About Poly Bags

From Hardware to Food Packaging

Poly bags turn up everywhere - containing screws in hardware stores, protecting products on retail shelves, packaging food in commercial kitchens. We manufacture them here in the UK to your specification.

The Flexible Alternative

LDPE poly bags are the soft, flexible plastic bags you see everywhere - from hardware stores to supermarkets. They’re softer and more pliable than polypropylene, less optically clear but better in cold environments where stiffer materials become brittle.

We manufacture LDPE poly bags here in the UK, made to your specification rather than forcing you to choose from a limited range of stock sizes.

Industrial & Hardware

Poly bags are the standard choice for packaging parts, components, and hardware. Nuts, bolts, screws, washers, fittings - anything that needs containing, protecting, and keeping together. When you’re packing thousands of components, consistent bag quality matters - no weak seals, no film that tears when you’re trying to fill it.

Custom sizes mean bags that fit your products properly. Custom printing means your branding, part numbers, or barcodes on every bag.

Retail & Consumer

For retail applications, poly bags protect products during storage and transit, keep items clean on the shelf, and present products clearly to customers. Euro-slots for hanging displays, reseal tape for consumer convenience, tear notches for easy opening.

The translucent nature of LDPE means products are visible without the crystal clarity of polypropylene - which suits many applications where you need to see what’s inside without needing retail-grade presentation. They also work well as lightweight mailing bags for documents, catalogues, and soft goods.

Food Packaging

LDPE is widely used in food packaging - it’s moisture-resistant, food-safe, and suits products that don’t need rigid presentation. All our poly bags can be manufactured to EU 10/2011 food contact standards, and our BRCGS AA(*) accreditation means proper documentation for your audits.

UK Manufacturing

We convert here in the UK, which means lead times of 3-4 weeks rather than months. BRCGS AA(*) accredited with full traceability and compliance documentation.

For regular users, we offer call-off arrangements. Agree your annual volumes, we manufacture in efficient runs, hold stock, and you call off what you need when you need it. Better for your cash flow, better for your storage space, and you’re never caught short.
