Contract Bag Conversion Services

What We Offer

Contract bagmaking converts your printed reels into finished bags. If you’re a converter with capacity constraints, a printer without bagmaking equipment, or a packaging reseller needing a manufacturing partner, we can turn your film into production-ready packaging.

We’ve been converting flexible films for four decades, serving fellow converters, packaging resellers, and distributors who need reliable bag conversion without the capital investment in their own equipment.

Looking for finished bags rather than contract conversion? See our bag products.

Why Converters Use Contract Bagmaking

Overflow capacity - Your lines are running flat out and you can’t fit another job in. Rather than turn work away or push lead times out, we can take the bagmaking while you focus on what your facility does best.

Specialist constructions - You print brilliantly, but you don’t have the equipment for wicketted bags, or your setup doesn’t handle gusseted bags efficiently. Send us the printed reels and we’ll handle the conversion.

Equipment downtime - Machines break down, maintenance windows overrun. Contract bagmaking keeps your customers supplied while you sort things out.

No capital investment - Bagmaking equipment represents significant capital outlay. Contract conversion gives you access to multiple bag types without tying up cash in machinery.

Market volatility buffer - When lead times stretch and raw materials become uncertain, having a converting partner with 300-400 tonnes of packaging films in BRC-certified warehousing provides a valuable backup.

Bag Constructions

Side weld bags - The simplest construction with seals on both sides and an open top. Sizes up to 1100mm x 900mm. Suited to a wide range of products and packing methods, from bakery and food-to-go through to retail and industrial applications. See our side weld bag products.

Wicketted bags - Side weld bags mounted on wire wickets for high-speed automatic packing lines. Essential for bakeries and food manufacturers running automated equipment. We produce 250 bags per wicket as standard. See our wicketted bag products.

Side gusseted bags (also known as crimp bags) - Bags with folded gussets on each side that expand when filled, creating a block-bottom appearance on shelf. Widths from 65mm to 400mm, lengths up to 1000mm, gusset depths from 10mm to 150mm. Popular for confectionery, pet food, snacks, coffee, and products requiring good shelf presence. See our side gusseted bag products.

Back seal bags - Pillow-style bags with a seam running down the back, available in both lapseal (overlapping seal) and finseal (fin-style seal) configurations. Sizes up to 400mm x 1000mm. The construction gives a clean front face for retail presentation. See our back seal bag products.

Bottom gusseted bags - Bags with a gusset at the bottom that allows them to stand upright when filled. Side sealed construction with robust seals. See our pouch products.

Back Seal Tubing

For customers running their own form-fill-seal equipment, we offer contract back seal tubing. We convert your printed flat film into tube stock - the same lapseal or finseal construction as our back seal bags, supplied on rolls ready to feed your packaging line.

This service suits converters who have FFS capability but not tubing equipment, or who need additional tubing capacity during busy periods. Flat widths up to 400mm, on 76mm cores. See our layflat tubing products.

Functional Features

Beyond the basic bag construction, we can add features to suit your packing requirements and retail presentation:

Wickets - Wire wicket mounts for automatic packing lines. Standard configurations to suit most automated equipment.

Euroslots - Punched hanging slots for retail display hooks. Bags hang cleanly on shop fixtures for maximum shelf presence.

Tear notches - Small cuts in the bag edge for easy consumer opening. A small detail that makes a significant difference to user experience.

Hang holes - Round or shaped holes for alternative hanging display options.

Perforation - Hot needle microperforation from P1 to P360 for products needing breathability. Lets bakery products stay crisp, keeps produce fresh, prevents condensation in chilled display.

The specific features available depend on the bag type and construction. Let us know what you need and we’ll confirm what’s possible with your specification.

Materials We Convert

We have experience converting most flexible packaging films into bags:

Polypropylene films including BOPP (plain, metallised, pearlised, coated) and CPP. Our bread and butter - we convert polypropylene films every day.

Polyester films including PET for applications requiring heat resistance, ovenable packaging, or additional strength.

Polyethylene films including LDPE and HDPE where flexibility and conformability matter.

Laminates including multi-layer structures and barrier films for products needing extended shelf life or specific barrier properties.

Specialty films including NatureFlex, biodegradable BOPP, and other sustainable substrates for customers with environmental requirements.

Different materials behave differently during bagmaking - seal temperatures, handling characteristics, and achievable tolerances all vary with the substrate. Our operators understand these differences and adjust parameters accordingly.

Quality and Food Safety

Every job goes through inspection. We check seal integrity, bag dimensions, and feature placement before dispatch. If we spot any issues with incoming material - damage, contamination, print defects - we’ll let you know before processing.

We maintain clean processing conditions appropriate for food-grade materials. Our facility is BRCGS AA(*) accredited - the same global food safety standard recognised by GFSI and required by major retailers. Full batch traceability, audit-ready documentation, and compliance certificates delivered when you need them.

Order Quantities and Lead Times

Minimum order quantity is approximately 100kg of material. Setup charges apply for smaller runs to cover changeover time. For larger or regular orders, setup costs are absorbed into the run.

Standard lead time is 3-4 weeks from receipt of material. For urgent requirements, rush processing is available - call us to discuss what’s possible given current workload.

If you have ongoing requirements, we can set up call-off arrangements. You commit to quantities over time, we schedule production efficiently, and you call off what you need when you need it.

Specifications

Detailed specifications depend on bag type, material, and construction. Rather than quote generic ranges that may not apply to your specific requirements, we prefer to discuss your needs and confirm what’s achievable.

Standard reel core size for unwind is 76mm (3”). If your reels are wound on different cores, let us know and we’ll confirm compatibility.

What We Need From You

To quote a contract bagmaking job, we need:

• Material specification - film type, thickness, any coatings or treatments
• Reel details - width, core size, outside diameter
• Bag construction - side weld, wicketted, gusseted, back seal, etc.
• Bag dimensions - width, length, gusset depth if applicable
• Features required - wickets, euroslots, tear notches, perforation pattern
• Quantity - number of bags or total linear metres of film
• Any special requirements - packing format, delivery schedule

If you’re sending material to us, include handling notes for sensitive films or materials with specific storage requirements.

Getting Started

Send us the details of what you need converting and we’ll provide a quote - typically within 24 hours. If you’re exploring options or not sure which construction suits your application, call us and we can talk through the possibilities.

For ongoing contract work, we’re set up to be a reliable converting partner - predictable quality, consistent lead times, and the flexibility to accommodate your production schedule.
