Frequently Asked Questions

 
Can I see a proof of my bag art sketch before production begins?
 
After receiving your design files and proofing fee, we will arrange the production of samples. Upon completion, we will send you  the images of sample and related descriptions, if you are not satisfied, we will make changes immediately.After obtaining your permission, we will be producing.
 
 
What format of art do you prefer?
 
We prefer artwork in ai (illustrator) or eps (encapsulated post script) or format. All fonts must be converted to curves, or outlines.
 
 
What’s the practical difference between Low Density (LD), High Density (HD) and Linear Low Density (LLD)?
 
Low Density (LD) is a soft poly material, which makes no noise when crumpled and has a shiny finish. This material stretches easily, therefore making it hard to puncture. High Density (HD) is a tough material that crinkles when crumpled. Due to its’ toughness, it can carry more weight in thinner gauges; however it can also be easily punctured since it does not stretch. High Density (HD) has a matte look and is easy to see through unless the material is black in color, whereas Low Density (LD) is opaque in most material colors. Linear Low Density (LLD) fits somewhere in between the LD and HD materials making it the best choice for groceries.
 
 
What’s the difference between mil and micron?
 
“Mil” is an English measurement of thickness while “micron” is a metric measurement. In general, LD bags are measured in mils while HD bags are measured in microns though they can be converted from one to the other as follows: 1 mil = 25.4 microns.
 
 
What’s the standard thickness in bags?
 
In T-shirt style bags: for HD material the standard range is 13 micron to 25 micron (equivalent to 0.5 mil to 1 mil). For LD material the standard range is 1 mil to 1.75 mil. In Die Cut or Patch Handle style bags, the standard range is 1.5 mil to 2.5 mil. In Soft Loop or Rope Handle style bags the standard range is 2.5 mil to 4 mil.
