About Side Weld Bags
The Workhorse of Food-to-Go Packaging
Side weld bags are flat bags with welded side seams and a folded bottom. Simple, effective, and endlessly versatile - they're the standard choice for bakeries, cafes, and food-to-go operations across the UK.
Made to Specification, Delivered on Time
If you’ve been buying side weld bags from importers, you know the frustrations. Long lead times that stretch when containers get delayed. Minimum orders that tie up cash for months. Quality that varies batch to batch. And when something goes wrong, nobody to call who can fix it.
We’re a family-owned UK converter with four decades in flexible packaging. We manufacture side weld bags here, which means 3-4 week lead times you can plan around, custom specifications without container-sized minimums, and people who answer the phone and understand what you need.
Options That Suit Your Application
Side weld bags aren’t one-size-fits-all. A bag for crusty bread needs different perforation than one for sandwiches. A retail display bag needs a euro-slot. A premium product deserves custom print.
Perforation to let products breathe - micro-perforation for bakery items and fresh produce, macro punched holes for higher airflow, or strip perforation for specific breathability zones.
Reseal tape - peel-and-seal adhesive strip for quick sealing without heat sealers. Customers can reseal after opening too.
Euro-slots for retail hanging displays. Tear notches for easy opening.
Custom printing up to four colours in-house, up to ten through our print partners. Your branding, your messaging, your product information.
Anti-mist film for chilled display - keeps products visible rather than hidden behind condensation.
All bags are made to your specification. Sizes up to 1100mm x 900mm, thicknesses from 20μm to 50μm (25μm BOPP being our standard), in materials including CPP, LDPE, and sustainable options like PLA and NatureFlex.
Platter bags for catering - large flat bags sized to slide a full sandwich platter, wrap platter, or pastry selection straight in. Professional presentation for corporate catering, events, and hospitality.
UK Manufacturing
Being UK-based means predictable lead times - typically 3-4 weeks from order to delivery. No waiting for containers, no customs delays, no wondering where your stock is.
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.
Wicketted Bags
For bakeries and food-to-go operations using wicket dispensers, we hold a range of standard sizes in stock - ready for quick dispatch. See our wicketted bags page for stock sizes and specifications.
Beyond Food
Side weld bags work just as well for non-food products. Greeting cards, stationery, small gifts, craft supplies - anything that needs clear presentation and protection.
Food-Grade Compliance
All our side weld bags are manufactured to food-contact standards, EU 10/2011 compliant. BRCGS AA(*) accreditation means full traceability and documentation for your audit requirements.
Whether you’re a high-street bakery, university catering operation, or supermarket supplier, the compliance documentation is there when you need it.
