FAQs - Frequently Asked Questions





Q. What is Polyethylene?
A. Polyethylene consists of long chains of the natural gas monomer, ethylene, C2H4

ethylene

How these chains are combined determines the properties of a resin.




Q. Do you make bags on a roll?
A. No.




Q. Do you make coextruded film?
A. No. AND - many "coex" films are "overspecified" and do not need to be coextruded. Often, the right single - layer, or "monolayer" film suffices with a significant savings. We have solved many challenging applications which could not be solved with " coex".




Q. How to convert diameter to layflat?
A. Diameter X 3.1416 X .5 = layflat width




Q. What is the difference between layflat tubing and rigid tubing?
A. Layflat tubing is thin flexible film which lays flat contrasted with thick, rigid pipe.




Q. Are you ISO 9000 certified?
A. No. We have many customers who are ISO 9000 compliant and we can usually provide the data you need.




Q. Your industry sells by the pound. Are there conversion formulas to figure out how much a package costs on an “area” basis?
A. Yes, click here to see the Polyethylene Film Weights and Measures page for more information.




Q. How can I save money if I pay a higher price per pound for the film?
A. By reducing the wall thickness ( gauge ), the overall cost per unit is substantially less. Contact Us to ask us how to save money.




Q. Are your products FDA as well as Kosher approved?
A. Our products are FDA as well as Kosher approved. A formal FDA and/or Kosher approval letter can be provided upon request.




Q. Are your products made from 100% virgin resin?
A. Yes, our products are made from 100% virgin resin.




Q. Do you make pallet stretch wrap?
A. No.
