  • This gauge of bottom weld bags eliminates tears, punctures and broken bags.
  • All bottom weld bags have bottom welded heat sealed seams - very strong.
  • We can manufacture even stronger poly bags: 700 to 1000 gauge poly bags. However, these poly bags must be made to order. They require specific machine set up and a larger order quantity. For example, 10x12" 1000g poly bags would require a minimum order quantity of 6,000 bags. For example, 36x48" 650g very big poly bags require minimum order quantity of 500 bags. All bespoke bags will have a lead time subject to current demand. Please contact us for further details.
