Are your poly bags recyclable or eco-friendly?

Can I get custom printed bags with my logo?

What's the difference between HDPE and LDPE?

HDPE (high-density polyethylene) is stiffer and more puncture-resistant, used for grocery bags and heavy-duty industrial applications. LDPE (low-density polyethylene) is more flexible and clear, common for zip bags, retail bags, and mailers. We’ll recommend the right material based on your product and application.

Do you supply food-safe poly bags?

Yes. Food-grade LDPE and HDPE options are available for direct food contact applications. FDA-compliant materials throughout. We’ll confirm food-contact suitability for your specific application before quoting.
