Frequently Asked Questions

Can you match my existing bag specification or competitor's product?

Yes. If you have an existing bag specification—from a competitor or previous supplier—we can replicate or improve upon it. Send us a sample or specification sheet, and our technical team will provide a quote for matching or enhanced bags. Many customers switch to us because we can either match their current specification or suggest cost-effective improvements.

What's the turnaround time for custom-printed polythene bags?

Standard custom-printed bags typically take 2-3 weeks from artwork approval (Verify). For urgent orders, we can often accommodate faster production. Lead times depend on order complexity, quantity, and current workload. We always confirm delivery dates before production begins, so you know exactly when to expect your bags.

Can polythene bags be recycled, and do you offer sustainable alternatives?

Standard LDPE and HDPE polythene bags are recyclable in most UK recycling schemes, though many end up in landfill. If sustainability is important to your business, we offer degradable and compostable alternatives including our exclusive Biofilm™ material. These break down naturally without compromising performance, making them ideal for brands committed to environmental responsibility. We can advise on the best sustainable option for your specific application.

How are custom-printed bags different from plain bags in terms of cost and lead time?

Printed bags require setup for colour printing, so they typically have longer lead times and higher unit costs than plain bags. However, the investment in custom branding often pays for itself through enhanced brand recognition and professional presentation. We offer competitive pricing on print setup, and batch printing for future orders uses existing artwork, reducing costs and turnaround time.
