags measurements are inside diameter (ID).

Bag Type

  • Flat Bags
  • Side Gusset Bags
  • Bottom Gusset Bags

Measuring for Flat Bags:Width x Length  + Gauge

Measuring for Gusset Bag:Width x Side Gusset x Length  + Gauge (Note: When measuring a bag, fully open the gussett)

MEASURING FOR DRUM LINERS
  • Width = (the circumference of the drum divided by 2) + 2”. It is easiest to use a flexible tape measure and measure around the widest part of the drum.
  • Length = (height of the drum + the width [diameter]) + 4”.
  • The extra 4” provides the extra material to fold over or tie the bag.

MEASURING FOR BOX LINERS

  • Width = (the circumference of the box divided by 2) + 2”. The circumference equals the sum of the length of each side. Length = 1⁄2 the narrow width + the height of the box.
  • Add 5” to 8” extra material for fold over or tie off.

MEASURING FOR PALLET COVERS

  • Width = (the circumference of the pallet divided by 2) + 4”. The circumference equals the sum of the length of each side. Length = (1/2 the narrow width of the load + the height
  • of the load) + 2”.
